peltier device for power generation?

[Christoph]

Would it be either possible or practical to use a reverse peltier device (http://www.peltier-info.com/generators.html) to generate power for something in a computer? I know that it'd give a small output, but there must be some alternative to heating air or water with all that energy.

Maybe you could run a small fan, but imagine the irony: O/C your computer to generate enough heat to power a cooling fan... :)

Just what I was thinking, LOL.
