Magnetic Cars Printer Friendly Version
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.

Speed bumps that don't bump slow drivers Printer Friendly Version
Speed bumps that are filled with water, made of rubber so if you drive slow the water has time to move to other places than under your tires. But if you drive fast you will feel the bump.
Reward: a job and a peanut butter and jelly sandwich.

Motorcycle safety Printer Friendly Version
My idea is to invent a inflatable suit like an air bag for motorcycle riders. Have the rider tethered to the motorcycle, so if the rider starts to fall off it will inflate and the rider will have a greater chance of not breaking as many bones.
Reward: Credit
