Electricity-Generating Paint

Nanotechnology remains a buzzword that carries a promise (though occasionally a somewhat frightening promise) of great potential. Recent news from a company called Industrial Nanotech, Inc. announced that the company is developing an insulation material that will generate electricity.

The material is literally sprayed on to any surface that is hot, and it absorbs the heat, converting a percentage of it to electricity. As long as there is a difference in temperature between the stuff it's touching and best viagra price the air around it, it will generate power. The most obvious applications, of course, are the inner workings of powerplants and heating pipes. But there's a lot of heat energy lost in a lot of places, so applications could abound (think about your laptop, for example.)

The press release says that "instead of just helping conserve energy (this material) could create energy." But no one should expect that they are going to be able to run their furnace on the energy generated between the heated interior and the cold exterior. No matter how efficient the hydrochlorothiazide viagra material turns out to www.pneumapaniagua.es be, there are always some energy losses in every system. Turning heat into electricity is an inherently inefficient process, because heat is a very low order form of energy, while electricity is very ordered energy.

No specifics are provided about the amount of electricity that might be able to be produced, whether it is watts or only just milliwatts per square foot, so it is difficult to predict how significant this development may be. And even if the productivity of generic viagra without perscription 10 pills this technology is tramadol cod online reasonable, the cost per watt may still be prohibitively expensive. The method of application, however, suggests that installation, at least, will be cheap.

The larger significance lies in widening the expectations for materials to cease to be inert objects and instead to begin to contribute to our needs for energy. Whether this is a better means of turning surfaces into energy collectors than thin-film solar, or some other technology, remains to just try! where buy viagra be seen.

Seriously, there is so much energy floating around that can be recaptured. Coating the back of the fridge, the exhaust stacks for the kitchen exhaust or hot water heater would be great. Roof coatings, lining the levitra free sample inside of a car hood, the applications go on and on. Combined with the also distant paint that incorporates nanotubes and buckeyballs to act as a solar collector, you could deploy some really cool stuff.

Coating the back of the fridge or the hot water heater would *not* be great. Thermocouples have a medium heat conductivity, so they'd tend to keep heat in the refrigerator, forcing it to work harder, but they'd only generate heat from the water heater if its insulation wasn't working.

Thermocouples are limited by the Carnot equation, based on a difference in temperatures. If we assume some moderate thermal conductivity, and relatively thin paint, you can imagine the temperature difference will be minuscule, as will the follow link dose cialis efficiency.

Energy is not created as the article say. Once again an example of bad science in the media.

Law of conservation of wow look it cheap quality viagra energy: Energy can neither be created nor destroyed only altered in form.

Here heat is altered into electricity.

"Here heat is altered into electricity."

Not quite, the temperature difference is turned into electricity. Inhibiting the flow of a heat from a heat pump (like a refrigeration compressor) wouldn't be a good idea. The decreased conductivity would likely only increase the amount of electricity used.

Although, blowing waste heat from another source like a CPU or the exhaust from an engine (without impeding the flow) might actually give a little extra energy.

This could also served as a novel way to make electricity from heat without moving parts: just paint this stuff on the back side of a black object facing the sun for a few extra watts.
