Well, I know things are getting small and all….and nanotubes are getting funding like theres no tomorrow…but really, this is just ridiculous. Berkeley has developed a single nanotube that acts as the antenna, tuner, amplifier, AND demodulator of a radio. It captures signal by mehanical vibration instead of the usual method since its so damn small. Whats very cool is that its got perfectly acceptable quality sound. To demo this, they attached the nanotube onto an electrode. Somehow, through the magic that is carbon nanotube, it transmits the sound as an electric current. There are some awesome pictures and videos of the nanotube in action, along with some audio samplings. Check it out: Nanotube Radio
