Re: nikola tesla
well i dont know the composition of microwaves.
But they do carry some form of energy--I know for sure that intensity of that energy is very low.
nothing like electromegnatic----but more like soler.
the reason i said that is at the recievig end those guys(who were doing the project) were using a panel similar to solar cell sheet,
size appx:: 3' X 4' (feet)
At that point they were just measuring the powet passed.
they had not done any mechanical work with that.
I did not noted down then specs. And yes energy omitter was just microwave oven.
No one was sure about success.
