mini fuel engine to replace batteries

Well, such a thing would be more efficient than batteries, I think, and its energy density would be a lot higher. But nobody would want to inhale the exhaust gasses such a system would inevitably produce, so the near future belongs to fuel cells. There's a short piece about those over at www.dansdata.com

erm... dunno... alternatives are always good.... Not sure if promoting a method that consumes a non-renewanle resource, even if it is in small amounts, is a good thing though...
Perhaps a matrix style device that harnesses the electro-thermo-mechanical-whatnot of the human body would be a cool idea...just imagine, you could attach it to the person asleep next to you. Although i guess it bring a whole knew meaning to the term 'sweat-shop'.The Welsh support two teams when it comes to rugby. Wales of course, and anyone else playing England

Actually, those thermo-thingys are being researched atm, to power mobile devices (mp3 player, mobile phone, pda) in the future - you attach them (or parts of them) to your body, and they generate electricity from your body heat. Sounds pretty cool actually, because they might even cool you down nicely in the summer
This technology taken further would even mean that air conditioning wouldn't consume the immense amounts of power it does now, but PRODUCES electricity through removing energy (warmth) from the air. Now this would be really amazing, and I'd get myself one of these things as soon as I could afford them.
Oh, others are researching machines that produce electricity out of sugar, etc... reminds me of the "Mr. Fusion" from Back To The Future

Batteries also have the advantage of not producing air pollution in their immediate environments. The main pollutant produced by combustion engines is carbon dioxide, which is a greenhouse gas.
"The mini engine produces as much carbon dioxide as one person at rest," or about one 400th the exhaust of an automobile traveling at 60 mph, said Knobloch. One hundred micro engines would produce the same amount of carbon dioxide as one mini engine, he added.
If there's artificial intelligence, there's bound to be some artificial stupidity.

Won't this be aiming at exactly the same spot that small fuel cells are targetted at?DM says: Crunch with Matrox Users@ClimatePrediction.net

I believe Compaq then hinted towards using a similar principle in laptops, where current generated by keypresses would be used...

Several things about that article confused me
The larger version produces about half a watt - is that kinetic or electrical energy? Either way it isn't a particularly useful amount.
Then there was this statement:
The mini engine will run for about two hours on one fluid ounce of fuel, and the micro engine could run for about 67 days on the same amount of fuel, said Aaron Knobloch, a graduate student at Berkeley
Can't really see today's power hungry computing gear going far on that...
