Dear Space Leaders,

     In the course of human exploration and commercialization of space,
planets and moons, there comes a time when astronauts need to recognize what
is plainly obvious; weightlessness is hazardous to the human body and causes
a severe impact on quality of life. There is a weakening of bones, weakening of
the heart, and eyeballs becoming out of round.  The quality of life impact is
severe. Eating and drinking food is done from tubes instead of from an open
plate or bowl, and no open cups nor glasses to drink from. There is no open
shower to bathe. Going to the toilet becomes a high-tech adventure at best
and a catastrophie at worst when things like toilet paper float away. Extremely
high cost solutions like the $50,000 toilets are one remedy. It's time to break
from the fascination and exuberance of weightless somersaults and spinning balls
of water and get on with the colonization of space in permanent space colonies
with gravity.

     The trivial solution that somehow has escaped Science is to create
artificial gravity with a rotating space station. There is no need to go to
extremes and design a multi-trillion dollar O'Neal Cylinder when there is
a simple solution. The Easy-Button is to deploy the lightweight round tube
like a bicycle tire scaled up and spinning. It is made of kevlar or graphene
or similar for strength and constant radius. A central tube crosses the
diameter to the central docking hub where the entrance and exits are and
non-rotating for easy docking. It should be designed so tubes can be stacked
side by side and interconnect doorways between them. The danger of meteor
impacts is solved by interior air-bags layer that are sucked to the hole where
air escapes, sealing the hole automatically. Dynamic balance is achieved by
pumping water around to adjust for the mass of humans and equipment moving
about.

     The selling point for visitors is a space vacation that even their
children can join in. Only the transit to and from the station needs to be
weightless. On the station the person can experience weightlessness in the
central hub room for small periods of time and quickly return to 1-Gravity if
they become nauseaus or hungry or need a break. Scientists can perform their
experiments in the weightless lab and they can quickly return to 1-G.
Then they all return to 1-G for meals, bathroom, sleeping or other activities
that are best done in 1-G to retain their health and quality of life.


     The cost of this artificial gravity space station should be paid for by
the hotel and theme-park industry as they can own and lease real estate in
such stations for hotels and villas in space. A business can pay for the
station and then lease property in it to hotels and theme parks. A hotel chain
can own the entire station. A theme park can own an entire station. All the
amenities one expects in a vacation can be put the 1-G station from restaurants,
bars, cafes, chains, stores, shops. There can even be recreation sports like
fishing in a stream with water pumped from the low area up to an elevated place
to flow downstream again.

     A competition can be started to see who can design the most functional
and yet cost-effective Artificial Gravity Station with prizes for 1st, 2nd
and 3rd and honorable mentions. The design must be realized before the prize
is chosen to separate Theoretical from Applied.

     The Intractable Studies Institute is available to consult on any
intractable problems that need solving in the Artificial Gravity Station (AGS)
habitat and colonies. Other less than intractable challenges can be solved
by ordinary companies and research entities. The Institute prefers to work
exclusively on intractable challenges, that is our Mission.

                       Let the AGS Space Race begin!


Sincerely,
