Casey Handmer on how Elon's Mass Driver is going to work: "With a rocket, you can launch every couple of days if you're really good. With a mass driver, you'd have a shuttle that sits in an electromagnetic track and once it starts to slow down, roughly halfway down... show more

@CJHandmer Wow, Case Handmer — huge get

Casey’s 100-ton/day example works out to about 1.16 kg per shot, using metric tons and one shot per second Getting that stream to the Moon’s 2.38 km/s escape speed takes about 3.3 MW of average kinetic power. That’s just the payload energy, before losses and shuttle cycling. Peak power during each shot is a separate problem A useful scale to put next to the daily tonnage

@CJHandmer I wonder if you can just do a belt loop for the sled so it does what a rollercoaster does when it loops over a bend, and instead of slowing down, it uses the residual velocity for the free return and the electromagnets just assist in slowing down back to launch.
