Oddly enough, the "energy harvesting switches" they used in this are commercial products! https://www.digikey.com/en/products/detail/zf-electronics/AF... https://switches-sensors.zf.com/us/product/energy-harvesting...
I made this slim PCB a few years ago with a super tiny NFC chip on it that can harvest energy from NFC:
Made it into a business card as you can see.

> I've always wondered if you could harvest that same radio energy to power other things without batteries That's how passive RFID tags work. The tag has a tiny little computer, and you hold it near a thing that emits an electric field that energizes it.
I think the poster wants this to work without the “you hold it near a thing” part.

I heard a tale in the days of yore where a radio station was not getting the range promised by the laws of physics. When they did some investigating they found an engineer that lived next door to the tower was syphoning power from the radio waves as part of a home experiment. I'm not qualified to determine the plausibility of this, but I hope it's true.
Can you siphon power from the sun so other people can't get its radiation, without you covering the entire surface with something like a Dyson sphere?
Beautiful, is a dream to have a device that you can forget about charge it and "range anxiety", I hope it will be implemented at least in smartwatch in the next years.
Looks like they used an existing emulator and this was mostly a hardware and memory integrity experiment. I’d love to see this approached from the perspective of “how clever can we get with the emulator itself to save power?” When I wrote mine, something I ran into was realizing that often the CPU and PPU are just doing the same thing over and over and over. If only I could cache all that work. For example, you don’t…

Cars usually lacked wall plugs. You could get ones that plugged into the cigarette lighter, but my parents at least were unwilling to string a cable through the gear selector to the back seat.
The trick is negotiation. Start by trying to bum a cigarette off mom. Then settle for using the cigy lighter for your gameboy

That was a pleasure to read through. Made me think of literate code.
