My favorite lore about 40k is the ships are so big theres literally cult civilizations living in the corners of the ships that havent been seen in thousands of years

There is a point in the future where a personal spaceship becomes cheaper than the most expensive Star Citizen spaceship.

Imagining myself in a personal deep space vessel is how i get to sleep on rough nights so this episode is right up my alley

If I were the richest man in the world, I would not hesitate to HIRE THIS MAN FOR MY R&D. I swear, Issac could consult on the greatest projects of all time.

"A ship with an inertial mass changer" This is literally the titular mass effect from Mass Effect, Isaac!

having a personal ship is part of the reason I love spaceengineers so much. you can make your own ship. If I had a genie one of my wishes would have to be getting a fleet of all of my ship designs.

Ohhhh this is gonna be so good for my sci-fi writing. Proving yourself the greatest source of science fiction writing inspiration on the internet once more, I see!

A space only space ship is quite affordable considering you could have the literal equivalent of a stick with motors and seats on it. It's the Earth to orbit that is the deal breaker for the pickup truck spaceship equivalent.

Space Exploration, being a science fiction nerd, is most certainly one of my dreams to see to in my lifetime. What a cool idea to go into detail about!

When discussing the Clark Tech inertial modifier, then referencing how it would be interesting in a game I instantly thought of Mass Effect, lol. Even back then I found the idea of modifiable mass to be fascinating

Despite the design flaw I'm a fan of the Hot Needle of Inquiry.

I already have a very nice Space Ship, thank you very much. Should be happy that the rest of you are allowed to use it too!

I always liked the saucer ship in the show.." My Faorite Martian".... building one in my garage right now. Sweet ride.. 👽

Hey. I just want to say I've been watching you since almost the beginning and I want to say you've changed my life and inspired me. Thank you for being you.

You forgot the JMC ship Red Dwarf, huge ship with crew of one human, a human hologram, an evolved cat, a humanoid android, several service scutters and a senile ships computer… and on occasion Ace Rimmer… what a guy 😂

This is one of those topics I'd never have voted for and yet, as you always do, every topic and every episode is always amazing. Well done and much love.

Your channel is the main reason i exercice my english comprehension. So much quality content, by far my best source of inspiration when i want to dream/daydream/writer. Has a deep introvert, what woundn't give to have my own mobile little universe to explore the greater universe! One of my funniest mental projection experience was with Elite Dangerous, a fan to simulate ac, and a mod to add vocal commands, answers, facts about astronomy, or just for interaction (Astra+quotes from GlaDos and others). Great moments!

i was binged watching some of your older episodes and had the thought of - an episode that was a list of concepts you have covered in order of how easy they would be to accomplish from easiest to hardest to not currently possible i know, add that to the huge and growing list of ideas yet to be made

Right away when I saw the title, Depeche Mode started to play in my head.

“Red Giant” by Stellardrone is one of my favorite songs. I might listen to it twice or three times a day. Issac, I want you to know that a significant portion of the music that I listen to is comprised of songs that I first heard right here on SFIA. Thank You so much for personally taking the time to pick them out and share them with us.

That intro hits a little harder now that SLS is about to launch

I find that the better way to use the Tsiolkovsky equation is Mfuel+structure/Mstructure = exp(average_measured_acceleration*time / Vexhaust) Why use this form? Because you can account for gravity climbout... For example stage 1 pushing against Eoyff 1g gravity with a 2g thrust, so that actual climb is 1g, will just clear 100km Von Karman line in 143 seconds. So Mfuel/Mfuel+structure = 1 - 1/exp(2 x 9.81m/s^2 x 143s / (366s x 9.81m/s^2)) = 54% of ship is fuel! 😮 That's just to touch space! you need plenty more for orbit, but the spacetime curvature thing is the challenge. Actually, the real question here is: SLS was designed in metric (converted to steam for manufacture), the guidance software is programmed in metric (converted to steam for readouts), missions are planned in metric (converted to steam for astronaut comm). So why doesn't NASA skip an expensive step and join the rest of the metrical world? Astronauts are smart - they'll figure it out...😵‍💫 I do enjoy SFIA.

I think about this everyday. How I feel I'm born in the wrong timeline. Seeing the rings of Saturn with my own eyes? What I wouldn't give.

