You know the Joule Thief circuit doesn't actually use RF energy, right?
Joule Thief is not a device, it is a principle of converting any amount of electricity to something meaningful (usually to charge a battery). It could be charge pump or boost converter, even transformer, whatever. F.e. you could use Joule Thief to get 5V from 0.5V of potato battery. Or suck alkaline battery completely dry. Or convert RF from air to something useful. Since we talk about free energy, not about batteries., the latter case is what I told about.
Even self-charging electrolytic capacitor use RF for self-charge. Easily checked with shielding in metal box and emitting more RF energy from generator or even smartphone.
Surely check Searl generator. I'm amased you being into that free energy stuff never heard about it. Even if it is a hoax, the tale and overall concept is very entertaining. There are videos, of Searl himself demonstrating generator on YouTube, many articles and even few scientific papers. Found something about possible Russian replication - http://www.rexresearch.com/roschin/roschin.htm with published paper translation and other stuff. In English
I tested a steel box as Faraday cage with antenna on the cable from RF generator inside. Capacitor clearly show exact dependency of self-charging from incoming RF power. No power - no charge. More power - faster charging to fixed voltage (I took 0.1V as threshold)
My steel box was ~30cm cube. I didn't test different sizes and don't know if it matter.
Joule Thief connected to antenna with diode and capacitor (simpliest detector circuit possible) as power source also show obvious connection between RF power and Joule Thief output. I used classic single transistor generator with two coils on toroid ferrite core as Joule Thief. Had to check charge pump Joule Thief variant too, but was too lazy. :)
