Wind blows horizontal, to date the most efficient wind turbines are the horizontal type designs NOT the vertical or (helix type)shown here. Horiz. turbines have the most sweep area per blade diameter, thus creating the maximum torque at low wind speeds or higher. Helix or vertical wind turbines are the least efficient, in reguards to torque or useable power output! All of these other vertical turbine designs look nice (for show) but are impractical for any kind of sufficient power generation.

your energy bills will not go down if you owned of of these. You might not receive a monthly bill anymore, but you pay a big chunk when you install a turbine, which takes you about 6 – 10 years to recoup. Get used to the fact, that our energy bills will never go down. One of the biggest costs that were never taken in consideration was the price of destroyed eco-balance.

Also, consider insulating your house. I don’t need any power for cooling our house!

if we ever find a way to get rid of 98% of the human consumer – breeder-shitters we will save the eco system

why not a COMBO SOLAR /WIND GENERATOR?

home made wind turbine my friend….. home made…. magnets, wire, bearings.. and some knowledge and effort. makes it cheap

Vertical axis wind turbines (VAWT) are just as efficient as horizontal wind turbines with aerodynamic performance coefficients up to 0.45, investigated by the DOE at Sandia Laboratories. Both horizontal and vertical turbines use aerodynamic lift to propel the turbine, just the rotation is in a different axis. Performance accounts for the torques imposed on the rotor so the sizes of the blades are unjustified. VAWTs are typically quieter, require less material to build and are equally efficient.

Might as well have them seperate. The two wouldn’t fit well together.

I’ve got a few films tackling various issues on wind power…
And please do pass the link around

per annum of course
