Not until we achieve some major breakthroughs in propulsion -- exotic
stuff like antigravity, free energy, etc.

Funny enough I had a dream last night that I was arguing with someone about
the amount of information in a shuttle SRB vs. an oak tree the same size.
We determined an oak tree had similar energy content and could be grown for
like a $1.00. *The problem was trying to release the energy that quickly.

A poem lovely as a Solid Rocket Booster!!!!!"

Somehow I think something is lost in that. Also, too bad SRBs can't
replace themselves. The damn things require lots of TLC to fly again.

So there's a breakthrough waiting to happen. :-)

Better to have all the trees back in exchange for the lousy newspapers
we gotten from them.

Seriously, I don't think we quite need that level of breakthrough, I think
we can do it with less exotic propulsion methods. But it's not happening
anytime soon.

OTW, the expenses of supporting colonies on the Moon and Mars would be
prohibitive.

Think of Antarctic research times 100.

And that's a LOW end estimate.
