Peter says that we can avoid the problem of storing solar power 
for a moonbase during the 14 day night by placing the collector
at one of the poles. this has two problems. First, it necessitates
long power lines if we want our base to be anywhere but near the 
pole, which is not necessarily serious. Secondly, and more 
importantly, this then leaves us in the dark for the moon's `winter'
which I seem to recall is 6 months long. Not really a useful 
suggestion, then. 

Storing heat in the ground is a little better, but i suspect that 
the heat would diffuse away into the ground or radiate away (3 degrees
K heat sink, remember) too fast for this to be much of a help, as well.

If I am wrong, please tell me, as I would like to see a way around
the problem, but I haven't been able to see one.

	I don't think that the heat from the ground will escape fast IF
You use insulation, or even just leave it. The moon is after all the
biggest example of a dewer flask...

PS      I didn't know that the moon had a 'winter'.
