Actually, a company is working on a patent to burn aluminum cans for heat.

They say they will have the product out in the summer of 09, but I've been watching and waiting for a year now, and they used to be saying the fall of 08, and I'm still waiting.
It sounds pretty cool, as an alternate home energy source, even if a few greenies are freaking out because they don't "get it."
But if this works, I say bring it on!
From their website:
START SAVING ALL YOUR ALUMINUM NOW!
You're going to need it.
Forget recycling,,, BURN IT! Create 10 times the financial value out of
your old pop cans over and above what a recycling center would offer you.
Very environmentally friendly and produces no harmful emissions at all!