Going to be honest. I think interplanetary ships are going to be huge. Talking 2 cubic miles plus. Its about economy of scale. Large ship can hold all the machines needed to process asteroids, and move to the next, while having plenty of room for internal spin gravity. Because it will be mostly hollow it will at scale have less mass than a small ship so the fuel spent to move it will be FAR more effecient.

I've always thought about this since I was a kid. Thanks for covering this!

My fav theme!!!! Thanks for bringing it back!!!!

Been waiting on this one Isaac. Oh boy your show is really getting good now.

This is the EXACT video i have been waiting for for a LOOOOONG time

I liked Larry Niven's "Outsider" alien race. They traded the ultimate in high-value-per-mass products: they bought and sold important information in their interactions with other aliens. You paid the Outsiders by giving them credit within the terms of your own economy. Sometimes they earned massive amounts of credit, considering the incredible value of their information.

I've been waiting for this topic to come up, or rather, lift off

Congratulations on regular episode 365. And thanks for the channel, its a fun one to listen to.

Indeed, I've always wanted my own Penance -- even a ST TNG-era Runabout.

love the little sneak peek at the future episodes

Hi Isaac, I have been in love with your channel since I first found it a few years back. One question: You regularly mention different sci-fi literature, most of which I've never heard of before. Do you have some sort of book list of all the titles you have or would recommend?

This is what we should be striving towards!

Super inspiring as all of your series, many thanks!

Apologies if this is something you don’t want pointed out, but I have been a big fan of your channel for a few years now, and I must say your clarity in speech has improved so very much. If it’s something you’re putting effort into, I really must commend you because there’s certainly quite a change that I’ve seen!

As has been pointed out before and again today, a belter or ice ring ship doesn't need to be much more than a pressure vessel with life support and shielding, power, engines and reaction mass. That's actually not terribly more complicated than a car, a house or apartment, and would be your home away from home... I've always dreamed of a sort of hobbit hole in an asteroid or dirty chunk of ice, moving around with small delta vee burns to visit other worlds

Gosh this was well done..! Mr Arthur this was really a really cool episode...! Very Fun to think about..! Thanks a million !

Love your work

Early reporting team checking in ! Hello wonderful fans 👋. Wait that is the other awesome space channel! Love these videos!!! ❤

Thank you!

Bravo on 365!!!

Thanks for the video. Great topic!

YEEEEEEE More Isaac Arthur!

As much as I like the thought of a Millennium Falcon in my garage, private ships that fly to space =almost impossible. Private ships that fly IN space, that is trivial by comparison! :)

I often thought that a runabout from Star Trek would be just about perfect for me especially if I could drop the photon torp launchers and use the freed power to run a holosuite to help pass transit time. A great interstellar RV.

Issac, great episode, as usual! This particular show was of particular interest to me, because it aligns with many of my interests and technology development efforts. As a practicing aerospace engineer, I've had the chance to work on a number of "personal spaceship" concepts, most notably SpaceShipOne, Quickreach, Cerulean Freight Forwarding's "Kitten", and a few other more obscure prototypes. My takeaway from these efforts is that, not only are personal spaceships and spaceplanes possible, but that their development is an important element in allowing space access to those that have the desire to expand off the planet, and have the courage to try. Keep up the great work!

Owning a space station around the moon is one of my dreams. I mean, owning the moon is my dream as well, but that might take a bit longer.

This is perfect. As I am reading The dreaming void series and a particular detective have a nice ship with "ultradrive" for her.

Recently read my first Alastair Reynolds book "House of Suns"--I really enjoyed it overall. It involves characters who are about 6 million years old (sort of) making 200,000-year laps around the galaxy in their own personal spaceships. They mostly live alone on those ships and in some cases the ships are the size of cities, each with distinctive "personalities". Just an element I found particularly intriguing. Not sure how representative this book is of Reynolds' work but I'm interested in reading more

Bless the Isaac

Thanks for playing Stellardrone, so beautiful! ❤️ 🌟🤖

I think the best way to neuter the fuel problem is to build mobile He-3 or H extraction platforms, using miniaturization tech, and a design that is easily folded up and packed away inside the ship. Both elements are plentiful. Have it where it can be assembled into two different configurations, one for ground based extraction and one for deployment in gas clouds.

That's some nice M.F. CG at the beginning. I am studying animation and modeling. I need to do something like that as a practice exercise.

