i don't even understand why they don't just have simple quartz/carbon like the old school heat lights, and you just need a good thick carbon coating on a steel pot bottom to absorb it and reflectors under neath it should be amazing... infrared permissive coating maybe so it doesn't look so bright but honestly the amount of heat that comes out of one of the foot long vertical carbon coils of my IR heater i don't understand why they don't use these with heavy pyrex pots for cooking, it would work perfectly, even the heat would penetrate directly into the opaque objects in your pot, instead of slow conduction and convection processes... maybe not so great for boiling, that probably is where gas is king

honestly though, there is not one type of electric cooking device i can honestly say that i like except maybe for grillers and again, those should be carbon quartz elements, they are so frickin hot lol

must be some reason why carbon coils in vacuum quartz tubes aren't used, but they would work so well i'm sure
