I was looking at the SAFIRE project a bit more closely, given it's mentioned here and there every so often, noted the Electric Universe crew (I find them a bit "evangelical" at times.) Of course, this project turns out to be what I'm after, which is people doing actual research and getting results, especially unexpected ones.
As I'm watching through the videos in the
movies section, namely "The SAFIRE Project - Bath England July 2019", I note someone in the crowd I've seen before. Well, if if isn't Hal Puthoff, he wouldn't be there unless something really interesting was going on.
Project SAFIRE later commercialised into
Aurion, with the obvious aim of getting things off the ground. At their current rate of progress, I suspect we'll see more from them than Fusion in the same timeframe, assuming things don't collapse beforehand.
On another side of things, given the tech required, I suspect you could make a working chamber with power output using less advanced technology, especially with Nation-State backing, so Nazi UFOs are not entirely out of the question
