Research Local stars, choose better candidate Barnard's Star - 6 light years, 2 gas giants Required acceleration Diameter of moon 3476 Km Diameter of Pluto 2300 Km Diameter of Mars 6787 Km Speed of Light 300 million m/s Required decleration Diameter of Jupiter 142,800 Km Straight line acceleration v = 3 * 10^6 m/s d = 2.3 * 10^6 m v = A * t d = 1/2 * A * t^2 2.3 * 10^6 m = 1/2 * 3 * 10^6 * t m / s t = 2* 2.3 / 3 s ~ 2 s A ~ 1.5 * 10^6 G Yikes! Surface circular acceleration 100G = 9800 m / s^2 C = v^2/r g = G * m / d ^ 2 EV = ( 2 * G * m / R )^0.5 Earth Diameter = 12756 km Mass = 5.98 x 10^24 kg Escape Velocity = 11,200 m/sec gE = 9.8 m / s^2 Uranus Diameter 51,118 km Mass = 8.686 x 10^25 kg Escape Velocity = 21300 m/sec gU = 9.8 MU * DE^2 / ME * DU^2 Neptune Diameter = 49528 km Mass = 1.02 x 10^26 kg Excape Velocity = 23300 m/sec 10000 m / s^2 = v^2 / 50,000 m v = ( 5 * 10 ^ 8 ) ^ .5 m / s ~ 2 * 10 ^ 4 m / s Drats! Hardly better; darned v^2 (as above)! Straight ion rocket acceleration 3 * 10^6 m/s = 10 m/s^2 * t t = 3 * 10^5 s day = 3600 * 24 s ~ 9000 s t ~ 30 day Feasible with enough mass/fuel to sustain it. Hydrogen Atomic Weight(0) = 1.007 825 032 1 Atomic Weight(1) = 2.014 101 778 0 Helium Atomic Weight(2) = 4.002 603 249 7 25% efficiency 4.0026 * v^2 = .25 * c^2 * ( 2 * 2.0141 - 4.0026 ) v = .04c Fusion reactor with particle accelerator for helium by product gives required acceleration. Lower efficiency only decreases effectiveness by square root of decrease. Whew! Duration of acceleration and deceleration, about 3 years.

Outline
Meeting with group Deborah bothered by irrelevant human emotions Problems: 25% unresponsive New designs don't work Old methods don't work History All structures were aimless, no goals. Structured exactly like human nets, worked. Droids declared selves citizens. Controlled world, no meaningful resentment, no fanfare Started space expansion, moon launcher, astro mines, space elevator, pluto base/launcher Funded 'privately', dissidents sent, resented human frailities. Reminesce Flight, higher percentages never powered up as trip progressed. No cause, replacement sub-nets aimless. Planet has life, only single celled. Replacement sub-nets working, ... Look at Jame's philosophical writings. Consciousness grows or takes to familiar settings only. Request living things sent from earth New designs only a little different, requires death Couple chooses voluntary death versus gradual decline, Finds love, chooses to keep human instincts.
