Are you somehow entirely unaware of the DEW crowd control devices that have been being used for like 2 decades now?

Yeah, the whole point of these things is they basically microwave the outer layer of your skin, when in wide beam mode.

Or, they can be dialed in to be a more concentrated beam... to uh, internally heat up a bit more than just your skin.

But uh, for legal reasons of course nooo they do not do that and cannot do that.

While it is claimed not to cause burns under "ordinary use",[50][51] it is also described as being similar to that of an incandescent light bulb being pressed against the skin,[14] which can cause severe burns in just a few seconds. The beam can be focused up to 700 meters away, and is said to penetrate thick clothing although not walls.[52] At 95 GHz, the frequency is much higher than the 2.45 GHz of a microwave oven. This frequency was chosen because it penetrates less than 1⁄64 of an inch (0.40 mm),[53] which – in most humans, except for eyelids and the thinner skin of babies – avoids the second skin layer (the dermis) where critical structures are found such as nerve endings and blood vessels.

I would imagine that if you had an emorous amount of microwave energy from an orbiting solar array, being beamed to a recieving station on earth, (ie, a very small small space compared to the distance involved) and it uh, missed, yeah, yeah it would microwave people.

There's also this:

Brief but intense pulses of radiofrequency (RF) energy can elicit auditory sensations when absorbed in the head of an individual, an effect known as the microwave auditory or “Frey effect” after the first investigator to examine the phenomenon (1). The effect is known to arise from thermoacoustically (TA)-induced acoustic waves in the head (2).

Lin has proposed that the Frey effect may be linked to unexplained health problems reported by U.S. officers in Cuba and elsewhere, the so-called Havana syndrome (3).

Probably don't tell any schizophrenics you may or may not know about that.

Assuming 1MW of transfer, and a 10m diameter beam, your looking at 12.5kW/m^2 . Not instant vaporisation, but dangerous in seconds to humans. The penetration was also mean the energy is delivered internally, where it's harder to deal with (short term).

Any viable power transfer beam also, inherently, makes a good anti personnel weapon.

While the maths is slightly better for short range transfers, like drones, it would still definitely not be something you want hitting your body.

Yeah, xrays are also radio waves. That doesn't make them inherently less dangerous. Plenty of people have made mistakes around ground and ship based radar systems too and have accidentally cooked their insides. Just because 5G conspiracy theorists took over that argument doesn't mean it has no basis in reality.

I was in primary school. My understanding of physics was that water is wet not what it was made of.
