Shanghai Automotive Industry Corporation has designed the Leaf Car, a special eco-friendly, energy-efficient and emission-free vehicle that features a leaf as its roof, which is the heart of the car.
The roof is made of foliage and produces oxygen like a real leaf. The roof also contains solar panels that generate and store energy from the sunlight. The leafy roof also directs the car where sufficient sunlight is available. The Leaf Car's wheels also generate energy with the help of car's spinning wheels as it moves forward.
