Using Gravitational Waves to Generate Radio Signals

The mechanism is straightforward. Create a uniform magnetic field of the same scale as a gravitational wave and place it in the path of an incoming wave. The subsequent squeezing and shaking of this magnetic field should then generate electromagnetic radiation, just as any other kind of shaking would.

The nanotube radio

The nanotube radio was developed in 2007 by physicist Alex Zettl and his colleagues at the University of California, Berkeley. It is a fully functional, fully integrated radio receiver, orders-of-magnitude smaller than any previous radio. If you’re in disbelief, you can actually listen to the song “Layla” played on the nanotube radio. (Note there’s a significant amount of static noise since it uses none of the external circuitry to filter or process the signal typically found in typical radios).
