Radio Frequency (RF waves) ARE the same energy as the electro-magnetic energy that created them ! (Different frequency, of course). RF waves are CREATED from electricity in the microwave “horn” or airport tower radar transmitter or airplane radio transmitter or CB radio or commercial radio transmission tower and transmitter or cell phone transmitter. The only difference is in the amount of energy transmitted.
ALL of these transmitters have (significant) losses changing the input electrical power into RF energy. (Try running your cell phone for a few days without recharging it: the total energy in your cell phone is ALL the energy available in the device: If you hook up that cell phone battery to a 120 volt inverter/converter and plug in your microwave and refrigerator, you can heat your lunch and serve your buddies a cold six pack. For a short time, at least.)
You can't even do that because the battery's internal resistance would keep the current down to a level where the big appliances just wouldn't work.
>> You can say it is the same theory but RF waves and electricity are not the same.

I didn’t say that - it was part of a post a post that I quoted. But I believe the gentleman’s point was that the electromagnetic radiation for the separation of elements is different than passing an electric current through a substance.
