We're not heating anything with CO2. Producing it, yes, heating with it, no. The sun heats the planet and CO2 slows the cooling. Trapping carbon will help cool the planet. Producing electricity with heat will not.

But this idea is gonna be friggin sweet.

]]> <![CDATA[Rough Nano-Wires Hold the Secret to Efficient Heat to Electricity Conversion]]> dammit! I have been trying to think of a way to change heat into electricity for years! Seriously! But with no college degree and no idea what the hell the second paragraph in the article is trying to tell me, it's prolly best that I just wait for these brainiaks to figure it out...

yeah, I said brainiaks

The tech. has been in place for some time to do this and many industrial plants use them on their smoke stacks to recapture electricity.

But I don't believe that you can just use it somewhere it is really hot (like the desert) to make electricity. You need something with a drastic temp drop nearby.

What this discovery has added to the mix is the efficiency to make it worth it to use sources who's temperature diffrence is more slight.

]]> <![CDATA[Rough Nano-Wires Hold the Secret to Efficient Heat to Electricity Conversion]]> Wasn't using human bodies as sources of electricity the premise of "The Matrix"? Boy, howdy, don't life imitate art. How soon until people sell their body heat so others may have electricity? ("As long as you're down here to sell a pint of your blood, how about giving up a few milliwatts for an extra buck?")

]]> <![CDATA[Rough Nano-Wires Hold the Secret to Efficient Heat to Electricity Conversion]]> @mlmmt3: I don´t think that´s correct. If you imagine a room full of highly efficient solar cells or those nanowires and one lightbulb as the only light- / heatsource in it, you would not change the quantity of emmitted light nor the radiant energy, or am I mistaken?

]]> <![CDATA[Rough Nano-Wires Hold the Secret to Efficient Heat to Electricity Conversion]]> @mlmmt3: No. You're right. Couple this with solar panels (unconverted power from solar cells come off as heat), and you get yourself a decent generator.

]]> <![CDATA[Rough Nano-Wires Hold the Secret to Efficient Heat to Electricity Conversion]]> Wait a sec, if this tech really converts heat energy directly into electrical energy, if it can be used on a massive scale, it has the possibility to alter the environment and cool down areas.... Or am I over-thinking this?

mlmmt3

]]> <![CDATA[Rough Nano-Wires Hold the Secret to Efficient Heat to Electricity Conversion]]> Keep in mind that for thermoelectric conversion, you still need a cold sink, somewhere to dump all of that heat you aren't able to convert. Slightly work, and it does mean that simply warming everything up won't actually increase the power available. We still need those ice caps so that we can melt them, intentionally, to provide ourselves with power.

]]> <![CDATA[Rough Nano-Wires Hold the Secret to Efficient Heat to Electricity Conversion]]> Heat in the air is just energy, and the ability to efficiently convert that heat to electricity is a potential panacea. The more we warm the planet with our CO2, the more energy we produce without making CO2. It truly is brilliant. Here's hoping they are succesfull beyond their wildest dreams.

It would be perfect for cell phones and other personal devices that's for sure.

]]> <![CDATA[Rough Nano-Wires Hold the Secret to Efficient Heat to Electricity Conversion]]> Remember the laws of thermodynamics apply. This means, among other things, that the total electrical energy out will be less than the input energy, and the efficiency is governed by the differential temperatures. While this new process might be more efficient than what exists, it cannot beat the laws of thermodynamics, for nothing can.

]]> <![CDATA[Rough Nano-Wires Hold the Secret to Efficient Heat to Electricity Conversion]]> @ALFONZO That's exactly what I was thinking. Although it sounds too good to be true. There have to be some limitations to it.

]]> <![CDATA[Rough Nano-Wires Hold the Secret to Efficient Heat to Electricity Conversion]]> Awesome! Just think: Inefficient electronics give off heat right? (just feel around near your computer) so these things could "mop up" that excess energy and make it useful! and think! the Sahara Desert, instead of being a barren wasteland, would be a barren wasteland positively brimming with energy!
