You'd need a *very* big station to be self-sustaining for that many
people.

Unproven.

Biosphere 2 (which didn't quite work, they had to pump in oxygen after a year
or so) was enormous and that was to support fewer than a dozen people.

B2 didn't work because far more attention was paid to ecological
mysticism than to science and engineering. I'd not use it as 'proof'
of anything one way or another.

Is there any chance that another similar project will be attempted in the
near future?

How do you propose to make food from waste without plants?

You don't need that many plants.

30 or so square meters of plant growth area per person
should do the job.

There are plenty of studies of Controlled Ecological
Life Support Systems (CELSS) done by NASA, including some
"locked the researcher in the sealed habitat with the
plants for several months" tests done back in the early
90s (and since then, on and off). No, not referring to
Biosphere-2, these were smaller scale high efficiency
NASA projects. Google on CELSS for more references than
anyone could reasonably summarize...

Not to most people. That's a new usage for an ellipsis.

New to you perhaps.



we could have just used an ellipsis...

What is an ellipsis? I've heard of an ellipse but never an ellipsis.
Are you inventing new words?

Yes, new to me. How would I know for sure to whom else it's new to?
I only know that I've never seen it used for that purpose before, and
I read (and write) a lot. Perhaps you're part of the weird minority
to whom that would have been obvious.

The three dots are not in fact an ellipsis but a curtailment of the
dotted line on forms providing space for you to put your own words or
answers.

The British temperament tends towards humour and, for instance, faced
with the question "sex..." on passport application forms is as likely
to put "not enough" as M or F. It is often advisable to think if there
may be some humour present before taking the pedantic line.

And probably not true if you have an efficient closed-loop ECLSS with at
least one or two strings of redundancy - if one string goes down for
repair or maintenance and it's the only one you got, you HAVE to use
non-regenerable means to remove CO2 and add 02 pretty quick. Water you
can store in accumulation tanks for processing after repairs or
maintenance is completed but air starts going bad fairly quickly.

But several other such studies do; further, it is the subject of LOTS of
research, studies done and re-done over and over again. That suggests a
correlation,

No. Having a lot of studies indicates a lot of interest, not a
correlation.


Studies showing correlation indicate correlation, Derek. Please read
what I wrote in the context of my reply to you, rather than what you
apparently think I wrote.

You need to take more English classes. This is an ellipsis: ...
E.g., three non-spaced periods, one following another, indicating an
incomplete thought. Also used to indicated redactions in quoted
material.

(AA Institute) made the phosphor on my monitor
glow in such a way as to indicate that:

There's this new invention called a dictionary. You might want to
familiarize yourself with it, so you don't make a fool of yourself on
Usenet. But, hey, I'll help you out. Google is your friend, too.

And note that none of the standard uses are an indication of humor,
weak or otherwise.
