The turbine in-a-box

摘要

The developer of an unusual wind turbine thinks his design solves a few wind industry problems. Engineers at Wind Power Cube Inc., Chantilly, Virginia, have designed a modular wind turbine that is self-contained in a square frame. The innovative shape and axle-less design safely generates energy in all wind conditions, says the company. A rotor with nine blades is suspended around the circumference and rotates freely without a center axle or support hub. Power is generated around the circumference, leaving the center open, obstruction free. The wind power cube's circumferential design lets the turbine generate energy almost regardless of wind speed.
