I have this idea of creating a car which is ecologically friendly. I have this idea of creating a car that runs with the help of electric magnets. The ring pistons are made up of magnets which will be connected to the came shaft, but instead of having valves for fuel injection, we can use an electric magnet which when provided electricity will provide enough magnetism to push the piston down as they will be of same polarity. This will result in the spinning of the cam shaft and thus the car will move. We can also connect a generator with wheels instead of a cam shaft that the faster the car runs the more electricity it will provide to charge the battery.
Reward: Be known for the idea.
