Patent MarketPlace: Wind Power, Solar Power and Other Energy Patents

Energy Efficient, High-Torque Electric Motor (Morris): U.S. Patent No. 10,199,914 plus CIP

Electric vehicle manufacturers are doing everything possible to increase the range their vehicles can go on a charge. In addition to increasing battery capacity, the other strategy to accomplish this is to use electric motors that are more efficient. This intriguing patent addresses exactly that. In fact, it is the first new concept in electric motors in decades!

This patented electronic motor features a shaft that has a larger diameter and shortened length. It essentially “pancakes” the motor. It is a high-torque motor that operates more efficiently by taking advantage of repelling and attracting forces from magnetic fields. It uses lifting electromagnets for improved efficiency, and it includes a fail-safe feature that enables the motor to continue to operate even when some components fail! The inventor has developed a working prototype that can be viewed by any parties interested in the portfolio.

U.S. Patent No. 10,199,914 for “Closed loop leveraging electromagnetic motor” has applications in electric vehicles as well as any products currently using electric motors – such as water pumping stations plus construction and agricultural equipment – where increased efficiency is needed. The granted U.S. Patent comes with a Continuation-in-Part Application that enables the motor to use an app to control and monitor the motor’s parameters. This portfolio would be a critical acquisition for any electric vehicle company or manufacturer of equipment that use electric motors!

Higher Capacity, Rechargeable Lithium-Air Battery (Miles): U.S. Patent No. 8,795,868

The most significant limitation for electric vehicles is range. Most cannot go as far on a charge as a gasoline-powered car can go on a tank of gas, and charging stations are not nearly as common as gas stations. The next major technological challenge facing electric vehicle manufacturers is improved range, and that means a new generation of lithium batteries that can hold a greater charge. This patent addresses exactly that need!

In a typical lithium-ion battery, lithium ions transfer from the metallic lithium component of the anode electrode into an electrolyte leaving an electron behind, and the lithium ions circulate as positive ions in the electrolyte, replacing the lithium ions consumed at the lithium-ion battery cathode. In next-generation lithium-air batteries, oxygen is passed through the pores in the cathode and introduced into the electrolyte. These negative oxygen ions combine with the lithium ions to produce lithium peroxide and/or lithium oxide. The electrical charges produced by these reactions pass externally between the electrodes to provide external electrical current.

The only way to increase the power stored in a lithium battery – and thereby enable electric vehicles to go as far on a charge as gasoline-powered autos can go on a fill-up – is to switch to a molten-nitrate-salt electrolyte battery in which the electrolyte is heated above its melting point to become an ionically conductive liquid containing lithium ions and nitrate ions. A lithium anode and cathode are immersed in the electrolyte, and the nitrate ions in the electrolyte become an internal source of oxygen when the electrolyte is heated to above its melting point. The anode and cathode are connected to the conductive surface, and electrical current flows through the battery as a result of the electrochemical reactions in the electrolyte, outputting substantially more electric current than current-generation lithium batteries.

U.S. Patent No. 8,795,868 for a “Rechargeable lithium-air and other lithium-based batteries using molten nitrates” is a robust patent with 19 Claims. It would be a critical acquisition by any battery OEM or electric vehicle manufacturer that is seeking to produce higher-capacity lithium-air batteries.

Electric Power Virtually Anywhere (Riley): U.S. Patent No. 9,825,583

Solar panel farms and roof-mounted solar panels are an increasingly common site across the U.S. Wouldn’t it be incredibly convenient if you could set up solar panels when and where you needed them for power? Thanks to this invention, you can. This patent introduces a portable solar panel system. Thin-film solar panels come in a roll, and they are simply rolled out onto the ground or on the surface of a body of water (they float). The invention includes a power inverter so the system can be adapted to produce 120 volts of AC current or whatever power is required by the user.

The solar panels can be laid out on the ground or on the surface of a lake, pond or other body of water – even the ocean – and they begin to produce power in minutes. The technology is totally scalable – add as many panels as are needed to produce the electric current that is required. Smaller sets of panels that are easier to transport can be linked together to produce whatever level of electric power is needed. The portable solar power system covered by this patent has multiple applications:

The acquirer of U.S. Patent No. 9,825,583 for a “Portable solar energy system” will own technology that will create an entirely new business segment in both the solar power sector and the portable power industry!

Hydro-Electric Energy Storage (Aaltonen): U.S. Patent No. 8,274,168 plus European Patent Application

Many electric utilities own a large lake (Candlewood Lake built by Connecticut Light and Power in 1926 is a good example) into which they pump water at night – when demand is low – and run water out during the day – when demand is high – through turbines to produce electric power. These lakes are essentially batteries that efficiently and cost-effectively store huge amounts of electric power. But what does an electric utility do if it did not buy a huge tract of land 100 years ago when land was cheap?

