Nitpick

You compress the chamber after removing the solids? Know I don't know if that's energy efficient, and I'm definitely not saying it is, but where did a filter come in?

What would you need the filter for?

In your kitchen, yes. In an industrial setting where saving energy is the key to commercial success, or to public approval, a *lot* of the energy can be recuperated by having a countercurrent piping for heat exchange and recuperating some of the heat of condensation. Your output isn't stream...

And even if you did boil it, you could significantly lower the requirement of energy by recuperating much of the condensation heat and with a clever anticurrent heat exchange piping.

Camels are pretty much extinct in the wild where they come from. As are horses, and hippos and rheas also seem to be thriving better abroad than at home. I don't think that's the case for goats and rabbits.

German rheas, Australian camels, North American mustangs, Colombian hippos...

Still the wrong unit. Mass is kg. Heat capacity is joules / (kelvins*kg) Temperature difference is kelvins All you end up with is joules, not joules over time. There is no time parameter in the input.

Because Watts is not a unit of energy, it's a unit of power.

Watts per litre may be a valid unit for the energy it takes to compensate for evaporation losses in an open body of water (although arguably that's better expressed in warts per square metre of open surface) it isn't a valid unit for production of fresh water.

Titan's is. Now, Mars is off course more exposed to solar winds, so it may dissipate faster. That's not going to be terrible problem for the first few hundred thousand years. If we are planning longer term, we'll have to keep crashing a medium sized comet into the surface every so often to make...

Having people take turns living in the underground cities just in case something real bad happens without prior notice is still orders of magnitude easier to implement than a self-sufficient colony on Mars.

In basically all those scenarios, the earth after the catastrophe is still a more livable place than Mars will ever be. The worst case scenarios basically say "the air outside an hermetically sealed bunker becomes permanently unbreathable" - well, the air on Mars already is. An underground...

Why do people treat the guy with the overpriced electric vehicle as an authority on anything other than overcharging for cars, again?

The nearest large galaxy is the Andromeda galaxy at 2.5 million light years away. There are some small galaxies en route, but their combined size is just a fraction of our own galaxies. Taking two and a half million years to double our population by reaching the next similar sized galaxy comes...

trillions, more likely, assuming it is even possible. It would, however, only be centuries before stagnation would become the norm for the human race. What good is it for the people of earth, or of a near-earth spacer world, to know that out there, thousands, millions, or billions of light...

Yes. For a few centuries. What good is that?

An what would the growth rate of the space occupied by the human race be? Remember, expanding in all directions, the space grows in proportion to t^3. By the year 49,999, we can hypothetically reach a volume of 4/3 * pi * 49,999ly^3 - that's 5,235673603×10¹⁴ cubic lightyears. With the same...

Sure, there could be a rim of recently settled worlds where growth still happens, and that send out colonising ships to the virgin worlds beyond. The reality for 99% of humanity (a figure that would be growing over time) would however be one of a finite and constant supply of resources and...

If your idea of space utopia is a universe with a large and growing core of filled up worlds are living in stagnation, with nowhere to go since all nearby worlds are filled up, and all those further away will be by the time you get there, and a small and in relative terms shrinking rim of...
