Great very high def shuttle launch video sequence in slow motion.
Really good porn.........................no not THAT kind.

More Rocket Porn.....
How to reduce rocket emissions! Also, note the future use on the moon/Mars return to Earth launches.

Two or three times the narrator says that their projectile is launched at Mach 1. That's about the same as firing a .22 rifle up in the air- it doesn't even come close to orbital velocity, 18,000 mph. They think they'll achieve 10,000Gs in their centrifuge to launch rockets? With a 1,000lb projectile, the force would be 10 million pounds!
Project HARP is mentioned as one alternative that has been tried to launch projectiles- that is an interesting story. The man who designed the "superguns" was assassinated to stop his development of these guns. I can't remember the name of a book that told that story.
I'm really getting fed up with presentations that mix archived live video with computer generated graphics without identifying the parts that are only "simulations". NASA is a prime offender in doing this. People can't tell what is really true from false. I suspect this whole video is clickbait to lure investors into their hare-brained project.

The demonstration prototype that is featured in the live video is just that, a concept demonstrator. Scott states that It does work well enough to throw the test projectile in the test video to an altitude of approx 35000 feet. The development system is smaller and runs at (for now) a reduced centrifuge RPM. This is the nature of engineering development. Start with a concept, prove the concept in a limited performance envelope, improve the performance of the limited capacity prototype and then scale it up.
I find it interesting that the timing and instantaneous load compensation of the launcher seems to have been developed to at least this limited performance profile it and works. It is easy to see that more performance is needed to achieve the stated goal of eliminating the first stage of the current medium-lift systems such as the falcon X. That would be a breakthrough for the commercial launch market. Imagin Space X not needing to recover the first stage and in fact not a need for the first stage at all!
There is clearly a way to go with this concept to reach that level of performance. But remember Space X started with the hopper and that was only a very short time ago.
My immediate attention was peaked with using it for launch return missions from the moon. No need to develop fuel production on the moon, the use of very efficient solar electrical power, and the big one, a gravity well of about 17% of the earth. Comercial mining products returns from the moon could be scaled up to very inexpensive levels without the need to deliver a complicated launch system to the moon for each return mission.
Think mass-produced return containers.

Plus on the moon, you don't need a sealed system to have a vacuum.
A problem is getting the rockets to the moon in the first place, unless you design the lander to fit into the centrifuge.
The guy that made the superguns had the last name of Bull and they made a movie about him . He had been working on the gun in Canada back east and had the gun pointed at the USA. I don't remember the name of the movie but Frank Langella played Bull.

That's in reference to the demonstrator hardware. The velocity mentioned for the full size model was Mach 7 or so. I think they said up to 450 RPM with a 50m radius, but doing the math give WILD numbers as a result. I would hate to have to balance that rotor after projectile release.
Yeah. That's the part I'm having a tough time with myself. I get the benefit of accelerating it over a long time and all, but whatever they attach at the end of the swing arm will be hurling around at 10k g's. That's got to have some massive structural integrity to be swung around like that.
