Wouldn't it be more energy efficient and or safe to use microwaves to heat our home's water boiler instead of using dangerous gas or hot electric coils that could catch other things on fire? I'm kinda asking two questions at once, safety and efficiency.
It seems to me that a microwave heats water very quickly and would be a lot safer than using gas or electrical coils because they have to heat a container that then heats the water in a two step process, whereas, microwaves could directly heat water itself. During a usual two step process, you risk the chance of heating unwanted things around it and it'd be easier to confine microwaves, (A simple mesh screen on a microwave oven) than to confine heat. Can anyone shed any information on this?
