Lunar space elevator
There are two lunar-synchronous points where an elevator could be placed that would be stable: the Lagrange points L1 and L2. L1 on the Earth side of the Moon is 56,000 km up from the surface, and L2 on the far side is 67,000 km up. In these positions, the forces of gravity and centrifugal force are equal, and as long as the system remained balanced (L1 and L2 are in unstable equilibrium along the line between Earth and Moon), it would remain stationary.
Helium3 has a lower fusion point, and much less danger of a reaction going out of control.

For those of you interested, here is an idea from a Japanese company trying to do the same thing, but it's called a "Space Elevator", somehow saying it that way makes it seem more feasable.
I like this site very much, there is a lot of cool stuff to look at.

There is a litle more info here on how it "could" be done.
But seems imposible with todays material.

A space elevator is "feasible" with a geostationary satellite being at the terminus and the base being located on the Earth's equator. The problem is, there is no material currently available which could support its own weight. Pretty scary situation if the damned thing breaks.
An elevator to the Moon? No.
Carbon nano tubes?

also forgot to add, as far as i know, at this time, there s no known material that can withstand its own weight under gravity for the, 22,000 miles it take to reach the geosync sat station. (obviously the "tether" will only be supporting about 60 miles of its own total weight total since after it gets high enouh it will be in orbital freefall.)
carbon nano tubes are the closest analogue, and they are nowhere near the required scale to produce enough for even a 22thousand mile long tether just to geosync orbital stations. not to mention trying to make enough to go to the moon from earth orbit( more than likely, if it did exist, they would deploy it from one of the lagrange points between the earth and moon, then just onroll it and let gravity pull it down for you.)en.wikipedia.org...
