The present invention relates to cultivation systems, in particular, modular cultivation systems featuring a vertical hive (V-Hive) Green Box that can maximize crop productivity within an available volume of space of a growing unit or structure.
People all over the world are drawn to living in cities because cities, quite simply, are the world's undisputed economic engine. Just 600 cities today account for about 60 percent of the global economic output. By 2025, the world's top 600 cities will be home to an estimated 220 million more people of working age and will account for more khan 30 percent of the expansion of the potential global workforce. The biggest economic transformation the world has ever seen is occurring today simultaneously with the population expansion of cities in emerging markets, generating millions of new consumers with rising income and whose spending power will change the way the world shops—including people living in cities buying more of their food locally.
The projected rise in today's global population is approximately 7 billion to 9.5 billion by 2050. This projected rise in global population demands an estimated 70 percent increase in food production from current levels by 2050, necessitating a doubling in crop production from 10 billion tons to 20 billion tons by 2050. Given that agriculture already makes use of almost half of the land surface of the planet, consumes over 70 percent of all current freshwater withdrawals worldwide, and expends 30 percent of the global energy demand to food production and its supply chain, it is easy to see that a doubling of crop production will put enormous pressures on land, water and energy resources worldwide, particularly in arid and semiarid regions of the world. Cities, with their infrastructures and centralized planning for supplying water and energy as well as for treating and reusing wastewater and even generating renewable energy, lend themselves to organized and potentially more efficient utilization of water and energy for crop production.
Urban agriculture takes on several forms, including establishing community gardens on vacant lots and, more recently, rooftop greenhouses. Vertical Farming constitutes a third form of urban agriculture. Vertical Farming is generally defined as “the production of crops in vertically stacked growing shelves or trays typically in an enclosed warehouse-type of environment.” Vertical Farms typically employ hydroponics technology, or soil-less agriculture, through which crops are grown in liquid nutrient solutions. The crops are also provided either exclusive or supplemental electric lighting using fluorescent lamps or light-emitting diodes (LEDs). Technology improvements achieved over the years, particularly in lighting technology, have improved the production capacity of Vertical Farms.
Due to the association of the concept of Vertical Farms, fairly or unfairly, with grand architectural designs of awe-inspiring and often futuristic-looking edifices, the prospects for Vertical Farms in recent years have been significantly diminished by their projected high costs, particularly on account of the prohibitive costs of the buildings needed to house the actual farms. Thus, to devise a new strategy for designing and developing vertical farms that can achieve economic feasibility, it has been crucial to decouple the concept of vertical farms from conventional buildings to which they became inadvertently intertwined. Vertical Farming may be employed as a highly promising strategy of urban agriculture to help achieve food security in perhaps most of the world's multiplying mega-cities. Vertical Farming may be designed as either low-tech or high-tech; however, it needs to achieve a certain level of sustainability economic, environmental and social—for it to succeed. The following are two crucial strategies that are designed to help Vertical Farming attain economic, social and environmental sustainability.
SANE Test
Each Vertical Farming enterprise must satisfy the SANE Test to achieve economic and social sustainability: S—Safety of Fresh Food, A—Access to Fresh Food, N—Neighborhood Building and Strengthening, and E—Equity Generation and Growth.
S—Safety of Fresh Food:
Vertical farming operations must continuously maintain and preserve their ability to satisfy the all-important demand for safety and quality of fresh produce. For example, a major factor that has been enabling Vertical Farm enterprises to make rapid and successful inroads in China is the series of high-profile food contamination cases that have scandalized China's citizens in recent years, fueling the demand in cities all over China not only for fresh produce, but also for scalable crop production systems that are demonstrably safe.
A—Access to Fresh Food:
Vertical farms in and around cities should not only collapse the distance that fresh crops travel from the farm to the dinner table, which, in the United States for example, is typically from 1,500 miles to within 100 miles, but should also help make possible the elimination of myriads of food deserts, defined as urban areas in which it is difficult to buy affordable, nutritious and good-quality fresh crops owing to the lack of grocery stores, farmers' markets and healthy food providers. Vertical farms should improve access to fresh crops in urban areas in terms of both geographic access and economic access.
