This invention relates to climate change, weather control, cloud-seeding and drought relief. It specifically relates to cloud-seeding with DMS (dimethylsulfide) and/or its oxidation products. The invention further relates to the release of DMS by marine algae such as Emiliania huxleyi (hereinafter E. huxleyi or EHUX), a species of marine algae which is one of Earth's primary producers of DMS. It further relates to ocean grazers which eat marine algae such as EHUX, and to the sharply increased quantities of DMS which the algae release when they are mechanically stressed or attacked by ocean grazers [Evans, et. al., 2007]. It especially relates to humanity's need to globally amplify DMS release by marine algae such as EHUX in order to seed rain-clouds and effect both targeted and general drought relief in the face of increasingly adverse and accelerating climate change.
Protracted drought, crop failure, famine, and forced animal and livestock herd reduction (or die-off) are among the most devastating impacts of global warming, and they are likely to get worse, becoming increasingly prevalent, and significantly more widespread across the interiors of multiple continents, as warming and climate change progress in the 21st century [Allison, et. al., 2009, and Solomon, et. al., 2007]. Warming raises ocean evaporation rates globally, which adds moisture to the atmosphere. The added water vapor is a potent greenhouse gas (GHG) which further accelerates global warming in a positive feedback loop. However, increased moisture doesn't necessarily lead to increased average rainfall. In fact, with global warming, the opposite can occur. Increased drought may result in many regions, despite increased average global atmospheric humidity. The reason is that one of the primary natural cloud-seeding agents, DMS release from marine algae, may decline faster than atmospheric humidity rises with accelerating climate change.
In addition to increased ocean evaporation, global warming leads to increased stratification of warming ocean waters, producing a more pronounced ocean thermocline which blocks upwelling of nutrients from volcanic rifts in the deep ocean floor. This leads to greater depletion of nutrients in the warmer ocean surface waters and a corresponding decrease of average global algal blooming [Lovelock, 2006], including a decrease in EHUX blooming and a corresponding reduction in DMS release. Since DMS is a primary planetary cloud-seeding agent, its reduction may lead to a decrease in average rainfall in many parts of the world, especially in drought-prone regions, and an increase in global drought and famine, despite higher average atmospheric moisture levels as global warming progresses [Lovelock, 2006].
Drought is regionally spreading in many locations around the world. It is also intensifying, occurring more frequently, and lasting longer. It is expected to get far worse as global warming progresses. A tipping point for upward-spiraling positive feedbacks and setting irreversible, runaway warming in motion, with increasingly punishing drought, including mega-drought, accelerating global crop failure (leading to a rise in global famine), and accelerating forced herd reduction (or die-off) being anticipated as atmospheric carbon dioxide rises above 450 ppm [Lovelock, 2006, and Hansen, et al. 2008, 2009]. As the primary driver of climate change, carbon dioxide (CO2) emissions are currently about 11 GtC/yr (carbon measure in billion metric tons carbon per year); the accumulation of atmospheric CO2 has reached 400 ppm (the highest level in 13 million years); and the accumulation is increasing at about 2 ppm/yr while CO2 emissions continue to rise at about 3.5% annually [Keeling, et. al., 2013, Solomon, et. al., 2007, Allison, et. al., 2009, McGee, 2013, and Rapier, 2012]. In an unchecked scenario, we calculate (and IPCC reports concur) that atmospheric CO2 accumulation will reach a 450 ppm tipping level by ˜2029 for irreversibly seeding runaway warming and catastrophic climate change.
Intervention is needed to prevent carbon dioxide from reaching the 450 ppm tipping point. Further intervention is needed to increase DMS production to stimulate cloud-seeding and bring rains and drought relief as long as elevated carbon dioxide levels persist. Accelerated global DMS production is anticipated to be necessary for at least the next 60 years.
Our calculations indicate that, if global carbon dioxide emissions are capped at 12 GtC/yr by 2023, and then reduced to 6 GtC/yr by 2050, further reduced to 3 GtC/yr by 2062, and finally stabilized at 1 GtC/yr by 2078 primarily via a combination of nuclear energy and invention-derived clean fossil-fueled energy and transportation alternatives, energy and fuel conservation, and improvements in energy and fuel efficiency, along with sweeping changes in agriculture, while concurrently invention-geoengineering-capturing an average of 10 GtC/yr (global impact basis) carbon dioxide from the atmosphere each year from 2025-2070 (with capture ramp-up from 2019-2025), accumulated carbon dioxide levels in the atmosphere will be capped at ≦425 ppm by 2023, the 450 ppm tipping point may be (narrowly) averted, and atmospheric carbon dioxide may be restored to the (pre-industrial) level of 280 ppm by 2075. That will solve the carbon dioxide problem and substantially reduce drought in the long term, but extra drought relief will still be needed during the interim correction period (2019-2075), and possibly for some time afterward (owing to thermally-lagged equilibration delay). Invention-enhanced global DMS production will be needed to seed clouds, bring rain, and provide drought relief to semi-arid lands through at least 2075, and possibly longer. Invention-enhanced soil moisture retention will also be needed to maximize the effectiveness of rain and prevent rapid soil moisture loss by unimpeded runoff of rain water before it appreciably benefits crops.
The invention includes a fossil-fueled system and process for stimulating, and massively amplifying, heavier-than-water marine algae blooming such as EHUX blooms (hereinafter EHUX) in the oceans, yielding correspondingly amplified capture of atmospheric carbon dioxide (CO2) at sea, and simultaneously triggering elevated DMS release by also invention-inciting ocean grazer attacks on the ocean-amplified EHUX blooms, at their bloom peak. It also includes means of targeting amplified DMS release from offshore EHUX blooms, or inland release of remotely produced DMS, to specific drought-stressed regions of the world and timing the amplified DMS release to coincide with on-shore (or inland) moisture-bearing winds to effect cloud seeding (and rain-making) over the drought-stressed regions during agricultural growing seasons. The invention involves large-scale, fossil-fuel combustion-CO2 fed, land-based, salt-water bioreactor production of EHUX plus auxiliary inland salt-water bioreactor production of ocean grazers such as zooplankton or krill. A minority fraction of the bioreactor EHUX will be fed to ocean grazers in auxiliary inland salt-water bioreactors to stimulate grazer production and also stimulate inland release of DMS in drought-stressed regions, or to stimulate inland production of DMS for collection, concentration, and transport to remote drought-stressed regions. A majority fraction of the bioreactor EHUX will be shipped to seaports for distribution and ocean seeding (with optimal nutrient) across ˜70% of the oceans to stimulate much larger secondary EHUX blooming and correspondingly amplified capture of atmospheric carbon dioxide at sea. Amplified secondary EHUX blooming will yield extra DMS release at sea and, as nature's primary cloud-seeding agent, the extra DMS should induce extra ocean cloud cover to be driven inland by onshore winds. This will help precipitate inland rain and alleviate drought. If desired, extra EHUX blooming and DMS release may be concentrated along the windward coastlines of drought-stressed and famine-prone countries with the extra DMS release being synchronized with developing weather patterns, the appearance of onshore winds, and the agricultural growing season.
