We need to keep an ion this technology. It is the way of the future.
Morgan H - ‘I’ see what you did there...
Are you positive?
I don’t understand. Anybody care to explain the joke?
Mfer stole my sense of humor...
NafiuGamer “We’ll have to keep an eye on this technology” = “We’ll have to keep an ion this technology”
The thought that in the future we could be launching probes that will catch up with an overtake probes that have already been launched as I type this is such a fascinating idea!
It's bound to happen!
Birkeland currents perhaps?
Joe Scott I agree! I’ve completely forgotten the name of the idea that sometimes it might even be better to wait for technology to catch up to ideas before launching probes etc because of this
Otis Getman oh Birkeland currents are cool! Just looked it up after you mentioned it. Are you suggesting we utilise them?
David Adams IF we manage to do that it would be an insanely cool achievement! And you’re right - it would demonstrate that space technology is still improving at an incredible rate!
Ion drive + Lockheed Martin compact fusion reactor = interstellar travel.
Every now and then I open this video again just to hear Joe pronoucing my name in a funny english way at 09:39
If it’s Monday, it’s answers with Joe.
Making Mondays that little bit better :)
I do what I can.
Traditional ion drives are pretty cool, but the X3 engine seems really promising
Let's get that sumbitch in space!
Awesome way to commute to work!
You do a great job at making things simple enough to understand, but not TOO simple and leaving me with tons of questions.
As always love your stuff. IMHO......When your viewers end up with more questions in their heads at the end of your presentations than they had when they started watching.......you are doing it right. Joe you are doing it right. Thanks for helping us wonder, question, and dream. Ideas are a great thing to have.
I appreciate that. And I like to make people ask questions, though I wonder if I should change the name of the channel to Questions with Joe.
I'm sure that what motivates him. For him this is more propulsion then Xenon !
This channel is really underrated... Damn, I'm hooked on every subject you talk about for the past few days... I honestly hope you can keep finding joy in what you do! Good show old chap, good show!
Yet again another fantastic episode! Thank you Joe 👍
videos are getting better and better! well done Joe!
Good explanation
Hey joe, i recently have become borderline addicted to your videos.. Just wanted to say thanks for the great work
This is *awesome*
Another great video Joe
I got audible this year, it's amazing. Just as amazing as this channel :)
Just started watching your channel like a week ago, I absolutely love just about every video I see if I had more time in my day I'd be watching all of these😂
I kinda love Audible - good addition.
Noooice!!! Ty! Great subject! Great presenter!
I love audiobooks. Great for the commute!
I'm curious, will the Columbo mission start to leave Mercury & then stop, turn around & say "there's something I don't get here. . . ."
That reference probably flew over the heads of many of your younger viewers lol
Yes. And it will have an eye that looks off to the right a little bit. ;)
Oh, just one more thing..
Yep. Straight over my gen y brain. But I’m going to figure it out.
I now know. But I don’t think I’ll be sitting down to watch an episode. Probably good tv in its day.
DesertratNT - It's still worth a watch. Columbo is a classic character.
Excellent must-read recommendation! Definitely downloading that from audible.com!
Yes keep it going !
Only on this channel do I have to spend my day contemplating ‘which is my favourite Ion drive?’
Great work Joe- keep it up:)
Joe where you’ve been for all these years that i did not know your channel, now your channel is my favorite channel i like the topics that you choose (space, technology ...) you’re awesome, the animation is awesome you provide valuable informations with somewhat deep understanding sometimes i feel alone in this world where most people are stuck in a rat race and don’t care too much about life they just live the day after day without really asking questions that matter.
I say we use all of the major ideas at once. Solar Wind, Ion, and thrusts. We can also use Solar Panels to feed the Ion more juice. Do this while using planets gravity as sling shots. I think we should come up with a heat resistant shielding and use the SUN as a sling shot. Maybe have the ship fold into a ball of heat resistant shielding and then unfold when the temperature is safe, then use the solar panels and Solar wind. Imagine how much juice the Solar Panels can collect when its as close to the sun as Mercury.