This is good content☺️

Awwww yeeeahhh the upward bound theme returns!!

I could imagine vast space yachts akin to those that roam Earth's oceans. Apart from cost, the largest hurdle I see is that if artificial gravity is necessary, the spaceship will have to be at least 500 meters in diameter, putting it in cruise ship territory in terms of size. Realistically, space "cars" are likely only to be feasible for travelling from one moon or spacestead (rotating space station) to another within the orbit of a single planet.

My working idea for a personal spaceship is also a spaceplane. It takes off on a normal runway, using aerodynamics and a (highly efficient) chemical-electric engine to take off. It will then start transitioning to rocket from airbreathing as it reaches a suborbital velocity. Now, it needs to be very light to get to orbit on its own--so if you fill it up with cargo and passengers, you will need either disposable boosters (which makes it longer to get up to altitude) or a tether. I'm partial to a tether. Then, once in orbit, you can then couple your personal spaceplane-yacht to a nuclear rocket of some kind for an interplanetary trip. The most complicated part of this spaceship is that it has variable geometry internals. Part of the ship then switches from the floor being the Z-axis (on a plane, the X axis is forward along its length, the Y axis comes out of the right wing, so positive Z axis is downward) to the floor being on the negative X-axis. This would make it more like the ships in the Expanse, taking advantage of efficient nuclear rockets for constant acceleration to generate gravity, perhaps on or near 1 g. These ships can have "intertial dampers" but mainly for safety which also means it can have artificial gravity, but that system consumes a lot of energy so might as well just use acceleration from blowing things out of the tailpipe.

I love that Prometheus animation every time I see it .

In Doc Smith's classic Lensman series, inertia control was the key technology for space travel. Ships would go "inertialess" and then zoom off at velocities limited only by friction with the interstellar medium. This gives a perfect justification for pointy-nosed spaceships which have to keep their engines running as they roar through space faster than light.

I've been planning to do this for years. I plan to use dielectricity though, rather than thrusters. From what I can tell so far, the materials needed would cost around 50k or so unless your slowly source it from scrap yards and recycling it yourself. (Wich is what I'm doing currently) It would mainly just be for me but I'd definitely wanna be able to accommodate at least 4 other people. My method would utilize a field abextra to the craft and its hull, and like the inside of a fusion reactor, would keep cosmic Ray's and ionized matter like solar plasma from touching it. It would be able to ascend 90° from the surface directly to space, rather than having to circumnavigate the planet and exit at an angle. The craft and its crew would experience little to no inertia during acceleration, and any object that enters the field would also loose inertia, effectively making projectiles like 20mm or 150mm seem more like spit wads and balls of paper if fired at the craft, and that's if the projectiles dont disintegrate under their own back EMF from passing into the field at such velocities. There would be no sonic boom because the inertia of the atmo around the craft would exert little to no pressure on the air that surrounds it as its displaced by the craft's hull. No thrusters, no heat shielding plates, no gigantic fuel tank. With the correct electronics, you could run it off of a car engine. I plan to use a steam engine that doubles as a heat pump to power resonant circuits wich use constructive frequency and segmented sections to make the dielectric field impulses self amplify.

Having a personal ship is a romantic ideal that I strive to make true, and I will, even if i have to struggle against the very heavens I seek to pierce.

Imagine if our universe started because some aliens in an alternate universe decided they wanted to go to the space McDonald's on the asteroid next door. On a slightly more serious note, the most interesting type of private spaceship I've seen in science fiction media (as far as out there ideas) has to be the Planet Express ship from Futurama. The whole being able to move the universe around thing is unique to say the least. If there have been other media that used the concept it doesn't seem to be all that common. For more realistic privately owned ships I actually like what they did in the anime, Planetes.