Each ton of carbon in fossil-fuel combustion-CO2 fed invention bioreactor EHUX seed blooms will seed ˜14 more tons of atmospheric carbon capture (51 tons, CO2 measure) at sea, effecting an approximate 15× ocean amplification factor and massive invention-induced CO2 capture from the atmosphere. That is the means by which 10 GtC/yr (carbon measure) of atmospheric CO2 capture may be sustained from 2025-2070, enabling a return to 280 ppm atmospheric CO2 by 2075 (substantially reducing planetary greenhouse warming and associated drought in the long term) if emissions are also capped at 12 GtC/yr by 2023 and then reduced to 1 GtC/yr by 2078.
A fraction of that ocean-amplified 10 GtC/yr of EHUX blooming may be seeded along the windward coastlines of drought-stressed countries. Invention inland-bioreactor-produced ocean grazers may also be introduced in elevated numbers offshore—along the same coastlines in order to incite focused, directed, well-timed, and massively amplified grazer attacks at the peak of ocean-amplified EHUX blooming, thereby stimulating maximal secondary DMS release. If ocean-amplified DMS release is induced by well-timed invention-orchestrated grazer attacks on invention-amplified EHUX blooms concentrated along the windward coastlines of drought-stressed countries, rain should develop—sweeping inland to provide much-needed drought relief. Famine may be reduced or even eradicated by this means.
Release of DMS from well-placed land-based invention bioreactors should also help to bring rain to drought-stressed regions that are further inland, if it is properly timed with developing moisture fronts or periods of increased humidity in developing weather patterns. Invention bioreactors may finally produce DMS remotely, where it may be collected, concentrated, and transported for release in distant drought-stressed lands.
Fossil-fueled two-stage, 15× ocean-amplified EHUX blooming, correspondingly elevated DMS release at sea, capture of 10 GtC/yr of atmospheric carbon dioxide, fossil-fueled inland DMS production and release, and fossil-fueled inland DMS production with collection, concentration, transport, and remote release are all envisioned by the invention. These are key ingredients for interim drought relief and long term drought eradication. Another key ingredient will be invention-induced enhancement of soil moisture retention.
The first three points above pertain to (pending) U.S. patent application Ser. No. 13/999,195 (hereinafter “Ser. No. 13/999,195”). The latter three points summarize the current invention, which is a CIP of Ser. No. 13/999,195 that builds on the technology and processes established by the first invention (Ser. No. 13/999,195). The fossil-fueled invention combination has several stages. The first stage (Ser. No. 13/999,195) encompasses means for globally restoring 280 ppm atmospheric CO2 two centuries earlier than best-effort emissions-control-only, for re-establishing ideal ocean pH, and for creating global drought relief by reducing global CO2 emissions, and by concurrently capturing atmospheric CO2 at an unprecedented rate. The second stage (the current application—a CIP of Ser. No. 13/999,195) simultaneously orchestrates elevated release of DMS (nature's own cloud-seeding agent). Fossil-fueled two-stage amplified ocean algal blooming (Ser. No. 13/999,195) is the critical element required to deliver necessary CO2 capture capacity. Concentrated land-based-source CO2 would be captured and bioreactor-converted to marine algae such as Emiliania huxleyi (EHUX) for elevated ocean seeding (along with optimal nutrient) and accelerated secondary EHUX blooming, enabling massively ocean-amplified CO2 capture (Ser. No. 13/999,195) and increased DMS production at sea. Carbon-free energy and reduced transportation emissions alone, without simultaneous aggressive atmospheric CO2 capture, are insufficient to avoid impending 450 ppm CO2 tipping point crossings by about 2034. Fossil-fueled, invention-orchestrated, ocean-amplified CO2 capture, however, has the potential capacity and would impart a large negative carbon footprint to energy and transportation (Ser. No. 13/999,195), while also imparting a substantial DMS release profile (current CIP application). High-carbon fuel precursors and energy sources burning fossil fuels would supply concentrated CO2 to invention bioreactors, yielding large harvests of high-density marine algae (e.g., EHUX) needed to seed secondary ocean blooming on a much larger scale and corresponding maximally amplified capture of atmospheric CO2 at sea. Each ton of CO2 from concentrated, fossil-fueled, land-based sources such as CCS (carbon capture and sequestration) coal-fired and CCS gas-fired power plants, CCS cement production, and CCS building heating, plus CO2 from hydrogen production by CCS natural-gas reformation and by CCS oil and coal-gasification syngas reactors, would drive amplified capture of up to 14 tons of CO2 at sea (Ser. No. 13/999,195). Invention-produced two-stage amplification would impart a large negative carbon footprint (Ser. No. 13/999,195) and a substantial DMS release profile (current CIP application) to the largest traditional CO2 sources, spectacularly transforming them from CO2 emitters and drought instigators into primary engines for global warming reversal (Ser. No. 13/999,195) and drought/famine eradication (current application). Beneficial invention utilization of CO2 byproduct from hydrogen production would promote environmental viability and could vault H2 to a front-runner position in alternative fuels development. Invention-amplified secondary ocean blooming of E. huxleyi can also amplify DMS release at sea—the highest DMS levels occurring during invention-orchestrated attacks by ocean grazers. Timely introduction of extra grazers at the peak of amplified E. huxleyi (EHUX) blooming would maximize DMS release (nature's primary rainmaker). Concentrating this along the windward coastlines of drought-stressed continents and synchronizing it with developing weather patterns during agricultural growing seasons could bring much-needed rain and early drought relief. Inland DMS production by feeding a fraction of invention bioreactor-produced EHUX to ocean grazers, contained by adjacent inland secondary invention bioreactor stages, may be collected, concentrated, and transported for release over remote drought-stressed regions. That is another invention means of producing much-needed rain and drought relief in many parts of the world.
