I don’t remember. Arthur D. Little Corp did a lot of studies about rectennas and microwaves and so forth a long time ago. They had entire generations of mice raised under a micropower microwave field to see if it caused any damage.

So if you really want to know, look for those reports. Mid 80’s, maybe? Microwave power from space, microwave power in space, should get the reports.

It’s sad to see what we had planned back then, compared to what we are doing now. Now, India, China, and Japan are all considering permanent space presence including beamed power and a permanent space infrastructure. Somewhere along the way we abandoned space.

“Now, India, China, and Japan are all considering permanent space presence including beamed power and a permanent space infrastructure.”

I say good luck to them on getting the spaceplane built and operational. It’s not impossible for them to make it work but that is a very challenging technology to implement. Should be interesting to watch.