This is already exactly how ion engines work. Get electricity (electrons) from the Sun, use it to make the ions push away. A lot more efficient than combustion engines that rely on combustion product molecules bouncing off each other and guiding them in some general direction with an engine bell.
Yeah its pretty amazing.
Another awesome video, man! :D
Awesome video! Would you mind doing a video on the Parker Solar Probe that just launched?
That “hare nor there” line. Classic. Really did laugh out loud.
could you explain this line for non-native english speakers?
It is a terrible pun. There's an English phrase, "That's neither here nor there." It basically means "That's not the point." I used "hare" instead of "here". And anybody who laughs at it should really be ashamed. ;)
Wow man... from a creator (and amazingly not-terrible filmmaker) standpoint I am totally loving the tie-back to the tortoise and the hare reference at the end of the video. Very well done sir.
Notification squad
Thanks! 🍌🍌🍌
probably the first audible ad that makes me really want to use the trial.
You ever done anything on the Alcubierre drive? Love the show by the way
I'm just here for the priceless expressions.
I am looking forward to seeing how effective the VASIMR engine is. I first found out about it back around 2006 and have been keeping a close eye on it ever since.
Love the science-based vids 👍
Thanks!
Nice to see standard broadcast is getting you some fresh sponsors.
I love Audible listening to Life 3.0 by Max Tegmark it’s brilliant well worth a listen
Love the shirt man!
I love your channel it is awesome
I learn things on your channel........love from stoke on trent England :)
I am a fan of the hare. They are fluffy and adorable, and they do a binky when they are happy.
Your videos are so awesome that I keep jumping from one to another without leaving a like. I'm sorry.
This does give some interesting information about Ion Drives. Ion Drives do seem to have some potential for improving Space exploration.
Love your videos (:
Could you do a video on Neutrinos? There is some interesting stuff about the cosmic neutrino background radiation. I don't really understand why they dont interact or how they are created. Awesome vid once again btw!
Holy fudgebuckets! I JUST watched a video of yours and it said 299K subscribers, and now it says 300K!!! I was LITERALLY watching you when it happened! Good show, ole chap. ; )
Do a video on the magneto-plasma dynamic thruster.
I’ve been waiting for a review of Chaing
.Diaz ad astra plasma drive. Sorry about the abrupt ending of my first post.
Awesome video love your work, so if u built a very big ion drive compared to u size of the probe in theory u should be able to reach even greater speeds? Thanks.
You got a like for that laugh track
New video!! Whooo hooo!
Hi Joe love your videos :)
Thanks!
I recently found your channel and absolutely love it, funny, educational, great editing, interesting content and you’re fekking gorgeous 😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗
I was going to suggest this as a topic a week ago.
Plasma Thunder! Yay!
Hey Joe! Love your videos and what you are doing to promote science.
In your absolute truth video you said that all the eye does is focus the light on the retina, and that you really see with your brain.
However, image processing begins in the retina and the retinal cells are in fact brain cells that have escaped your skull.
You should totally do a video on perception and how the eye and brain create the world we think we see.
Keep up the good work!
Do a video on what happens to the brain or nerves during a brain freeze please
Looking good, Joe.
Could you do a video on Torch drives?
Ones with high specific impuls AND high exaustvelocety?
Like Project Orion, Zubens saltwaterdrive or fusion-trochdrives?
For some reason I think it's cool how similar the ion thruster diagram is to a CRT (cathode ray tube) diagram. ie. an old-timey TV for the kiddos out there.
Can you do a video on Frank Tipler's Omega Point?
We need to investigate more into the following technologies:
-Matter/anti-matter propulsion
-warp drive or the alcubeir drive
Hmm and what about stopping at final destination? It would probably take same time as we needed to accelerate to the top speed right?
Do a turn and burn at the halfway point to start decelerating, this also can generate artificial gravity for the craft as well, which would be helpful for manned missions.
Hi Joe Scott you make very good easy going videos👍😀
Maybe you could also do one on Aneutronic Fusion Space drive systems that are now being researched? Also you did not mention the possibility of nuclear powered Ion/plasma rockets... There is also the future possibility of using Aneutronic Fusion reactors for future missions...
