All you need to add is a wind source, basic tools, and imagination!

Maximum efficiency monocrystalline solar cells.

The Wind to Hydrogen Science Education Kit enables students to invent their own clean energy applications using a small electric motor powered by a fuel cell.

Introduce the Value of Reducing Carbon Footprint.

Power three different solar vehicles — a solar speed boat, an air boat, and a surface submarine — using only the power of the sun. Build three vessels out of your recycled plastic beverage bottles then power them with the sun using the included 1/2 watt, waterproof solar panel. You can build a solar speed boat, an air boat, and a surface submarine. No batteries required.
