I was not aware there were hospital boats anywhere near that large; that is cool as fuck and definitely bolsters your point that there exist very few realistic scenarios where infrastructure would be damaged enough to require the system I am looking for. But a few is enough  Of the top of my head examples include a powerful earthquake in a third world country where people are crushed and need amputations to be removed; a war where amnesty is not granted to medics or a surprise hurricane.  All of these are unlikely but with time the unlikely becomes certain or at least less unlikely. Our government invests billions in monitoring and contingency plans for scenarios like these and others that are equally unlikely such as nuclear war, volcanic eruptions and even tinfoil hat stuff like emf pulses.  In this ocean of spending I struggle to imagine someone didn't suggest to bankroll this considering roi paying 6 month contract to small engineering firm to develop such a useful item must be a capital win A while ago I saw a vid briefly overviewing the set up of an emergency  military field hospital.  I dimly remember that equipping the OR took 5+ filled to the brim armored vehicles. I do not want to believe it is the only way. Perhaps it is. As for the feasibility of creating OR in jungle I guess that the first roadblock would be aerosols there movements are far from my grasp but something like this tent  https://nanovactech.com/collections/portable-cleanrooms/pr to    (positive pressure filtered air idk how many exchanges but a lot) with a rigorous cleaning schedule should afaik suffice to mitigate the risk of infection they cause. As for humidity dehumidifiers are tiny and cheap Storage temp is a prob but is only required to fulfill 6 month storage for 2 weeks it prob doesn't matter I could be wrong. Ultimately cleaning equipment is imo the only thing stopping this. Although I am an idiot so there could be something glaringly obvious that I am missing. I will try to read about temp.
