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
[banjo noises from the direction of Engineering]
"Sounds like the Engine Thrall tribe are active again. Time to leave, quickly. No, not that way. We don't go into Organics Recovery since..."
That looks very 40K on paper, but how would they get their food and water though?
@@chaptermasterpedrokantor1623 corpse-starch...... solves some of the problems.
@@chaptermasterpedrokantor1623 Raiding of course. Wars on ships that large are not just possible, they are nearly inevitable...
@@mrp782 I don't think you can feed a population on its own bodies. In it's lifetime a human consumers more then their bodyweight in food. I swear that GW takes grimdark to ridiculous extremes, Or it's the old saying, scifi writers are clueless to scale. And warfare. And logistics.
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
the defiant in startrek was one of the best personal spaceship, probably as big as a 2 bed apartment to cruise through space...awesome.
Louis Wu from Ring World does finish off with the most amazing ship in all SF. It combines Pak and Puppeteer technology.
I want to do that to my room. I want an airlock, a fake window to view space outside, and a hammock from the ceiling to get a floaty feel. IDK just me? Ok...
Wow I had no idea other people did this to fall asleep!
My two primary personal spaceships are a maxed out S-Class fighter named "Paladin" and maxed out Exotic class named "Valkyrie". They are both very formidable - when a pirate or sentinel ship sees them they usually say "wait, I'll just blow myself up". I also have an interstellar freighter attended by a host of frigates. We have visited many strange star systems.
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.
Didn't asimov sit in on nasa meetings as an ideas guy

There is a point in the future where a personal spaceship becomes cheaper than the most expensive Star Citizen spaceship.
Theoretically, that's true - but it is also a mostly meaningless statement because by that point, _EVERYTHING_ should be cheaper than the most expensive Star Citizen ship.
Nonetheless, we will find more inane ways to spend our money, and the absence of necessity only ends up making non-essentials more valuable.
It's impossible to predict whether or not we'll be spending the majority of our money on novelty Halloween masks year round as a sign of social standing in 10,000 years.
Damn, Star Citizen is like nuclear fusion
I seriously do not understand how people can spend that must on an in game asset
Freaking play Kerbal space program or no man's sky Jesus Christ

@@chistinelane Imagine that you bought some super expensive vehicle with a computer system that can be remotely turned off because you don't really own the vehicle you paid for.
"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.
Space Engineers is cool, but it's way too hardcore for me. The complexity of even the simple things that you build in that game are just so crazy that I feel like I need an actual engineering degree to properly play it.
Beyond that, the early game in survival mode is so tough and slow that me and my friends lost interest so quickly. I remember we'd get attacked so often, and that would often take us back to the stone age with no power. Mining for resources takes so long even for basic things. I'd be mining for hours, and it still wouldn't be enough for anything.
Building a ship? Hah! That's funny. No ship at all.
It was so complicated that I couldn't even get through the damn tutorial. Neither me nor my friend could.
Even in creative, I couldn't understand what the heck was going on. I couldn't actually design anything.
I like Empyrion a bit more. It's more simple, and the survival mode isn't nearly as grindy. Problem is, the simplicity is also its biggest weakness. You don't get as much creativity as you can with SE. Ships kinda just do all the same thing, just in different scales. You can't really build your own missiles or anything like that. Still, I can role play having my own giant capital ship with a hangar full of starfighters and vehicles. The game also seems to run more smoothly on my computer. The other problem with Empyrion is that the gameplay loop in survival is kinda...stale. You just go around collecting resources so that you can go around more and collect more resources. And at the time that I was playing, there wasn't that much of a universe to explore, so once you gathered everything, that was it. I hope it got better now.
The value I see in both of these games is the ship designing aspect. And being able to see other people's designs. My best design in Empyrion was a starfighter that I built by modifying somebody else's existing design. I essentially just made it more powerful in every way, and that was a great way for me to learn some of the basic design mechanics in the game.
SE is really run, 100% agree. I will say though, I spend more time planetside making mechanically complex systems than ships. I am generally bad at aesthetic design 😛
The problem with space engineers is that it’s mostly survival oriented I want to found my own business from small freighter to basically running your own nation and influencing the wider world that’s why I play x4 foundations and other games of the series unfortunately you dont get the satisfaction of designing and maintaining your own ship but you get to enjoy a full sandbox in a living breathing world without the hassle of dealing with other people like eve, elite dangerous and Star citizen. Also the deep lore is a +
Space engineers is the bees knees. Been playing that since it was available for purchase lol the only dev company that will add mistakes the community finds to the game as features (that time we had to break a small rotor inside a large rotor in order to connect large and small grids)
Theres an ingame scripting console which is unheard of in games.
