It works at speeds as slow 4.5 mph while the average turbine needs about twice that to turn. The Energy Balls are sold in 1 and 2 meter versions, for $3,500 and $7,000 (not including installation,) but we would much rather see these dotting the landscape than more nuclear power plants.

Get your kids thinking about alternate energy sources with the Tamiya Loopwing Wind Power Generator Set. The windmill has a loop-wing design with low-friction connectors that needs very little breeze to run. A rechargeable vehicle is included that, after a 5 to 10 minute charge, can run for 1 to 2 minutes.
