  • I’m writing only based on your text, not the video, please excuse any doubling of content.

    It is easier explained if you build an imaginary machine instead of lifting / lowering that does the same thing. The single most important thing to understand is that the lower the pressure the less heat you need to add to boil something. There are funny graphs for each liquid (for example https://courses.lumenlearning.com/umes-cheminter/chapter/vapor-pressure-curves/ ).

    The intro explanation

    The water in your containers will behave based on their individual combination of pressure and temperature. I’d at any point the water vapor falls below its boiling point at the current pressure it starts to form a liquid. At this point you’ve made a fancy rain machine.

    Note that water itself adds pressure to a system because of its volume even as a gas

    A machine

    Imagine you have a container at 100 mmHg which according to a random online calculator leads to a boiling temperature of 50 degrees C.

    Now you heat this up and lead the water vapor into another chamber which has only s pressure of 10 mmHg. Water has a boiling temperature of only a bit over 10C there! So you keep it at 20C to be sure the water never gets liquid again.

    But wait: now you’re adding water vapor into a low pressure container - you’re literally pressing a gas into it - so you increase the pressure in there.

    The first container, the source of the gas, becomes irrelevant: As soon as the additional water increases the pressure to around 20mmHg it starts condensation again as now it’s boiling point moved above the 20 degrees.

    The flaws

    As you’ve asked for the downsides: it’s a very convoluted way of manipulating water to achieve the same result as simply heating it. You would need way more energy to lift the containers far enough or otherwise decrease the pressure than the energy needed to boil it.

    Other than energy and logistics I don’t see a downside. Liquids don’t behave differently in terms of boiling no matter the source: pressure, temperature or a combination.







  • I assume we’re in a similar boat so let me assure you: no, you won’t - because we wouldn’t even realize it happened.

    Only after s few months one of us will recall this thread and be like “oh, yeah. Twitter. Seems really dead finally. Good.”

    And to be clear I expect they person to be you because my memory is awful.




  • No it’s the complaint about one of the few transparent revenue flows Mozilla managed to pull off.

    It’s disabled one step deep on the settings

    There is a shitload of stuff going wrong with the Mozilla foundation and this doesn’t even make the top 10.

    That’s the reason for my down vote: it’s nothing I want this community to focus on. It’s basically engagement bait with the topic “ads bad”.










  • One thing that was only mentioned briefly by someone else is the physical button turning on the computer.

    Similar to the paperclip test figure out where the power button goes into the mainboardw and bridge that with a short cable. Is possible that by moving the case the old button lost a cable.

    This is just one more thing to test though, it’s really trial and error as you know :)


  • From what I understand: CasaOS is simply an abstraction layer and takes away a lot of the manual work.

    I agree with you that this shows down learning quite a bit.

    I see three ways forward for you:

    a) switch to a Linux base system, Debian, arch, nixos, whatever resonates and set up everything from scratch. High learning curve but no more hidden things.

    b) same as a but as a separate setup. This is what I would recommend if you have the time and cash. Replicate what’s already working and compare.

    c) figure out how to do things manually within the CasaOS framework. Can’t help you there though :)
