World’s Smallest Solar Car
This tiny solar “racing” car, the smallest one in the world with its 33 x 22 x 14 mm in size, requires no batteries whatsoever. You only need to take it out in the sunlight or close to a strong artificial light source to get the wheels moving.
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.
The World’s Smallest Solar Racing Car is available over at the ecotopia.co.uk website for £11.99 (about $23 USD).
