  • An industrial machine designed to handle 10,000 psi gas is a little different from a tank you’d take to a BBQ.

    A fuel station will also get resupplied regularly, so any small leaks are no big deal, as there will be a shipment of fresh fuel coming in a regular schedule. Your BBQ tank of hydrogen likely will need to be refilled regularly even if you don’t use it, as any valve that would be cheap enough to mass produce is not going to be able to keep hydrogen in for months while it sits in the garage.

    Then there’s also the fact that most uses for gaseous hydrogen require the above 10,000 psi storage pressure. This allows a useful amount of hydrogen to be stored in a non-comically large container. 2 problems I see with this:

    1.) a 10,000 psi container is fucking terrifying. If that things bangs into something and ruptures, it going to send shrapnel through a house.

    2.) a propane like tank can be opened to the Atmosphere and does not have a regulator built into the tank because most people don’t know how to actually use a regulator. So a 10,000 psi tank with just a hand valve between the user and a jet of gas that can send the tank into the stratosphere does not sound like something that should be available at your local hardware store.

















  • It’s having problems with its RCS system

    The thrusters that turn the craft around and allow precise movement aren’t working properly, they barely got the thing to dock with the ISS.

    Despite what nasa says publicly, I’m sure there’s a lot of internal debate about if it’s even safe to undock the thing from the station. If it loses orientation control while still close to the ISS, it could easily damage the station and kill people. That’s if some of the damaged thrusters aren’t the ones that allow the craft to go backwards, kind of important if you want to leave the station.


  • The US navy has almost as many aircraft as all of Russia.

    The US Army has more aircraft than all of Russia.

    The US Airforce has more aircraft than the US navy and army.

    That’s just planes and helicopters.

    If you think any of the countries you talked about are a serious threat to the US outside of nuclear war, then you’re sorely mistaken about how truly insane US defense spending is.


  • More an Anti-computer-system-that-happens-to-have-wheels narrative.

    I want a car. I want it to turn on, take me from point A to B, and maybe play some music or an audio book while I’m driving. It should tell me how fast I’m going, and how much further I can go before it needs to recharge or refuel. Give me a few buttons for basics like turning on the heat, AC, lights, and the windshield wipers.

    That’s it. I just want an affordable car that can take me somewhere. None of these EV manufacturers are doing that. They all focus on software packages to set them apart from the rest, when if they just focused on making a usable, affordable car, they’d corner the market.

    Let them fail until someone makes something that actually does what it’s supposed to.
