City Windmill Printer Friendly Version
Design a windmill that adjusts to the amount of wind that is blowing. If there is not much wind then not much electricty is going to be produced, but it is still running. Most windmills need 6PMH to start and then max out. As the wind gets stronger the tension should get stronger to produce more power. If the wind is low the tension should release so that a small amount of power is being produced. The actual design of the windmill should not be like a normal one, it should be designed to rotate off of the smallest amount of wind.
Reward: I wouldnt mind my house running off of this.

Search items at home like searching on internet Printer Friendly Version
Its always painful searching things like keys, wallet, cellphone etc. Can we make some chip which is very small and can be attached to it? If we don't find them, open your computer/browser like a Google and enter the name of the item... It should give the exact location where the item is located. That would help reduce a lot of search time daily.

Portable Negative Noise Generator Printer Friendly Version
I'm trying to find out if anyone has invented a portable negative noise generator for in the house. I'd love a small, portable machine that analyzes a noise source and then puts out a negative wave to counter it. We could put them on/in fridges and washing machines and other noisy items in the home to get those annoying sounds out of our lives.
Reward: A calm, peacefull existance.
