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

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.

No Idea, never went to.school in USA. They haven’t cooked anyone while sending them to the moon so can’t be that bad.

I’m sorry, you know the precise frequency that would be used by a fictional/speculative ‘microwave’ beam emmitted from an orbiting solar array?

You… don’t think that ‘microwave’ might be technically innacurate, but broadly colloquially understood term, to describe the broad concept?

Like maybe a ‘phaser’ weapon, or a ‘lightsaber’?

It’s the wrong frequency to cook anything.

The idea that microwave ovens use some specific frequency that’s good for cooking is a myth.

Dielectric heating occurs over a very broad range of frequencies. What actually matters is the energy density of the EM field. A microwave oven cooks food because its putting more than 1000 watts into a small confined space, your cellphone doesn’t because its transmitter is shooting less than 1 watt into the open air (where the energy density quickly diminishes by the square cube law).