Half the fun of writing a hard sci-fi book is I get to spend weeks learning the actual science of things like this. From Metal Hydrogen Batteries, to Coriolis Suits, to Plasma Cycle Shields, half the science behind the hard sci-fi book I'm writing is based off of things I learned from this channel. I have never so quickly discovered and fell in love with a channel. I discovered it 2 months ago, and have probably already watch about a quarter the videos on this channel. Watch one, write down the important things learned, and go to the next. For example, in my hard sci Fi universe I'm writing about, the only spacecraft shield I have are called Plasma Cycle Shields. Plasma is shot out the top of a ship, and kept hovering above the hull through an electromagnet barrier, then as it reaches the bottom of the ship it is reabsorbed and reused, and cycled back up to the top. They are energy intensive, and almost exclusively used on cargo ships traveling at low relativistic speeds. Even then, the shields are only used on the front plate of the ship. The result is a shield that bounces away dust with the magnetic barrier, and burns up larger debris, adding fuel to the plasma fire. What little it doesn't stop, it's stopped by the 0.8 meter thick Tungsten, Tantalum, Hafnium carbonitride Alloy frontal plate. I found the limitations of this technology has given me very unique situations in my book, that has resulted in characters having to come up with unique and creative solutions. Add on top of this that these shields are usually powdered by the excess energy from a "Halo Drive" usage, and it results in a very unique form of shielding with limitations. Ultimately the heat of the shield is decided by the strength of the magnetic barrier. Using A0° super conductors the barrier is limited only by the amount of energy you have available, and therefore so is the heat of the shield. Without an Electromagnetic barrier the plasma is limited below the Tungsten melting point of 6,100°F.

Reach out and touch space. I’ll show myself out.

I've felt for a while now that it's basically a foregone conclusion that I will own my own spaceship one day. I've even started planning some of its features.

Fascinating! Another phenomenal discussion! This gets me thinking - what might an “air traffic control” facility but for space look and operate like if such orbital facility were to manage hundreds or thousands of civilian and government operators going to and from earth? Traffic jams leaving earth? Much to ponder in that regard!

Izaak you liar. Watching for a year huh? I've watched all you got in mere days. It's so great and interesting it would be a torture to watch only one episode a day :P Keep up the good work :)

This reminded me of E.E. "Doc" Smith's Bergenholm inertialess drives.

Spaceballs ! I wanna Upgrade my Camper 😁👍

Thank you for the episode list. Lots to mine there for a potential SciFi writer...

Personal spaceships makes me think of Troblum from the Void series by Peter F Hamilton. His ship Melanie's Redemption with it's Ultradrive was awesome!

Super!

A Revelation Space-mention

365 Weekly Episodes, Congrats

This is the only reason I care about space, engineering, futurism and sci-fi. I can't believe it's happening

I wish I had a spaceship! This would be useful

Great short story by Alastair Reynolds called Minla's Flowers. a single manned spaceship very good.... Isaac your stuff is brilliant as always

Basically, because of costs, owners of starships will be relatively as abundant as current owners of naval ships. Small crafts might be common, but as you go bigger, only the wealthiest will have them.

One of the reasons I love star citizen is that I can live out my fantasy of owning and piloting (with a HoTaS setup) a spaceship and fly it around a solar system with planets moons and space stations.

I got super bored listening to this, but I appreciate that you did it. Upvoted.

The bedroom level of my personal space-yacht has 7 doors labeled for the days of the week. Reaction mass and exhaust velocity is not a big concern because we use teleporting to move from venue to venue in virtual reality. The yacht's primary "mover" is an array of computers that support the additional virtual reality created when our spaceship teleports onto an existing virtual reality "island". This is an economy where the primary commodity is Tessellation. Artists make a very good living creating islands that are worth visiting. Synthetic personalities provide the entertainment that tourists crave. Some professional tourists also volunteer their talents by being 'good company' for other tourists. Small-talk, banter, and singing are important interpersonal skills.

brilliant

for me, it'll still be my faithful Cutlass Black, or maybe a Spirit C1 if I can afford it when it gets released.

Issac Arthur = The edge of Imagination

I loved Elite Dangerous for a while- I mainly went out exploring star systems, flying to planets and gas giants to look at them up close... It's a really beautiful game. But everything feeling so dead in it kind of dragged me away from it. Of course, space is vast... but even Space Stations, Outposts, Planetary Bases... everything lacking any feeling of "this place is alive" ... The most depressing thing in my opinion was going exploring the universe for a month (real time = ingame time) and comming back to a station where you see maybe 5-7 ships and an announcer (sometimes robotic) that says "Permission granted, clear to land at Pad 1-4" or, personally I had an alright reputation with the federation back then, one or two Space stations said "You're clear to land at Pad Nr.-Nr., welcome home commander." That's probably the most "alive" the game felt...

Star Citizen is the closest ill get.

