  • Just need a million volt power line at 600 hertz to levitate, then you can't get to it at all.

  • Its so sad I wont see this in my lifetime! I wish I could visit space like this!

  • Why wait for something in a century when we can start building a rotovator tomorrow that is 100 times better? Instead of a month to climb to orbit a rotorvator will get you to orbit in 30 minutes. Three rotorvators can get you from suborbital earth to the moon and back using no energy, it's simply stored in the rotating tether and then released when you come back to earth for no net cost. google momentum exchange tether

  • @iknowfacts Stairway to Heaven

  • You are not going to build a space elevator from the Earth to the Moon. As you point out, the relative motions of the Earth & Moon render this impossible. However, you can build a space elevator up from the Lunar surface, past the L1 Lagrange point, and into cis-lunar space. This is the only space elevator that can be built near term (this decade) using existing technology, and it will become an essential part of the space infrastructure, enabling easy access to and from the Lunar surface.

  • @AmericaFreeTV You could build a set of rotating tethers now (with existing tech) that gets you from the earth to the moon and back for no energy cost.

  • @chrisblaster18

    A coil gun system would be better, less friction and heat

  • @stealthlol266 The problem with rail guns and coil guns is 2 things - 1. the escape velocity of Earth is so fast (about Mach 32 / 11km/s) that the construction methods to build such heat and pressure resistant vehicles has not yet been found.

    Additionally, the railgun has to be straight, and tens of km tall. You'd basically need a railgun which extends to space, which is a bit redundant then and pretty much impossible to build with today's materials.

  • Could you use a rail gun system to shoot your ship in to space?

  • @chrisblaster18

    That's an idiotic idea.

  • Can't wait  !

  • hey Michio Kaku, i see you in CP#5Br

  • I think phineas and ferb did this already.

  • please be in my lifetime.

  • The first space elevator, one for the Moon, is a practical goal and work on it should begin now.

  • @AmericaFreeTV How are you going to build a space elevator to the moon when the moon rotates around the Earth?

  • This is the kinda stuff that makes me wish I could live forever

  • Someone tell me what the music is called, lol.

  • Electric Universe Theory will help make this happen sooner.. Just as soon as as a scientist steps forward to back up the Theory and not be afraid of losing his reputation or some bullshit like that.

  • it will be reality in maybe 35 years or less!

  • the british universities and the americans in general are building nanotubes everyday. we need more factories.

  • I wonder what the elevator music would be

  • @iknowfacts LOL, I hope they play Metallica, and maybe an plasma tv+xbox?

  • @iknowfacts definitely the star wars imperial march.

  • @iknowfacts death metal

  • What's the name of the song that's being played?

  • I want this song!

  • Imagine the waiting list to board it

  • It would be nice to see...but if the record for that carbon nanotube is less than an inch then my guess is that crap's probably a ton more expensive to make enough to break our atmosphere than just using a shuttle.

  • Why not? Because the international space station isn't in a geostationary orbit.

  • Ben Bova wrote a novel in which one of these was built. Unfortunately it was sabotaged due to the fact it would put commercial rocket firms out of business and came crashing down. Of course his was app. 70,000 meters long, so when it crashed it caused quite a mess. A dismal story, but he did a good job of explaining the science behind the concept.

  • few phrases had open my mind so fast as "open up the universe to the average person" ...just awsome

    PS: great music by the way

  • wow! single column, must've gotten this idea from Dragon balls' Kami Sama Temple. lol

  • We probably would be constructing it now, but no. Apparently, we would rather spend our money ($300,000,000/day approximately) on killing brown people in the the Middle East instead.

  • amazing (':

  • The backround music makes me think of halo right b4 a huge fight

  • Uh, the cable would have to be 42,164 km long to obtain a geosynchronous orbit. If tethered to the ISS the cable would stretch along the orbit of the space station's path and would either...

    1) uproot the anchor system

    2) break the carbon nanotube cable

    3) haul the space station into a lower orbit, careening it towards the surface of the earth.

  • @DMFermiPhysics Sorry that 42,164 figure is with respect to the center of the earth...35,786 km from sea level...

  • @DMFermiPhysics This is a theoretical concept, meaning that numbers show that it can be done. Carbon nanotubes are tough; they're not going to break easily. Anchoring shouldn't be a problem. It's just a matter of anchoring deep enough. With that, keeping it into orbit shouldn't be a problem.

  • @Nathan173AB The problem is that the ISS is only at an altitude of about 460 km at MAXIMUM and it makes 15.7 orbits PER DAY. How dow you anchor THAT to a single location from which to run an elevator. The answer is you cannot and have to place the tether at a position 35,000+ km away.

  • @DMFermiPhysics Many prominent scientists are backing the space elevator, saying that it's not far around the corner. By saying that it can't work, you're really just saying that you lack the knowledge or tenacity to make it work. That's probably why you're not among those prominent scientists and, instead, are here on YouTube challenging their knowledge, which would be fine if you really were way ahead of them, but I doubt that's the case. :-/

  • @Nathan173AB Sure the space elevator is feasible idea if you develop a tether positioned at a geosynchronous orbit - there's no argument there. If you've actually READ any of Michio Kaku's books he himself suggests this. That's why it was disappointing to hear him suggest a tether could be connected to the ISS and anchored to function as a stable elevator. It can't - that's just the truth of elementary physics involved. The beauty of our world is that physics doesn't favour prominence.

