Microwaves are technology. /g/ should be aware of solid state microwaves. So basically instead of using a weird vacuum tube, you use transistors that have been doped with massive amounts of steroids. More microwave sources can be used and power can be adjusted more finely, so cooking's more uniform. They can supposedly cook eggs without exploding. Buy an ad you say? Ain't got nothing to sell, no solid state microwaves are on the market and China's gallium restrictions may hold them back.
