Just seen this over at Energetic Forum:

Greg has a motor which runs on scavenged energy from radio waves :)
His device isn't optimized (he states so) and he has thoughts on what I deem at this point to be wavetraps. Those wavetraps would bring in power from stations which may be initially swamped by the emissions of a strong local station. In doing so, extra energy may be brought in to the system.
I intend to replicate this, or at least follow the theory in a build - thinking along the lines of a smaller, faster spinning motor.
The use - to perform any work normally obtained from Mendocino or other low torque motors. This would, feasibly include AA battery charging, capacitor charging.
Ideas include:
It could form a usable free source for a fishtank oxygenator.
Be used as a valve control, with variable timing like a mechanical oscillator.
Could be built elegantly and used as a garden ornament feature.
There are ceiling fan possibilities for something highly tuned.
Even as a curio, a batteryless motor.
It would also further own experiments into household EM radiation reductions, which I believe to be far too high around us and in need of being reduced.
Taking such a project further, would include designing circuits for other frequency bandwidths....FM, microwave etc.
