It is well known that wind power turbines can generate power that can be delivered via interconnection to existing grid systems or can be used to power individual homes, businesses and utilities. Most if not all wind power systems that are used to gather large amounts, in the Mega Watt range of power are large structure wind turbines many of which are at least 100 feet high. In the past, small wind powered turbines have also been placed high up from the ground usually at least 15 feet high. Also, most small wind power turbine systems are utilized to power a single home, business or elements of that home or business.
Currently, large wind installations in order of 100 foot or more sized turbines dot the landscape of the planet. These turbines are often positioned in remote fields out to sea or on private property away from public infrastructure. Small wind installations of turbines and other gathering devices in the 5 to 30 foot range are typically utilized in three deployments. The first deployment features clusters of small to mid sized turbines set up in remote windy areas such as the desert environment near Palm Desert in California. The second deployment features isolated powering of small homes and businesses such as those in remote artic or extreme cold climates where heating and cooling infrastructure does not exist, or is augmented at the micro use level for one home or business by small wind turbine implementation. The third deployment model features isolated powering of entities for government utilities such as isolated powering of single light stands at the Hanauma Bay National Park public parking lot in Oahu Hi.
Conventional models address power plant and isolated use models for the generation and distribution of wind power. Large turbines generate Megawatt volumes of power to be utilized locally or interconnected back to the grid system. Small wind generation systems are typically used to solve local power issues, such as street lights or home or business power needs as well as having the ability to be interconnected to a grid system for the purpose of selling the power generated by the wind gathering system to a public or private utility.
Unfortunately, the existing conventional uses have certain limitations in distribution and deployment. Large turbines have faced environmental and Defense Department concerns. Environmentalists fear that the noise and size of turbines will disrupt both scenic and habitat conditions in addition to threatening the well being of birds that may be caught in the large turbine blades. Department of Defense concerns have been raised over the large turbines interfering with radar signals and tracking. Large turbine systems that are placed far away from existing infrastructure also incur a large expense in the transportation or building of infrastructure to carry the power generated by the turbine system. Finally, the large turbine system represents a large investment for a single turbine that is a volatile investment in that if the wind is not present or wind currents change then the turbine would be viewed as a poor investment because it will not generate enough power. Also, if the turbine breaks for any reason it is going to produce zero power as it is a large and single entity. Large turbines also require labor intensive maintenance and monitoring. The life cycle for large wind turbines is 20 years and decommissioning and waste generated by manufacture, installation and decommissioning is another environmental issue to contend with. Small wind power utilized in isolated areas and for private homes, businesses and individual is a great way to introduce clean energy on a unit by unit grass roots level. The issue with isolated uses which the instant invention addresses is that isolated uses are isolated by definition. Isolated uses do not carry out the ability to directly power businesses or residential sites over a long stretch of land covering tens, hundreds, thousands or hundreds of thousands of miles providing easy access to direct powering of entities as well as multiple grid interconnection points.
