Technology has always found its greatest consumer in a nation's
war and defense efforts. Since the last attempts at a "Star Wars"
defense system, has technology changed considerably enough to make
the latest Missile Defense initiatives more successful? Can such an
application of science be successful? Is a militarized space
inevitable, necessary or impossible?

"...If you could make this breakthrough in photocell cost --
reducing photocell cost several orders of magnitude from what it is
Aren't you the same Robert Showalter that argued previously that
"orders of magnitude" breakthroughs just aren't likely (when applied
to other topics)? I believe so, so I'm heartened that you seem to be
conceding the point by your present suggestion that such progress is
now not so impossible after all. Good for you! All things are
possible. This is progress!
"...Having looked some at Perlin's material, I'm not going to
consider land-based photocells further - after a century of
development, they remain much too expensive...
Umm, Robert, when these "orders of magnitude" breakthroughs of
cost improvement in polymeric solar cell material are be made, why
would the same material cost more to deploy on a nice stable desert
floor than on a hoped-for calm sea?
All your reasoning about becalmed sailors sounds pretty good
coming from sombody who has obviously never spent much time at sea!
But in high sea states waves can exceed 90 feet and rip steel off of
ships like we can rip the crust off a loaf of bread. The sea might
be calm for months at a time in certain equatorial regions, but
there is nowhere on earth that the sea is calm all the time. Did
Perlin mention that? Two things I can say for sure are that human
failure to respect the power of the sea has cost untold thousands of
lives in the past and that the sea will continue to take it's toll
on those who venure out upon it ignorant or unprepared.

The missile defence programme has indeed woken a sleeping nuke
giant... So here starts the next nuke race...
Extract from New York Times U.S. Says Russia Is Preparing Nuclear
Tests By THOM SHANKER
WASHINGTON, May 11 — Administration officials have briefed
Congress on what they described as disturbing intelligence
indicating that Russia is preparing to resume nuclear tests, even as
President Bush is scheduled to meet with President Vladimir V. Putin
of Russia to discuss arms control later this month, government
Selected members of the House and Senate met in small, closed
sessions and were told of a new analysis by the Joint Atomic Energy
Intelligence Committee, a panel that collects the views of many
federal agencies on nuclear issues.

When I looked at wind loads, turbulence, and cleaning issues -- I
couldn't make the desert case work. Maybe somebody could.
The equatorial seas looked good, so far as I got. You have
examples of 90 foot seas, near the latitude of convective center
(which varies with the season) - or even rough seas? The sea can be
cruel indeed (and being becalmed is one of the cruelties wind
sailors fear most). But the physics of weather of open sea at
latitudes very near the convective center of the earth is relatively
simple - and stable. (The convective center latitude is 0, the
equator, in the middle of the spring and fall seasons, north and
south of that at other times.

Aren't you the same Robert Showalter that argued

likely (when applied to other topics)?
It depends on the details of the topics. For particular
cases, I certainly did argue that, and for reasons of detail. How
likely are the breakthroughs? In specific cases, you can
check. MD1076 rshow55
