Yugos suck therefore all small cars suck???

If so I would very much like to see it as we have been unable to put up a 5 KW horizontal axis one because new rules here in Cornwall, England prevent you from siting them closer than 50 metres to a hedgerow (because of the bats), which is not suitable on our site.

Soon, a strong storm happened. After that, this turbine was only crap. Good idea but not realistic for long-term-use

I also designed a Vertical Axis Savonius Rotor for battery charging. It uses a 30 degrees wind concentrator over and below the rotor. The author conducted wind tunnel tests on models simulating dams and found a 30 degrees slope increases wind speed by 1.5 times. Since power is cube of velocity,the power gain is 3.34 times. This has its origin from nature in that how is it we experience high winds on a hill top and dams? It is due to height and due to slope.

This Savonius Wind Rotor will be a boon in rural areas.

The vertical wind turbines are really a great approach for roofs of flat city buildings. The noise won´t be a problem at all on higher buildings

Incl mine (rejected in 1992).

There is so much potential to farms of these over the classic horizontal design. These and solar are the wave of the future.

and affordable.

The copy-cats are 50% more expensive and produce less power.

So much of the country side is being ruined by the huge old fashioned turbines.

But how is the sound level, which is a problem for the big turbines. Also, can they be low to the ground?

QUICK QUESTIONS: How much does one cost? How noisy is this product (in decibles).

Thank you!