The present invention provides a solution to the problems of the prior art by providing an integrated small wind turbine power infrastructure including small wind energy generating device that can then be easily connected to multiple direct sources or various grid interconnection points. Components of these very small wind turbines, such as the tiny wiring from turbines forming a tiny wiring grid, with wire turbines on the micrometer scale together, have been shown to have superconductive properties which may help increase the energy gathering efficiency of tiny wind turbines, Further, wind energy generating devices on the nano- and micrometer scale up to about an inch may be made with advanced lithography and laser tools and wind energy generating device an eight of an inch long and up can be made via standard molding and forming process. Also, the use of tiny wind turbines allows for deployment of billions of turbines in spaces where larger turbines could not be fit, such as curved guardrails, on top of vehicles and mounted vertically or horizontally in positions that would not be functional for larger turbines. The functions of the tiny turbines would be wide ranging, from generating heat with their energy by affixing them to winter jackets and gloves to rolling out large strips of installable sheets of tiny turbines poor use of public and private highways via median and outside of breakdown lane installations of small wind generating devices offers numerous advantages. First, private highways and municipalities have existing maintenance crew as well as existing relationships with contracted infrastructure building providers who can be trained to install the wind generation systems along specified parts of roadways. Second, the wind power generation systems can be small and noiseless, small enough to fit millions or billions of tiny turbines on a median between opposite sides of a divided highway with existing median. Third, the energy generated by the devices may be distributed directly to homes or businesses along the highway route, such as powering homes or clean power for the electrolysis of hydrogen for filling stations along a highway, either utilizing hydrogen conversion at individual filling stations or at a conveniently located hydrogen conversion plant adjacent to the highway or roadway. Fourth, other clean energy sources such as solar geothermal and other heat conversion technologies may be used to create a multi-source clean energy ‘power grid’ along with or in tandem with the ‘grid’ in place via potential for the connection of miles of wind power gathering, storage and transfer of generated power. Fifth, these infrastructures benefit the wind power generator companies; the roadway owners via lease or easement revenue, any product that could benefit from an easily installed ‘skin’ or sheet of the tiny turbine energy gathering material, as well as provide a stable and consistent infrastructure project generating a service provider economy for clean energy production as well as the environment. Sixth, roadways are a consistent source of wind and by having small wind energy capture generating devices close to the ground the wind energy capture devices, such as small noiseless spiral or helix-style turbines, enable the devices to capture wind energy generated by passing vehicles as well as existing currents. Seventh, the power generated by this system may also be connected to a grid system at many different and convenient points located very close to the existing grid infrastructure.

This method includes the step of generating energy from wind created from passing vehicles using a plurality of ground-based wind energy generation devices, wherein at least about 90% of the ground-based wind energy generating devices are equal to or less than about 25 feet in height and each of substantially all of the ground-based wind energy generating devices is electrically connected to a roadway system electricity grid and positioned on part of a road or near to one or more roads.

These wind turbine generators can employ a turbine rotating around an axis oriented in any direction. For example, in a “horizontal axis turbine,” the turbine rotates around a horizontal axis, which is oriented, typically, more or less parallel to the ground. Furthermore, in a “vertical axis turbine,” the turbine rotates around a vertical axis, which is oriented, typically, more or less perpendicular to the ground.

A description of further example embodiments of the invention follows.
In one embodiment, the axial flux permanent magnet system created by Holmes, Hong & Pullen (“Axial-Flux Permanent Magnet Machines for Micropower Generation” Journal of Microelectromechanical Systems, Vol. 14, No. 1, February 2005, the entire teachings of which are hereby incorporated by reference) is utilized as a means to mount the tiny wind turbines upon, where the wind turbine acts as the ‘energy harvester’ and the three piece sectioned, coin shaped magnet turbines to generate mechanical energy that is passed on through the generator. Similar to solar cell makeup the turbine can lie viewed as a 3-piece cross section with an upper stator made up of magnetic materials with a certain charge, the middle level can be silicon and the bottom level can be made of magnetic materials bearing the opposite charge of the top level. The turning of the turbine excites the opposite charged electrons and creates an electrical charge which can be passed on from the turbine through tiny coiled wires. The instant embodiment suggests a 7.5 mm sized axial flux permanent magnet system size. However, by utilizing the micromachining techniques in the first preferred embodiment the size of the tiny turbine system with the axial flow magnetic system could be scaled down to approximately 200 nm, from the tallest or widest point.
