Waste Heat to Electricity?

Posted by michael on from the negative-entropy dept.

Darwin_Frog writes: "Recent advances in thermionics at MIT lets waste heat generate electricity, thus pushing entropy one step further down the chain. These devices work at a temperature around 250 deg. C, instead of around 1000, so cars can augment the alternator by using the waste heat in the exhaust system to produce power for onboard electronics and A/C."

  1. Neat Idea, but not terribly useful... by PoiBoy · · Score: 0, Troll

    This is an interesting idea, but I'd bet completely electric cars become more popular within the decade, making these "tack-on" novelties pointless. Oh yeah, FP

  3. Thermionics? Environmentally friendly?! by Astral+Traveller · · Score: -1, Troll
    This article must be a joke. Anyone with the slightest degree of environmental science would know this is bullshit. The story says this technology uses thermionics, chemicals similar to chlorofluorocarbons which have been long known to deteriorate our planet's fragile ozone layer. Putting one of these thermionics devices into every automobile and factory in the country would dissolve the ozone above America in the span of a few years. I, for one, don't want to wear SPF 300 sunblock every time I go outside.

    Of course, there is no way the EPA would allow any project involving thermionics to even get to the planning stage. This story is obviously yet another hoax. I wish the editors would bother to do some research before letting hoax links onto the front page.

    You have some basis (just look at his creative writing post as a reply to the Debian article earlier in the day)!!!!!!
