I think we've all experienced laptop thigh burn and there is a definitely a market for designing devices to reduce the heat. However, this invention makes the most of a necessary evil by using the heat to power a wireless mouse.
Instead of having to use a recharging dock, you could just place your mouse on the mousepad; this extends from under the computer, channelling the power of the heat into the mouse. Sounds a bit like a prototype, I know, and, well... it is, but the design has been submitted for the Greener Gadgets Design Competition 2008; if it wins, surely its chances of being made go up?

I spend half my life with a big red blotch on my left leg. Still looking for the perfect laptop cooler-desk-thingie. Too bad this isn't in production yet.
