Tesla was interested in this, eh? I did this sort of thing in 1967 when I put a capacitor on the output of my crystal set, and was able to (very weakly) light a standard panel lamp. Nothing is new, only the details change.....
- chockablock 13y agoUnwarranted grumpiness. Harvesting power from radio transmisssion is indeed not new. What they demonstrate, however, is transmission from the 'receiver' to additional devices by modulating how much power is absorbed or reflected. This is fundamentally different from just using the harvested power to run a second transmitter, because modulating backscatter is 'orders of magnitude' more efficient.
