yes its true physicists in the United States have developed a device which they claim can turn heat in to sound then in to electricity.they are trying to make them repalce solar cells and make available to market in 2 years which can be used in labtops to use heat and cool them by utilizing electricity produced by it.they are planing to use them in micromachines also.

Thank god we have got another renuable source of energy from the waste

intresting, how do they harness the sound or heat. it would have to be alot of either to make a difference

It would be more interesting if you had a link to your source, but since I am a kind person here is a link to that very article http://www.unews.utah.edu/p/?r=053007-1.

But it is interesting that they found another way to produce energery and of course they just produced another weapon for military's around the world to test out to be against other people. What do you know the U.S army is funded it with this wonderful excuse.



Now the questions that come to mind is what kind of heat needs to be generate or order for this to be produce? Of course that simply got answer through the heat of the sun which is good because we don't have to produce our own heat for this to work. Interesting enough they this device will be able to cool down computers as well, which I wouldn't mind seeing because then people won't need these extreme cooling systems after overclocking them to 250 degree's.
