Scavenging Ambient Electromagnetic Energy to Power Small Electronic Devices

Energy cannot be created or destroyed...

If this device is scavenging energy from radio/TV signals, then wouldn't that signal no longer have the strength or distance to provide it's customers with what they are paying for?

If everyone started using these, would our Radio/TV reception suddenly be non-existent as these devices would "steel" the energy away from it's intended targets? Put up a wall of these things between you and your radio/tv tower, and set up your radio behind the wall, and I'll bet you don't get any reception.

I would assume all the broadcast companies will have a fight on their hands as people are steeling their signals, and in the end steeling their electricity.

Good idea, but there is no such thing as free energy, It's still burning coal/nuclear/hydro etc to power the broadcast stations.

Lets turn 1 Megawatt of energy into a few kw, and kill all of our radio/TV in the process.

I think it might be useful for escaped nuclear power plant energy ,To lasso it into a device that can be cooled controlled used or removed would solve a bad situation quickly.I wonder if an old refrigerator could be used as a prototype.Ds

This is nothing new. Joe Tate (associated with the San Francisco Exploratorium) was working with this in the 70's.
