@exerian asked:

do you think my crazy ass launch system could actually work?

the basic idea is to use a vacuum tube to reduce the required launch fuel to almost nothing.

build a tube, it's been a while since i did the calculations and i was like 12 at the time but iirc it's like 5 miles long and goes up the side of a mountain to improve the launch trajectory. each time you launch you vacuum all of the air out. the launch vehicle is something like a shuttle that clips into a maglev train car with something like a suction cup on one end. when you let air into the tube behind the suction cup the air filling the vacuum pushes the car forward. this is effectively the first stage of the launch and it is a zero friction stage. you're not even fighting gravity because the car is horizontal. by the time you hit the end of the tube you should be going fast enough that you can kick on a scramjet as a second stage to clear the atmosphere. then you do the usual final stage rocket engines.

have you heard of SpinLaunch?

no. no, i haven't. i guess it's off to duckduckgo for me...

well, shit. that's way better but also basically the same idea.
