Atomic MEMS Battery has 50 Year Charge

Posted by michael on from the keeps-going-and-going dept.

notestein writes "Working for DARPA, a couple of Cornell researchers (Amil Lal, Hui Li ) have developed a battery that uses decaying nickel-63 to drive a flexing MEMS cantilever to generate electricity. They expect a production version to produce useful energy for at least 50 years."

    Uh, I don't think you'll be keeping that laptop for 50 years. Seal that in.

    The latest pentium laptop will still only get 2 hours use out of it.

    That's a good point. They'd better not call it "Atomic" They should call it "nano"-- we haven't yet breed a fervent religious movement that hates nanotechnology for defying god, etc. Those types are still stuck on outlawing human cloning ( which is a right, by the way, you the right to reproduce-- who has the right to tell you *how* to reprorduce? Nobody)--- now that they have finally gotten over test tube babies.

    I know I'd never keep a laptop for 50 years, but I might keep one for 5 years. I'd be happy to have a 5 year battery. Or a flashlight, or a radio, etc. 50 years is an unintentional side effect. Besides, if they use some sort of standard cells, I can just transfer them to whatever device I end up using down the line. That would make it worth the high premium for something like this.
