Wind is a gas, correct? Gas can be turned into liquid. (A) Why don't we turn wind into liquid in our own planet, just to prove that it's possible. And (B) Why don't we turn Mars' wind into liquid? Mars has a climate. There must be wind present somewhere in its atmosphere. If we turned the wind into liquid, we'd have a sustainable source of water on the planet and thus we can start inhabiting it. Is there something I don't understand, cause it really seems quite simple :P
