Small Wind
These people advertise: Energy from wind, generated right where you need it – that’s our SkyWind NG. The first independently tested micro wind turbine is efficient, quiet and Made in Germany.
If you don’t care how much you pay for electricity, and you think small/micro wind turbines are a good look, please jump right in. But by my calculations, you’ll need to live another 100 years, probably closer to 150, to see your investment pay for itself.
After a short period of time on the market in the early 21st Century, small wind has been gone for more than a decade due to a few unavoidable facts:
1) The power from wind is a function of the square of the radius of the blades, and it’s a function of the cube of wind velocity, meaning that the best conditions are high above the ground.
2) To deal with this, manufacturers need to cut costs, making their systems inexpensive and thus prone to maintenance issues. You want something spinning constantly for years, without falling apart, and you want to make it cheap? What the industry learned: Good luck with that.
I can only add that if you think that this is the “first independently tested micro wind turbine,” and that these people are honest, you’re a serious fool.
