That is a good point, and that is what most likely will happen to my
land.

While 1 g a good way to design a ship, any engine must expend a large
amount of energy to keep at the 1 g level thrust.

Finding the equation just recently  Power (in watts) = ISP ( impulse )
* 9.8 ( g ) * N ( newtons of thrust ) / 2. Any propulsion system
would require MAMMOTH amounts of power. Heat dissipation is the limiting
factor
here.

Yep a guess at this point.

Never heard of that. More information on the rot cloud is needed here.

I got the 50 people figure from anthropological studies. 50 people
is minimum number in a family-tribe-group. Also a generation is about 33
years. (baby ->adult ->grandmother). The settling of the pacific ocean
may provide a good exploration model.

  Hydrophobic gardening, and some rabbits,birds,cats,dogs
and fish as well as pussy willows and algae ( for water filtering ) and
some 
dwarf trees. Miniature pigs,cows,sheep, horses optional. Some animals
may need to be genetically altered like slower breeding rabbits.

Mechanical processes would cover things handled by microbes and
buffering of environmental variables, O2 , water vapor, CO2,heat,light.

One with a lot of "organic" reminders. A small beach with real waves
and tropical plants. A mountain-top with snow. A jungle hut. In deep
space a marble floor would be a very rare item. Plastic,wood,metal
would be common. Stone,clay,ceramics rare. Paper and ink and fiber
would be a scarcer commodity than currently available. Money would
not be not all computer funds but some other "Hard" currency. Historical
products would command a high value.

 Nope, but I do know they say it failed because microbes in the soil
kept using up all the O2 and they had to bring in more O2.

They import all the food, dump waste into the ocean and NEVER permit
woman on board.

No not at this time,but hydroponics is well understood. It is the food

Nope.  Study a email virus that kills your hard drive and substitute

My problem is that every time I design something  with part XYZ, they
stopped making that part 3 years earlier. While I can never produce
the chip, there is some interesting "free" semi-custom chip software
(linux)
at :
 http://cobalt.et.tudelft.nl/software/ocean/
---- <clip>
  + Available for free, including all source code.
   + Short learning curve making it suitable for student design courses.
   + Hierarchical (full-custom-like) layout style on sea-of-gates.
   + Powerful tools for placement, routing, simulation and extraction.
   + Any combination of automatic and interactive manual layout.
   + OCEAN can handle even the largest designs.
   + Running on popular HP, Sun and 386/486/Pentium PC machines, easy 
     installation.
   + Includes three sea-of-gates images with libraries and a
     200.000 transistor sea-of-gates chip.

It is hard to focus on space resources, when there is no orbital
delivery system yet.  $25 lb payload cost would be nice, not $25,000.
