We’re one step closer to wireless meaning literally never plugging things in
Today in Science Express, some MIT scientists announced experimental confirmation for a method of relatively efficient non-radiative wireless power transmission.
Basically, they lit up a 60W lightbulb even though the power source was 2 meters away without making anyone sterile in the process, and it only took 150W of power to pull it off. Imagine setting things on your desk (or on a Microsoft Surface) and having them charge automatically. Imagine never having to plug anything into a cigarette lighter, ever. I doubt you’d want to use it for lights or your air conditioner because of the inefficiency and waste involved, but for small, power unintensive appliences it could be pretty convenient.
I would really like to have access to read this paper for free to figure out how they did it, but maybe later I’ll see if the internet has the info. I’d like to know how the efficiency scales with range. I’m also totally into trying to replicate what they did as long as it doesn’t require a superconducting electromagnet or anything because, seriously, plugging things in is a serious drag. Actually, even if it does require a superconducting electromagnet, I could maybe see if my old physics lab has an old one and, like, some liquid helium sitting around.
