@ellmer Congrats on your new-found reasonability. I'm glad you found a good physician that has managed to prescribe what seems to be the right mix.
You've managed to shoot-down every good idea, so far, even helped run-off 2 of the people that are actually building stuff, relegated others to lurker status, and been giving me hell, even though I have managed to make Geopolymer. Doesn't seem to matter that I used scientific documentation and proven engineering to back my ideas and contributions.
There IS no technological 'bottleneck', but a FINANCIAL bottleneck, to include dedicated Incubator Sites, organized libraries, and access to trained, licensed Marine Architects, or Naval Engineers, at affordable rates, organizational support for offshore living, or other support systems.
The majority of what IS being done, other than promote the overall idea, is low-key experimentation and research, by people with serious intentions of participating at an economical, affordable level, by people of modest means, while fantasies of trillion-dollar cities without dedicated water supply, food supply, plumbing, sanitation, or power-supply, dominate the topic.
For instance: You crapped all over my concept of a ferrocement spar-buoy homestead, based off FLIP, until Bob Ballard's interview. Even ragged on me about it, in your bogus investor 'forum', until I deleted most of it, and it took Joe and Randy pressuring you, to close 'my' 'account'... NOW, there is even a proposed wind-farm, expecting to use... ferrocement spar-buoys as platforms...
I sincerely hope and pray you have actually taken a turn for the better.
