Off Peak Power Printer Friendly Version
Usually power companies have lower rates during a certain time of day, why not have a home device that charges up during off peak hours, then the home uses that electricity during peak hours. Maybe as simple as a rack of car batteries, or a flywheel or large capacitor.
Reward: We all get one, and fewer polluting power plants are built.

Electric Back Scratcher Printer Friendly Version
For many years I have hoped someone would create a Portable Electric Back Scratcher. I have imagined it would look something like a small floor lamp stand that would have a timer on it and would have adjustable height and size for the area of your back, and it would comfortably scratch my back until I fell to sleep. How relaxing this would be. No need for sleeping pills. What do you all have to say about this one?
Reward: My Reward: send me one of the first of the finished product.

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!
