Agreed. As the oldest of 9 that my mother had, 2nd oldest of 13 in a his/hers/theirs family, with a 13th sibling from my dad and stepmother, I am continually dumbfounded at just how stupid my siblings are. Don't get me started on my daughter and step-kids..., but, my Daddy was a multi-talented, hardworking man, as was his Daddy. When my parents needed a pickup load of firewood, they called me, or paid someone else to deliver it. As the 'step'son, I never expected a handout, and only ever asked for a hand up. My youngest siblings, even the married one, are still dependent on my stepfathers' handouts, while I've been through homelessness and all sorts of ordeals. My great grandfathers were a couple of truckers, an oilfield and mining hand, and one self-made banker.
If my concept ever gets built, it will be because I built the very infrastructure necessary, to build the thing, and survived long enough to build it. One great-grandfather designed a technique for sheathing pipe in cement, in a diner napkin, that is still in use. Spin-offs include the system they pump drilling mud with, such as used at Deepwater Horizon.
I have yet to see the miracle of 'self-healing' cement/concrete. If there's a suitable, cost-effective geopolymer, I would prefer to use that. Adding a heated, curing stage is just one more section of a device that has never been built. Said device will have to work, almost from the get-go, in deeper water, simply due to the way it functions. I'll need to build a pair of small barges, not just for the equipment, but the supplies to make the structure, as well. During the manufacture of my 'stead, they'll be connected, thus my need for the means to connect and disconnect them. If any single step fails, the whole thing fails. Once the hull is complete, and afloat, I can tow it into a disused bay, or estuary, for outfitting. Nice thing is, there are plenty of abandoned oil-rigs in the GoM, to use as piers to tie-off to, in water deep enough to make a nearly 200 ft vertical, monolithic reinforced-cement/geopolymer cylinder.
I fully admit, there is no single part of my concept that is solely my idea, other than the interacting combination. It's an amalgam of ideas that should work, from the way it goes together, to the way it functions, afterward. Hell, the basic method I expect to use to splice the FRTP rebar was invented by Alexander Graham Bell... Something I picked up as a kid, and have used in auto-repair, in farming, and even for the hot-wire fence on my dog-pen, right now.
