Silent wake up digital Alarm Printer Friendly Version
This idea comes directly from a need that I have. I often want to get up early, before my roomates do, but any "normal" alarm would wake them up as well. I looked for vibrating wristwatches, but for some reason they say it's not for waking people up. (Maybe people would hurt themselves if they rolled onto it.) And it's also hard to make vibrators that small that also has the needed electronics. So, my idea is some variation of a vibrating alarm, for those people who don't want to wake up their roomates (or spouses). There could be a normal alarm clock that sits on a desk nearby. Also, included in the product would be a wrist-band (it can be big, as long as it's comfortable, if neccessary it could be as big as a hand even, as long as it's comfortable to sleep in). At the time that a person wants to wake up, the desk alarm sends a signal to the wrist-band, that vibrates until the person either wakes and turns the desk-alarm off, or hits the snooze on the desk alarm. Ideally, the vibrating wrist-band would be as quiet as possible, but even a little noise, as long as it doesn't wake others up, would be an improvement on what's already out there.
Reward: I'd like one of the final working products for free, so that I can use it. Also, it would be nice if you don't take credit for the idea, but instead, just take credit for making the idea reality and selling/marketing it. Esepcially if it really takes off. Thanks.

Wii Energy Conversion Printer Friendly Version
If you've ever played Wii Sport, you'd know that a lot of kinetic energy is wasted while playing this game. If energy converting devices can be made into the remote (maybe make the whole thing a bit longer to fit the device in), then the remote can convert the kinetic energy into electrical energy. This can be linked to a dry cell holder where the cells can be charged directly from the remote. And this can also be appliable for other Wii games, though those games must involve a lot of movement. Imagine all these while playing Wii!
Reward: Knowing that there are more and more energy converted from thousands (or millions) of Wii players around the world!

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: :)
