SPACE CANNON!

defrogITEM: Quicklaunch wants to build a giant cannon to shoot stuff to space stations.
Now THIS is the 21st Century I signed up for.
STEP 1: HEAT IT
The gun combusts natural gas in a heat exchanger within a
chamber of hydrogen gas, heating the hydrogen to 2,600˚F and causing a 500 percent increase in pressure.
STEP 2: LET THE HYDROGEN LOOSE
Operators open the valve, and the hot, pressurized hydrogen quickly expands down the tube, pushing the payload forward.
STEP 3: TO INFINITY AND BEYOND
After speeding down the 3,300-foot-long barrel, the projectile shoots out of the gun at 13,000 mph. An iris at the end of the gun closes, capturing the hydrogen gas to use again.
Step 0, of course, is coming up with $500 million to build it.
Would it actually work? No idea. But c'mon – SPACE CANNON!
Breaking out the big guns,
This is dF
