I wonder what happens to the air craft or living things when they get caught in this high energy beam

These beams contain 1/4 of peak solar energy at more benign wavelengths. Long term exposure is probably safe but might not be. Any amount of time measured in any unit less than years will be safe.

That's what they said about leaded gasoline and asbestus.

We do not know, it might cause cancer.

Leaded gasoline and asbestos weren't studied before introduction. This has been.

RF does have the slight advantage over asbestos that you can just turn it off if adverse effects are observed.

Don't know about asbestos, but everyone knew lead was bad. Profits just spoke louder.

Romans knew that slaves in asbestos mines didn't live long.

Roman slaves in any sort of mine didn't live long. It was considered by many to be a sentence worth than death.

Not was bad for lead but is bad. Lead is still used in airplane avgas.

And solder for electronics. And bullets and for shot pellets.

It probably would in case you spent significant amounts of time between the transmitters but that should be pretty easy to avoid.

Yes if you climb the barb wire fence and ignore the "keep out" signs and then put up a tent and sleep there for a year you will probably slightly increase your chance of getting cancer.

They will have predominantly female offsprings

The beams could be quite narrow. We did the calculations in a course I took and from what I recall, all of America's power could be compressed to a 15 meter beam. So they could probably just setup a no fly zone around the beam. Birds might still be a problem, but don't the alternatives (e.g. wind power) already kill birds?

Lets say Im not very interested in practicality but just the theory of this. How does it work? How can I send power from one side of my room to the other if I don't care about paying more.

Unfortunately, it's been too long for me to speak with authority on the specifics of what energy levels would be safe to do that for. However, from what I recall, in general there shouldn't be anything preventing that at reasonably low power levels. You could also use something like: https://en.wikipedia.org/wiki/Waveguide_(radio_frequency)
