I never understood the "divert power from life support" trope of Star Trek.

I mean, how much power could that possibly be?

We essentially already sustained prolonged life support by using a tiny batch of primitive batteries and fuels cells during multi-day trips to reach the moon in the sixties.

With efficient 23th century tech, life support should be almost self-sustaining using ambient waste heat or something.

Always has been one of the major suspension-of-disbelief efforts for me...

    Air-conditioning is pretty power intensive and The Enterprise is a big ass ship. That's not even counting the other things life support does (like heat and CO2 scrubbing), just the air circulation.

    But even on the show, there's been a couple times where they mention the power from life support is nearly negligible. 🤷‍♂️

    Wouldn't gravity generation and inertial dampners be part of life support? Going max impulse after turning those off is likely to end up with a lot of raspberry jam coating the walls.

    Inertial dampeners probably not; that just stops the ship when not giving any thust because there's nothing to slow the ship down in space once it has momentum. The fake gravity on board tho, may be part of it. Not sure how the gravity plating is supposed to work; but I would be willing to bet there is technical documentation about it somewhere. Unless they just, like... Constantly barrel roll to create "gravity" that way 🤔 (gravity in quotes as it would actually be centripital force).

    Inertial dampers are how the crew can survive high-g maneuvers, they'd be pinned to the back wall and have their skulls crushed by their own faces if they suddenly went to full impulse or warp without them active.

    I loved how The Expanse handled high speed turn and burn in space.

    Fuck Syfy.

    Not watching Star Trek for the scientific accuracy.

    And even the Expanse has some instances of bad and/or hard to believe space tech depictions, probably mainly due to production cost restrictions.
    Take the whole bridge design of the Rosinante for example, with its gaming chairs or whatever acting as high-g-chairs. Sure...

    So, you will always have almost always to engage that "I want to believe" mode.

    For another more TNG contemporary show with mostly credible science, I can also strongly recommend Babylon 5 (which feels like a kind of predecessors to the Expanse).

    Another good example on how bad the actual details of the science are in most of Star Trek.
    Warp moves you by compressing the space in front of the ship and stretching it behind it.
    Your frame of reference in the middle of it stays at rest.
    So no stains on the wall.
    Impulse power would be a completely different thing, though.
    But even that the writers managed to get wrong most of the time, treating it like a kind of fixed absolute speed that you achieve, like the max speed of a car, instead of the steady acceleration capability it actually is, with no max speed besides relativistic limits.

    I'm pretty well convinced that gravity plating has to be negligible power draw or possibly even passive technology, since they've boarded centuries-old derelict ships that still have artificial gravity. Maybe the gravity plating contains some exotic space-warping material that generates a gravity field. That could also explain the times when someone becomes intangible and can walk through walls, but don't fall through the floor.

    Air-conditioning is pretty power intensive

    Even that should still be minuscle compared to getting rid of the waste heat from a huge antimatter reactor.
    Feels like trying to get your Ferrari faster by switching of the cockpit instrument illumination. Not even worth giving the command.

    How does transferring heat out of a ship work? On the one hand, it's really cold in space, but on the other, there's no substrate to absorb and transfer the heat.

    From a thermodynamical standpoint, the whole Enterprise is something of a mess.

    But, hey, if you already have a "Heisenberg-Compensator", also having a "Boltzmann-Compensator" is probably not that implausible... ;-)

    And you can always re-arrange the sensor arrays if you're ever really in a pinch, but it'll take some time.

    Thermal Radiation, you send it somewhere else. It’s how the sun heats our planet.

    Isn't thermal radiation kinda slow, though? It's basically air cooling, but without air or fans.

    It is, yes. A large fraction (about a quarter?) of what looks like solar panels on the ISS are actually dedicated radiator panels. The solar panels are angled to face the sun, and the radiators are angled at 90 degrees from the sun, to face empty space.

    They use AI everywhere. That’s power hungry stuff (and people will deny it is).

    There is an episode where Voyager is looking for a fuel source because they are dangerously low.

    They cram all the staff into two decks and pull all life support from the other thirteen. It only gets them an hour of propulsion at one-quarter impulse thrust.

    Which is basically classical atomic sublight rocket tech.
    So some additional ability to just coast between planets when you are already in a star system.

    It's just written in to add weight to a tense moment.

    It’s just written in to add weight to a tense moment.

    I know the reason why they did it.

    Still annoys me slightly. Actually even more than the techno-babble that is mentioned by most as a somewhat annoying thing written in.

    But I don't watch Star Trek for its scientific accuracy, so it's ok.

    As already said: It is still manageable by suspension of disbelief to enjoy the strong aspects of the show, which mostly are not the specifics of the science-based things being shown (in contrast to the underlying ideas - those are often great!)

    I realize now I should have answered the question differently. The life support uses power by a reverse band of takiyons to a flow emitter. This then spread across the ship via a neutrino wave to a tungsten pulse generator.

    That's why it uses so much power they have to divert it at times.

    Moreover, what exactly is the life support system doing that means near-instant death if you turn it off? Breathable air and heat should last for hours at least.

    Exactly.
    Not only is the power requirement pretty low in comparison, but the system should also show a really sluggish response, especially when considering the sheer air volume of the Enterprise.
    Biggest issue would probably be heat buildup after some time
