I bet you're glad that's over! Now you can relax. The aircrete process sounds fascinating, I'll have to catch some of those vids on YouTube. It seems like there wouldn't be any impediment to building one on St. Thomas.
Yeah, battery day was a bit of a let down to the general public/shareholders but those who understand the technical side of what they announced seem excited about it. I was hearing about a completely new battery chemistry (non Lithium Ion, something like sodium or nano diamond) but they just announced a different way to build lithium ion batteries to make them more efficient. A 500 mile range EV is still pretty darned good, no matter what. Tesla also has a sub $25k car in the works that will be taking a huge market share away from the other car companies. I'll check out QuantumScape. It's only a matter of time before they get these batteries to the point they'll last weeks.
Take care and try to get some R & R!
