-
- Abundant - yes, cheap - no (at least by Earth standards). It may actually
- make sense to start with fission and imported fuel (or a combination of
- fission and solar power - performing the energy-intensive tasks only
- during the day), until large power storage facilities can be brought on line.
-
- I'm in favor of establishing permanent human settlements on the moon, but I
- think there's a tendency to underplay the problems (or overplay them :-).
-
- We need vigorous technology development to make it worthwhile and affordable.
- I have a neutral opinion on whether asteroid mining should be a precursor
- to lunar settlement - I'm sure it will be important in the long run.
-
- Also, I think the lunar settlement people should place more emphasis on
- robotics and teleoperation from Earth. A few humans and a large number of
- robots should be able to do a much better job than a large number of humans
- with only a few robots.
