The 75021 Loopwing Wind Power Generator by Tamiya lets you explore the mechanisms involved in harnessing the alternative energy of wind power.
The windmill features loop-wing design that can be rotated by the slightest breeze. You can also run while holding it to generate wind artificially. The kit comes with a rechargeable vehicle that uses power generated by the windmill, running for 1-2 minutes for each 5-10 minute of charge.
Special "loop wing" design secures high efficiency in power generation, by ensuring that even a minimum amount of wind will produce quick rotation of windmill.
2 types of gears allow choice of double gear for light wind, and triple gear for stong wind, improving power generated by motor depending on wind strength.
Base doubles as handle allowing you to run while holding windmill to generate power.
Low-friction connectors to ensure smooth rotation by wind & efficient power generation.
