    Climate Change(d)?

    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?

    Climate Change(d)?

    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...

    Climate Change(d)?

    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.

    Inside Germany’s Giant, Hungry, Flightless-Bird Problem

    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.

    Climate Change(d)?

    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.

    Climate Change(d)?

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

    Climate Change(d)?

    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.

    Do you think any aliens exist in the universe?

    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...

    Do you think any aliens exist in the universe?

    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.

    Do you think any aliens exist in the universe?

    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?

    Do you think any aliens exist in the universe?

    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...
