I never said it was sucking the heat out of you.

Maybe It would makes more sense if I had said "excess body heat". Sucking the body heat from you is absurd.

In my first post I was implying that there is a First Law of Thermal Dynamics, albeit subtly. By that logic, a sweater that "sucks" energy from your body would me illogical to make because it would use just as much energy (and usually then some) to suck the heat from your body as your body makes.

That's why electric companies don't conserve the extra energy they make. It takes more energy to conserve it than to just let it pass through the power lines as heat.

RinjiHalfElf, no its just using the heat that your body makes, it's not "sucking" it out of your body, like some kind of a parasite.

I would imagine that the only time we would want our body heat converted to energy is if we are hot.

Remember, when the solarsweater gets energy from your body heat you are also losing your body heat because the solar sweater is converting it to energy. That just defeats the purpose of a sweater.

"Everything that's warm gives off some heat."

After reading a line such as that, I have trouble taking the rest of the article seriously.

I don't get how it would be able to send the infrared energy it recieves to something like a battery if these nano-plastic cells are spray on, no wires at all. Then if wires were needed, then wouldn't that get rid of the whole cost effective point? ?? ??

The sweater made me think, what if all of our clothes had something like that to harness body heat? And just think of things like blankets! The electricity we could make! Plug your clothes in at night to let them drain the electricity into your house! Or... we could just do some other stuff that would be a whole heck of a lot easier and cost effective...

I think if everyone just coated their roofs in this.... may not be able to completely support a household's energy needs, but I'd immagine it would reduce energy costs.

the oil companys have a ton of power here, but were not the only country in the world. for instance, china is a very poluted country, and recently the government has been growing a bit more ashamed of how it's environment looks to the rest of the world. so they are attempting to creat new ways of cleaning up. The government is passing a law reqiuering very strict hi fule mileage laws. and you may think "yeah but the car companys are in the oilcompanys pockets" well I tell you that the oil companyes will never have enough money to subsidise what the car companeys can make by selling cars to 3 billion chinese. the world isn't perfect, and were still hurting it. but things are changeing, slowly. and I wouldn't be suprised if in 10 years solar power is a comman thing. especially in a free market society, because in the long run solar energy will be far far cheeper, we are bound to get there eventualy, unless this whole nuclear fusion thing works out soon, which it wont.

Just think. If they started painting every single public building and every new building with this stuff, you would be able to harness so much solar energy, plus this stuff has to be more efficient because it contours to the surface that it is covering! Amazing!!!

I agree with psycopyro, the oil companies have alot more people and politicians in their pocket than most people think, they have a lot of pull over what car companies make hybrid cars, and with a few "contributions" here and there they keep most from putting more out. I would love to be able to live with useing the power of the sun for everything and hope that the right people get in power in the right places and this will happen sooner than later.

I wouldn't quite say oil companies are too powerful. After all, there are hybrid cars available and if one had enough personal incentive and initiative to buy one, it would serve to weaken the companies' hold over the market.

Oil won't run out in my lifetime, but I'll live long enough (I hope) to see more environmentally safe energy sources implemented into the mainstream. What a great article.
