that is what stops the Rover for months which is on Mars and solar powered

it is only 1% of earth, not enough mass blowing to really generate a lot 
of power, and does Mars have strong prevailing winds ?  think not.

they need power at night, and when the wind is blowing, so they must use 
a nuk.   no need for wind power.  some solar may help but dust is a big 
problem, how do you clean it with out water or personel or scratching it ?

nope, they sound good, but not enough power during night. and wind is 
too wimpy

yep, most all daydreams wo the engineering, no cost constraints

it is mass, the mass of the water carrys far more heat than air, higher 
effeciency, etc.  Humans require a lot of water.

dry cleaning is with fluids, they used to use carbontet, but that causes 
cancer.  I saw a film from the early 50;s of people walking down into a 
pool of carbontet, and back out again, all their clothes were cleaned.

but you cant have an air polutant on the station, therefore no dry cleaning.

arizona, austrailia will benifit, they are full of rocks and sand.

there are safer reactors, they would probably just scale up one like the 
use to power deep spacecraft,  radioactive stuff heats up therompiles. 
ultra reliable, lasts long time.
