Ah, I have found it!
It is WATER!
No, not just ANY WATER, BUT ORBITAL WATER!
You see to send water into orbit it costs 10,000 dollars per pound, that would be one pint of water casts 10,000 dollars to get into orbit.
Now, that may SOUND like a lot, but in REALITY it is very cheap!
Astropnauts only drink one pint a day (10,000) but they pea out 500 cc, or about 5000 dollars, so in reality you only need 5000 dollars a day to survive on fluids up to the space zone. Cause they have a machine that lets you drink your pea water again. Yum, isn't THAT a good thought (so I hear, I don't know this for sure).
This may seem expensive but in reality it is very cheap, the water to get to the moon and descend it safely is about double that and a bit more for hauling dead weight (fuel for return)
so about 25,000 dollars a pint for drinking water per day for moon people who drive around i their mooncarts all day.
here is a great article.
"There are various ways to estimate the economic potential of the detected lunar water ice as a supporting resource for future human exploration of the Moon. One way is to estimate the cost of transporting that same volume of water ice from Earth to orbit. Currently, it costs about $10,000 to put one pound of material into orbit. NASA is conducting technology research with the goal of reducing that figure by a factor of 10, to only $1,000 per pound. (BUT NOT YET .) Using an estimate of 33 million tons from the lower range detected by Lunar Prospector, it would cost $60 trillion to transport this volume of water to space at that rate, with unknown additional cost of transport to the Moon's surface.
From another perspective, a typical person consumes an estimated 100 gallons of water per day for drinking, food preparation, bathing and washing. At that rate, the same estimate of 33 million tons of water (7.2 billion gallons) (8 million US dollars per day, at todays expensive astronaut prices)) could support a community of 1,000 two-person households for well over a century on the lunar surface, without recycling.
