Mini Solar-Powered Car
Car is tiny, power source is very large
Solar cars are, unfortunately, still in the research and development phase, although we saw one recently that drove from Texas to New York in 5 days. Despite being impressive, it'll likely be years before we have one sitting in the driveway, charging. Until then this working miniature model will have to keep us entertained.
The world's smallest solar powered car - it zooms along when the sun shines on the solar panel. No batteries - it gets its power just from the sun. No assembly required. Measures a tiny 3.3 x 2.2 x 1.4 cm. When the sun shines on the solar panel, the panel makes electricity that turns the motor and the wheels. A fun demonstration of solar power. Will also work when close to a strong artificial light source. Not for children under 3 years old, due to small parts.
But you can buy it at ThinkGeek.com, this is where we took description from.
