  • 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.


  • What I don’t understand is why no politician who’s against this has proposed an education act under the guise of national security.

    What republicans are doing with education is very dangerous. Stupid voters are easy to manipulate, which seems to be the goal, but they have to do more than vote for the other 364 days a year. Having a poorly educated population means you have less engineers designing infrastructure, less trades people building that infrastructure, less doctors to treat injured and ill people, and less skilled professionals overall. The US is largely in the economic and geopolitical position that is in due to the manufacturing and research capacity we had after WW2. For decades, the US was where people went if they wanted to be at the bleeding edge of design/research, because we had very good higher education and the skilled manufacturing to bring those designs to life. Attacking education only hastens the decline of that legacy. A few decades like this means the US will no longer be able to make the advanced military equipment used to project power across the world, or US companies not being able to find people who can maintain, improve, and innovate on products without hiring foreign contractors. If Desantis’ attacks become a national thing, they’ll be putting the US on a fast track to rapid decline and economic collapse.


  • The Thing Ukraine needs most, according to Ukraine, is shells for their artillery.

    No one knows where the US spends almost a trillion dollars a year in the military, but it’s apparently not on artillery shell factories, cause we only have 6 of them.

    We simply can’t produce the number of shells Ukraine needs a month, and we’re already sending them shells from our stockpiles. The problem is that the military won’t put all their eggs in one basket. We need those shells in reserve too, so the government is only comfortable sending whatever shells we can reasonably replace.

    Giving Ukraine training and access to US stockpiles sounds great, but what if they use up those stockpiles and are still at war? Ukraine’s doctrine is very different from US doctrine. Primarily, They’re using far more artillery shells then the US ever thought it would need, and ukraine would rapidly burn through decades of reserves that were intended for shock and awe style wars with air superiority and highly mechanized infantry.
