Some major revisions....

The use of thin walled cylinders made of aluminum alloy 2024-T3 reduced the Habitat Sphere mass to just 8.2 million tonnes. This affects everything from propulsive energy to heat transfer. Starship Generations will now require just 51 tonnes of antiprotons for acceleration and deceleration to Alpha Centauri, cruising at 1500 km/sec during the 800 year journey. In addition the use of waste heat from agriculture and air-conditioning in the form of a photon rocket will push the starship even faster, saving over 80 years in travel time - therefore the starship will arrive at Alpha Centauri more than 3 generations sooner !

Over the past few months of continuous development & revision Starship Generations has been reduced in size by 75 percent and reduced in mass by 83 percent. At the same time its antimatter propellent requirement has been reduced by 98 percent, and the mission has been shortened by 3 generations. This took some creativeness to achieve for sure. In the future with the use of more sophisticated analysis I can only imagine how much better the ship's performance could get.
