Way to waste water.

Wait till musk sees this

I don't think that much water was used....

There is a shortage here on earth....

Shortage of water is not the issue.

Getting water to people who need it is the issue.

We have entire oceans full of water, and we have the capability to make it drinkable. It needs to be made more widespread and made more globally available.

Too expensive. It would make fresh water the cost of rent.

Are you joking?

It's currently expensive. So is renewable energy.

That doesn't mean we should put it aside and forget about it.

That we need to invest in more ways to access our vast reserves of salt water and turn it into fresh water? Why would that be a joke?

You’re correct we do, but there is also a reason why it isn’t already happening now on major levels. There are plenty of super wealthy countries just importing fresh water, even when they have ocean access, it’s because the technology just isn’t where it needs to be for capitalism to be interested. Hell it’s not even really where it needs to be for socialism to say let’s go baby. Hopefully soon tho

This sounds suspiciously like just burning hydrogen

Steam punk zeppelin on the moon

Turns out SLS is also steam powered.

But not the side boosters.

Wow, I sincerely apologize, I meant to reply to a different comment. I am so sorry.

Props for leaving the original comment up for context

Be careful with that, guys! Water vapor is a greenhouse gas!

Water brings it's own oxidant!

If they put a large useless gear on the side of the craft then my steampunk dreams have been at last realized.

Is it too much to ask for a big brass flyball governor?

Just like early submarines, let’s try steam, diesel, electric, etc. something will stick.

It probably has a reaction wheel.

Pft, congrats on the entry level rocket engine Japan.

I've never heard of a flyball. I have heard of a flywheel or a reaction governor.

I suppose I'm not well versed enough in steampunk technology.

Worse than co2!

I could be wrong, but I *think* it's not as bad as C02, but it is by far the biggest contribution to greenhouse effect simply because there's so much more than anything else by orders of magnitude.

I blame Rockefeller and Thomas Edison for why we're not living in a steampunk society, clearly that's the suprtior technology, but self-intrest groups blocked certain tech and promoted certain energy sources and that's why we have climate change and no steampunk. Frigging billionares ruin everything.

Reaction wheels are kind of like the inverse of flywheels, they're spun at constant speeds and then have their speed adjusted to modify attitude. https://en.wikipedia.org/wiki/Reaction_wheel

No, one molecule of water has much worse greenhouse effect than CO2, it is all about vibrational levels.

These are thrusters used in orbit. We used to use compressed gas. Water is better because it’s doesn’t have to be stored at high pressure and can serve multiple purposes (coolant, consumption, etc.), the “problem” is that you need a boiler to produce the steam which in turn requires power. This test seems to indicate they’ve found a solution that meets size, mass and power requirements.

First Dilbert was doing this, now Japan is using Steam on spacecraft. What an age in which we live!

I liked this explanation : temperature controls how much water vapour there is, there is higher temperature due to c02 and other non condensing gases. Water vapour is 60% of the warming in a ongoing feedback loop... https://www.acs.org/content/acs/en/climatescience/climatesciencenarratives/its-water-vapor-not-the-co2.html

Superheat injected spurts of it on it's way to the nozzle housing?