N—Neighborhood Building and Strengthening:
Vertical farms should foster community building and strengthening by encouraging community participation and involvement in its production operations, promoting food and environmental education among the community's residents and students, etc. Each Vertical Farm should not only become an integral part of its community, but each Vertical Farm should deliberately make the community it belongs in an integrated ecosystem unto itself—economically, socially and environmentally.
E—Equity Generation and Growth:
Vertical Farms must generate and grow financial equity to its owners, investors, employees and the whole community.
Implementing Cuello's Law (Analog of Moore's Law) to Improve Resource Productivity of Vertical Farms
There is a crucial need to propel the Vertical Farming industry into achieving further significant improvements in its resource productivity. With the prodigious pressure on the planet to double crop production by 2050 to meet the enormous food demand of 9.5 billion people then—when today almost half of the planet's land area is already being used for agriculture, two-thirds of the Earth's available fresh water is already being used for food production, and as much as 30 percent of the world's energy expenditure is devoted to agriculture and the food supply chain—producing food with less land, less water, less nutrients, less energy and greater yield has become a pressing global imperative. Fortunately, the ultimate potential of Vertical Farms is that they can produce fresh crops with less land, less water, less nutrients, less energy and greater yields.
Moore's Law is the observation that the number of transistors in a dense integrated circuit doubles approximately every two years. More than a mere observation, Moore's Law also became a projected goal for the semiconductor industry that led to the design of ever more powerful integrated circuits that have made today's electronic and internet technologies possible and ubiquitous. Analogous to Moore's law, Cuello's Law is the projected goal that crop productivity with respect to resource use in a tech-dense indoor farm (including Vertical Farm) should double every four to five years. This means that at least every half a decade in the next 10 years, tech-dense Vertical Farms should achieve a doubling of crop productivity per unit land area, per drop of water, per pound of nutrients and/or per kiloWatt of energy. Cuello's Law simply articulates the great need of which most in the Vertical Farming industry are already keenly aware. Cuello's Law aims to serve as a unifying clarion call and a challenge to the Vertical Farming industry to further innovate and help meet this century's massive food demand while securing resource sustainability.
Any feature or combination of features described herein are included within the scope of the present invention provided that the features included in any such combination are not mutually inconsistent as will be apparent from the context, this specification, and the knowledge of one of ordinary skill in the art. Additional advantages and aspects of the present invention are apparent in the following detailed description and claims.
The present invention features a Vertical Greenbox Solution as a new paradigm or strategy for designing Vertical Farms to achieve economic feasibility. The Vertical Greenbox Solution, also known as the Non-Building Vertical Farms (NB-VF), pertains to vertical farms constructed without using standard or conventional buildings, but using minimally-structured, modular and prefabricated structures that would be capable of supporting agricultural operations.
Without wishing to limit the invention to a particular theory or mechanism, the Vertical Greenbox Solution paradigm prescribes the following three critical features: (1) Minimally-structured—reduced materials; reduced total weight; reduced load-bearing requirement; reduced plumbing and electrical services; (2) Modular—uniformity of growing space, hardware and environmental control; consistency of operational procedures; interchangeability of units; allows use of varied growing systems; allows development of turn-key operations; and (3) Prefabricated—allows off-site construction and assembly of modules; and significantly lower cost in construction and labor. None of the presently known prior references or work has the unique and inventive technical features of the present invention.
As will be described herein, the present invention features a Vertical-Hive Green Box (or V-Hive Green Box), which is a modular cultivation system that may be used in a modular Vertical Farm or Plant Factory, though it can also be used in a warehouse-type or greenhouse-type of vertical farm or plant factory. The principal design advantage of the V-Hive Green Box is that it maximizes the quantity of crops that can be grown within the available volume of space in a modular unit, warehouse or greenhouse per unit time. In other words, the V-Hive Green Box maximizes crop productivity within the available volume of space of the growing unit or structure.
In preferred aspects, the principal structural components of the V-Hive Green Box include a frame, a growing board (G-board) with cultivation trays/tubes, and a lighting board (L-board) with the light sources, such as light tubes or lamps. The V-hive Green Box may further include an aquaculture board (A-board) configured for use in aquaponics. The dimensions of the V-Hive Green Box may be adjusted to fit an available volume of space in a Vertical Farm or Plant Factory modular unit, which may be a shipping container, thereby maximizing crop productivity within the available volume of space in the Vertical Farm or Plant Factory modular unit.