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.
[THROWS DICE]
Come onnnnn, Epstein Drive!
I would personally go with a large plastic barrel and duct tape. The internal air can be released from small holes in the side by peeling back or poking through the tape providing thrust.
A Star Trek transporter would solve that problem quite neatly.
I know, the launch costs of $10,000 to $25,000 per kilo must come down!
@@ChickensAndGardening Are you talking about the small impulse drive ships or the teleportors.
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!
LITERALLY. Isaac has helped me write better genuinely
Why not a Joe-Schmoe space farmer in a rolling, private owned O'Neill Cylinder that drifts space station to space station selling and trading wares and crops for space stations orbiting ground stations-- it's long journeys fitting the time required to grow crops, ect? I see bonus points if he is growing... less-than-legal, but highly valued crops?
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!
The best you will see in your lifetime living in meta, owning nothing, with no permission to go outside and eating bugs 24/7 by the looks of where things are going.
When we can get to orbit and get around space as easy as we get around on earth. That well come when we have antimatter technologies which believe it or not could be possible in less than a decade.
It take miligrams of antimatter used as a heat source for a propelant instead of oxidizer. Oxidizer is 2/3rds of the weight. This means a ship could take off with a lift body from a air port into orbit and farther. Then if you use it in fusion it only takes micrograms. This is called antimatter catalyzed fusion. This is not my idea I got it from Omni 3 or 4 decades ago.
The thing is at the time we had no idea how to make enough antimatter now we do. A factory out in the middle of nowhere solar powered with a 2 mile track can make 2 grams per year of non specific large atom antimatter. Most of the physics of how to do this has been figured out. On the moon 6 times for the same type factory.
This is using new technologies the accelerater is only 1-1/2 foot wide. What is made now is anti hydrogen. It takes enormous amounts of energy to make cool and store. But if you make large atom antimatter like carbon and other large atoms it is a lot easier and takes a lot less energy. And you can store it for years.
@Moth Moniker If you are talking to me it would be a lot farther than that. A small spaceship with 30 miligrams of antimatter and 200 gallons of water could get to the moon. 1 gram of antimatter has 3 times the energy as the atomic bomb dropped on the Japanese. And you don't have oxidizer which is 2/3rds of the weight of the fuel and dry weight to hold it. Then if you use antimatter with fusion it takes in the micrograms that is a thousand times less antimatter.
@@clementvining2487 small scale fusion would more than do it and be much safer. And we'd probably need stupidly large scale fusion to make antimatter a cheap enough fuel source for even US military uses. At roughly $2.7 quadrillion a gram right now you could make it a thousand times cheaper than today and even then Apple and Amazon combined couldn't afford enough for a trip.
@@MechanicaMenace Dude you have no idea what you are talking about you see too much UA-cam. You talking about anti hydrogen for experiments and research. Making the right type in the right way. Then using it for a heat source for propelants the cost would compare to what it cost now to get something into orbit. What you are saying is nonsense but most people believe like you because they listen to these you tube influencers who have no idea what they are talking 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
It is actually under study, some models of dark matter use chameleon particles which change mass. I think in EVE onllne warp drives also work on the similar principle by "depleting" vacuum fluctuations.
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 😂
The crew died in the beginning and millions of years passed.
Hate this guys face, the cheap 5x5x5 feet set and the same set of jokes copied from Fawlty towers, There was no british humour before Chapman.
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.
That goes for a lot of us. Well said.
Based! I agree.
Thank you, it always makes my day when folks say something like that.
Despite the design flaw I'm a fan of the Hot Needle of Inquiry.
Niven's has a knack for fun ship designs, and names too :)
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.
Do you own the best retail telescope out there?
@@jsbrads1
Them 16 inch are upwards of $10k so no.
@@bengsynthmusic looks like they have 10 inch for $650. Also try to see if there are any groups in your area that meet on cloudless, moonless nights.
Also worth seeing entire galaxy, clear night above 8000ft.
@@jsbrads1
That's cool. I'd love to experience that. But my main comment is a lot more ambitious. I meant seeing the rings of Saturn upclose from the window of my spaceship.
@@bengsynthmusic you are better getting a wide angle view from far away. I think the planetarium has some amazing gazillion K views projected, major upgrades… for now 🤷
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!
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.
Yes, motherships are going to be huge than many people expected.
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!
Right away when I saw the title, Depeche Mode started to play in my head.
Yeah me too, its unrelated to the title but kept popping into my head when making the video
Me too. Even wrote the chorus out!
This is why I scrolled through the comments first before posting this very comment lol
Thank you for introducing me to this band!