Soil moisture retention may be improved by spreading organic matter (including highly porous calcified components) on agricultural soils, in the form of excess (dead) invention bioreactor EHUX and (dead) zooplankton grazers from secondary-stage invention bioreactors. Live inland-grown cultures would be transported for use at sea to seed secondary ocean blooms and ocean-amplified capture of atmospheric CO2, plus DMS release at sea, but the dead fraction may be invention-utilized inland as organic fertilizer and as spreads for soil moisture retention enhancement, which is almost as important (for drought and famine relief) as rain itself.

No. 13/999,1965 spin-off basis elements for CIP spin-off invention involving DMS production, rain-cloud seeding, enhanced soil moisture retention, drought-relief, and famine relief, with an appended list of CIP inclusions following thereafter in this section.

54. The invention further includes the process of preceding section 51, wherein local forced re-aeration of previously seeded areas to an appropriate depth prevents post-bloom anoxia from secondary bacterial blooming.
55. The invention further includes the process of preceding section 51, wherein the seeding of amplified ocean blooming is restricted to the vast open ocean that is further out from shore, well beyond the realm of coastal waters and beyond the shallow coastal-shelf sea floor, out in the open seas where much deeper water prevails, wherein species-selective bloom dominance and rapid sinking quickly carry the dead algae below the ocean thermocline of the open seas and all the way to the deep-sea floor, wherein deep ocean temperatures at the deep-sea floor are quite low—near to zero degrees centigrade, and wherein low deep-sea temperatures preserve the dead algae and slow and/or suppress the onset of secondary bacterial action, algal decay, eutrophication, and post-bloom anoxia which would otherwise deplete ocean-dissolved oxygen, and wherein the slowing or suppression of bacterial action at low temperature at the deep-sea floor delays the onset of eutrophication and post bloom anoxia to an extent enabling ocean sedimentation, often referred to as marine “snow”, to essentially bury the dead algae before post-bloom anoxia or eutrophication can develop.
56. The invention further includes the process of preceding section 55 wherein the onset of post bloom anoxia is further delayed by calcareous exoskeletal armor plates of E. huxleyi, a preferred heavier-than-water algae for ocean amplification; and wherein delay by calcareous exoskeletal armor plating dominates dead algal blooms, owing to the species-selective bloom dominance of E. huxleyi enabled by high seed levels from land-based bioreactor seed sources, and further enabled by phosphate-depleted nutrients supplied during ocean seeding with E. huxleyi seed grown in land-based bioreactors.
57.

134. A process of ocean-amplified CO2 capture and amplified release of dimethylsulfide (DMS, a natural cloud seeding agent) at sea, wherein algae plus nutrient are seeded into the ocean instead of nutrient-alone; the process comprising: land-based capture of concentrated CO2 from a land-based CO2 source; land-based conversion of captured CO2 to heavier-than-water marine algae in at least one bioreactor configured to encourage the rapid growth and reproduction of the heavier-than-water marine algae as ocean seed; transport of the heavier-than-water marine algae as ocean seed to seaports for ocean distribution and dispersal with added nutrients in order to seed ocean-amplified blooming (further growth and rapid reproduction at sea—essentially secondary blooming on a vast ocean scale); attack on the secondary ocean algal blooms by ocean grazers such as zooplankton and krill (as nonlimiting examples) who eat the secondarily bloomed algae—causing the algae to release DMS at sea; wherein the ocean-amplified algal blooming occurs essentially selectively for the heavier-than-water species of marine algae by virtue of the heavier-than-water marine algae being distributed, dispersed, and seeded into the ocean water at higher levels than existing natural buoyant ocean algae, the higher levels selectively accelerating ocean blooming rates of the heavier-than-water marine algae by virtue of seeding the ocean with marine algae seed harvested from the at least one land-based bioreactor, wherein ocean seeding occurs higher than normal on a nonlinear algal growth curve and produces a species-selective dominance of the ocean algal bloom, wherein the higher that the ocean blooming starts on the growth curve, the faster it proceeds, if sufficient nutrient is present or provided, and wherein the ocean grazers are selected from among a group of ocean grazers consisting of ocean grazers naturally occurring in the ocean and a culture of ocean grazers produced by inland bioreactors, in which the ocean grazers produced by the inland bioreactors are transported for release at the ocean algal bloom site.
135. The process of inclusion 134 in which the species-selective ocean algal bloom dominance is further enhanced by nutrient selection, and in which nutrient selection for E. huxleyi coccolithophorid marine algae blooming includes nutrients which are deficient in phosphate, wherein phosphate deficiency, while other nutrients are concurrently provided in abundance, promotes prodigious E. huxleyi growth at sea, essentially to the exclusion of blooming by other species of marine algae, including buoyant algae, in the seeded ocean area.
136. The process of inclusion 134, wherein transport to seaport of the heavier-than-water marine algae seed, and/or transport to seaport of the ocean grazer culture produced by inland bioreactors, occurs by flat-bed truck, flat rail car, or barge; wherein the flat-bed truck, flat rail car, or barge carry the marine algae seed, and/or the ocean grazer culture produced by inland bioreactors, in stasis-supporting cargo containers which are transferrable by crane or other lifting means from one flat-bed transportation means to another, and wherein the cargo containers are designed to maintain conditions in support of a healthy stasis condition for the heavier-than-water marine algae seed and/or the ocean grazer culture produced by inland bioreactors.
137. The process of inclusion 136, wherein the stasis-supporting cargo containers may be loaded onto ocean freighters docked at seaports, the ocean freighters then distributing the stasis-supporting cargo containers to floating seed and/or ocean grazer culture repositories at sea; wherefrom the stasis-supporting cargo containers may be transferred to dispersal boats which fan out from the floating seed and/or ocean grazer culture repositories to disperse and dispense the heavier-than-water marine algae seed (plus nutrients) and/or ocean grazer cultures produced by the inland bioreactors into the ocean for ocean-amplified algal blooming to proceed, along with ocean-amplified atmospheric CO2 capture as the heavier-than-water marine algae bloom prodigiously at sea, and for a fraction of the ocean-amplified marine algae bloom to release large amounts of DMS as the algae are eaten by the ocean grazers, and wherein a preferred embodiment of the invention involves delaying ocean-introduction of the ocean grazer cultures produced by the inland bioreactors until the ocean-amplified marine algal bloom has appreciably matured and already captured substantial amounts of atmospheric CO2 in the process of blooming.
