@ziphi Yeah, but that's not really a mass market consumer thing, that's audiophile and "i just think they're cool" retro-enthusiast stuff

@ziphi Other consumer devices that use microwaves for communication, like bluetooth and wifi, produce their microwaves through other, cheaper, smaller means that work just fine at the tiny power levels those use, but don't scale up to 1000 watts very well
