Default Nanotube Sheets >> Electrostatics ?

Kevin probably already has one of these working in his lab, but this is nevertheless an interesting read:

Hot nanotube sheets produce music on demand - nanotech - 31 October 2008 - New Scientist Tech

The video of the nanotubes being stretched is kinda cool too.

Fascinating. I can honestly say I never expected them to create sound waves through temperature modulation.

Talk about room dependent speakers.

Very cool but looks like it suffers the same LF problems as plasma.

Northwestern University has an entire building just for nano stuff. And 6 professors
doing lots of interesting things with nanotubes and nanoparticles. Can't say much
till the patents are filed. But it is ultra neat...

In theory you could make an electrostatic diaphram out of nanotubes, and be able to
drive it push pull with no more than about 30 volts. And it would be very efficient.
(i.e. loud, very loud)

By the way, since its halloween

That is soooo cool! I knew there must be some useful purpose for nanotubes

Besides very light electrical wiring which is perfect for planes, rockets etc?

Oh crap!!! I'm not worried though since Ray doesn't even know what a CCS is... and he sells tube amps...

Bleh, that stuff is mundane. Thermal transducers is where it's at
