Electromagnetic brake Printer Friendly Version
When you press the brake pedal like you normally would, the different current will be sent to electromagnet pads. The electromagnet force will stop the rotating disk. The electromagnet pads are placed close to the disk but will not touch the disk, so they will last forever and the system is simple with fewer parts.

Mag tech engine Printer Friendly Version
This is an engine that uses magnets instead of spark plugs to create the combustion to power the vehicle. It works by placing magnets at the top of the cylinder and on the piston with the opposite polarities to create the down force that spark plugs do. Have the magnet powered by a computer to fire them in the proper sequence to keep the engine running. Let me know what you think. This is as simply as I can explain my concept.
Reward: To have The first 2 cars powered by this technology so I never have to pay for fuel again.

Live-Cam on Aeroplanes Printer Friendly Version
When you're travelling by plane, there's often something spectacular going on outside (and I'm not talking about burning engines - rather something like sunsets, cloud patterns or fantastic sights on the ground). Unfortunately, you can rarely see these things, as you're usually sitting on the wrong side of the plane. So why don't they use a mini camera to broadcast those events to the main screen so everyone can see? It would definitely be a great service appreciated by most passengers.
Reward: Free plane ticket or bonus miles.
