Hey flight attendant, throw another log on that fire, we're losing altitude

Wrong. I was told that only black people have invented anything. This is fake and gay.

That's pretty neat. Although it was oil burning rather than wood or coal. I'd imagine carrying all the water affected the rangesomewhat. Wonder if it could be harvested from clouds somehow.

Pause the video at 32 seconds to study the diagram. There is a condenser to recover water from the used steam.

I'm not clear whether all the steam that you see in the video is exhaust vapor from the burner, or whether some "working fluid" steam gets vented.

Huh, so there is. Genuinely curious about this tech then, like what it's efficiency is like compared to IC engines.

I have a general theory that vehicle tech is so geared towards military requirements that civilian vehicle design is heavily skewed away from the optimum. Like with rockets I suspect a baloon or air breathing first stage would be much more efficient, but it's useless for military applications.

We have adjustable seats because of the Air Force.

Yeah... that's another huge issue I take with government funded tech. Whenever the resulting tech is useless and ignored no one talks about the waste, but if it's useful and adopted everyone says "we wouldn't have X without the institute of Y".

Which of course is nonsense. There's no way car companies would not have come up with adjustable seats without military research.

I see it as a matter of resource allocation. Right now, military is where the money is at, and so the that's where you see a lot of innovation. Well, at least until the diversity thing.

As for useless tech? I think that that's just a by-product of experimentation. Sometimes things come out and are just a dud. It's part of the cost of innovating new shit.

Eh... to a degree you're correct, but private businesses tend to be a lot more careful with their R&D cash. There's all kinds of waste in government institutions/contractors that would never fly anywhere else.

Anyhow, the point is that when governments develop something they tend to develop something big and expensive that only they can afford. When private companies develop something they tend to try to make it as cheap and universally useful as possible.

That sounds like a terrible engineering concept.

Decreased air density at higher altitude would undoubtedly decrease steam, hence power. The higher it goes the slower it goes until it stalls out and death dives like a rock with wings.

The steam system is likely a closed-loop system.

Huh? At lower pressure it gets easier to boil water, not harder.

[ - ] UncleDoug 0 points 3.2 yearsFeb 12, 2022 22:51:06 ago (+0/-0)

yeah it will boil at a lower temperature higher the altitude, but the higher it goes the less steam is also produced.
When atmospheric pressure is lower (higher altitude) it will require less energy to bring to a boil which is true, but there will also be less power the high you travel.
