I’m starting a PhD at MIT in the fall studying nuclear fusion, my career goal is to start a company that builds fusion rocket engines. Love your videos!

Hopefully the first crew will make sure to double check the voice control shutoff. Nobody wants to pull a Solomon Epstien on the first flight

I just want to say, stupendous animation.

"Alright folks. That's it, we're done" I practically heard that in Cave Johnson's voice. Imagine a channel like this but everything is narrated/explained by him.

I... am so excited! Amazing writing and gorgeous animations. I am a high school student looking into aerospace engineering and astronomy for University in a couple of years, and man, the recent influx of interesting material in these fields has me excited.

A really cool type of fusion research that's going on is called Focus Fusion, and it needs to get more attention imo. It's aneutronic and only requires hydrogen and boron for the fusion process

I'm in high school, and I want to go into Nuclear Engineering and Physics and I would like to go into space to get Nuclear fuels, the future is exciting!

The fusion rocket looks like a subject zero logo from its back

Hey, Quick suggestion: I never saw your post about the second channel in my feed, i only found out about it when i scrolled back through your community posts. I suggest you leave links for it on your description so more people find it, as it's a great resource that deserves more subs :)

I have said this before, but I love your work, the effort you put in from initial research to final product is exceptional. And it clearly shows in the final resaults. I will always look forward to the next installment, all this effort is very much appreciated. Thank you.

One of my favourite channels about science on KZfaq.

Your channel is the most underrated channel of youtube. Your content is of really really great quality and you deserve more views. Just keep in mind that you have a smaller(its all relative my friend) but a super dedicated fan base. Love from a subscriber(from India) of yours and an appreciator of your good work.

I think I will use one of this thrusters to make my personal spaceship

Can't wait to see this happening now.

I liked the dramatic pause before the massive amount of animation work

I like how he doesnt dedicate any mass to the mars lander, I just imagine a astronaut inside a Falcon heavy payload faring entering the mars athmosphere at interplanetary speeds. Also $65m per flight to mars is way to cheap (SLS cries in overbudget).

Love the ship design, both cool and realistic looking

Great video as always and not only that, I love the way you take a complicated project/idea/concept and make it easy for any to understand, plus the great animation work. Looking forward to the next video👍

I just looked up your channel again today less than an hour before you dropped this. Thanks for the quality content

anyone else getting "Expanse" vibes here?

Excellent presentation and visualization! Much appreciated!👍

This is by far the best science video I’ve seen in months… congratulations, keep up the excellent work!

Now this is epic!

Thank you for all your videos!

I feel like I was watching a demonstration of the Epstein Drive in action. That lithium casing around the plasma makes me think of a fuel pellet for the drive in The Expanse.

Fusion rockets go brrrr

Thats some high level quality content my dude

So glad you're still around!

Nice! Thanks for uploading

Thanks for yet another great video.

Yeeeesss!!! I love when you drop a new vid!!! I always look forward to them.

This channel is incredible!

Sup dude love your videos bro

Keep up the great work!

It’s actually very possible to creat fusion reactions almost as efficient as DT fuel that are aneutronic, aka almost no neutrons. Also the fuel cell in the plasmids would likely be deuterized erbium. Recently nasa published a paper on this process I highly recommend anybody interested in nuclear physics should read.

2094: still waiting for the Terrestrial fusion reactor to be finished

Great video thanks for sharing!

This is soo epicc. I love your videos! :D

Woah, this video is magnificent!

I NEED you to come back to these videos now that people have made fusion technology

Totally missed that there are new videos out, and I am even a Patreon member, haha, my fault for not checking. So this is a pleasant surprise! Because SZS makes really the BEST infographics and motion graphics of all science channels!!

Brilliant.

Keep up the good work

And one more suggestion to keep posting videos on other channel. Like what you do every day with your video projects, your table setup etc. It makes your viewers to connect directly.

incredible video!

Great animation and content bro

nice maths ! However using the falcon heavy instead of the starship for mass colonization of Mars don't seems like a likely scenario

This channel is all about Quality😍😍😍😍😍❤❤❤❤

I hope to some day be able to understand this whole video. But it's still informative!

Can you please cover the latest fusion test that was done using lasers? And how much the latest test has improved since previous tests. How close are we to a stable self sustaining fusion reaction? Thanks and Cheers!

That's a really cool texh I wonder if once we have a ship yard build on orbit ion thrusters will win out I feel like fusion is just so unessercly needs to have perfect condition kinda reminds me of the nuclear explosion as thurst method awesome stuff can't wait for future space travel im currently 22 and I hope I get to see it

Craft going to Mars also need to have lateral spin for simulated gravity and with a double hull with water , sewage and other liquids held in tanks between the hulls this provides quite a bit of radiation shielding.

This channel is underrated

Amazing production value too good for KZfaq

nice vid mate.

So cool

I love these aperture science references.

