Using clean energy sources such as the wind and sun are becoming more and more important to the sustainable future of our planet. This mini wind turbine is a replica of an actual wind powered generator (scale 1:250). Itís three blades rotate silently at a soothing 18 revolutions per minute. With pollution and global warming being a major worldwide problem it is increasingly vital that we explore, learn and teach about renewable energy sources. This wind turbine is powered by the sun in keeping with an environmentally friendly line of thought. The turbine stands about 26cm high.

1 solar powered mini wind turbine (easy assembly, no tools required), instructions. All in a plain, sturdy brown box.
The solar panel converts sunlight into electrical energy which flows from the panel in the base of the plastic turbine to the top via hidden wiring in the column. The electrical energy then flows into the small electric motor hidden by the motor shell where it is converted to movement energy, causing the blades to turn. Now you can feel the wind energy being generated from the moving blades. If it is an overcast day and there is not enough sunlight to power the turbine a strong spotlight can be used as an alternative.
