Are the video claims valid?

I'm tempted to say it is an "absolute 100% scam", but I'll just go with an "absolute 99.999999% scam". 

All that was missing was for them to say "...and the Egyptians knew about this technology too, and that's how they built the pyramids".

Even if their intentions were honourable, you'd never see a return on your investment in your lifetime.  As far as quantum entanglement goes, the next step massive leap would be to send messages over long distances (or short distances), instantaneously, or in other words 'faster than light speed communication'.  I think most academics will tell you this is a dead end though, much less will you see it in your lifetime, let alone anything beyond this.

I mean they haven't even published a paper yet, and even if they had, it could be a scam, so you'd really want to check how much authority it has with their peers.

At best, they're going to piss all the crowdfunder's money up the wall, on silly experiments with lasers, or they're just gonna take all the money and ride off into the sunset.  The idea they are 20 years ahead of the game is pure BS, with zero substance behind it.  And there is a lot of other misinformation in that video too.

This might have a bit more substance behind it, but remains to be seen how far they are going to get with it any time soon.
