Adam Savage Reacts to Hacksmith's Newest Lightsaber!

Adam welcomes James Hobson -- aka the @thehacksmith -- to the cave while he's in town for the Open Sauce convention, and to check out components of Hacksmith Industries' latest proto-lightsaber hilt! James walks Adam through the anatomy of the hilt that is designed to allow for a safe mix of propane and liquid oxygen to create a wieldable plasma beam. We can't wait to see the end result when they complete this project in the coming months!

I feel like there's a chance Mr Beast may be interested in sponsoring the project since he seems to have appreciated the previous iterations of the hacksmith lightsaber

[@lokithecat7225]

So, the next step is to build a half decent sound stage, so you can have Actors come out and shoot with Sabers.

[@hacksmith]

Pleasure visiting the Cave Adam! Happy to report Bogdan's fully recovered from the accident now (this was filmed a month ago). He's gonna do a react video to this video for our members to fill in any of the parts I missed for our lightsaber backers ☺ For anyone interested in learning more about the liquid oxygen lightsaber, we've got more than 20 videos over the past year on the development process for anyone whose a member on our KZbin channel, or for anyone who has bought a mini-saber from our store! You also get a challenge coin to prove you helped develop the world's first lightsaber with every purchase!

[@uwuanims]

I'm a fellow engineer, and please make no mistake. What they've done is akin a work of art. Not only does it fit all the criteria for a light saber, but it is actually blood boiling for something this complex and detailed to be compared to something as simple as a cigar torch. These people are essentially the "world's finest" in terms of lightsaber development, and if you want something better, give them a few million dollars or go find a Kyber crystal and another million and make your own.

[@Diago767]

My favorite thing about this video is the stunned expression on Adam's face about the clean room . shows he really understands how crazy that is 😆

[@Cheesepuff8]

Yeah it’s always great seeing Adam understand how impressive the thing done by the person he’s talking to is

[@VoIcanoman]

I've worked in a Class 100 clean room (with a Class 10 clean space within it*), so I know exactly how insane this accomplishment really is. Those things are expensive, both to build and maintain, but some of the most important science possible is being done within such facilities (as well as crazy engineering - my own focus was on the science stuff, but it's clear that James and Bogdan are using their facility to manufacture things that would be impossible to create in a non-clean environment). *It sounds like Hacksmith Industries built a Class 1000 clean room with a Class 100 space inside it, which is still wild.

[@plektosgaming]

And the oxygen path they took is among the "safest". They could get away with a longer and hotter flame that requires less pressure, say, with a mixture of oxygen and ozone, but it tends to spontaneously explode. And it gets worse from there, as we then get into fuels that are mixtures of fluorine and similar instead or propane. The issue really is in finding just the right combination of fuel and oxidizer. Evidently the technology in Star Wars was such that they had gas cylinders that they could just add and the ambient air itself was enough to start and fuel the reaction. (with some help - see below) These looked like what they had at the time - basically CO2 cylinders - but the understanding was that the materials science was advanced enough that 50 or 100K PSI tanks were common? lol. The reason they needed a "crystal" was because the crystals in their universe were also used as computers. Shows and movies of that era routinely used the idea of advanced civilizations using crystals for memory storage and computers. The reason was that the computer technology then was so cumbersome. An entire room to regulate what we consider to be simple engineering tasks. Memory chips were the size of a small candy bar. For not even 1K. Now you can fit more computing power than the first spacecraft inside your Apple charging cable - and it all be invisible. So you needed a small set of circuits, in essence, to regulate it all. Which is why they should absolutely eventually incorporate them, if needed. Embed it in a crystal for aesthetics, if they want? As for the "help" mentioned above, they also had power packs (essentially supercapacitors or batteries) because it's entirely possible that they were doing some sort of processing or compression of oxygen in real-time to start the whole thing off. They basically needed the fuel and the rest was handled or processed locally. Sorry, got a bit nerdy - lol - but I see them getting this amazingly close to the real thing in about 10 years.

Self sustaining as long as you don’t run out of propane and liquid oxygen… The self sustaining part is the heating of the propane… the fire coming out of the end of it heats the coils, so the propane stays hot, and doesn’t freeze from the liquid oxygen…

[@harrisonbergeron9764]

@@HettycTracyn So it's not self sustaining since it requires you to continue to feed it fuel.

@@harrisonbergeron9764 yes, the only self sustaining part is the heating of the propane

​@@harrisonbergeron9764Don't be obtuse. Anyone can see what he meant here, obviously he's not suggesting that the system will run forever when you use it. He was clearly talking about the heating and cooling system not needing anything to continue working once it's going. It's an incredible achievement and being pedantic does nothing but diminish that fact.

This is just wonderful! Thank you so much for your effort 👍🏻

When Adam is astounded…. You know you’re on another level. 😮

Thank you for the upload Adam, you've made my day.

Who needs a thermal detonator when you've got a lox lightsaber? M.A.D. in sword form!

May the Force be with you, while you're making.

He’s literally turning into Tony stark at this point. And I feel like he’s going to get a lot closer to that iron man suit once him and bogden figure out an arc reactor

This collaboration was well overdue

I am an Aerospace Engineer in Propulsion and Combustion. Can confirm. This is rocket science. Is the liquid oxygen plumbing system also regeneratively cooled before injectors? You could potentially preheat the oxygen by dumping through a electrically heated platinum wire mesh (like a dish scrubber. I am not sure what type of combustion staging you are doing but there are a few options. Also, use liquid nitrogen and bleed gaseous oxygen through a copper coil in the LN2 bath to gather the amounts you need.

So these guys decided to build a portable rocket engine but rather than being optimized for thrust it's optimized for the cool looks of the exhaust.

I'm one of the few lucky people in the world that got to operate an industrial scale LOX generation plant. You knew the danger, put it out of mind and got comfortable with the fact if something did get sparky the whole processing plant was gone in an instant.

Arceus help us if this thing gets perfected and built, then ends up in the hands of people who can't figure out how to tell the difference between "The Force" and "The Schwartz"...

That amazed face on Adam at the beginning was absolutely priceless. Can’t say he’s been that astounded in a while.
