Invention of the day: The DC Transformer

[tszaboo]

Good question, if LEDs are just small antennas that transmit radio waves on the frequency of light, than where is the oscillator? 

Electrons precisely falling through the band-gap in the semiconductor material, each producing a photon as they do so?

Everyone knows that light is actually waves and photons is just an a way to explain the Bruguière abstraction.

But indeed there are not many ways to convert a rotation to DC without using any switches, diodes or sliding contacts.

use the motor to drive a peltier junction!  Then hook that peltier up to another peltier then up to another motor!

This is starting to sound like the saga of the wind-powered boat from the Red Green Show.
