Mariah Power Windspire
Zoning laws often forbid tall wind turbines. The Windspire captures breezes at 30 feet and below with a design in which blades run up a pole’s length and spin around it. Contoured airfoils make the Windspire the first vertical-axis turbine that can start in slow winds without help from a motor or inefficient scoops or wings. $5,000; mariahpower.com