@@revenevan11 Good 80s/90s pop band. Unique sound. Glad you caught a new thing for you!
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.
Value is relative, didn't they trade humanity the blueprints for a hyperdrive in exchange for sole ownership of Neptune's moon Triton?
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! :)
unless we crack the mystery of antigravity. Just imagine a totally silent ship that you could just slingshot into orbit because it's weightless.
Consider the space-yacht equivalent of a private rail car. You don't really need to own the whole railroad to make use of it. You might own a space-yacht the size of a rail car and hire a booster, space-tug, or a mass-driver when you are ready to change venues.
Agreed, far easier to build a Space RV that stays in space, that it would be to make a single seater spaceplane to go between surface and space.
And the space RV can give you space and resources to enjoy long trips, even if you need to meet up with the equivalent of a interplanetary Ferry to go between the planets, while using it's own engines to move between space colonies and moons
“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.
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
Indeed, I've always wanted my own Penance -- even a ST TNG-era Runabout.
i like the Delta Flyer
I always liked the saucer ship in the show.." My Faorite Martian".... building one in my garage right now. Sweet ride..

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.
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.
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.
Your own...
Personal....
Spaceship...
Something to fly to Mars, go to the stars.
Reach out and touch space!
Bowdadabow dada bowbowbowbow daaduh.
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.
I'd have extra self running generators throughout my ship and a couple of extras. So, no matter what environment or situation I get into, I can have clean energy no matter what.
I've always thought about this since I was a kid.
Thanks for covering this!
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.
That intro hits a little harder now that SLS is about to launch
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.
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.
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
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
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.
This is the only reason I care about space, engineering, futurism and sci-fi. I can't believe it's happening
With the way things are going, it almost seems like it's going to *have to* be personal enterprise that takes us to space. Governments are far more interested in maintaining their own power than they are on bettering humanity.
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.
Yeah, space elevator will be get here before personal space ships.
One time I got a call on my ship's Fatline receiver. It was old gallstone herself. "You have been chosen to go to Hyperion..." So I rendezvoused with the tree ship, thereby putting an end to my dinosaur hunt.
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.
Do you have your book posted somewhere?
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.

Always remember this was the general mindset on the things we all have in our pockets, desks, cars, wrists, etc.
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.
Spaceballs ! I wanna Upgrade my Camper 😁👍
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!
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?
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.
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!
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.
Been waiting on this one Isaac. Oh boy your show is really getting good now.
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...
I had the same experience, the game is wide as an ocean but deep as a puddle. I remember making a massive odyssey from the Bubble to Saggitarius A and Colonia during the lockdown, it was fun at first but I would never really do it again.
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.
Truly great content, Thank you!!
On my channel there are about 40 videos of a series of ion thrusters that are patented for lifting their power supplies against Earth's gravity! They are also fully verified to work. While they currently use ambient O2 as a propellant, some models have been flown with small onboard propellant cylinders, videos of that are included. With onboard SF6 as a propellant the craft most likely can achieve an acceleration rate of about 3.6g. A smaller vacuum model will soon be ready to test in our 30" vacuum chamber, so the vacuum performance and Isp can be calculated. It has been found that these air breathing ion thrusters actually do produce a wake of charged O2 molecules, and they only ionize a small mostly fixed percentage of them. The velocity of the exhaust is also proportional to the utilized voltage and geometry of the thruster. Considering these factors and others, the craft will produce significant prolonged thrust in space with very small amounts of propellant. The next step is to run some tests and measure the results.
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.
SABRE is one of the closest we've come so far, they are just working on mach 25 airframe material (top gun maverick darkstar heating) and nacelle. reaction engines are building the engine and bae are building the fighter jet butvi presume skylone spaceplane.
I love that Prometheus animation every time I see it .
This is what we should be striving towards!
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.
I've been waiting for this topic to come up, or rather, lift off
My fav theme!!!! Thanks for bringing it back!!!!
Early reporting team checking in ! Hello wonderful fans 👋. Wait that is the other awesome space channel! Love these videos!!! ❤
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!
This is the EXACT video i have been waiting for for a LOOOOONG time
The phrase "Born to late to explore the world, Born too early to explore the stars" truly applies to me. I feel the call of the infinite but an bound to this tiny mud ball :(
you give me so much as an interstellar personal escape shuttle and I will do courier work and sh until I'm driving a private O'Neill cylinder around the galactic cluster
that's the equivalent of mowing lawns until you get a bike, so tell me again about the price of tea in China. you're small-time, all of you.
