Human Behavior in Space

From: tntucker@... [mailto:tntucker@...]

I think that water would be preferable to slag, especially since it
provides natural shielding from UV and provides soft light for plants
as well as humans.

I think O'Neill proposed slag (and then using mirrors to reflect in
sunlight) because the assumed raw material base was the moon, which is very
deficient in hydrogen. Savage assumes a space launcher so efficient and
inexpensive that hauling up the hydrogen for that much water from Earth will
be economical. Maybe.

I think any glass wall would filter out the UV, though. The cosmic ray
particles are what we mostly have to worry about.
