This just in, scientists unveil “a loop of wire”
I keed, I keed. Glad to see materials science improving technologies we have for new applications.
Tesla, himself, is giving a gentle thumbs up from his grave.
Cool, I can charge my car in just 2,680,000 years.
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.
I’ve seen a whole-home wireless charger at some convention. Would be super nifty for home automation and such.
Did they discover it in online news articles from 6 years ago?
Wonder if this can be used to power ZigBee smart sensors. My current battery ones last about 2 years on a coin cell
Do you need to hazardously close to a tower for good stability? Fascinating for the future of wireless power!
It’s almost certainly going to be milliamps or microamps unless you’re inches from something. This isn’t for cellphones and the like but for remote sensors and the like. I also bet they’ll at least have to have a capacitor to store up extra charge for chirping back only sometimes.
That’s really cool.
Uhm, how is this fundamentally different from a crystal radio? I’ve built this exact concept from a science kit, and this is a concept that’s been proven for decades.