138. The process of inclusion 137, wherein the nutrient doses are metered to support heavier-than-water ocean-amplified algal blooming up to the light penetration (algal opacity) limit and then run out.
139. The process of inclusion 138, wherein the ocean-amplified bloom dies a death selected from among a group of death categories consisting of death by starvation after the metered micro-nutrient doses run out or death by being eaten by ocean grazers; wherein death by being eaten by ocean grazers causes algal release of DMS, and wherein the dead heavier-than-water amplified bloom loses motility and residual (uneaten) dead algae sink rapidly, clearing the ocean photic zone before the end of each month and enabling restored light penetration into the photic zone to support another amplified bloom following a next month's seeding.
140. The process of inclusion 139 in which algal blooming and DMS release proceed with up to 12 batch algal blooms/year being seeded and achieved, with each ocean-amplified batch algal bloom approaching the light penetration (algal opacity) limit before it is eaten by grazers or dies of starvation and sinks, and in which accumulated amplified ocean blooming yields up to 14 GtC/yr of heavier-than-water algae (correspondingly capturing 14 GtC/yr of atmospheric CO2) globally for each 1-3 GtC/yr of seeding with land-based heavier-than-water algae seed produced by the land-based bioreactors, wherein the predominant heavier-than-water ocean algal bloom species are determined by the species of land-based bioreactor seed algae harvested from the bioreactor, and wherein the bioreactor seed algae are dominated by initially preseeding the bioreactor with a purified culture of the desired marine algae species, and wherein the desired marine algae species are selected from a group consisting of coccolithophore (e.g., E. huxleyi) and siliceous diatoms.
141. The process of inclusion 139, wherein the seeding of amplified ocean blooming and DMS release are restricted to the vast open ocean that is further out from shore, well beyond the realm of coastal waters and beyond the shallow coastal-shelf sea floor, out in the open seas where much deeper water prevails, wherein species-selective bloom dominance and rapid sinking quickly carries the uneaten fraction of dead heavier-than-water algae below the ocean thermocline of the open seas and all the way to the deep-sea floor, wherein deep ocean temperatures at the deep-sea floor are quite low—near to zero degrees centigrade, and wherein low deep-sea temperatures preserve the uneaten fraction of dead algae and slow and/or suppress the onset of secondary bacterial action, algal decay, eutrophication, and post-bloom anoxia which would otherwise deplete ocean-dissolved oxygen, and wherein the slowing or suppression of bacterial action at low temperature at the deep-sea floor delays the onset of eutrophication and post bloom anoxia to an extent enabling ocean sedimentation, often referred to as marine “snow”, to essentially bury the dead algae before significant post-bloom anoxia or eutrophication can develop.
142. The process of inclusion 140, wherein approximately 1 GtC/yr of seed algae triggers amplified ocean blooming of up to 14 GtC/yr of heavier-than-water algae and correspondingly elevated DMS release; but wherein approximately another 2 GtC/yr of seed algae are needed to satiate marine grazer appetites (among naturally occurring grazers), producing early DMS release, so that the satiated naturally occurring grazers leave the approximately 1 GtC/yr of seed uneaten so that it remains to trigger the amplified ocean blooming of the up to 14 GtC/yr of heavier-than-water algae and corresponding photosynthetic and/or coccolithogenic (calcification) capture of up to 14 GtC/yr of atmospheric CO2, and in which ocean seeding with approximately 3 GtC/yr of algal seed produced by land-based bioreactors provides both the 2 GtC/yr of algae to satiate the grazer appetites, producing an early DMS release, and the remaining 1 GtC/yr of uneaten seed that remain to trigger the amplified ocean blooming of the up to 14 GtC/yr of heavier-than-water algae, optionally followed by later DMS release upon delayed introduction of the bioreactor-produced grazer cultures.
143. A process in which algae is fed to fish farms, brine shrimp tanks, or tanks of other small marine life to raise schools of the small fish, brine shrimp, or other marine life comprising predators which prey on ocean grazers, and the small fish, brine shrimp, or other marine life are transported and released to control grazer populations at sea.

145. An algal bioreactor in which liquid shearing forces are applied to bloomed algae, the mechanical stress of the shearing force causing bloomed algae to release DMS without being attacked by grazers.
146. An algal bioreactor in which sonication stresses bloomed algae, the sonication stress causing bloomed algae to release DMS without being attacked by grazers.
147. An algal bioreactor in which a combination of sonication and liquid shearing forces (e.g., as applied by a Polytron-type or Tekmar-type homogenizer) stress bloomed algae, the combination sonication and liquid shearing force stress causing bloomed algae to release DMS without being attacked by grazers.
148. An algal bioreactor in which microwaves stress bloomed algae, the microwave-induced stress causing bloomed algae to release DMS without being attacked by grazers.
149. An algal bioreactor in which blender blades stress bloomed algae, the blender-blade stress causing bloomed algae to release DMS without being attacked by grazers.
150. An auger-based, slinging sheet fountain algal bioreactor from Ser. No. 13/999,195 in which the bioreactor auger speed is increased to stress bloomed algae, the auger-speed stress causing bloomed algae to release DMS without being attacked by grazers.
151. An auger-based, slinging sheet fountain algal bioreactor from Ser. No. 13/999,195 in which the auger rotation is halted and grazers are added to the bioreactor after the algal bloom has reached maturity, the grazers then eating the algae, resulting in DMS release.
The remainder of
The figure includes prior-art, Ser. No. 13/999,195 invention, and current CIP invention elements. Items 30-37 comprise a prior art methane reformation system in which natural gas (methane—30) is injected into steam (33, 34) which (in two stages) cracks off the carbon in the prior-art reformation process, leaving a 2nd stage prior-art mixture of CO2 and H2. Separation stages (35) isolate the hydrogen for compression (36) and use as a transportation fuel (37) for hydrogen powered vehicles (38) which are illustrated as an automobile in this nonlimiting example. At this point, prior art ends. The Ser. No. 13/999,195 invention segment begins with isolating CO2 as a compressed gas, liquid, or super-critical fluid (SCF-CO2, 40).
