A project of this scope requires an impressive array of technology and engineering. While many of our claims have not been accomplished in outer space, most have been demonstrated here on Earth. Our strategy in the development of this Habitat was to employ existing technologies adapted to the challenges of outer space.
Gravity: Without gravity the prospect of long term space habitation presents many human difficulties such as bone density loss, muscle atrophy and extensive weightlessness training. Centrifugal force causes a body within a confined rotating medium to be pushed outward like the spin cycle in a washing machine. Our habitat is very large and requires less then 1 rotation per minute to provide 1g of force outward. This means that the inhabitants will experience a force similar to that of Earths gravity throughout the rings of the habitat.
Atmosphere: On Earth about 70% of all biomass is algae and it is responsible for much of the oxygen production. This same formulas will be followed on the habitat. The Habitat will flourish with flora providing a safe and stable atmosphere. We will also employ various technologies to supplement and as failsafe to the floral bio-system.
Water: The elixir of life. The habitat stores nearly 2 years supply of water for each and every inhabitant in ballast, rad shielding and stores. This water is constantly circulated within the water system. Once again, algae are employed as our primary water treatment with many redundant processes available as failsafe such as chemical and sedimentary filtration.
Power: Our primary source of power comes from 3 nuclear power generators. These are Thorium based reactors which produce a higher density of power than typical Uranium reactors used today on Earth. Any one reactor will be sufficient to provide all of the habitat power needs with the other two as failsafe. A reactor that is out of control can be ejected from the habitat. Core material can also be ejected to vacuum diluting it to the point where fission can no longer transpire. There will also be extensive solar arrays as a secondary source of power.
Radiation Shielding: The habitat is designed as a double tube structure. Each tube provides an inner and outer "skin" of steel sheathing the structural materials. These steel skins provide almost 15cm of steel between the harmful radiation and the inhabitants. Also, there is a minimum of 9metres of water contained within the hulls further adding to the radiation protection. A 1metre thick micro-meteor impact protection layer consisting of materials efficient at force distribution, such as Kevlar. There is also a layer of Thorium on the outer surface of the habitat as a neutron capture and to prep the Thorium for use as nuclear fuel. This will provide us with an excess of 55 halving thicknesses. The habitat is also equipped with a magnetic field generator that can be increased in intensity during solar flareups.