I remember 12 years ago that Fusion was 12 years away seems to always be about 12 years away and now it's 23 a theme with this technology is developing

Very nice

Everybody gangsta until the fusion chamber becomes unstable

It's here baby

Well, you got a lot of the theory right ... except for the fusing to become more massive part. It's the opposite actually ... When the hydrogen reactants fuse to produce a heavier element helium, the overall mass is reduced, which is where energy is supposedly going to come from during the fusion process. e = mc^2 ... resultant helium-4, is lower in mass, by about 0.7%, than the reactants that went into creating it, which is where the energy comes from.

Have a wonderful New Year's ! / instant travel is faster ! / / thanks

Great video and animations. I have a question/thought on this proposed engine. Would it not be simpler to use deuterium-deuterium fusion, instead of using tritium-deuterium? I understand less energy is generated by deuterium only fusion, but if I'm not mistaken there would be no neutrons that are ejected from the reaction, which would avoid energy loss and damage to the engine. Additionally, tritium is enormously expensive from my understanding, deuterium, on the other hand, is considerably cheaper which could drastically reduced costs. So am I missing something hear? Why not pursue deuterium-deuterium fusion engines? Edit: But on second look, it seems that deuterium-deuterium fusion still ejects neutrons to generate helium-3, which makes my point moot, this makes me sad

Pretty insane

Woah! A blender science guy! Auto sub

Excellent video, this propulsion system would not be good for interstellar travel however because it consumes lithium. Whats needed for interstellar travel is a fission rocket that consumes only uranium or plutonium. A ship that travels at a constant 1g acceleration rate can get to Alpha Centauri in 3.6 ship/7.3 Earth years (and that includes turning the ship around half way and decelerating) or span the entire diameter of our galaxy in 12 ship/113,000 Earth years. The ship would achieve about .95% light speed after about 1 year. A 10 ton ship would need a mere 10 tons of continuous thrust. If you want to see a new fission rocket concept watch my video "liquid plutonium rocket" it also has info on the constant 1g acceleration method.

Great vid as always, love this tech that is probably going to happen in some form of fashion, just wish it got hear for me to see. fingers crossed. Curious, Issac Arthur's channel got me hooked on Orbital Loops. What is your thoughts on alternatives to getting off earth? Sky hooks are another that seem pretty neat, at least for non living cargo. This was around the time I was reading SevenEves by Neal Stephenson which seem to have some solid science in it and started my curiosity for these epic mega projects that will probably only be under a global effort and think that too is also a few generations yet to come. Another idea after we get enough production in space is building a laser highway to mars and back, would change the cost considerably and I personally see the tech being spawned from how we inevitably start dealing with Kessler Syndrome. We will have to clean up the orbit, personally i think swarm tech will pay dividend's here. cheaper, and many, i know it sounds crazy but basically we need to herd this material in some way and why not go with what we know. its like dog herding... i take that back, its like rocket sled dog herding, but i dirges. Seems to me once we get manufacturing started and start spitting out cubic meters of aluminum sheets and girders and robot welders, we can start building the containers that will allow us to start stockpiling fuel, ore, people, science, tech ect. Personally I think the insect world will give us some solid ideas on form. SevenEves 'Nats' have been running around my brain for a while now, along with their evolved counter parts in part 2. Anyone have any favorite hard science fiction for off world stories? curious, could wireless power work reliable to space side robots so they can top off while out on the hull? would free up mass for more tools or sensors. centipedes would be a pretty good platform for low to no g environments. Each segment could be standardized in some way for some slick plug and play. Another big project i know i'll never see, O'Neill Cylinder. Media shows these naked to open space, but they will probably covered the processed material after getting the metals out. Now i'm curious on what ceramics can be made, can we also make aluminum foam or how about ZBLAN, that is worth a fortune and will make the internet faster so i'm in. once we start building up there radiation will be selling point and a huge focus for many industries and the novel combined solutions a generation after we've been up there will make many of concerns look kind of silly. disclaimer: when i say i'm curious i'm just adding to my endless 'to-do' list. anyway, i'm rambling. great vid again and i would giggle and dance a jig if i lived to see the day we had some serious freight and even a few luxury liners touring the solor system. who wouldn't want to live off earth for years? I've been joking but nearly serious about covid giving me no opt out mars isolation training. I crossed a few weird moments but think i'm ready for deep space.. :D have a great night everybody, this channel makes me awe and grateful and after the last 18 months I welcome the distraction.

thx a lot, now I see the subtitle

Hi can you go a little into detail on how you do the videos? I've seen the list of used software, but couple of details on how to do what would be cool.

Electromagnetic fusion drives may give way to Gravitational wave fusion drives. If gravity wave manipulation is how UAP's are able to fly it seems that gravity waves could replace EM fields as a means to achieve fusion in these engines. Plasma could be contained using those gravity waves.

8:42 thats gotta be a NICE! trip :D

*Antimatter:* I'm about to end this guys whole career.

Is there possibility of a video using Positron Dymamics of an antimatter drive please loved the video.

This is so cool 8:45 Nice

Damn those videos are good

I think the main drawback is the power source for the magnets all the energy going to thrust is a great way to boost efficiency but that means the heat and pressure don’t contribute to the next fusion pulse right? So I the ship would probably need to use NEP to power the magnets and that will increase the overall size but with so little damage from the fusion reaction it can probably be reusable.

