Home Energy International in Holland has created the Energy Ball, an egg beater shaped wind turbine. Moving parallel to the wind, it generates less noise than the wind itself. 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. The set has a double gear for light wind and triple for strong, and the base can also be used as a handle. Pre-order for $67.00, which sounds expensive until you realize no fuel costs are involved.