Ser. No. 13/999,195 invention stage (39) isolates CO2 as a byproduct of methane reformation, and removes it (40) in the form of compressed CO2 (not illustrated), liquid CO2, or supercritical fluid (SCF-CO2, illustrated—40) in an invention separation stage (39) into purified components H2 (37) and CO2 (40). The hydrogen (H2) may be used to fuel transportation (37, 38) and the CO2 may be compressed and/or liquefied as super critical fluid (40, SCF-CO2). The SCF-CO2 may be stored (13), decompressed (14-17), and converted to salt water algae (18), and continuously harvested (20) for distribution to the next stage (stage-2, operations at sea), exactly as in
The remainder of
Curve (81) is the anticipated stage-2 15×-amplified ocean CO2 capture response enabled by 1 GtC/yr invention ocean seeding (82). Essentially, 14 GtC/yr of amplified natural ocean capture (CO2) is expected from 1 GtC/yr of invention seeding. Additional accounting for anticipated land-based capture of 3 GtC/yr raises the curve (81) total land-and-sea fair-weather, contingency capture rate to 17 GtC/yr, as required earlier by
Referring to
The separation tank (100) is relatively large diameter to cause a significant reduction in flow velocity at the same flow rate as 101. This velocity reduction is important, because it suddenly offers the tiny algae (e.g. 2 μm in diameter and having flagella for motility in a nonlimiting E. huxleyi example) an opportunity to swim against the current, if they so desire. What is needed next is a reason for the algae to swim against the current so that they will concentrate in the upper end of the separation tank. That impetus is provided by tank (100) and its main downward flow path being dark and essentially devoid of both CO2 and nutrient, whereas an attractant light beam (beacon 106, 107) is positioned within the mouth of a harvest exit tee (105) located near the upper extent of tank (100). With the main separation tank volume (100) and path (101→102) being essentially devoid of light, and with the flow velocity significantly reduced at large tank diameter, the algae may swim against downward current (101→102)—swimming upward instead toward the attractant beacon (107) and illuminator globe (106) supplied at the mouth of the harvest exit tee (105). The exit tee and harvest exit path (105) are smaller in diameter again and, even though the exit path (105) flow rate is low, this diameter reduction raises flow velocity (relative to path 101→102) enough that any algae which appear at the mouth of the exit tee (106, 105) will be sucked into harvest exit flow path (105). Marine algae may be continuously harvested as ocean seed at the harvest output of the silo. The harvest port (1) of

Oxygen produced during photosynthesis is continuously removed by an oxygen removal system (119, 110-116) based on at least one oxygen-permeable membrane (116), which is tubular in the nonlimiting
This stage-1 invention bioreactor system (90) may be considered a pseudo-anaerobic bioreactor since oxygen is removed (119) as fast as it is produced by photosynthesis. Algal blooming will therefore proceed under pseudo-anaerobic conditions which will enhance bloom rates, because oxygen otherwise acts as a photosynthetic inhibitor (above a certain point), and its continuous removal (119) will accelerate blooming.
Items 90-119 and 21 are the same as invention Ser. No. 13/999,195 used to produce algal seed at ports (20) of reactors (65) in
This is a multi-stage invention system comprising a multiplicity of individual stage-1 inventions or an initial prior-art concentrated carbon dioxide source combined with at least one of the individual stage-1 land-based invention capture and algae conversion systems and stage-2 invention process-enhanced ocean-amplified capture, in which all stages (and the
Note: In order for multiple, globally-distributed copies of the multi-stage CO2 capture and storage system to restore the atmosphere to 280 ppm CO2 by 2075, global emissions need to be capped at 12 GtC/yr by 2023 (Ser. No. 13/999,195) and gradually reduced to 6 GtC/yr by 2050, 3 GtC/yr by 2062, and 1 GtC/yr by 2078, in addition to multi-stage Ser. No. 13/000,195 system contingency capture of 17 GtC/yr CO2 and 10 GtC/yr impact capture continuously each year from 2025-2070 (or within about 2 years of that interval), and permanent safe storage of the accumulated capture form (˜0.45 tera-tons, carbon measure which is ˜1.65 tera-tons CO2—converted to marine algae which gets eaten and/or sinks to the bottom of the ocean and gets buried by ocean sedimentation). This global emissions cap and reduction schedule will be achieved, in part, from more diligent and widespread application of certain prior-art technologies and practices such as clean-coal (CCS) and nuclear energy, with smaller contributions from wind and solar energy, energy efficiency and conservation, and in part from re-forestation and sweeping changes in agriculture (especially 3rd world agriculture), agricultural product usage, and the western diet, transportation (e.g. fuel efficient and/or electric cars), travel (increased teleconferencing and reduced business air travel), and commuting practices (living closer to work, increased carpooling, and greater use of mass transit). Items listed in the preceding sentence are all prior-art, with more diligent and widespread application required to contribute substantially to the Ser. No. 13/999,195 global emissions cap and reduction schedule. Ser. No. 13/995,195 targets will also be achieved, in substantial part, by converting a major fraction of transportation to hydrogen (H2) fueling by about 2050. Hydrogen-powered vehicles already exist in prior-art, such as the Honda FCX-Clarity (a fuel-cell car operating on hydrogen). What doesn't exist in prior art is a significant source of hydrogen fuel (or means of making it), enough to fuel a substantial fraction of all transportation by 2050 without releasing CO2 in hydrogen production. Prior-art solar energy systems may be used to generate hydrogen by electrolyzing water, but solar energy is only viable where abundant sunshine exists and that excludes most of the industrial world. Prior-art natural-gas (methane) reformation is the primary means of today's hydrogen production, but methane reformation releases CO2 as a major prior-art byproduct.