Thank you Joe 😊 I've been waiting for this for a very long time. Awesome explanation, first person I've ever seen to explain this in layman terms. I have a question though if you have the time to answer: i red a book called Foot fall, alien invasion and all that stuff. Humans had to get in to space all that usual stuff. What they did was create a platform of massively reinforced titanium. Propulsion was achieved by nuclear explosion underneath the reinforced platform. They also had bombs that came out of the side to gain thrust once in the air. I cant remeber the exact numbers but i think they managed thrust up to 2% light speed. What are your thoughts on this?
Also on a side note, audible books to read: expeditiinary force books there are 5 of them so far. Some of the best science fiction I've read.
If your into fantasy: Night Angel trilogy and Light bringer series by Brent weeks. As always Joe, love your work, thank you lots and lots and heaps for what you do 😀
My favorite is the Twin Ion Drive (aka TIE fighter)
I think an ion drive passing voyager would be more like the hare surpassing the tortoise after the tortoises giant head start lol
I have followed the ion drive or propulsion engine and something I have kinda wandered about and have not heard a lot about is maintenance on these engines seems to me the engine would not only be very efficient, but would be able to be repaired or even removed and/or replaced mid mission.
Hey where'd you get the vintage typewriter, I love it
Brilliant and I like Joe because he's very trustworthy for one also he's funny and you don't usually get those two in the same spot right there I always knew I was special Joe but you're the first one to confirm it
I hate to say it but AI could help with unknown drives given the right information without paradoxes possibly or am I just stupid
hey how do they make the electrons at the back of the engine Joe
Gravitational assist + ion drive + solar sail would more than be enough to get to alpha centuri. We need to do this!!
Audible is the answer to chewing through your reading list backlog! I listen at 2x speed...working up to 2.5 ...my goal is 3x . My brain adapts remarkably fast. It’s weird when I get out of my car and encounter a “normal speed “ human, it must be how a hummingbird hears us!
Ken Ham is supporting you?? Intriguing 😁
Hey Joe, you should check out Magnetic Reconnection and the MMS mission - it's what drives our aurora borealis. When two opposing field lines merge, it causes a "Magnetic Explosion" Plasma (CME) from the sun reaches earths opposing field lines, magnetic energy is converted to Kinetic Energy in the plasma (Large flow rate, which is what we need in ion drives). This isn't currently used in ion drives - but it should be. One could essentially create a very very fast flow of ions in a vortex, toroid, stream - whatever you want - then further use magnetic fields to manipulate that. Magnetic reconnection between the Sun and the Earth can be thought of as a simple, almost 1D interaction. But if you use two opposing toroids, or multiple solenoids etc, you can create complex reconnection - even infinite loops of reconnection (where the moneys at). There are papers out there which have proposed magnetic reconnection thrusters - that's the next step.
If you consider that magnetic reconnection causes an energy transfer to accelerate ions or charged particles - maybe there is a way to do it for an entire space ship and move between stars. Very local magnetic field of the ship weakly coupling to that of nearby stars or planets perhaps? I imagine the frequency would drive it, when the fields of the sun and ship merge, the ship gets pulled towards the star (XGHz/MHz/KHz) - no propellant, just magnetic coupling, so potentially insane speeds.
Secondary to magnetic reconnection being usefull for ion propulsion - it's going to revolutionize wireless transfer of power. Instead of putting the reconnection point in outside of the ionosphere, you set the point between two charged spheres to be on the collecting sphere. If you use low power, high voltage electrostatic charges to create the mangetic fields which reconnect, then you can continuously *pinch* the electrons on the collecting sphere from the power supply (charged sphere where the power is) to create current - no reason why this shouldn't work over the same distance as radio.
AKA Tesla Longitudinal Electric Waves.
I'm really excited for MIT's ion engine plane.
If you click on the purple icon you can see videos of an ion drive that can lift its power supply form the ground!... Traditionally the ion drive was a looong way from being able to lift its power supply, yet this one can do it. I think it has lots of potential. Please take a look.
