MODERATORS
Isn't this similar to principle behind The Great Seal Bug? I thought we knew blasting RF at a specific receiver can create energy.
Yeah, you can also find "crystal radio" kits
radio receivers that use only the received RF to produce sound (no external power source).
The article talks a lot about their rectifier and im guessing that's where the 'breakthrough' is, but still I feel this is like too many of these articles where its a lot of hype for a little progress.
This is also how passive RFID tags work, the tag harvests just enough energy from the scanning frequency to boot up a microchip and respond with its ID number.
