Have you seen The Engineer Poets thoughts yet?



Interesting comments on Robert's concept of using microwaves for his LONG Awaited water heater.

Courtesy of the Engineer Poet:

Microwaves are not magic. Generating microwaves is a lossy process. You can turn on a magnetron in a fraction of a second (if its filament is hot), but you're going to lose up to half the input power as heat in the device itself.

Point 1: It is impossible for a microwave-based water heater to require less energy or deliver hot water faster than an on-demand resistance heater.

Point 2: It is very unlikely that the microwave heater will have lower losses, because it will need to keep its filament powered for instant-on operation, and the heat dissipated in the magnetron (which will have to be water-cooled) will leave some unusable heat in the machine itself when the water stops flowing. That energy is lost.
