We have to be skeptical with small wind because it’s been so shady up until now, but Mariah Power is seriously poised to release their vertical axis wind turbine this spring for $3,995.

That amount of wind power is roughly 25% of a typical household’s energy.
The Windspire has several features that make it a likely candidate to dazzle the market.
