Chevrons on Bend in road Printer Friendly Version
In the UK when approaching a bend in the road a chevron sign warns you of the danger ahead. The problem is if you are not familiar with that road the bend could range from almost 180 degrees to just a mild curve. If the chevrons were replaced with a true image of the bend and possibly the angle it would prevent many accidents. The extra cost would be negligible.

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.
