Windmill Tech News
Both of these reports were found in the Farm Show magazine, volume 32 No 5.
Windmill in a Box at Retail Stores Soon
A new wind turbine from EarthTronics produces up to 2kW of energy, with only 20 inch blades. The super efficient, ready to go turbine is designed for easy installation and low maintenance. And it's priced to be affordable.
The president of EarthTronics wants to be able to mount it anywhere from a rootop to a pole and generate 20% or more of your home energy needs for about 2 grand.
The turbine is gearless and doesn't need a separate generator. The 6 blades revolved, acting as rotors, with the rim acting as the armature. This means electricity is produced at tip speed, not hub speed, like traditional windmills. They start rotating at 2 mph and reach max output at 15 mph.

Windspire Produces Low-Cost Energy
Windspire from Mariah Power is a 1.2 kW 30' tall, 4' diameter unit that spins in position.
The straight blade Darrieus design was introduced in June of 2008 and can produce 2,000 kW per year at an average windspeed of 12 mph.
It's designed as a self-started, works at low speeds or up to 100 mph winds.
The spire costs 5000 and another 1000 to install.
The company is also designing another, larger spire that will produce twice the energy at 2/3 the wind speed.

A "Wingmill"
Instead of a spinning blade, the Wind Wing is a horizontal blade that pivots up and down on a lever that drives a generator. The wind Wing is parallel to the ground until a breeze blows by.
W2Energy Development Corp says it works like your hand when you hold it out the car window. The wind pushes your hand up or down, depending on the angle you hold your hand.
It's a wing system on a lever 10' from the fulcrum or mount with a balancing weight 1' past the fulcrum. The force needed to move the lever up and down is used to drive the generator to produce electtricity. A sensor will change the direction of the leading adge of the wing as it reaches the top or botoom of the stroke. A weather vane keeps the wing pointed directly into the wind at all times. (the picture looks like bi-plane wings stacked on a pole)
They are projecting it will cost up to 80% less than a traditional propller style windmill.
The company is also working on a Water Wing that will work with river and ocean currents.
