Solowheel - Do Want!

Like a stripped-down Segway, Inventist's new Solowheel is geared for the mobile urbanite. Weighing only 20 pounds, the "self-balancing electric unicycle" operates through gyroscopic technology, which a 1000-watt rechargeable lithium-ion battery powers. On a full charge, the Solowheel lasts two hours—but the battery actually recaptures energy when going downhill.

Solowheel will be available March 2011 and will sell for $1,500.
