  • yeah I see that. lube would get a big need, but my car runs out of gas several times before I need an oil change and retail stores do carry oil. ironically canola oil and vegetable oil can be used as motor oil. when you run out of oil then things start to grind to a stop.

    but machinery would become too costly to maintain and people would stop using it. if a valve broke on a engine I doubt people in the post apocalypses would repair it. unless it was part of a town where people would have both the need and expertise to fix it. there would be easier to maintain alternative of machines that wouldn’t require lube, filters, replacing of metal parts.

    after a century an internal combustion engine would become unusable scrape













  • true, i guess i was thinking salt water distillation, so maybe contamination would okay. but I asked ai and since it would only be water vapor and that pressure would be temperature dependent then at room temp the would be 0.03 atm so there’s nothing in the vapor part. (at 100 C it would be 1 atm is okay)

    there is benefit to putting a still in a vacuum because it will absorb thermal energy and lowering boiling point save energy



  • You could lower the bucket to boil the seal container.

    I do have trouble imagining two containers with two different pressures but I get you can have a pressure valve like in a refrigeration system.

    The pressure on the seal container would seem to be the same pressure as the phase changes. The container in the video was crushed by the atmosphere so that implies the pressure is lower than atmosphere post phase change.

    But there seems be an issue once the water has became vapor like would the boiling point move enough so that the water would condensate and would condensation reduce the pressure thus lowering the pressure and boiling point.

    There would be water in both the containers and tube. Seems strange that water in the tube at the vapor/liquid barrier would evaporator then condense in what’s essential a similar environment. Its possible when I think about it just the seal container water can evaporate and go back into the tube

    I can’t really do calculations because I don’t know the process yet, but I think boiling water would be more energy than lifting water 34 feet since water heat capacity is so high.

    Right now I do think the flaw would be it being a slow process or even inefficient





  • I want to encourage fedizens and Internet user to collect their own data and run their own algorithms since it’s worked well for corporations in general but to keep using their services. Seems as though people enjoy algo based on their data.

    It’s neat that fediverse has a general principle of not collecting user data, so if more people used fediverse instances more often then less Data going to corporations. This browser extension is outline of how collecting your own data can affect your experience with fediverse. There’s so much you can do with your data and data from api