Now my Thursday can begin.

I am not really interested in actually owning a spacecraft until we reach the humming-glow/anti-gravity/forcefield/wookie co-pilot phase of technology. Entering and leaving planetary gravity wells by riding on top of a slow bomb just seems like something the wise explorer would try to do as little as possible. I think.

As someone who just got an offer letter to work on Jet Engines with United Airlines, I really do hope Space Travel and Ships become cheap enough to be a pretty trivial thing. 😄 Would be cool working on them and seeing regs and stuff come about as they evolve. A most informative episode as always Isaac and team.

Your own... Personal.... Spaceship... Something to fly to Mars, go to the stars. Reach out and touch space! Bowdadabow dada bowbowbowbow daaduh.

I really wish Brilliant had a full trial, I am low on funds until next month but love learning and wanted to boost my computer science knowledge. The ad at the end always hurts my soul a little bit since I'm not able to get it right now.

Congrats on E365!

Ah yes, this is a good one

👍 well done Sir. Magnificent and intriguing. Everytime.

As a child when I first learned of ram jets, I would imagine the inner surface being mirrored and lasers being fired in to bounce around to heat the air instead of combustion. I also imagined the laser beams would be structured to be of greatest density away from the walls and would be enough to form a plasma which would then be contained away from the walls by electro-magnetism, I had also imaginef a broad electromagnetic funnel to collect the hydrogen nucei found in space to feed the engine and I wrote a short story on that (I hadn't heard of the Bussard ramjet at that time). I would also imagine being able to close off the intake and feed in some other propellent once the altitude was too high for the engines to work. Now more recent imaginations involved cube sats being able to create 3d printers in space and building something like a Stanford Torus using asteroid regolith and some form of plastic binder made from the carbon dioxide of dry ice and the hydrogen in water and build the internal rotating pressure vessel out of knitting wire cables into the general shape and sealing it with thermite, oxides and or the plastics, I would then imagine centrifugal thorium liquid salt breeder reactors being made and a landing craft that could receive power via a large circular antenna (a flying saucer) from the Stanford torus like habitat, using the the water, ammonia as most water in space are ammonia water, carbon dioxide and or oxygen from rocks as propellent heated by the beamed energy and have this saucer land to pick me up, refueling the propellent by liquefying air while on the ground. I also imagined the landing vehicle made of carbon nanotube aerogel made in the vacuum of space and sealed in small cells with graphene and or oxides so that the entire structure could have near neutral buoyancy or even act as a lighter than air craft so much of the altitude could be gained with minimal thrust. Personal space crafts will become a reality and may even be built of wood and fibreglass in space habitats like the O'Neill cylinder. It is the landing and ground launch craft that would be difficult as would be the construction of the first large space habitat with minimum refined materials and labour (however 95% of the mass of a Stanford Torus is the shielding material and if it doesn't rotate with the pressure vessel then regolith bound with synthetic plastics 3d printed out would be enough, wires is also easy to fabricate and knitting can be automated with spool knitting devices, thermite is just a powder that can be ignited in space to weld the knitted structure together to close the gaps and both oxides and plastics could also be sintered on to close the gaps). Where would the air for the space habitat come from, you might ask. Again water in asteroids and space in general are ammonia water so the habitat can be filled with some water, spin gravity would slowly allow an ammonia/hydrogen atmosphere to develop, electric arcs and or laser light could help disassociate the nitrogen and hydrogen of the ammonia which would also separate in the spin gravity. The excess hydrogen could be vented from the inner surface of the spinning habitat or stored, the excess water could also be "vented" from the outer rim or stored (it could join the shielding material as ice). Then CO₂ from dry ice could be introduced and either be disassociated by the electric arcs and lasers used with the ammonia or by photosynthesis via something like algae and then you would have a nitrogen oxygen atmosphere, some water that wasn't disposed of and the beginnings of soil with the carbon though you would have to ground down/tumble to weather some regolith to use as a filler and for the minerals plants would need and of course have some fungi and microbes process it into fertile soil as well as use some water to remove the more harmful salts and chemicals from the regolith.

Just started this episode but already just need to say... Cowboy Bebop! One of my favorite "dystopian future" style depictions of things like this. Advanced space age tech in a post apocalyptic wild west style existence.

You start by buying a general products no.2 hull and then customize it.
