Wind into the Grid. Günther Hacker

Actually Günther Hacker just intended to buy a small wind turbine for his own home. When this ended up being the wrong purchase, a nearly unbelievable story for Günther Hacker and his friends set in. After three years of flops and strange coincidences they gained success: the first really working small wind turbine for feeding into the grid was born!
People who are interested in small wind turbines that recharges batteries or feed the energy directly into the in-house system will not only find an interesting technological story in words and pictures but also an abundance of information on the right choice for modern small wind turbines, technology for feeding the grid, a suitable location, installation and proper operation.
The technical part is complemented by a test about 25 small wind turbines from Europe, China and the USA being tested in a blast duct and outdoors.
Günther Hacker, teacher by occupation, has quit his former job prematurely to make his hobby of solar and wind energy his profession. His solar-wind-team, which is honoured with four environmental awards, has become famous due to its developments in the area of solar energy and its comprehensive tests of wind turbines for house grid.