As will be described herein, at least three types of V-Hive Green Boxes, namely, a V-Hive Crop Green Box, a V-Hive Aquaponics Green Box, and a V-Hive Aquaculture Green Box. The V-Hive Crop Green Box may include G-Boards and L-Boards. The V-Hive Aquaponics Green Box may combine hydroponics and aquaculture (or fish culture) and, thus, includes G-Boards, L-Boards and A-Boards. Lastly, the V-Hive Aquaculture Green Box only makes use of the A-Boards.

In one embodiment, as shown in
In some embodiments, the V-hive aquaculture green box (105) may further comprise one or more pumps operatively (176) connected to the aquaculture boards (150) for circulating the fluids to and from, and within the rigid tank (152). In other embodiments, the aquaculture board (150) may further comprise one or more air spargers (154) operatively connected to the rigid tank (152) for aerating the water. In still other embodiments, as shown in
In some embodiments, any of the systems described herein may utilize alternative energy sources to power the electrical components of the system. For example, the light sources, pumps, and digital components may be powered by solar or wind energy solely, or in combination with power from the power grid. This may further reduce the energy usage and cost of Vertical Farming. In alternative embodiments, the fluids from the aquaculture boards may be used to fertilize the growing boards. For instance, when used aquaculture fluid, which contains nutrient-rich fish emulsions, is renewed with fresh water, the used aquaculture fluid may be stored in the reservoir (170) for future use to water and fertilize the crops. This may also further reduce the water and fertilizer usage and costs of Vertical Farming.
Without wishing to limit the invention to a particular theory or mechanism, the modularity of the system provides significant convenience in installation and removal of the growing system within the modular Vertical Farm. It also provides significant convenience in the scale up of production through the addition or removal of modular units. Further still, the orthogonal and lateral movements of the G-Boards, L-Boards, and A-boards, as well as the relative movements of the growing trays/tubes on the G-Board and the light sources on the L-Board, lend themselves conveniently to automation and remote control. The V-Hive Green Box design also makes its crop cultivation protocols in terms of lighting, nutrient delivery and overall optimization amenable to automation and remote control.
The following is a non-limiting example of the present invention. Equivalents or substitutes are within the scope of the invention.
Case Study: Arizona Cats in the Greenbox
Southern Arizona has a number of areas that can be categorized as “food deserts.” The U.S. Department of Agriculture defines food deserts as areas of the country that are lacking or devoid “of fresh fruit, vegetables, and other healthful whole foods, usually found in impoverished areas. This is largely due to a lack of grocery stores, farmers' markets, and healthy food providers.”
As a solution to mitigate the food insecurity in food-desert neighborhoods and regions in Southern Arizona, the Arizona Cats in the Greenbox project has been established to design and implement sustainable intensive production of high-value crops (e.g., lettuce and microgreens) in movable, used shipping containers, each named the Arizona Green Box, in accordance with the principles of the Vertical Green Box Solution. The Arizona Green Box, which are modular and movable shipping-container hydroponic boxes, can constitute an innovative, practical and cost-competitive strategy to grow and deliver fresh vegetables to food deserts, especially given that conventional greenhouses remain costly to build. They can also serve as effective focal-point activity for such areas that could foster community cohesion and building.
Without wishing to limit the invention to a particular theory or mechanism, a standard-sized shipping container provides the following significant advantages in implementing movable and modular controlled-environment hydroponic boxes: 1) Economical—about $2,000 or less per unit; 2) Easily procured; 3) Movable and easily transported, whereas a greenhouse building is typically fixed in location; 4) Modular with standard size, thus, the configuration and arrangement of hydroponic cultivation systems inside a unit can be customized, optimized and standardized to be identical for all other units; 5) Scalable—the modularity of the unit lends itself to convenient scalability through simple unit multiplication; 6) Convenient control of physical environment on account of the modularity of the unit; 7) Can be stacked vertically one on top of the other if needed to save land area; and 8) Easily secured.
The Arizona Green Box is a sustainable, movable and modular method of controlled-environment hydroponics crop production that can save as much as 80 percent of water compared with conventional farm production and supplies renewable power to its crop lighting system using solar photovoltaic (PV) panels. Because it is movable and modular, shipping-container controlled-environment crop production, such as the Arizona Green Box, lends itself readily to applications including emergency food aid during famine or for natural disaster relief.
