Last year we told you about the ultimate in green play, the Solar Wooden Toy Airplane. The wooden airplane toy was crafted by Berty and Masha out of Switzerland and available on Etsy. The toy uses thin-film solar cells located on the top of the plane’s wings to power the propeller.

And now, you can add to your fleet of solar powered toys with the Solar Powered Toy Wooden Helicopter. Berty and Masha are now back at it, having added the helicopter with solar-powered rotor into their array of solar toys Just like the airplane toy, the helicopter is made from solid chestnut wood and features a tiny little pilot in the cockpit, tail fins and even landing skids.

They toy is reminiscent of the wooden toys from olden days, but with the modern twist of using renewable energy as its power source. The best part about it is there are  no batteries and no switches, which makes it super reliable. You’ll never have to scour through the junk drawer or steal batteries from the television remote to play with this toy. All you need is sunlight.

Just like the airplane, the helicopter’s thin-film solar panels use the sun’s energy to power the helicopter’s main rotor. The stronger and more direct the sunlight, the faster it spins. It makes for a cute way to educate your youngster about clean energy, and  sells for around $95, plus a shipping fee to get it to the United States.
