Cool...

Wombat, geothermal would of course not be very practical for your portable mp3 player but I know that players that take their energy from body heat are being researched. The same might work if they take heat from the air, and the energy they use is provided by the room's heating system.

Oh great, so in the future my MP3 player will be parasitic. Why don't they stop pussy-footing around and just have it suck my blood?

I must say I find this idea great: Not only will it have virtually unlimited playtime, but also will it cool me in the summer

Some beamed power research <http://www.dfrc.nasa.gov/Newsroom/Re...eam/index.html>

Probably not really suitable for the office, but an interesting demonstration to be sure.

Well, if you keep the room at the same temperature, and the devices uses the extracted heat (this would imply the devices cools down), it should continue extracting... (one needs to put energy in to keeping the room at the same temperature)

Not possible. The device will never cool down to more than the room temperature.

Speaking of Tesla, it was the Wardencliffe Tower that he was working on for Wireless energy transmission.

And of course here for just general info on Tesla. But of course I bet most of you on here know of Tesla....

We should take lessons from the Flintstones and get sarcastic talking animals to power our machines.

Tesla knew his stuff... it was a shame he destroyed a lot of his research into energy transmission because he feared its use would be perverted.

Some professional pain in the ass accosted me at the home show one year and insisted that one should be able to have wireless surround speakers with amps in them that were also wireless (i.e. no power plug necessary) and why wasn't there a way to do this? I responded that I wished I could accomodate him, because the resulting lightning bolt which would arc across the room would likely fry what little brains he had. (Whew, finally got him to leave.)
