I would use multiple smaller rebars rather than one large one. Also the twine does work well and the mesh. We have had at least a dozen concrete canoe college teams use our basalt mesh over the last few years-they all had great success. Unfortunately the completion is sponsored by the Portland cement industry so the rules say the colleges can not use things like geo-polymers (great lets stymie education and keep the same old same old forever) kinda wrong in my book. By the way here is a vaginal design ideahttp://www.techinsider.io/floating-city-university-manta-ray-2015-9
Hard to imagine the "manta ray floating city" surviving even in a Cat 1 hurricane,....
It's gotta be designed as a baystead I would assume.
I don't know mantas seems fair pretty well and they fly out of the water a bit too.Does look somewhat similar to some of the ideas I have seen here. Personally if the whole thing were able to submerge for a day or two to a safe depth it could survive lots. I used to surf and be just feet underneath gigantic waves no problems.
A what kind of idea?
But the colleges have to use Portland cement-because it is financed by the Portland industry-so it ruins the progressive thinking and future advancements of concrete. I am almost surprised they let them use our basalt mesh.
That spiral cage could be basalt as our coils are 328 feet long and it could wrap around the whole thing as one piece.
The look of that posting on tech insider
The video never downloaded, i didn't see any pictures.
That was actually built??
I cannot tell which way it is supposed to be moving, looks to me like either way it's going to scoop water up over the hull.
I don't think so it is the artist designers conception.
Then it's a waste of my time. For what it's worth, "built" is past tense of "build", it means it's been done.
It's front is to the right. You can't see the underside, but I'm thinking the two places where you think water would collect would be above water and it would float like a trimaran.

The fact that progressive thinking is "coded out of existance" in a rule infested engineering world is a problem. Progress needs "spaces of freedom" floating structures can be such a "space of freedom and innovation for advanced concrete engineering going beyond what "concrete base engineering covers with norm aplication" - many interesting materials are available now...
Interesting.Post must be twenty character in lenght.
