Combining solar power with good old fashioned fun, the Solar Powered Wooden Toy Airplane from Switzerland is sure to please even the most fastidious of au naturel parents and renewable energy geeks as well.

Green Diary reports that – unlike so many animated modern toys — this one requires no power source but the sun. Tiny thin-film solar cells provide juice to this little plane’s propeller; the stronger and more direct the sunlight, the faster it spins.

This plane itself is constructed from solid chestnut wood. It comes complete with wheels, wings and tail; there’s even a place for a little wooden pilot to sit. (The figure shown in this photograph is made of beech.)

These and other solar toys are available from Berty and Masha on Etsy. The Solar Powered Wooden Toy Airplane retails for around $106.50, factoring in the current rate of exchange from Swiss francs.
