- Utilization of Wind Energy at High Altitude - Alexander Bolonkin - V.P. of Consulting and Research Co., NY, USA – Abstract - Ground based, wind energy extraction systems have reached their maximum capability. The limitations of current designs are: wind instability, high cost of installations, and small power output of a single unit. The wind energy industry needs of revolutionary ideas to increase the capabilities of wind installations. This article suggests a revolutionary innovation which produces a dramatic increase in power per unit and is independent of prevailing weather and at a lower cost per unit of energy extracted. The main innovation consists of large free-flying air rotors positioned at high altitude for power and air stream stability, and an energy cable transmission system between the air rotor and a ground based electric generator. The air rotor system flies at high altitude up to 14 km. A stability and control is provided and systems enable the changing of altitude. Read the full 2007 report here (PDF)

- The Kite Generator: a Breakthrough in Wind Energy? - Aug 2005, ASPO Italia - Wind energy is free and abundant, but we continue to have problems harnessing it efficiently. A possible way to overcome some of the problems would be to get rid of the wind tower altogether and use aerodynamic lift to position the wind collecting unit high in the sky. In other words, to use kites. This idea has been already proposed in various forms, but recently Massimo Ippolito of Sequoia Automation S.p.a. has developed a simple and elegant concept that promises abundant energy at rock bottom costs: the kite wind generator (KiteGen).

- Small Wind Energy Technology Breakthrough - A new technology for small wind turbines has just been introduced by Southwest Windpower Inc of Flagstaff, Arizona. Called the AIR-X, this compact 400-watt wind turbine is designed to use the energy in the wind to charge batteries that provide electricity for remote homes, water pumping, telecom transmitters and sailboats. Although wind generators have been around for nearly a century, the company claims this new technology reduces the size and allows them to operate much quieter than previous designs. The AIR-X has incorporated a microprocessor, previously only found in today's state-of-the-art Megawatt sized wind turbines, to improve performance while allowing it to operate quietly - read more from this press release from Southwest Windpower @ Renewable Energy Access

- Digital Gas, Inc. signed an agreement with International Trade and Technology Centre Ltd. of Dublin, Ireland which gives Digital Electric the exclusive right to manufacture and market a breakthrough wind energy technology that is anticipated to deliver a return on investment that is significantly greater than conventional wind power generation systems. The new wind energy systems will result in approximately 35% greater power output at 10% less cost per unit, according to the company. These efficiencies in capturing wind energy are created by using a series of self-adjusting multiple hydraulic pumps and multiple variable speed generators. By transmitting power from the wind blades hydraulically to turbine generators located at ground level, the cost of maintenance is dramatically reduced.

- Low Wind Speed Technology Phase II: Breakthrough in Power Electronics from Silicon Carbide - Peregrine Power LLC - Project Description: All commonly used power semiconductors in power converters today are based on standard silicon technology. These have numerous limitations that power electronics designers work around. Newer designs in wind turbine drive trains will increasingly depend on such power converters to allow full power conversion and variable speed. Silicon carbide (SiC) has much better performance characteristics, including: Lower resistance and conduction losses, Faster and cleaner turn-on and turn-off characteristics that result in much lower switching losses, Much higher dielectric constant which permits higher voltage applications, Much higher thermal conductivity, Much higher operating temperatures, Much greater ruggedness and reliability, Positive feedback as to resistance which automatically causes current to be shared well among parallel SiC dies to achieve higher currents. This project will perform baseline characterization of SiC chips to determine their operating characteristics. Based on these data, some preliminary designs and cost estimates will be developed to determine SiC’s potential impact on wind turbine power converter designs, efficiency, and operating costs.
