Russian military leaders have expressed concern about US plans
for a national missile defense system. Will defense technology be
limited by possibilities for a strategic imbalance? Is this just SDI
all over again?

I wonder how Senator Levin and his Michigan constituents, who
know the auto industry, regard Rumsfeld's idea of "winging it" --
deploying "missile defense" systems that have not yet even worked
satisfactorily in prototype.
You sure couldn't be that casual in automobile manufacture ---
cars are MUCH too complicated for that to be practical. Anybody who
has been near automotive design and production knows it.
And a missile defense system is much more complicated than
an automobile.
And in addition to the complexity, there are the very tight
tolerances.

In some other areas -- solar energy and global warming control,
for instance - we face large scale but simple problems. With
loose tolerances, and many different ways to proceed on many
of the technical details involved.
The estimate of all the conventional oil that there ever was or
ever will be is less than the amount of sunlight that hits the earth
in one day.http://www.oilcrisis.com/debate/oilcalcs.htm Exactly the
kind of "wing it" approach Rumsfeld just proposed for MD might
actually work for solar energy -- we need to find ways to use
very extensive areas available on earth -- and the equatorial
oceans look like a good place. For "space available" we might SOLVE
essential military and economic problems for the whole world --

The energy content of world oil consumption (70 billion
barrrels/day) could be matched, if 2.1 x 10^11 square meters of
photocell area - at 5% efficiency, could be equatiorially placed --
there's plenty of room for that in equatorial oceans (that area, in
one floating square 460 km on a side would look very small on a
map).
We could have unlimited energy -- and the engineering resources
to make that supply real seem to be available - in the form of
people and organizations, now "going wrong for want of something to
do" -- trying to make weapons that nobody really needs, and that
nobody can figure out how to make work -- where there are
simple but large scale jobs, fundamentally more important,
that could actually be done.

One of the things this thread has shown is that overt and covert
war, these days, is largely about oil . If the world had a
secure, ample, expandable supply of energy, that could not be
monopolized --then the military problems of the world -- the
problems of peace, would be much more possible to solve.
For the money people are talking about wasting on missile defense
systems that may never work -- the key problems of global warming
and energy supply might be solved.
By people and institutions available.

The key technical problem is floating thin assemblies of sheet
plastic (perhaps 30 microns thick in all, including top sheet,
bottom sheet, and bubble floatation) with very extensive
areas -- and having the assemblies stand up to wind, rain, wave, and
whale problems, on the equatorial seas.
A sloppy kind of engineering problem. Once it was solved -
getting photocells onto the top surface would be straightforward.
From there to a hydrogen based economy -- the engineering is all
doable. - And the world's energy problem would no longer be the
current "hopeless" one. Easier than Star Wars.
Actually doable. By engineers and institutions that have been
struggling with missile defense, and failing.
And more important, just in military terms, than a limited
missile defense could ever be.

Solving the CO2 problem, by growing algae, and pulling
carbon out of the biosphere on a "heavy industrial, mass production"
basis -- is about the same difficulty level problem.
Actually doable. No show stoppers at all. Just a lot of sloppy,
wide tolerance work -- the sort that engineers, given time, can be
confident that they can do.

The same engineers who, if they do honest bookeeping, have long
been absolutely sure that missile defense is barely possible, if
it is possible at all.
