Harnessing energy from the wind is getting serious, and Arrow Vironoment takes it to the next level with Architectural Wind, a relatively small 6.5-foot, 60-pound turbine it rolled out at Wired's Nextfest last week. It's designed to mount on the top edge of a building, taking advantage of the unique aerodynamics of tall buildings, catching the wind after it's been funneled up the facade.

There's an optional canopy you can mount on the top of the unit as well as the grid you see here that keeps birds out of trouble. Best of all, it only needs a 7mph wind to start cranking out the kilowatts, and it's capable of generating 55kWh per month of clean, effortless energy.
