Most likely yes. It seems related to how rfid works and a little know surveillance devi e invented in the 50s that used a wireless mic without power that turned on and transmitted when excited by a transceiver. They were very hard to detect. We used them against the russians:)
So the theory might be similar. Something inside it is excited by rf and generates a current. Not much current …might be kickstarter vaporware.
While energy harvesting technically works, the quantity of captured energy is amazingly low. On the order of what those small solar cells in a calculator can deliver.
This equatesto months to charge a single aaa battery.
Too little current to really charge your cell phone or anything else for that matter. Never ever happen in real life.
Yes it’s possible and will likely be an integral part of the whole Internet of Things to power sensors and such. However all the energy harvesting products I’ve seen are very low power (microwatts) and wouldn’t charge a phone or anything like that. So call me skeptical.
This addresses asimilar claim from a few years ago…
Supposedly running LED strip, just seems way to good to be true.
Yep, if they’re actually claiming to do this, they are 100% full of crap and total scammers.
Nanowatts vs. 24+ watts, total BS!
They have a battery in the reel or some other slight of hand.
