Commercial flight guidance Printer Friendly Version
How about a device that could take control of a airliner like a heat seeking or guided missile. In the event of a hijacking military jets could be deployed taking control of the jet and forcing it to land safely, brake and shut down.
Reward: no more 9/11

Magnetic transport Printer Friendly Version
Like magnetic poles repel each other, right?. What if we were to have pavements or "magnetic ways" that were the same magnetic pole as a magnetic skateboard. People will be able to hover and move by leaning forward and stop by leaning backwards.
No fuel or energy is consumed either. Surely we could use this concept for motor vehicles on highways?
Reward: I would like to be involved in the R&D if someone were to do this.

Portable Shopping Cart Printer Friendly Version
Wouldn't it be nice if someone could produce a Portable Shopping Cart on the lines of a Twin Stroller. As a parent I sometimes find it frustrating loading the kids into the car and unloading the cart, then having to leave the cart at your parking spot, which is a big pet peeve of mine. It is also hard to find a cart that has a dry kid seat when it is raining.
Reward: portable shopping cart or new twin stroller
