Child Drowning Necklace Alarm Printer Friendly Version
A necklace that needs to be out of water periodically or it sets off an alarm that is installed by the pool. Now that would save some lives. Something colorful that the kids would wear.
You could calibrate it by having the child staying under water as long as they can, then setting that as a maximum time before alarm goes off. Thanks. Please, somebody get rich with this idea for the sake of the kids.
Reward: hearing that the government has made these mandatory for children in pools because they save lives.

Couch Potato Printer Friendly Version
Overweight people all across the country are going home to sit on the couch and watch TV. My idea is to create a stationary bicycle the is attached either to a generator or simply to a device that can measure workload, attach this to your TV so that the TV doesn't work unless you are pedaling.
This will ensure that, for the duration of the show, you aren't sitting on you butt eating Doritos and watching TV all night.
Reward: Tell me what happened after you tried it...How much weight did you lose OR how much less TV did you watch.

Transport Light by Optic Fiber - Save Energy Printer Friendly Version
My idea is to supply light using optic fiber instead of the electric wires to save the energy. As we all know that when electricity travels through wires, it loses its power (potential difference). Hence we lose lots of energy when electricity travels from the power station to our home.
My idea is very simple... here are the steps:
1) Generate laser rays (or other high intensity rays) at the power station and supply it to home via fiber optic. Light loss will be less than 1% in fiber optic.
2) At home, change the laser ray light to normal light using a device.
3) Use any opaque glass material to scatter the light in all directions.
This is my basic idea. There may be theoretical loop holes, but can be corrected.
Reward: :)