In our multi-stage invention, the concentrated CO2 byproduct of hydrogen production by natural-gas reformation, oil gasification, and/or coal gasification will be converted to high density marine algae in stage-1 invention silos (
Note: In some embodiments, portions of the multi-stage invention system may be borrowed from prior-art and from Ser. No. 13/999,195 and then incorporated into a new larger CIP invention system for relieving drought and famine. Prior-art items and Ser. No. 13/999,195 items are not separately claimed in this CIP, and CIP invention claims only involve them as components of a larger invention system and/or of a globally-distributed multi-stage CIP invention combination system, which larger CIP invention system and/or multi-stage CIP combination system is (at once) novel, non-obvious, and desperately needed for simultaneously avoiding impending near term 450 ppm CO2 tipping points, for restoring 280 ppm CO2 by 2075, setting the stage for subsequent global warming reversal and the elimination of ocean acidification, and ultimately for eliminating drought and famine. In addition, some portions of the larger CIP invention and/or the multi-stage CIP combination involve device claims and other portions involve process claims. This mixture of device and process claims is required in a single CIP patent application in order to present the case and demonstrate the potential for an overall 17 GtC/yr CO2 contingency capture and 10 GtC/yr impact capture (Ser. No. 13/999,195), which are both required to offset global emissions anticipated to reach 12 GtC/yr by 2023, thereby enabling the stage to be set for gradual reversal of global warming, and for ocean-amplified DMS production, inland DMS production and release, seeding of ocean cloud-cover to cool and shade oceans, seeding of polar cloud cover to shade and cool polar ice sheets in summer, seeding of rain-clouds in semi-arid drought-stressed lands, and for soil moisture retention enhancement in semi-arid lands.
Stage-1 is land-based capture of 1-3 GtC/yr CO2 (
These multi-stage invention systems relate to global climate change, ocean acidification geo-engineering, more specifically to global climate restoration, ocean revitalization, and fueling ultra-clean transportation with hydrogen (H2), more specifically yet to drought and famine relief, and finally to primary and secondary global cooling and polar ice stabilization. Climate restoration would be achieved by capturing (Ser. No. 13/999,165) the greenhouse gas carbon dioxide (CO2) from Earth's atmosphere significantly faster than it is produced, and doing that over an extended period, e.g. from 2025-2075. The recommended collective capture rate by globally distributed copies of our multi-stage invention is 17 GtC of CO2 per year contingency (fair-weather capture rate) and 10 GtC/yr net impact rate each year from 2025-2070, in order to reduce Earth's atmospheric accumulation of CO2 to the ideal (pre-industrial) level of 280 ppm (parts-per-million) by 2075.
(Note: The Ser. No. 13/999,195 system 17 GtC/yr contingency capture target, 10 GtC/yr net impact target and Ser. No. 13/999,195 accumulation impact assume global CO2 emissions would be capped at 12 GtC/yr by 2023 and then reduced to 6 GtC/yr by 2050, 3 GtC/yr by 2062, and 1 GtC/yr by 2075.)
Total multi-stage capture of CO2 for the period 202-2070 would amount to approximately 0.45 tera-tonnes (450 billion metric tons, carbon measure), which is 1.65 tera-tonnes (actual CO2 measure), and permanent safe storage for that much captured CO2 is a further requirement for safely reducing Earth's atmospheric accumulation to 280 ppm CO2 in the 21st century.
The multi-stage Ser. No. 13/999,165 invention systems relate more specifically yet to selectively amplified ocean algal blooming for large scale (14 GtC/yr) photosynthetic and/or coccolithophore calcification capture of CO2 by accelerated ocean algal blooming (
The CIP invention systems relate even more specifically to spin-off technology from Ser. No. 13/999,165 which allow spin-off benefits in the realm of amplified DMS release, seeding of ocean cloud cover to shade and cool the oceans (providing yet another secondary cooling benefit to both planetary climate and polar ice stabilization) via cloud albedo cooling, seeding of rain-clouds at sea which are driven inland by onshore winds, and direct seeding of inland rain-clouds for drought and famine relief in semi-arid lands. The CIP invention systems also relate specifically to the production of organic fertilizer and agricultural soil spreads that enhance soil moisture retention in semi-arid lands. The CIP invention improvement of soil moisture retention is almost as important as invention rain-making in semi-arid lands. The overall benefits in meeting U.N.-projected need for a 60% increase in food production by 2050, world-wide famine relief, and significantly boosting the global agricultural economy are expected to be enormous.

No. 13/999,195 multi-stage system relates to cement production in which an optimized Type #1 stage-1 invention captures cement production byproduct CO2 as SCF-CO2 or liquid CO2 in a third embodiment (not shown) and imparts a negative carbon footprint to the cement production by transferring captured cement production byproduct CO2 to the multiple invention bioreactors (18) where it is rapidly converted by the bioreactor accelerated photosynthesis and/or coccolithogenesis to the desired form of marine seed algae at a rate contributing substantially to the stage-1 land-harvest (up to 3 GtC/yr total), the substantially negative carbon footprint being imparted to the cement production by the up to 3 GtC/yr of the stage-1 invention bioreactor seed algae being transported to sea-ports (
In the CIP portion of the cement production invention, marine algae produced by bioreactor 18 is introduced (1) into tank (2) which contains a culture of live marine grazers that eat the marine algae. Voracious grazer attack causes the marine algae to release prodigious quantities of DMS, which is volatile and rises in tank (2), to exit at port (3), further rising in the atmosphere and photo-oxidizing to form DMSO which seeds rain-clouds (4). Live ocean grazer harvest may be taken at output 5. Excess algae and grazer harvests (20, 5, and/or detritus (dead) or waste organic material outputs (not shown—see

Referring to
Photosynthetic and/or coccolithogenic (calcification) acceleration (accelerated algal blooming) will be due in further part to exceptionally high seed levels of the coccolithophore or siliceous diatom algae introduced into the invention bioreactor algae pool (94), the seed levels for constant blooming in the invention bioreactor being unusually high—up to 15% solids (by weight) in a non-limiting example, and this will radically accelerate blooming by continuously operating the bioreactor exceptionally high on the (upward-bending) nonlinear growth curve. Normally, this solids level would exceed optical opacity limits and photosynthesis could not proceed, owing to lack of light penetration, however a novel invention optical thinning effect (see below) will circumvent prior-art opacity limits.
In
A second smaller transfer auger (not shown) will be turned on and operated to continuously remove algae suspension from the bioreactor as fast as it blooms (in excess of 15% solids). In one non-limiting embodiment, the funnel shaped silo floor would enable excess bloom removal at outlet 99. The concept here is that high seed levels (15% solids) drive very high bloom rates, but outlet 99 removal of excess bloom from the bioreactor occurs as fast as it develops, leaving a constant seed level of 15% solids behind in the reactor. This is a continuous reactor which doesn't require reseeding, once the solids level reaches 15% and the transfer auger (not shown) is turned on to keep it from going higher by continuously removing excess bloom at 99. As excess bloom is removed from the bioreactor (99), water, buffer, and nutrient are continuously replenished (21), but no new algae seed is required—enough seed remains behind from the bloom, if the transfer auger removal rate (99) is balanced exactly at the bloom level and it isn't turned on until the bloom level first reaches 15%. The transfer auger then removes excess bloom continuously (as fast as it develops), without diminishing the 15% solids level, which then becomes the continuous seed level.