You should do a video about sun sail micro-probes being sent to nearby stars.
What about magneto plasma dynamic drives? I've heard about a Lithium Lorentz Force Accelerator, which is supposed to give you a little of both worlds. The top speed and efficiency of a ion drive, but with enough acceleration to be able to pull of some delta v maneuvers.
You need to watch the Expanse!
plasma drives and photon (rf/visible/x/y) drives, m-drive might work if thought to work like a rf laser, maser
hey just wanted to suggest something, might be a good idea to look up hemochromatosis, some members of my family have that and one of its symptoms is dark circles around the eyes. ive noticed that in your videos the circles around your eyes are darker than in the average person. not looking to insult you with that just want to make sure your healthy because the world needs poeple like you.
Dude you make the best videos when you’re stoned (i know its allergies)😉. Another good one!! 👍🏼
Ion drives seem close to the injector of particle accelerators, would there be a chance of attaching the rest of a Linear accelerator as an afterburner or would the weight would be too much for the added thrust?
What about the magnetoplasmic drive or plasma proulsion thrusters
I advise The Bobiverse trilogy which is on Audible. AI constructs of Admiral Akbar, commander Riker and a butler in the form of John Cleese. Absolutely brilliant set of audio books.
Speed yes, but endurance mostly. Good for station keeping.
Great Video! Just wondering how would an Ion drive ship slow down when approaching another system without taking as much time slowing as it did to speed up?
@@obsetube1725 Definitely nothing good
This is only the beginning of ion technology and electronic propulsion.🛫🚀🛩
Joe have you ever done a video about thermal nuclear Rockets
You want an audiobook recommendation, try Homo Deus or Sapiens by Yuval Harari! You'd love it!
Good call!
I can’t find that audible book, “Physics of the Future” :( (probably because I’m in Australia)
Really? Weird. I made sure and looked it up before I mentioned it.
You have to search upside down
maybe you meant "Physics of the Impossible"
Me neither, I'm in Finland. But I downloaded "The future of humanity" and it's great.
Ditto for the UK
Thanks for another very interesting video Joe. I've been reading about the NASA X3 drive and it looks really promising. Perhaps in 150 years time we will be zooming around our own solar system mining asteroids - looking after the life we found on Europa and gasping at the photographs of exoplanets orbiting the star group of Alpha Centurai (sent back by laser powered nano probes accelerated to 20% of the speed of light). Mars is only 2 weeks away by our fastest ships and there's a mission to visit Pluto and perhaps do some skiing there. Let's hope we get through what appears is going to be a very turbulent 21st century.
Hey there Joe Scott if they were to scale up the mit ion plane to use a small nuke power plant would that not work to fly a moderate size machine?
That pun at the beginning made me like the video right away.
Pretty good Dad joke considering I'm not a dad.
Fix that Joe... The world needs all the Joes-like-you it can get! If you won't do it, who will? :-)
1K ion drive and the Vasimr drive I believe will quickly (a decade or so) become ubiquitous for interplanetary travel by all unmanned probes and used as the ‘powered’ coast drive for manned spaceships. Chemical rockets will give the initial course ‘kick or injection’ but then the months long cruise phase will use the electromagnetic drives for acceleration to the half way point, turn about, then decelerate the second half. The final orbital insertion completed by atmospheric skimming or chemical rockets. The secondary drives also give some redundancy to potential chemical engine failure and vice versa.
To return, in situ fuel production for rockets but the other coast drives will have the complete fuel load for return trajectories from the start. This also provides a margin for mechanical error and potential flight recovery in the long term if the ‘mag drives’ can recover an overshoot for example.
Love the shows return to hard space science & tech, jus luv it!
Nice thumbnail too Joe.
I’m confident Tesla and Spacex will have their own engine development by the time Mars shots become a regular thing - just imagine dude- A scheduled service to Mars - F*** Yerr!
A video on the X3 drive?
My favorite is the Twin Ion Engine...
I have my ION Pamela Anderson ... does that count as a favorite?