One embodiment of the present provides lines of wind turbines and solar power arrays running along and in the median of major roadways and highways combined with the gathering and distribution of power resulting from vehicle installations of wind and solar energy gathering devices installed permanently or temporarily, for free or for pay, with or without deposit, in use with existing highway systems like FastLane or run as a completely independent program for affixing solar and wind power gathering devices on vehicles to create a widespread portable solar energy gathering networks of vehicles. Vehicles can be affixed with ‘vehicle arrays’ on or adjacent to major roadways and highways potentially creating a solar power gathering network infrastructure of hundreds of thousands of miles long, augmented by millions of vehicles installed with solar arrays designed for vehicles for the purpose of gathering solar power enabling vehicle owners to take advantage of the solar network energy gathering and distribution system to be easily equipped and compensated and for their participation via power gathered by their vehicle system, most of both sets, vehicle and line, of solar arrays will be convenient to the grid and to powering individual homes, public infrastructure and businesses. The present invention also carries with it the potential to move solar power into the double digit overall energy market share in the United States. Additionally, there is a need for an integrated small wind power infrastructure that is easily connected to multiple direct sources or various grid interconnection points. The use of public and private highways via median and outside of breakdown lane installations of small wind generating devices offers numerous advantages. First, private highways and municipalities have existing maintenance crew as well as existing relationships with contracted infrastructure building providers who can be trained to install the wind generation systems along specified parts of roadways. Second, the wind power generation systems can be small and noiseless, small enough to fit on a median between opposite sides of a divided highway with existing median. Third, using a highway or other roadway allows for the installation of many wind generating devices per mile with over 500 wind generating devices possible per mile. Fourth, the energy generated by the devices may be distributed directly to homes or businesses along the highway route, such as powering homes or clean power for the electrolysis of hydrogen for filling stations along a highway, either utilizing hydrogen conversion at individual filling stations or at a conveniently located hydrogen conversion plant adjacent to the highway or roadway. Fifth, other clean energy sources such as solar, geothermal and other heat conversion technologies may be used to create a multi-source clean energy ‘power grid’ along with or in tandem with the ‘grid’ in place via potential for the connection of miles of wind power gathering, storage and transfer of generated power. Sixth, these infrastructures benefit the wind power generator companies; the roadway owners via lease or easement revenue, provide a stable and consistent infrastructure project generating a service provider economy for clean energy production as well as the environment. Seventh, roadways are a consistent source of wind and by having small wind energy capture generating devices close to the ground the wind energy capture devices, such as small noiseless spiral or helix-style turbines, enable the devices to capture wind energy generated by passing vehicles as well as existing currents. Eighth, the power generated by this system may also be connected to a grid system at many different and convenient points located very close to the existing grid infrastucture. This fixed system can be utilized in tandem and complimentary ways to deploy installations, maintenance , billing and depositing of gathered power with the present vehicle system, and solar systems allowing for portable, semi-permanent or permanent wind small wind turbines to be affixed to vehicles at or near the point of entry to major roadways and highways. Vehicle owners may pay little or no charge to have the wind turbine device or devices installed on their vehicles. Deposits from vehicle owners securing the safe return of the wind turbine energy generating system device may be secured through participating vehicle owner's financial institutions or via cash deposit. Participating vehicle owners, turbine installers, roadway owners or municipalities in control of the roadways and the owners of the turbines that are installed may all receive a share of the revenue from energy generated, stored and transferred into the grid or via direct distribution by the system after energy is generated by the individual vehicles and that electricity is off-loaded at designated, easily accessible, vehicle wind system network electricity collection stations or substations. This model creates a situation where drivers of vehicles do not have to spend significant time or financial resources to begin generating wind energy with their vehicles. This model creates a friendly format for wide-scale distribution of wind energy generating devices for thousands of miles of installations on roadways and millions of installations deployed on vehicles to take advantage of. By combining solar and wind power systems within this infrastructure and distribution plan the creation of a complimentary clean energy distribution network is achieved because both wind and solar power systems gather energy under different conditions. By having two gathering systems, if one method is not efficient at a particular time, then the other method may still have conditions that are effective for it to gather energy at that time. Thus the deployment of both sources of energy gathering systems, wind and solar, along this massive infrastructure of roadways enhances the ability to provide a more constant and stable clean power infrastructure.
One embodiment of the invention is a roadway system for energy generation and distributions comprising: a plurality of ground-based wind energy generating devices; one or more roads; and a roadway system electricity grid; wherein each of substantially all of the ground-based wind energy generating devices is electrically connected to the roadway system electricity grid and positioned on part of one of the roads or near to one or more of the roads to thereby allow energy generation from wind created from passing vehicles in addition to energy generation from atmospheric wind.
