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.
With the current fuel crisis forcing people into smaller and smaller vehicles and spelling impending doom for society as we know it... we figured it was a perfect time to offer these Thumb-Size R/C Mini Coopers. Their all-electric engines run off of button type batteries and are very fuel efficient. Hey... they can't carry much groceries in the trunk, but they do feature full control with forward/reverse and right/left turning... plus the remote looks like a tiny cellphone. Take that high gas prices!
