The Prospects For Lunar Mining
MarkWhittington writes "With the discovery of vast amounts of water on the Moon, some frozen in the shadows of craters at the Lunar poles and some chemically bonded with the regolith, interest in lunar mining has arisen among commercial space entrepreneurs. Paul Spudis, a lunar geologist, has suggested a plan to return to the Moon, which features, among other things, robotic resource extraction and the deployment of space-based fuel depots using lunar water even before the first human explorers return to the lunar surface. But Mike Wall, writing in Space.com, suggests that there are a number of legal as well as technical issues involved in setting up lunar mining operations."

ECHELON is a government program to find words like bomb, jihad, plutonium, assassinate, and anarchy.
it takes a huge amount of energy to get to the moon and then to get back
You don't have to send much material to the moon: "just" some mining and processing robots. The real trick will be getting the resulting large quantities of rocket fuel from the moon to where it would be useful (i.e. other Earth orbits). The moon's gravity well is much shallower than Earth's, but I'm not sure if it's shallow enough to make such a venture profitable.
I mean what are we going to mine that has so much value? Water? Energy production uses a huge amount of water.
Rocket fuel, apparently. But to get rocket fuel (read: hydrogen and oxygen) you have to split the mined moon-water, which means you'll need some energy source to do the splitting. Where will that energy come from? Vast solar panel arrays? Nuclear? Geothermal? (does the moon have any geothermal energy to be tapped?)
I don't care if it's 90,000 hectares. That lake was not my doing.
We would not be mining the moon for anything that would go back down the gravity well to Earth. We would be mining it for resources for space exploration and operations instead of mining Earth for them. The moon, being smaller has a much smaller cost of getting materials into orbit. If we need a sufficient amount of those materials, it becomes cheaper to ship a mining operation from Earth to the moon and then those materials to space than to ship all the materials straight from Earth. Water is the main resource people are talking about and to reach that break even point, we'd need megatons of the stuff. The only operations that might being to need that much resources from the moon would be large scale habitation or perhaps a trip to Mars. in short, out side of pure science, there will not be any need to mine the moon till there is already a great deal of activity in space at which point mining the moon will just be a cost cutting method.
What's wrong with using oil? It's working well here on Earth.
Someone flopped a steamer in the gene pool.
It would seem that the dark and light sides of the moon comprises a heat engine. For example, a tube which was placed about the pole and filled with gas, would expand in areas exposed to the sun and contract away from the sun in a continuous cycle, much like the engine that powers the Earths weather. It would this would be extensible and provide the local energy by turbine to operate some robotic process.

woo..
gonna need some specifics before I get behind this project.
No. The "dark side" of the moon always faces away from the earth. It doesn't always face away from the sun. It is fully illuminated during the "new moon" phase.
HTH. HAND.
