Material Converts Radiation Into Electricity

Posted by kdawson on from the don't-irradiate-me-bro dept.

holy_calamity writes "Nuclear powered space probes like Pioneer have 'nuclear batteries' that (very inefficiently) convert heat from decaying isotopes into electricity. US researchers think a new material that converts radiation directly into power instead could make nuclear batteries 20 times more efficient. (Unfortunately they will likely not be user-replaceable.) The material consists of gold, carbon nanotubes, and lithium hydride."

    Is there anything they CAN'T do?

      Just a few things, but those are covered by Lithium, apparently.

    that all these neat technologies depend on exotic materials? Just once I would like some really cool technology to be dependent on something cheaper and easy to obtain, while being ten times more efficient that the gold/lithium irradiated crystals it replaces.

      You think hobo sweat and nail clippings are easy to obtain? Trust me, chasing them and holding them down while you get the supplies is a lot more work than you expect. Unless we set up some sort of hobo farm, I don't see your plan being feasible.

      Sure you would. What do you think we'd do with them after they'd been harvested? Heck, you could have them fight over a grate and some sluices and collect the sweat that way...

    Technically, all batteries "generate" power through a chemical reaction, but I don't want to split "potential" hairs with you ;)
