- Of course they couldn't. You'd get chewed out for ruining the pristine
- environment of the desert. :)
-
- And the native materials of the Sahara aren't available to make solar cells,
- for one thing...
-
- Staying alive is mickey mouse in the scheme of things. We know how to do it, and
- we have good ideas on how to make it comfortable for long-term stays.
-
- Figuring out the total number of packages needed to provide a "reproducing
- and prospering" infrastructure which can produce O2, metals, and silicon or
- GaAs for solar cells hasn't been done. I don't think anyone has done
- handwaving on it, other than in some general outlines.
-
- I'd say 8-10 years from the initial package set down to at least one and
- possibly two sun farms to beam back significant (i.e.: to make a buck) amounts
- of power, assuming a serious effort.
-
- Of course, if you want to be petty about it, it will take a couple of decades
- to power most of the earth :-)
