Awesomely cool nanotube radio

An experimental nano-sized radio is so small it reacts directly to radio waves, converting the EM radiation into mechanical energy in one step, with no intermediate steps.

And it really works! The researchers even published a recording of the nano-radio playing Eric Clapton's "Layla." (More on that in a moment.)

Look at the size: It's small enough to fit inside a single cell:



Because it's a proof-of-concept thing, it's rough, but you can hear the actual playback of Layla here: http://tinyurl.com/aqnq76
