Great video! I thought I knew so much about ways to get to orbit, but I had never heard of CLGG, or a spin based low orbit tether system to launch things to orbit. Enjoyed the video, it was really interesting

How long would it take to develop a space gun / tether system compared to a new heavy lift vehicle? I briefly mention Project Babylon in the video, and though the launcher itself was destroyed several parts which never made it into the country are on display at the Royal Armouries Museum. *Sources:* SHARP documentation pwg.gsfc.nasa.gov/stargaze/SSHARP.htm History and Events Toolis, Kevin (August 26, 1990).

Disappointment here for me in what I thought would be the first YT video detailing the career of John Hunter, father of SHARP, and Gerald Bull of HARP. (SHARP, Super High Altitude Research Project.) At least Hunter was pictured and the SHARP gun diagrammed, but most of the video turned out to be on this concept of a 'sky hook,' not the CLGG as titled. The video suggests that Gerald Bull came after Dr. Hunter, that Bull's Iraq Project Babylon was trying to catch up to Hunter and his CLGG at LLL. Bull pioneered the gun to orbit concept long before Hunter. Bull's use of direct propulsion using smokless powder would limit velocity to about two km/sec (the velocity at which the first stage of many rockets would burn out) so Bull's projectile would need a second stage rocket to get into LEO. Hunter's use of H2 would not need a second stage since the gas could kick the satellite up to 8 km/sec. Only small rockets to taylor the orbit would be needed. So if Hunter's concepts for injector LGGs and the Quicklaunch Company were funded, there would be little need for skyhooks. But no detail of these guns was dwelt upon here. The video is correct in asserting that without a precedent of success, capital will not flow to LGG research--so no chicken, no egg. But if a country were to pour seed money into building a facility that could shoot useful loads into space, capital would flow. Most of the mass now costing an oz of gold per kg lifted into LEO is structural material and rocket fuel--things that can easily be g-hardened. Rockets will still be used for people and other soft items (until a gun with a 300 km barrel is built). Gun launch to space will happen when some entity with the money is willing to spend the same amount Space X is to develop Starship. But the first and second stages of this launcher will stay on the ground (or mountainside) built mostly of concrete and steel, big as Hoover Dam, and as easy to access and maintain. Then the cost per kg to LEO will come down to that of a trans-pacific flight.

Keep in mind the video is a 15 minute brief on the past, current and future applications of the technology. As interesting as the history is, a complete telling will take at least an hour and I hope to eventually go there in a longer format. Since this channel focuses on the future, I was interested in presenting the idea along with more recent complimentary concepts instead of rehashing the developments at SHARP. Skyhooks have recently become experimentally viable, something neither Hunter nor Bull would have been cognizant of. Skyhooks are not necessary but they are inevitable, and if we have them we would certainly use them in conjunction with gas guns due to their flexibility.

Nice. The Jules Verne Launcher as well as Quicklaunch are things that I've always thought had a lot of potential, but unfortunately few people are willing to fund their development. The idea of combining skyhooks and light gas guns is something that I've recently been thinking about, too.

Thanks! Skyhooks are so versatile it's just a matter of time before we see some private work on them. Hopefully!

As usual great stuff. Ur style kind of reminds me of the Homemade Documentaries channel. Sometimes your diction is a little too exact(loosen up a bit), makes it more noticeable that ur reading from a script. Sorry just that small nitpick. i wanna see this channel blow up cuz u tackle some cool ideas out here. Especially love stuff concerning alternate space launch systems.

you just need to go straight up, right? ok heres the plan. 12 stages in a horizontal wheel-spoke formation that convene in a straight up verticle bore. 12 pistons compress acetelyne, setting off 1 burst disc with the autoignition, then this shoots another piston straight up the middle, compressing hydrogen in the final 13th stage, which then bursts the last disc and fires a brick sized payload. Something like an EKV, which is a brick with correctional thrusters on it. I really do believe you can make ICBM sniping work

Rather than using nukes to get an Orion-Drive spacecraft into orbit I think it could be done with some sort of space guns shooting plastic explosives to the Orion-Drive. It is similar to Myrabo's Pulsed Beam Propulsion concept where the energy source in left on the ground and sent to the spacecraft. If I was a billionair I'd be busting my money on this.

This is also similar to the idea of using a laser, microwave or relativistic particle beam to propel tiny metallic sails into a pusher-style vehicle to impart thrust. Using normal explosives would be a good way to proof the concept at small scale.

Space hooks? Are they from Siemens 😂 because they also build Siemens Lufthaken®😂🤣
