Not everything that is potentially toxic is bad. Thats why orgs like Greenpeace drive me F'ing crazy! They focus on all the little BS stuff, instead of prioritizing environmental problems. The EPA does the same crap. They'll let a huge oil refinery spew out such pollution that people in those towns actually have OPEN SORES ON THEIR SKIN, but then they will kill a renewable energy project because it could harm the environment of some rare fresh-water clam or something!

But a large-scale efficient thermoelectric device could just cut out all the middle processes at a power-plant, and convert the heat from fuel directly into electricity, kind of like a fuel cell, but able to use any burnable fuel (or nuclear, or solar, etc). Neat.

Anyone remember the nuclear thermoelectric generators they used on the moon during Apollo? The astronauts had to hand load the plutonium rods into them, once they got to the moon. I guess a space suit makes a fair-to-middlin' radiation suit. :-)]]>Jul 25th 2008 1:32PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/
For those of you who don't know, a combined cycle plant is essentially a large turbine (like a jet engine), fired by natural gas or oil usually.

The combined part comes from using the waste heat generated by the turbine to generate steam and spin a generator.

I've always wondered if you go a step further and use the exhaust pressure to spin another generator, like how a turbo works.]]>Jul 25th 2008 1:39PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Can't do that; the turbine converts pressure drop to power; in a powerplant, it's designed to take the pressure down as far as possible. You can't piggyback another turbine on the back, because you're already at or near condensation. (Three-cycle plants are possible, of course, using a gas cycle, then either a steam or gas cycle, and finally a steam cycle, but you have to have the full loop using a heat exchanger to get the heat out of the turbine exhaust, not using the pressure.)

In an ICE, of course, the exhaust is at little risk of condensing, because it's mainly air, not steam (i.e. it's a gas cycle), and it exits at high pressure; so sticking a turbine on makes sense.]]>Jul 25th 2008 5:18PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Ideally, an ICE uses the oxygen in air to bind hydrogen and carbon in lower energy states producing carbon dioxide and water. The nitrogen is passed through and not altered so long as the combustion temperatures are kept low. ICE exhaust most certainly contains steam.]]>Jul 28th 2008 11:27AMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/;) really.]]>Jul 25th 2008 1:31PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Jul 25th 2008 1:58PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Jul 25th 2008 2:04PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Jul 25th 2008 3:22PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Jul 25th 2008 5:18PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Jul 25th 2008 8:54PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Jul 26th 2008 3:02PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Jul 25th 2008 1:35PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Jul 25th 2008 1:47PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Jul 25th 2008 1:54PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Jul 25th 2008 1:56PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Jul 25th 2008 4:05PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Jul 28th 2008 11:14AMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Jul 26th 2008 2:27AMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/
Nothing is clean when MANUFACTURED, no one mentioned manufacturing. What would be clean is the energy produced by not burning fuels to produce power in the first place. And if these researchers suggest using it in automobiles (mere feet away from humans), I can`t see why it would be dangerous to bury coated rods a few kilometres undergound. ]]>Jul 25th 2008 2:03PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/Jul 25th 2008 2:28PMhttp://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/http://www.engadget.com/2008/07/25/another-team-figures-out-how-to-convert-waste-heat-into-energy/
