"Sound Like Thunder"

Just read a pretty sweet article on Nature.com, I guess some Chinese mad scientists have used a sheet of carbon nanotubes (CNT's) as a speaker. They've explained the sheet of CNT's produces sound the same way lightning produces thunder, by heating up the surrounding air, thereby, causing a change in pressure. The thermoacoustic effect these CNT's display apparently produces sound just as well as commercial speakers. Even more awesome, "The nanotube loudspeakers could be strechted to up to twice their original size without breaking and with little change to the intensity of the sound...". The applications these CNT loudspeakers could spawn in the future are mindboggling...can't wait.
Here's a video of an ipod connected to the CNT loudspeaker.
Enjoy the article and the video...
