can we use microwave energy to transfer heat from one place to another without any risk to health of livings?

Question

I mean can we heat up the radiators or something like that using microwave technology or another source to eliminate the cables?

Answer 1

Generally, I'd say transfering energy using a microwave beam would be hazardous to anything living in the beam, however, it depends on the intensity, or beam density. If you're transfering enough energy to be usefull, I'd say it was dangerous, unless the beam was very wide, and your collectors were very large, then the beam density would be low, but such an unfocussed beam would be inefficient.
Microwave radiation is all around us, naturally and artificially generated - background radiation, line of site communications, radar guns, etc.....

Answer 2

Do you mean can we use the same idea behind a microwave oven to transfer heat? Microwaves do not have a heating element, they bombard the object with microwaves which cause the molecules to vibrate and produce heat. So no you would not be able to transfer heat through microwave, and if you tried to use the technology as a heater you would cook all of the tissue in your body from the inside out (soft tissue would go first, ex. eyes, organs).

Answer 3

IF the microwaves were low energy. Say you set the power such that it would imput 10 joules of energy in to a system per second, and had a sensor to say if any thing gets in its way to stop transmition then it could be possible to proform what you are saying safely.

Answer 4

No.

You risk frying them.

And microwaves are interfered with by things like rain.

And if an aircraft flew through the invisible beam - pow.

Answer 5

No
