Besides reddit front page, this stuff also appears in enough other pop culture podcasts and the occasional NYT expose that it's out there in the popular zeitgeist. Unfortunately, here it's just my science immune system flaring up on a random internet board.

Also, between the "could this be used for vehicles" parent comment and that downvoted interdimensional energy transfer comment below, it doesn't take a Aliens-Did-the-Pyramids Guy to see what dots were starting to be connected... I might as well be the one to flag it explicitly and earn some imaginary internet points.

But who knows, maybe I'm actually the goberment disinformation agent trying to keep all this under wraps...
