Whether you’re trying to score green tax credits or just help the earth out a bit, the $5000 Windspire is definitely the way to go. Designed by Mariah Power, the Windspire comes with all the equipment you need to start generating power from the wind. Due to the vertical-axis the Windspire uses, people in tighter/urban areas will find it fits into tight space.
Though it seems like a great idea and a way to save the planet, it’s certainly not practical. The Windspire towers 30-foot high and has a 2-foot radius.
