Last time i saw a product claiming to run on energy harvested from radio-waves, it was a kickstarter project that (surprise surprise) turned out to be a complete scam.
It is totally possible to harvest energy from radio waves, it's just such a tiny amount that you could barely light a LED
Yeah that's my point, the energy you can actually harvest is ridiculously small. Even if it was slowly charging a capacitor with this harvested power and saving it for later use, how often can i use the switch before depleting the energy faster than it charges? "oh sorry, you'll have to wait 5min to turn on your lights again, It's not quite charged enough"
My guess is you would get a couple seconds of light before needing several hours to charge it up again.