U.S. Patent No. 8,274,168 for “Generating hydroenergy” addresses exactly that issue. The invention covered by this patent uses an existing body of water – a lake or reservoir – to store excess electric power and retrieve that power when needed. This technology applies to any electric utility, but it is especially useful for the storage of excess power from offshore wind farms. In addition to the U.S. Patent, there is a European Patent Application, so the company that acquires this patent will be able to build highly efficient and environmentally safe electric energy storage systems for electric utilities across the U.S. and Europe.

Improved Air Flow Magnus Wind Turbine (Kheirandish): U.S. Patent No. 9,273,666

More and more of the electricity we use is green, and wind power is a growing sector. In fact, wind turbines have become a common sight on both land and at sea. The challenge with any electrical generation system – be it fossil fuel or renewable – is to make the system more efficient, and that is what the invention covered by this patent does. Magnus wind turbines do not use the propeller-type blades on conventional wind turbines, but use rotary shafts that transfer torque to a generating mechanism. They are called “Magnus” turbines because they work on what is known as the “Magnus effect” – the sideways thrust on a rotating cylinder placed with its axis perpendicular to a current of air.

Just as the earliest wind mills had large flat blades that were replaced over time with the narrow blades used on the conventional wind turbines of today, the shape of the rotary shafts on Magnus turbines has changed over time. This patent covers an invention in which an air-flow-directing plane directs airflow to the low-pressure area, causing a delay and an increase in Magnus lift. Additionally, the crossed spiral on the surface of the turbine’s cylinder provides more airflow in three directions upon the rotary cylinder, and this produces yet more Magnus force.

U.S. Patent No. 9,273,666 for a “Magnus-type wind power generator” would be an excellent acquisition for any business that manufactures generators, both fossil fuel-powered units and wind turbines. This invention will give its owner the opportunity to leapfrog the technology of all of its competitors and offer a next-generation, more efficient electric-power-generating unit.

Lower-Cost Photovoltaic Cell Manufacture (Schwartz): U.S. Patent No. 8,618,411

Solar power has taken off, and solar panel farms and solar panels on rooftops are becoming common sights around the world. As solar companies try to reduce costs, one area of potential cost reduction is to make the manufacturing of the photovoltaic (PV) cells that constitute the solar panels more efficient and less expensive. This is exactly what the invention covered by this patent does! PV cells are currently manufactured upside-down starting with the glass front and ending with the metal back. This Patent turns the process right-side-up so metal foil roll-fed production is possible. The significant reduction in manufacturing cost will make U.S. PV cell OEMs competitive with Asian manufacturers!

U.S. Patent No. 8,618,411 for a "Method of making photovoltaic cell" would be a critical acquisition for any business in the solar power industry. Manufacturers would use the technology directly, while solar panel installers would license it back to their solar panel suppliers.

Wind/Solar Generator (White): U.S. Patent No. 8,269,368

This patent takes both wind and solar power-generation to the next technology. The invention covered by this patent starts with a totally new concept in wind power generation. A conical vortex moves air through the unit with as little interference as possible, reducing heat and improving efficiency. The cowl-housed design addresses many of the problems with the wind turbines of today – height requirements, whoosh noise, bird kills, high maintenance costs, downtime for maintenance, high-wind and low-wind downtime, and limited access to transmission lines – to name just a few. Solar panels provide power when wind speed is too low or too high. In addition, the technology is totally scalable, so units can be manufactured in various sizes and generation capacities.

U.S. Patent No. 8,269,368 for a "Wind and solar electric generator" would be a critical asset for any wind turbine OEM, or any business looking to break into the wind power sector.

Swivel Solar Tracking Device (Moore): U.S. Patent No. 9,182,153 and PTO Application

The invention covered by this patent describes a swivel tracking device that orients solar panels or arrays toward the sun throughout the daylight hours to harness the maximum amount of energy. This single device enhances the output efficiency of solar panels by 20% to 40% as compared to fixed solar panels, an improvement that other trackers require two mechanisms to achieve. This patent provides these key advantages:

The growing popularity of solar power as an alternative to – or supplement for – fossil fuels has led to significant growth in this sector. The solar panels themselves are a mature technology, so the focus is now on optimizing the power generated by solar panels. The swivel-positioning device provides a means of adding an additional dimension to power-generation optimization. The acquirer of U.S. Patent No. 9,182,153 for a “Ball bearing tracker assembly “ will have a unique strategic competitive advantage over its competitors.

Zero-Contact Transmission for Wind Generators (Future Force): International Portfolio of Five Wind Power Patents

While renewable power such as wind is low cost, a substantial amount of the energy generated by the wind turbine’s blades is lost to heat and friction in the transfer of power to the electric-generation unit. This international portfolio covers a transmission that uses magnets to dramatically reduce friction and, thereby, also reduce energy loss in the system’s drive chain. The Zero-Contact Transmission covered by this Patent has its most obvious applications in wind power, but it also has applications in any power-generation system that is based on mechanical energy such as hydropower, tidal and wave power, and fossil fuel and trash-burning plants.