The transfer auger removes 15% algae suspension to an adjacent separation tank (100). The separation tank (100) is relatively large diameter to cause a significant reduction in flow velocity at the same flow rate as 101. This velocity reduction is important, because it suddenly offers the tiny algae (e.g. 2 μm in diameter and having flagella for motility in a nonlimiting E. huxleyi example) an opportunity to swim against the current, if they so desire. What is needed next is a reason for the algae to swim against the current so that they will concentrate in the upper end of the separation tank. That impetus is provided by tank (100) and its main downward flow path being dark and essentially devoid of both CO2 and nutrient, whereas an attractant light beam (beacon 106, 107) is positioned within the mouth of a harvest exit tee (105) located near the upper extent of tank (100). With the main separation tank volume (100) and path (101→102) being essentially devoid of light, and with the flow velocity significantly reduced at large tank diameter, the algae may swim against downward current (101→102)—swimming upward instead toward the attractant beacon (107) and illuminator globe (106) supplied at the mouth of the harvest exit tee (105). The exit tee and harvest exit path (105→20) are smaller in diameter again and, even though the exit path (105→20) flow rate is low, this diameter reduction raises flow velocity (relative to path 101→102) enough that any algae which appear at the mouth of the exit tee (106, 105) will be sucked into harvest exit flow path (105). Marine algae may be continuously harvested as ocean seed at the harvest output of the silo (20). The bioreactor is continuous, self-concentrating, and will promote prodigious algal blooming at output (20). About 85% of the algal bloom will continuously exit via the harvest path (105) in a nonlimiting example, with about 15% recirculating via path (102-104). Any dead algae will sink and may be periodically removed at (109).
In an alternate embodiment, heavier-than-water algae from the bioreactor may proceed to an adjacent settling tank after blooming, in which the settling tank replaces the aforementioned separation tank; and in which settling tank conditions are maintained that do not encourage algae to swim against a current, and in which the heavier-than-water algae instead sink toward a funnel shaped harvest exit port at the bottom of the settling tank, and in which optional recirculation of clarified liquid near the top of the settling tank is provided back to the main bioreactor, with top-water clarification occurring as the algae sink to the funnel shaped bottom, and in which a concentrating effect is achieved via sedimentation of the sinking algae prior to their exit at the harvest exit port.
In both embodiments, a pH buffer (e.g., phosphate buffer, in a nonlimiting example) added (21) to the algae pool (94), buffers the pool against acidification (carbonation) from high level headspace CO2. Buffering the pH at nominally 8.2 will maximize coccolithophore algae blooming and prevent softening or acidic dissolution of the coccolithophore exoskeleton (CaCO3). As algae is continuously harvested (20) as a concentrated suspension, replenishment sea water or salt water, nutrient, and pH buffer are provided at the replenishment inputs (21) to the silo algae pool (94).
Oxygen produced during photosynthesis is continuously removed by an oxygen removal system (119, 110-116) based on at least one oxygen-permeable membrane (116), which is tubular in the nonlimiting
This stage-1 invention bioreactor system (90) may be considered a pseudo-anaerobic bioreactor since oxygen is removed (119) as fast as it is produced by photosynthesis. Algal blooming will therefore proceed under pseudo-anaerobic conditions which will enhance bloom rates, because oxygen otherwise acts as a photosynthetic inhibitor (above a certain point), and its continuous removal (119) will accelerate blooming.
If sufficient numbers of these
Stage-2 of the multistage capture system involves
To accomplish all of that,
The invention cargo containers (73) would be stasis-supporting. In a non-limiting example, they would have a power source, built-in chillers to lower temperature to a stasis-inducing level in hot climates (or heaters in cold climates), enough nutrient (and just enough light) to keep the seed alive in stasis, and a slowly churning auger to prevent the seed from colonizing (agglomerating). The containers may be transferred by crane from flat-bed trucks to inland docks, from inland docks to flat-rail cars or barges, from rail-cars or barges to seaport docks, from seaport docks to ocean freighter decks and holds, from ocean freighter decks and holds to floating repository decks, and from floating repository decks to individual seed boat decks. Each of the aforementioned transfers can easily be made by large fork lifts, dock cranes, or deck cranes and the containers will maintain stasis-support at all stages of shipment and transfer, until the seed is dispensed into the ocean sea-lanes for enhanced stage-2 blooming.
Dispensing of seed and nutrient into sea-lanes from the seed boats will be at a measured rate while the boat is moving. In a non-limiting example, seed levels would be at least 20 mg/m3 in alternating sea lanes which are nominally 60 feet wide and 10 meters deep, which would be higher than the average natural algae levels occurring across most of the oceans south of Spain, Japan, and Seattle. This will give our high-density fast sinking seed algae a competitive advantage (among natural algae species) regarding nutrient, and ocean blooming will be dominated by the desired high-density, fast-sinking marine algae of stage-1 silo harvests (20, 72—
In one embodiment of stage-2 operations-at-sea, alternating sea lanes will be temporarily deaerated to a depth of 10 meters (in a non-limiting example) by bubbling N2 behind the seed boat as the seed and nutrient are dispensed. This will temporarily displace dissolved oxygen (but not dissolved CO2 (normal level maintained by the excess bicarbonate content of the sea)) to a depth of 10 meters (only) and a pseudo-anaerobic condition will be temporarily created in each localized sea-lane being seeded. The pseudo-anaerobic condition may accelerate blooming, especially if the algae seed are nitrogen-fixing. Adjacent lanes will be seeded two weeks out of phase with one another, so that the pseudo-anaerobic condition is both transient and localized (beneficial, rather than harmful).
Micro-nutrient will be dispensed in metered doses to support only about a 2 week bloom in each sea-lane. With the high seed level (e.g., at least 20 mg/m3) inherent with invention stage-2 seeding “algae+micro-nutrient” (in contrast to prior-art systems which dose “micro-nutrient-alone” and start their bloom from a much lower point (e.g., 0.1 mg/m3)), prodigious invention stage-2 bloom rates will occur, reaching the light penetration limit (˜400 mg/m3 in a nonlimiting example) within about 2 weeks in alternating lanes.
