Also while I was looking at making dome houses out of polyurethane foam 100%
Ployurethane foam was around $2.65 per pound in 2 (part a and part b ) drums
standard wall filler mix waterproof closed cell 1.5 lbs per cu’ about the same strength of styrofoam and youcan have the stuff mixed up to 16 lbs per cu’ for really hard shit..
Make a mockup of what you want and spray away to make your form in any fanciful way.
I initially wanted to inflate a tyvec material into a series of interconnected domes then foam form the inside 6″ thick voilla, instant house…

55 gallon plastic transport barells used are about $20 or less it will give you 55+ gallons of displacement 467.5 lbs + the amount of plastic so possibly 500 lbs submerged
so 4 would displace a US ton 2000 lbs
I have a written quote from a recycling company to provide food grade, triple washed with clamp on removable lids for $16 ea if bought by the truckload 300 ish if I remember

Assumeing in the tropics and no electrical heating and cooling, actual electrical needs could be very minimal, ie lighting and electronics.
1) minimal btus needed for heating water for showers from direct solar heat gain tubes stored in large hot water container.
2) cool seawater from 1000+ feet down could be used to cool living areas
3) energy could be derrived by the difference in the warmth of the sea level water and the coolness of seawater at depth
4) fresh water could be derrrived by the same ocean temp differences or a variant on option 1 to heat water and use the difference in sea level water and heated water to form condensation.
5) solar electrical panels (PV) for direct conversion of sunlight to usable electricity stored in lead acid battery systems, solar panel laminates are now as low as 50 cents per watt unframed, no kidding you can get 10kw of panels now for $5,000
6) wve energy could be simply used for mechanical pumping like a large lever action pump of seawater to create pressure or move seawater through a thermal system
7) wind energy could be harvested and stored in batteries
8) cool rich in nutrients seawater from deep could be pumped up and spread out at sealevel after extracting themal energy to feed enhance fish / shrimp cultivation
We have just solved, freshwater, hotwater, electrical and an enhanced feeding program for farm sea raised fish and shrimp
Anyone add more SIMPLE technology to the list that the common man can acquire and operate
Perhaps locate in the trash dead zone in the middle of the pacific, then currents ill not move you around muchSeptember 26, 2011 at 8:51 pm #15675
Oceanopolis, he made it pr4etty clear to me when I suggested fiberglassing, that “he did not want a fiberglass boat”
my opinion is it is still a concrete boat with a protective coat of fiberglass and this woul dnot have happened.
to each thier own…
he also misread the grancrete link I sent in his haste, said it was a portland based product, no I believe its magnesium based it is not concrete but very similar.
People must remember concrete is very brittle (no tensile strength)
but you have to give him credit for trying.
GeorgeSeptember 25, 2011 at 8:01 pm #15658
Have you though of using grancrete to patch or make a new hull out of, like concrete in a sack but better 6000+ psi cures in 10-20 mins waterproof

I vote aluminum foil and duct tape for uv protection and or cheap paintSeptember 16, 2011 at 7:23 pm #15562
plants, fish, plankton all use different wavelengths of light, I dont think you can block UV and not affect growth.
IE algae does not grow well in the dark
people growing plants use different lights for enhancing different features of thier plants cycle.. IE hallide lights to grow fast but sodium vapor to flower or vise versa…
In the end its all about candle power and spectrum … good luckSeptember 14, 2011 at 6:56 pm #15537
I al all for keeping costs as low as possible.
Politically I believe we are all slaves having to pay rent someplace, this is why I really want to get some form of seasteading going NOW, I see seasteading as homesteading on the sea.
Basically anything the floats will work as a base but the things I worry about
Concrete the torsional twisting and heaving of the waves, concrete is pretty brittle It would scare me to have 1 single plate crack and sink nearly immediatley.
Concrete boxes or honeycombs have potential, but Im still scared about the torshion and waves cracking them across a 40′ x 40′ or so platform
I like the dome concept with pipe frames as it disrtibutes the weight very evenly with not much point loading
Ala back to the interlinked barrels, virtually indestructable, will not crack or split open, they are designed to hold400+ lbs of water and be dropped x# of feet to a hard surface and not leak per shipping regulations. so they are a hardy structure, a structure that could flex a bit and not have problems, witha geodesic dome on tim and a hexagonal platform the domes weight loading will be distributed evenly.
I feel in any case multiple chambers are needed to help assure security.
What is that black bowl in front of the concrete square platform?
Another structure idea what about melted plasic bottles recast into a spiral deck or plate like the guy is standing on?
There are some instances with a guy making a floating island type thing with plastic boibbles and bags, but I dont think it will hold up in a severs stormSeptember 14, 2011 at 12:24 am #15529
Thank you for linking the picture correctly.
The using of barrels creates many seperate chambers for seaworthyness
do you all think one barrel could be bolted to the next with a bolt 2 large washers and a piece of rubber acting as a gasket waterproofing between the barrels? each bolted to the next anywhere a barrel contacts another barrel?
was also thinking about welding up a steel frame around the top perimeter center of barrels possibly like a railroad track section to be the backbone and around the top providing more ridgity and steel for mounting to other platforms.
Hinging multiple platforms together could be done at corners with more railroad track and pintle hook to act as a hinge to allow up, down and some side to side motion. Imagine 1 bar from one point of the hexagon to another point on another hexagon, 2 sides connected that way to an adjoining platform supplimented by cables going diagonally to limit side to side travel. I’ll try to draw that concept later.
Platforms could be housing, greenhouse, open space decking, open space decking with solar panels. they could be hollow in the center only a ring of barrels, with netting in the middle to be used for fish / shrimp farming pods as well.September 13, 2011 at 4:12 pm #15521
what about using leftover or odd size bulletproof glass, it is usually a sandwich with many layers of acrylic sheeting inbetween glass paines, I see them for sale on ebay regularly

so the 20 ton sub status is sunken for research?
Was it accidentially sunk or on purpose and or who is doing what research on it while sunk?September 12, 2011 at 7:54 pm #15486
So why not just answer a simple question? or provide a link to where the answer can be found
“Ellmer, why cant you answer if you spent your own money on the 200 ton sub or was it a contract project? seems a real easy question , unless well some got the screw…”
So did you and or your company screw someone by not getting the details right?, yes or no…
It is easy for you to call people “umpa lumpa’s” so I guess we should start calling you “poser” and or “scammer”September 12, 2011 at 4:23 pm #15477

elspru, like I said you have a great concept, glad to see you working on it. I like the way yove documented your workings.
Scale, concrete cures best underwater! look for details of underwater curing… I recently saw here a large floor being poured for a shopping center and when they were done pouring the concrete they put 1-2 inches of water on top by putting up a ring around the whole floor and flooded it with water. I asked the forman and he stated that the concrete will absorb moisture form the water and hydrate the concrete better for a better cure. I have heard that elsewhere.
as for 28 days, that is for the rated strength to set in, concrete keeps getting harder as more time goes by but likewide the initial strength curve 3 days has x percent, then 7 days has most and increases until 28 days, after 28 days it still make progress but very small amounts.
I had been thinking of making a ball for a boat, similar to yours but a ball and had given thought to the manufacture, what if you only plastered the bottom 1/4 or 1/5th enough to get it floating then adding more up the sides as time goes on, or looking into submerging the forum and casting underwater building up the sides until above water then when ready pumping the water out with a small pump then the boat would float off the bottom?
Well anyhow just a few of my thoughts on the process.
Have you given any thought to covering the entire shell with 1 sheet of fiberglass cloth and some resin?
