Make a green car

I have some idea to make a green car, detail as follow:
1. Body kit and some part of car make by nature material, such as bamboo or wood.
2. Peovide solar cell on top of car, it's not only provide more energy for car but also reduce temperatue inside the car.
3. Replace two mirrows by 2 side camera. It's usefull in narrow parth.
4. The second row can be rotate to make larger space.
5. Provide one big center screen - more than 10", it will sho all information of car.
6. Provide a tablet or computer to control car.
these are some of my idea. I will provide detail later
