- Turbine-less wind generator- how does it work?
- 5 kW wind turbine kit- under $6k in parts, without tower . This appears to be the most affordable package available anywhere for serious wind energy production.
Kite Power
Why not use kites? non-rigid woven fiber structures are very localizable. UAV control systems could be adapted for flight control:

- Saul Griffith on kites as the future of renewable energy
- Academic project assessing feasibility of kite power (link is to a 109 page pdf file). Gives technical details of the mechanism. Estimates 500W from a 2m2 kite if the average wind speed in 8m/s

- WPI Kite Power Wiki - "dedicated to developing a new renewable energy technology - Wind Power from Kites. In this concept, large kites tethered to the ground are used to extract power from the wind. Kites can extract power more economically than wind turbines because they fly at higher heights than turbines can operate."
- Wind driven apparatus for power generation - expired patent for a tethered airborne turbine. This design generates power at the turbine and transmits it to the ground.
Wind Power with Hydraulic Transmission
Back in the golden age of the Dutch, their booming economy was powered by wind in all sorts of incarnations (see article from Low-tech Magazine - Wind powered factories: history (and future) of industrial windmills). Wind provided a lot of energy but one big problem was that this energy had to be used at the time that it occurred, with very little ability to store it for later use. Now in the 21st century, we can use hydraulic implementations to solve this problem. As builders of the GVCS, we are quite familiar with hydraulic systems from projects such as LifeTrac. A hydraulic transmission can also be used for stationary applications and powerd by wind. The "mill" that harvests the wind is coupled to water pumps, generating hydrostatic pressure. With a storage reservoir (water tank at higher level), this energy is available at any time, powering hydraulic motors.
- Patent (granted 2008): "Wind turbine with hydraulic transmission"
