- I realize that there has been much debate concerning the seriousness of the
- science of Biosphere 2. However the problems posed are still fascinating.
- If indeed this is to be viewed as a prototype space colony then I have a
- problem with the review just posted from a crewmember.
-
- There was much made of the wide variation in sunlight causing variation of
- CO2 uptake by plants. Further we have all seen discussions of the somewhat
- uncomfortable drop in O2 level. I would presume that any space colony would
- have a reasonably abundant source of electric power (nuke or solor collectors).
- This renders the issue of variable sunlight level moot as light is one thing
- that we can easily create. Also, one would not expect the sunlight levels
- in Tuscon to be available on other planets. So the real question is: to what
- extent are the questions asked and circumstances created intended as a space
- colony prototype?
-
- Obviously, a Biosphere 2 crewmember would be the ideal respondant.

- Thanks