Beamed power propulsion is currently possible and not only beats fusion, but also antimatter Combined with proposed magnetic reconnection electric propulsion, extremely fast trips to Mars could be made. The orbiting solar powered laser stations required could perhaps be developed in a fairly short time frame.

Fusion has yet to be achieved.

Thanks

Aneutronic fusion fuels like He3 & Deuterium should do the trick

That joke at the end made me giggle. ITER is on it’s way but it will start experiments in 2040’s Makes me think how to put such a giant structure as ITER on the back of a starship? Hopefully in my lifetime I’m only 24

If you use He3 the reaction is easier to start and control and you have less radiation as if I remember correctly that reaction doesn't give off lots of neutrons.

Would have preferred to see a comparison to Starship and not falcon heavy.

So much clean energy... I wonder why this technology doesnt receive the deserved attention from people. The progress on building a functioning and cost-effective fusion reactor is so slow, yet this tech could revolutionize our world.

Brutal

The one working on this is Dr. Slough, for those interested. Been following his work for about a decade. His design, if/when it works, can also produce electrical power. Small correction for 0:34-1:01: solar panels produce power, not energy. It would take about 1.7 hours for stated 0.7 km2 of solar to produce stated 845 GJ, assuming a standard 200 W/m2 panel. Or, with average USA weather (CF=24.7%), you would need 0.00054 km2 to produce that energy within a year. Math: 845e9 J /(.7e6 m2 * 200 W/m2 * 3600 s/hr) = 1.68 hr, 845e9 J /(365 dy/yr * 24 hr/dy * 3600 s/hr * 200 W/m2 * 0.247 CF * 1e6 m2/km2)=0.000542 km2

a kugelblitz black hole would actually be the most efficient drive system, but you basically require gamma ray mirror, which I don't think are possible, but like if you can make them then you can make a kugelblitz black hole. Also you need a stupid amount of energy, but like the sun puts out a bunch of energy and you "only" need like 10% if the suns output to make a kugelblitz black hole, and if you have a gamma ray mirror you can probably make a gamma ray laser, which you also need to convert the suns energy into gamma rays because you need to focus enough energy in a little bit bigger than the plank length, which means you need the highest energy 'light' to stand a chance. bonus if you have a gamma ray mirror is that you can reflect the energy coming off the kugelblitz black hole, rather than the brute force method of blocking the gamma rays and turning them into IR which can be reflected to create thrust, also if you have near perfect gamma ray mirrors you can theoretically maintain a very high power kugelblitz black hole as the lower the mass the higher the output, but also the shorter the lifespan.

Are you not choosing matter antimatter pair engines because they are so far in left field and would be so hard to control. Because wouldn’t those be more efficient than fusion? Great video by the way.

Still watching the beginning of the video, but you guys should look for Sheared Flow Stabilized Z Pinch Fusion Propulsion 1 million ISP at 1 meandering thrust

I would LOVE to see this CG idea mated up with a Full starship (Here after SS.)? Kinda like the idea that one SS would bring the drive up and put it into a parking orbit. Then they would send up a number of fuel SS to be in waiting for the Crew SS to arrive. Then the Crew SS launches, meets up with the refueling SS allowing them to return for refilling, then the Crew SS would move and dock with the Fusion drive module before lighting the candle as it were and making the trip to Mars. Once in Mars orbit the Crew SS would detach from the Drive module and use the fuel onboard and it's chem raptors to land the SS and complete their mission. Once they are done they could then launch the Crew SS and meet up with the Drive module before making the return burn back to Earth! This would be a truly epic use of the combined tech and I could easily see the SS being able to make this much more possible. Also just a note that was overlooked in your data is that while with CURRENT operating rockets you are correct you failed to take into account that the SS has a MUCH higher payload to orbit ratio then anything currently out there PLUS will be slated to cost a fraction of the operating cost that even the Falcon Heavy currently dose.

Why is the middle engine on the falcon 9s first stage bigger than the outer ones? Only the second stage has a bigger engine bell, because its optimized for flight in vacuum. This bothered me everytime it showed up.

One item is missing in your equation. What energy is going to start the fusion reaction, the necessary magnetic field etc? Or better, where are you going to get the energy from?

Not sure about fussion but nuclear thermal engine is worse than chemical in atmosphere, which means that you still need chemical rocket. Which is most of energy needed (if you don't use fussion for lander, which is pretty unlikely).

I suggest as design an exo and autonomus structure fitting to a Starship and for space trip only no landing.

How bout black hole spaceship? Or antimatter drive or even FTL drive Any update for future videos?

One day we will look back and see how far we were from the answer to space travel

now say " I Used To Be An Adventurer Like You, Then I Took An Arrow In The Knee" lol just busting ya chops mate. great mini doc.

what about fisson fusion rockets? or hybrid. For example breaking down plutonium (high energy density) down to a fusible material.

After watching Artemis 1 recently launch going to the moon, I'll be very excited to see fusion accelerate missions to Mars.
