No problem. While I was waiting, I upgraded from a 233MHz Pentium/128MB
RAM/15GB HD/Windows 98 SE machine to a 700MHz Pentium III/128MB RAM/25GB
HD/Windows 2000 Professional machine. That's why I'm now using Outlook 2000
instead of Eudora Pro -- I now have the same setup on both my home PC and the
one I use at work, which means I can now log in and work from home, saving me a
90 minute commute each way.

No, what I was intimating was that the rocks would be drawn to the Lagrange
point proper, while the colonies would be well out of the way in their halo

Oh, I see what you mean. The circular bases of the farmsat are opaque, with
light being reflected by the parabolic mirror through the cylinder wall -- same
arrangement as the colony proper, only here the Sun is "on" 24/7. If anything
inside needs a night cycle, it gets it by being enclosed or having shutters
thrown up.

The colony proper could use shutters, too, but then you couldn't create the
illusion of a transiting Sun.

In any case, particles would not reflect in the mirror and would be stopped by
the base that faces the Sun, which could be made as thick as necessary. For
that matter, it could be covered with photoelectric cells and turned into a
power source for the farmsat or even the colony proper. You could even mount
another parabolic mirror and put a full-blown solar power station on the Sunward
side of each farmsat.

That depends on what you mean by "destroy". It would take a relatively large
amount of energy to incinerate a building, a much lesser amount to set it afire,
and a good deal less to simply cook the inhabitants. You could probably ionize
the entire area to lethal degrees without even raising the temperature

As I recall, a village in Finland had to be evacuated because it was in the beam
path of a Soviet super long range radar.

There were actually two such initiatives. The first was called "Smart Rocks" --
about the size of a basketball with enough smarts to target radio transmissions.
This led to your crowbars, which were called "Brilliant Pebbles" -- they had
enough smarts to target specific frequencies and to pick up a new target after
the original one stopped trasnmitting.
