    Default Pycrete [ Sp ] a material to build Carriers / Floating Islands




    Documentry about X projects created during ww2 .. Most outlandish being the Pycrete principal though would have been interesting if such a concept could have been achieved .

    I thought pycrete might have had it's uses. But, not everywhere- the tropics, for example, North Africa- the Indian Ocean. The designed material certainly had some interesting characteristics ballistically. But, what was to be the investment in infrastructure to use it practically? I think, putting a calculator to the problem of keeping the stuff frozen, even in an arctic zone, the energy required for a vessel to be large enough for practical purposes would have far exceeded the manufacturing potential and economic means of the time. I suspect that if there had been successful pycrete examples built and tried prior to the war, the idea may have shown some use- rather like dirigibles- a dead end design that had shown some promise early on and had some infrastructure in place just prior to the WWII start. But, the practical consideration of war, and the exorbitant cost of such a fragile system indicated it was useless in the new war environment. Pycrete would have been a very expensive gamble no one was willing to invest in with so many lives and so much treasure on the line.

    Pycrete was a daft idea right from the start and it is a measure of how desperate things were that it was taken seriously even for a moment. It would have required vast amounts of steel for the pipe work needed to keep it cool. It'd also require that the engines be mounted on the outside of the "ship", a sure way of ensuing that any damage to the ship would damage the engines. Cold moist air condensing on everything metal would have made maintaining electronics a nightmare, let alone aircraft.

    Pycrete's problem was that it was too ambitious. If they were to use it as a building material for defensive positions in the north (say, if an invasion of Norway was to happen) or one-time-use naval vessels (like barges/landing craft) out of it, it might have been adopted.

    There's no doubt that the construction of the material was practical for Canada. Make sawdust, mix with water, let freeze in the winter cold, float it to the warzone via the Great Lakes.

    I say they got the whole thing wrong when they decided to make escort carriers out of it.

    I have to not agree with this. I doubt there was any real value to the stuff except in a perpetually and naturally frozen environment.
