The Jellyfish wind appliance will launch next year. It is estimated that is will cost the consumer $400 for each unit.
From the website of Clarian Technologies:
The Jellyfish Wind Appliance is a small 36-inch tall vertical-axis wind turbine (VAWT) with a solid-state controller and a variable-speed induction generator that plugs directly into an existing wall socket and automatically generates power whenever the wind blows. The Jellyfish can be mounted on rooftops, wind towers or even existing street light poles - which are already pre-wired to the grid and have the tower already in place!The Jellyfish Wind Appliance has been submitted to the Project 10 to the 100th contest.