@@kingmasterlord I blew up small pirate ships and ran minor cargoes until I could afford a bigger ship, then repeated the process at a larger scale. Eventually, I ended up with a fleet of fairly large ships, running my own cargo while playing the markets.
Then the economy crashed, I got sick of people following my freighter home to try and rob me, and I was faced with a bill the size of my entire petty cash fund and most of my assets to continue my lifestyle after changes to the system, so I quit in disgust.
Ahh, a fellow Escape Velocity player 😉
I live on my boat, if we were a few hundred years into the future, I would probably be living on my space craft.
love the little sneak peek at the future episodes
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.
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.
Reach out and touch space.
I’ll show myself out.
Congratulations on regular episode 365. And thanks for the channel, its a fun one to listen to.
This is perfect. As I am reading The dreaming void series and a particular detective have a nice ship with "ultradrive" for her.
Awwww yeeeahhh the upward bound theme returns!!
Thanks for playing Stellardrone, so beautiful! ❤️
🌟🤖
Bravo on 365!!!
I'm pretty sure that a practical personal space ship is going to need some kind of Clark Tech propulsion.
I got super bored listening to this, but I appreciate that you did it. Upvoted.
36:45 There was an old science fiction story about a spaceman who crashed and started to make stone age tools to make iron tools, to make modern tools, to build a spaceship, to escape.
Factorio :D
I wanted to write something like that. But I think I would limit it to putting an existing radio high enough in the atmosphere for the signal to get out 😉 #SoundingRocket
If memory serves, “Spacehounds of IPC” by E.E. “Doc” Smith. Definitely old school, the guy was trying to make his own vacuum tubes. :-)
@@cosmictreason2242 true, but he wasn’t trying to attract people from a different solar system, the guy on the ground is being searched for by a rescue party, but once his craft was on the ground with a thick electromagnetic atmosphere his cellphone type communicator can’t penetrate the atmosphere. His friends can search the entire solar system in a few days, but search the one planet he is on will take a lot longer, but a sounding rocket can not only tell them where in the system, but where on the planet too.
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.
Love your work
This is good content☺️
Sometimes I take a moment to think about how wonderful our modern world is, in terms of technology. I can travel to the other side of the planet in a matter of hours using a flying machine for only a few hundred dollars, how is that not marvelous? I hope that, when and if we get widespread interplanetary travel, someone feels that way about the world they live in.
Star Citizen is the closest ill get.
Given the reality of the UFO phenomenon…
I’d love to have one of my own.
A craft that can hover, ascend, descend, make 90° turns and travel at supersonic speeds sounds like a vehicle of the future…
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!
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 :)
wow, the animations at the beginning of the video were distractingly wrong... rocket nozzles don't "pump" like that, and cold-gas maneuvering thrusters were firing apparently randomly while the spacecraft swung about magically somehow unaffected by them...
But the rest of the video, wow. Keep up the good and thoughtful work, Isaac!
Ah yes, this is a good one
Gosh this was well done..! Mr Arthur this was really a really cool episode...! Very Fun to think about..! Thanks a million !
Electric pump rocket engines like the Rutherford engine would be perfect for this. Very small, high performance, extremely fast response time and high reliability.
Just like electric motors versus ICE engines for VTOLS
So no range and huge recharge time, got it...and the price...
@@MS-gr2nv only if you assume they are powered by batteries, instead of fusion reactors, and that batteries don't improve much in the future
@@MS-gr2nv You only need a 50 hp pump for a 50'000 hp rocket engine. The fuel has a lot more weight than the batteries.
Picture the lenght of the extension cord...oh thats my project...and it actually works to get things into orbit :-)
@@808bigisland Just use batteries.
Your Own
Personal
Spaceship
A ship that can take you there
A ship that cares
for me, it'll still be my faithful Cutlass Black, or maybe a Spirit C1 if I can afford it when it gets released.
You bring up an interesting concept with all the launches adding tons of heat to the planet. Is there any concept for how to cool down a spaceship earth? Space elevator radiators and light deflector mirrors.
I think the Millennium Falcon is call a piece of “junk” because ships are seen like RVs, where every know what a nice one looks like.
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.
An old computer game made by Ambrosia Software was what got me wanting my own ship. The game was all about flying between space ports and exploring uncharted parts of the galaxy
This reminded me of E.E. "Doc" Smith's Bergenholm inertialess drives.
Jet with integrated LOX powered by methane, perfect seals, efficient control system (pilot’s analog stick, one for radial directions, one for linear directions), collision detection etc (laser collision destruction system and maybe a plasma shield or something for avoiding asteroids (the plasma shield destroys leftover dust)), efficient nav system, efficient propulsion system, and emergency landing system.
