If it involves electricity, magnetism, and the death ray designs he
actually patented, then no, no it is not possible. We know what the laws of electromagnetism are, and the Tesla Death Ray doesn't perform as advertised in a universe where they hold true. And we knew this back when Tesla proposed the idea, which is why the military (rightly) turned him down. Only trouble is, Tesla
didn't know, or didn't care, what the laws of physics governing the phenomenon he was trying to exploit were.
He does not deserve funding simply for having an idea, regardless of his role in the early days of AC electrical engineering. Not if he can't articulate how or why it works... which is my point. He couldn't do it then, when people actually seriously looked into his proposal, and I see no reason to assume he can do it now.
Now, if he
can, that's a different ball of wax. But I'm roughly as confident that he couldn't do it in this situation as I am that the sun will rise tomorrow, and for much the same reasons. So I don't take that possibility very seriously unless it comes up.
We seem to be disagreeing not so much about technology but philosophies for Alternative History. You seem happy to ask What If about (say) the SASSTO being built and actually working as advertised (even though it almost certainly wouldn't have IIRC) because that was a historical proposal. But it sounds like you would baulk at the idea of the French building it, because that is not an idea from recorded history. That seems a very tenuous distiction to me. (Sorry if I keep coming back to space based technologies. But that's what I know about.)
If the US can build something, I wouldn't be surprised to learn that the French or the Russians could build it too. Those are technologically advanced nations; one might fail to duplicate another's project, but it would not be beyond the bounds of sanity for them to succeed.
Whereas for, say, Zimbabwe to build its own space shuttle... now that would be beyond the bounds of sanity. And Tesla's death ray is even less plausible than that, because it violates actual laws of physics, instead of the laws of economics.
Polywell reactors lie somewhere in between. They are not a proven technology on a useful scale. I'd love to see them work, but until I do I am not going to make confident statements about what it takes to
make them work. And I don't think you should, either.
And yet, this is very much the situation with the Tesla death ray. Tesla never managed to answer the obvious questions about how his device could work, given that it seemingly ignores the laws of physics. Indeed, he may not have even realized that the questions needed to be asked; he wasn't very stable in his declining years.
I can actually imagine a working submacopter
more easily than I can imagine a working Tesla death ray. A submacopter would probably stink to high heaven as both a submarine and a helicopter, but it
might be able to propel itself underwater and fly in the air. Might. For all I know. Whereas I know a number of reasons that make me extremely skeptical that any EM weapon Tesla could possibly design would be able to do what he claimed.
