Abstracts for SE2107
Work in progress, waiting for the submission system to be set up. I will keep updating the abstracts, and add papers and illustrations as they are written.
abstract: Acoustic Elevator
Vibration power in the stiff tether itself can provide megawatts of power to arrays of small, redundant, failsafe and adaptive cammed motors, which can lift 14 tonnes of payload off the surface at 140 meters per second.
Some 2-weeks-outdated work here.
abstract: Launch Loop 2.0
Combining the best of the space elevator with old and new launch loop developments. Surface logistics like the space elevator. A 70 km Kevlar tether to a surface-powered electromechanical 11 km/s launcher, then a 5 hour trajectory to a rotating Kevlar capture tether in geosynchronous orbit. 15 tonnes per day with a minimum 500 MW power supply, 400 tonnes per day with a 6 GW power supply, which can be provided by space power satellites. Can be built with off-the-shelf materials.
Uses VASIMR electric rocket engines and some atmospheric argon propellant to add angular momentum at GEO.