Grazers may eat up to ⅔ of the seed before it blooms, but that is the reported limit of their appetites at this seed level, so ⅓ should remain to bloom to the light penetration limit within 2 weeks. At this point the metered micro-nutrient doses are calculated to run out and the bloom will die. The important point is that the invention bloom is dominated by high-density algae which will lose motility (post mortem), sink, and easily clear the photic zone in time for next month's reseeding. Thus, the invention stage-2 operations-at-sea will enable 12 large ocean blooms per year, instead of just one or two blooms which is the limit of prior art systems which dose nutrient-only, start at a much lower point on the growth curve, are subject to getting eaten out (before blooming) by grazers, and even if prior-art systems could get past the grazers (which they can't), they'd bloom up buoyant strains of algae that don't sink (post mortem) or clear the photic zone at the end of a bloom cycle. A persistent floating light-block would prevent a second bloom from occurring with prior-art ocean fertilization, which will generally bloom buoyant strains of algae rather than (preferred) high-density, fast-sinking strains. Prior-art ocean fertilization systems (dosing micro-nutrient-only) would, under the most favorable of conditions (where grazers don't interfere—but not much chance of that happening) yield 1 or 2 blooms/year, capturing about 1½-3 GtC/yr CO2 at best.
(Note: Even natural ocean blooming during the ice-ages would have been limited by grazers and the light penetration limits imposed by buoyant natural strains, but stage-2 invention ocean blooming won't be subject to these limits.)
In contrast, the multi-stage invention system which starts higher on the nonlinear ocean algae growth curve (by seeding algae+micro-nutrient), pre-satiates grazer appetites (2 GtC/yr) so there will remain 1 GtC/yr of (net) uneaten seed remaining to bloom (after grazer feasting), and which selectively blooms only the high-density, fast-sinking strains of coccolithophore or siliceous diatom algae (seed selectively pre-grown in stage-1 bioreactors) at sea will capture a total of 17. GtC/yr to meet the curve 81 target of
The above-listed invention system enhancements are anticipated to accelerate stage-2 ocean blooming significantly beyond the ice-age blooming rates. We project acceleration will be enough to enable 12 blooms/yr and meet the performance required by curve 81 of
In one embodiment of an invention stage-2 ocean capture process, aerator boats will bubble compressed air or oxygen to within 5 meters of the sea floor in coastal waters to reaerate the lanes at the end of each monthly bloom cycle and prevent proximal post-bloom anoxia (which would otherwise greatly harm coastal marine life and raise legal objections with prior-art ocean fertilization attempts). Anoxia is typically a coastal water phenomenon which isn't prevalent in the open sea, where most of our stage-2 seeding will be done. In the open sea, re-aeration shouldn't be necessary, species-selective bloom dominance and use of heavier-than-water stage-1 algae seed will enable rapid sinking each month, sinking the dead algae quickly below the deep ocean thermocline and all the way to the cold deep sea floor, before anoxia has any chance of developing. Low deep ocean floor temperatures approaching zero degrees centrigrade and heavy coccolith plates should further delay the onset of bacterial action that could otherwise induce post-bloom anoxia. Delay may occur until sedimentation burial eliminates any further chance of developing anoxia. The localized, transient nature of invention system induced algal blooming and marine life feeding on the dead algae on the way down or at the sea floor may further suppress anoxic development.

In another CIP embodiment (
In addition to the invention bioreactors contributing significantly to climate restoration and ocean revitalization, other applications will include high capacity algal production for silage, animal feed, feed supplements, fertilizer, biofuels, agricultural runoff control, food for fish and seafood farming involving fish or mollusks which directly feed on algae, and bottom-rung food for fish farming involving predator fish (as seafood) such as compano and cobia which feed on lower marine life (e.g, brine shrimp). In the latter case, invention high capacity algal production will feed the brine shrimp in adjacent tanks, raising shrimp for secondary feeding to predator fish.
In these other applications, the algae silos (18, 65, 90) would be used seed species optimized for silage, animal feed (or supplement), fertilizer, biofuel, agricultural runoff control, or food for fish and seafood farming and the bioreactor output (20) would be directed to those applications which end with stage-1 without sending algae for stage-2 (
Using invention bioreactors along inland lake shores and rivers, invention fresh-water algal production can further aid in revitalization of inland lakes and rivers by removal of nitrogen and phosphorus compounds added by agricultural runoff. This would be accomplished by diverting the bioreactor output (20) directly into the lake or river. In this case, it would be desirable for the bioreactor algae to be a high density, fast sinking variety of fresh water algae. The algae bloom need not be supplemented with nutrient as it is dosed into the lake or river. As the algae bloom proceeds in lakes and rivers, it will consume nutrient provided by agricultural runoff, and in doing so, it will clear the river of these agricultural pollutants. As the algae blooms die and settle to the lake or river bottom, some periodic dredging may be required to keep the main channels open and an aerator boat may need to patrol up and down the rivers and on the lakes to restore dissolved oxygen levels to prevent post-bloom anoxia as algae blooms die and sink. With re-aeration, inland freshwater algae blooms will be beneficial as they will feed the lake and river food chain and increase fresh-water fish populations which will also flourish (and be healthier for fresh-water fishermen to catch and eat) as agricultural runoff chemicals are removed.
Lake and river bacteria levels will also drop sharply as another benefit of this program. This will improve the health of fish, water birds, and essentially all creatures and humans living in or along the lakes and rivers. This includes impacting water-borne disease, the eradication or minimization of which will benefit 3rd world countries.
Clearing major rivers of agricultural runoff and bacteria will improve public health and will further stop coastal water harmful algae blooms (HAB's) such as the notorious “red tide” in Florida, which are otherwise fed from agricultural runoff at major river delta outflows. This will be accomplished by the invention high density fresh water algae having cleared the rivers of agricultural phosphorus and nitrogen compounds upstream from the delta outflow. The coastal water HAB's will simply die as their food supply will have been cut off upstream in the rivers which normally supply them with agricultural runoff. By clearing up the agricultural runoff, downstream HAB's in the gulf won't survive. By these invention means, lakes, rivers, and coastal waters will be revitalized. Even the tourism industry around lakes, rivers, and coastal waters will benefit as a result of better fishing everywhere with larger populations of bigger, healthier fish which are safer to eat as a result of growing in the cleaner, less polluted water.
