HapeAria's wind tree and electric car

This fun, educational game is perfect for raising children's awareness of wind power, sustainable forests and reducing our carbon footprint. Use your freewheeling "electric" car to get around and plant trees in the ground! Then, when you're tired, you can go back to your tree and sleep in the hammock. The rotating wind turbine on the tree will generate electricity and charge your electric car while you sleep. Then you can drive the car to plant more trees!