Typically, each of substantially all of the ground-based wind energy generating devices can be positioned on part of one of the roads or within between about 0 feet and about 100 feet, within between about 0 feet and about 80 feet, or within between about 0 feet and about 60 feet from one or more of the roads. More typically, they can be on part of one of the roads or within between about 0 feet and about 40 feet from one or more of the roads, Preferably, they can be on part of one of the roads or within between about 0 feet and about 25 feet from one or more of the roads. More preferably, they can be on part of one of the roads or within between about 0 feet and about 10 feet from one or more of the roads
The present invention relates to a contiguous or semi contiguous line of interconnected solar panels or thin films combined with a network of wind turbines running for thousands of total miles along public or private roadways. Deployments of energy gathering systems will be both fixed stationary systems as well as mobile systems mounted on vehicles traveling the roadways & highways. By running the solar power gathering network on or adjacent to highways or trafficked roadways the solar power gathering network will have easy access to both grid interconnection and local powering of public and private entities. New advances in solar energy gathering techniques allow for this kind of power gathering line system to be deployed in a more flexible, multiform and cost efficient manner for power generation resulting in the development of a solar energy distributed power network with multi-gigawatt potential which may power entities directly or via interconnection with existing -grid power systems. This roadway solar “line array” deployed in the median, on the side or breakdown lane or as lane dividers creates a system that produces DC current that is then passed through inverter, which converts to AC current and voltage. Power is also fed to the system by a network of vehicles deployed and installed with portable or permanent solar power gathering devices seamlessly mounted to their vehicles and containing linked battery packs that can be stored either in the trunk, inside the vehicle or attached to the exterior of the vehicle, small noiseless to low noise wind turbines to utilizing large stretches of continuous available public and private roadways via easements, leases or the purchase specified rights to create thousands of miles of continuous and semi-contiguous networks of interconnected wind turbine power generation . The wind turbines may be mounted in the median, breakdown lanes or just off of the highway or major roadway. This deployment may run with a complimentary set of installations that uses small noiseless to low noise wind turbines to generate wind power by affixing those wind power generating devices to motor vehicles. Large fleets of motor vehicles driving along available public and private roadways may each be affixed with wind power gathering devices and the energy derived from these devices may be used to power elements of the vehicle directly, or may be used to gain credits for fuel, goods or sold for currency. Rest areas and service stations along with all retail outlets can make these vehicle wind generating systems available for easy purchase and installation for the motor vehicle owner. Power depots where energy is deposited from fixed and vehicle deployments, installation areas and billing systems can be combined to service both fixed and vehicle deployment installations to gain efficiency and save on infrastructure cost
The power generated by the solar and wind energy gathering systems can be used to both connect to a grid or to power homes businesses or systems without connecting to existing grid systems. Power generated and stored in the portable battery system can be transferred into the network power system at Power Depots which can be designed and installed at the same or different points of interconnection and direct distribution as the line array panel outputs. Power is logged by the electricity meters and is either consumed immediately by home or business loads, or is sent out to the general utility grid network. The utility meter spins backwards, or two meters are used to record incoming and outgoing power. The inverter shuts down automatically in case of utility power failure for safety, and reconnects automatically when utility power resumes, Solar power arrays and fixed wind turbines can be situated on a median, breakdown lane or nearby running contiguous with major roadways and offer numerous conveniences such as easy access to the grid, easy maintenance access and direct powering opportunities to homes and businesses with a potential installation footprint of hundreds of thousands of miles of available roadways.
