Finished Platinum Moon

Not much to add to what I have already written.  One thing though.  Everything I
have written on this subject is in that book.  But, until I started reading up on
this stuff, I didn't know much of any of it.  What I am saying here, is if you want
to know what's the basic story in this book, all you have to do is read all the
space stuff posts.  It isn't exactly the same, but the general themes are there.
And that's about it.

This doesn't mean the end of these type of posts, though.

I have written before about wet workshop or dry workshop- terms that describe
the remodeling of the interior of a rocket after it has expended its fuel, and
while it is already in space.  With respect to the external tank that the new
Direct launcher will use, lets find a way to utilize that- don't throw it away.

There should be missions which practice this technique in space.  For example,
refashion the big fuel tanks into smaller tanks.  Then you could use these smaller
tanks and also free up some space inside the big external tank for other uses.  You
could also reuse the rocket motor.  A refueling module could refill the newly
fashioned tanks which would be connected to the rocket motor.  Then you'll have more
mission capability than before.


Update:

How could smaller tanks, which used the matter derived from larger tanks, be made
in space?  Being no expert in these matters, and just speculating, here's a scenario:

Cut the large tanks into manageable pieces.  Using molds brought from Earth and
a metal press, stamp out halves of a tank.  Then weld the halves together to make
a full tank.  The metal may need to be heated up so it will be soft and pliable
and will stamp easily into the mold.

Given that the original tanks are very large, plenty of metal is available.  Many
smaller tanks could be made in such a fashion.

Refilling a small tank should be easier than refilling a fricking huge one.  By
making a lot of small tanks, you ease a logistical problem of how to refuel in
space.