The present invention, in accordance with one embodiment relates to the creation of a massive solar power generating infrastructure system where solar power generating devices are networked together along public and private roads creating the largest contiguous and semi-contiguous solar power generating and distributing system ever built. This specific embodiment envisions nearly continuous solar panel and or thin film and “solar paint” mounted and deployed in the median, breakdown lane and lane dividers and connected or networked together either through a battery pack system or then to one kind of inverter for grid interconnection or another kind of inverter for direct distribution to power users. Using an inverter applies power conditioning to the solar generated power to enable the connection of the solar generated power to the grid system or locally distributed power users depending on the specific type of inverter. There may also be instances where continuous solar ‘strip arrays’ may be connected to a single power source changing unit, or simply tied together in a parallel line connection before being connected to the inverter. Whatever network inverter is used may also need to have an electric meter installed between the power generated by the system to the grid or customer and the inverter. Unlike most solar gathering arrays the implementations of the arrays in this system will be mounted close to the ground, some on the ground, lane dividers or guardrails and rise no more than ten to fifteen feet high to fit into the environmental constraints of highway and roadway deployments and enabling easy access for maintenance crew. These solar ‘strip arrays’ may be connected together in parallel along with a battery back up or backup power system in the event that the grid system fails. The parallel ‘strip array’ systems power deployments and distribution points will be based upon local usage locations and access to grid points.
The ‘strip array’ system may be automated containing switches to feed the grid from the local, strip array, that is networked together via battery system or wired in parallel to pass the electricity to the next closest strip array parallel line or battery storage facility or to local power distribution users based upon need. The effect of hundreds or thousands of miles of this implementation is to form a sub grid of solar, and possibly other, clean power energy sources, where each distribution or interconnection point may be measured with a standard electricity power meter at or near the electricity's point of entry into the grid or direct distribution customer system to gauge accurate electricity usage for billing purposes. In a preferred embodiment solar strip arrays are deployed on a highway system in the median on the ground level, or on top of the median barriers, or on top of other clean power gathering devices in the median such as wind turbines. Solar voltaic paint systems would gather energy from painted lane dividers and solar film would be mounted upon guardrails. These mixed systems would also be used as is most efficient on or around breakdown lanes and on or around toll booth installations. The strip arrays would be networked together and then joined by running a power line in parallel or battery storage and then through an inverted to condition the electricity properly for use in a grid system or via direct distribution. Power lines may be connected directly to sources or buried or flown to appropriate distribution points based upon the physical characteristics of specific implementations as well as private, local, state and federal regulations and specifications. The vehicle solar energy gathering system is made to run in tandem and be complimentary with the ‘line array’ system. With the potential deployment of millions of vehicles whose owners have elected to participate in, and be compensated by, the vehicle solar energy gathering network system creating one of the largest semi-contiguous solar power generating network installation and distributing systems ever built. This specific embodiment envisions millions of solar paneled, thin film and “solar paint” mounted and deployed vehicles installed with these solar energy gathering devices for little or no charge to the vehicle owner. The cost of acquisition of the equipment is borne by the network owners, who work in conjunction, or can be the same party as, various parties who have economic or strategic initiatives to participate in the network including the vehicle installation entity for the network system, the roadway or highway municipality owners and the power distribution and billing depots. The installation systems, billing systems and payment systems described for solar and wind energy herein can be combined into a single unified network. A specific embodiment to incorporate the wind energy gathering infrastructure systems relates to the creation of a massive wind power generating infrastructure system where small, nearly noiseless wind power generating devices are networked together along public and private roads creating the largest contiguous and semi-contiguous wind power generating and distributing system ever built. This specific embodiment envisions five hundred wind turbines per mile mounted in the median and connected or networked together either through a battery pack system or then to one kind of inverter for grid interconnection or another kind of inverter for direct distribution to power users. Using an inverter applies power conditioning to the wind generated power to enable the connection of the wind generated power to the grid system or locally distributed power users depending on the specific type of inverter. There may also be instances where multiple turbines may be connected to a single power source changing unit before being connected to the inverter. Whatever network inverter is used may also need to have a electric meter installed between the power generated by the system to the grid or customer and the inverter. Unlike most wind gathering turbines the turbines in this system will be mounted close to the ground and rise no more than ten feet high to catch wind generated by passing cars and enabling easy access for maintenance crew. Pods of wind turbines will be connected together along with a battery back up or backup power system in the event that the grid system fails. The pod systems will be based upon local usage locations and access to grid points. The pod system may be automated containing switches to feed the grid in the local pod, pass the electricity to the next closest pod or to local power distribution users based upon need. The effect of hundreds or thousands of miles of this implementation is to form a sub grid of wind, and possibly other, clean power energy sources, each distribution or interconnection point may be measured with a standard electricity power meter at or near the electricity's point of entry into the grid or direct distribution customer system to gauge accurate electricity usage for billing purposes. In a preferred embodiment small helix or double helix designed wind turbines are positioned in the median or breakdown lane to take advantage of the wind generated by vehicles as they pass. This kind of wind is known as “dirty” or uneven wind in the wind turbine business, but the helix or double helix style wind turbines are suited to take advantage of this condition to generate power, even when the wind is in cross directions from the wind currents of traffic headed in opposite directions. This condition will cause the helix-style turbine to speed up, while it may hinder the ability of a windmill style turbine to generate energy efficiently. This embodiment also runs in tandem to a complimentary deployment that relates to the creation of a massive wind power generating infrastructure system where small, nearly noiseless wind power generating devices are affixed to vehicles who secure the acquisition of the devices through a special lane, similar to the FastLane designee on a toll road, or local access point to a busy roadway. The portable wind power turbine system pack consists of a small wind turbine and battery charging system. The turbine may be metered to provide charge to an existing car battery or electric car battery or it may be gathered to a separate unit battery, which when a light indicates the battery is full, is then available for drop off for deposit of power into the system electricity depot for a credit against toll costs or for cash credit. The portable wind turbine devices may be installed on the hood, top, sides, rear bumper area or undercarriage of a vehicle using magnets or bracing system that takes as quickly as under 1 minute to install . . . the battery pack may be stored next to the device or in the trunk of the vehicle.
The wind turbines may be propeller, helix, double helix or triple helix style wind turbines. At a wind turbine network distribution or maintenance center the individual vehicle wind system batteries are drained of their gathered power by connection to an inverter and then the vehicle owner or user is credited for the energy that has been gathered, via a credit to that users electronic account, which can be merged with existing FastLane accounts or separately monitored and maintained. Transactions may also be handled on a cash or credit card basis. The electricity processed by the inverter is then distributed back into the grid using one kind of inverter or distributed directly by another kind of inverter. Both distribution methods are measured with meters to effectuate accurate billing. Billing revenue is then shared by the remaining stakeholders i.e. the company owning the devices, the roadway and the installation and power Maintenance Company. There may be more sub-contractors that are compensated in this process. There nay also be fewer compensated parties in the event that one party controls multiple pieces of the system process or in the event that a roadway or public highway is not compensated.
The two systems, wind energy and solar energy gathering systems, can share some or all Power Depot points, maintenance stations and billing systems. Specific energy distribution depots may be designed into the system to store, channel and recondition energy for use in the grid system or to power direct distribution to entities seeking power from the network.
The concept of using roadways as distribution points, fixed solar and wind installations along roadway systems and portable solar and wind energy gathering devices on vehicles and for vehicle owners who do not have to pay to enlist the wind energy gathering devices on their vehicles, where infrastructure to run solar and wind energy gathering and distribution systems via both the fixed installations and vehicle energy gathering systems are easily accessible via roadway distribution points are completely new innovations to the clean energy arena.
The electrical energy of a ground-based energy storage system storing energy generated, for example, from one or more wind energy generating devices, for example, a battery or battery array, can be fed to an inverter and then passed through a power meter as the power generated, for example, by the wind turbine generators is either delivered into a utility grid system, directly distributed to a home or business, or stored for later use, for example, at peak energy demand times, by either larger battery arrays, or via the use of the wind energy to convert to hydrogen and then conversion of the hydrogen back to energy using a hydrogen fuel cell technology for vehicles or grid power usage (See