  • @DMFermiPhysics Besides, I thought this thing was in orbit. Why is it all of the sudden ripping the anchor out of the ground?

  • @Nathan173AB A tether for an elevator needs two points of contact, one on the ground and one in orbit.

  • @DMFermiPhysics You don't have to anchor it. Have it rotating so that the tip goes against the direction of the orbit. The tip is almost (about 4 km/s) stationary with respect to the earth. A small rocket can reach it, grapple on and be carried up to orbit. When it comes time to deorbit reverse the process. No heatsheild needed because you're going so much slower. Don't need a "climber" or a power source, just a hook.

  • Yes and no...you don't have to anchor the stage of the elevator that's in space once it has achieved a geostationary orbit 22,000 mi up, but the section from orbit to the Earth most definitely needs to be anchored!

  • @DMFermiPhysics No really, you don't need to anchor it or have some kind of super strong material. Have a longish bit of reasonably conventional rope. (damage tolerant rope). Put it in low earth orbit (not geosync). Make it rotate so that the tip speed is maybe half orbital speed or so. (stronger rope can rotate faster). To go up, (think SpaceShipOne) sub orbital, grapple the rope. Hold on for half a rotation and release. Presto, you're in orbit. Reverse to deorbit.

  • @DMFermiPhysics It's hard to explain in 500 characters. Could you google "hypersonic Airplane Space Tether Orbital Launch System" I think you'll be surprised and intrigued by how simple, light, affordable and doable it is to put up a space elevator. With a *little* funding we could see it up there and putting payloads in orbit for 10 dollars a kg in two or three years.

  • we need to build an artificial ring around thisplanet connected to the surface by space elevators. It can be used as a space port for shuttles and ships while also a residential and commercial hub. That would be sweet.

  • Does anyone know what the music is in the background? So inspiring!!!

  • This technology has to be our future

  • It's awesome until a comet starts coming at you bro.

  • i love this idea im gonna develope it lol..

  • For all you scientific minded people (cause I don't have a clue), would it be possible to have a space station in low earth orbit (or maybe a bit higher), where a section of the space station could be lowered on a tether into the Earth's atmosphere, low enough that a high flying plane or similar could board, and then be pulled up?

  • @matthewakian2 its not possible to keep the space station in earth's atmosphere because the gravity is much greater inside the atmosphere...but after first 100 miles the gravity becomes low so any satellite or space station can float.

  • @ayon16 Thanks. 

  • @matthewakian2 Yes. If the tether rotates then the high flying plane doesn't need to go as fast (sub orbital).  Reverse the process to come back and you don't need a heat shield.

  • This is wonderful!!!!

  • This is the only way that we will colonize other planets. I can't see it happening if we build the damn ships on Earth, we need to build them in orbit.

  • Lol youtube comments.

  • The music! What is it? Why does no one know the answer?!

  • @WOLF333999 if you ever find what is it let me know bro

  • Absolutely amazing

  • A barge???

  • FYI we have electric powered space craft who needs this dangerous BS!

  • --- and her excuse was she was an astronaut and she actually went in orbit, she seemed like a 14 girl to me whom couldn't get her facts straight but i guess naysay is used being full of it and in their own world!

  • The first person that tries to make that happen needs to B shot on sight! First you need 2 to balance it out and second it will slow down the rotation of the Earth and is compounded by the time element it's being used! Lastly going into orbit isn't even going into the solar system much less the universe, i had this same conversation with a scrawny black haired pissy chick that thought orbit was the universe ---->

  • Problem with all these Ideas are that we are moving to slowly. The amount of knowledge that needs to be accumulated in human, to make new discoveries are ever increasing. The focus on educational methods to speed up learning process is a necessity to make our civilization to go from a type 0 to type 1. Furthermore the humans must be re-leaved of monotonous works and work tasks. It is very possible to make this happen today, but science community isn't cooperating enough with the industry.

  • To all my fellow science enthusiasts: if you're like me, you're tired of only seeing amazing technologies and possibilities in books and on youtube, and you want to see this actually happen. And I think there's one thing that will determine when and if it happens: the demand from the general public. If you're a tax payer, why not let your government know that this is what you value and what you want to see happen? They can't ignore us if there's enough of us.

  • Does anyone know the name of the song?

  • @MrLucascanuto i wanna know too ;)

  • Commander Shepard was here

  • These things are fun to think & imagine about but I don't think real scientist are looking for this to happen. Might make a good movie though....

  • Comment removed

  • @YManCyberDude Real scientists have been looking into this for over a decade, and making real progress. It might still be a long ways away (100 or more years), but the foundations of this have already started. Just look up the NASA tether challenge for just one example.

  • @denebkaitoz … Real scientist have been looking into allot of things for many years but this will still never happen. It's just one of those things. 50 years ago science thought we'd have cities on the moon too. They've only been able to produce a handful of these nano fibers at incredible cost… Even if they could crank them out cheap it would cost trillions of dollars to make the elevator. Technology & progress rarely ever go in predicted directions… This will be one of those…

  • I hope.

  • It also can be a way for space ships to "Dock" with a planet like mars in a geostationary orbit, and be able to transport people and cargo to the surface.

  • The best thing about this video?? The super awesome music!! :D

    Can somebody pleasssssssseeeeeee tell me where the music towards the end is taken from?

    Thanks...

  • I agree with any person who says an elevator to the moon and mars is impossible. But we could have an elevator on mars and the moon so from elevator on earth it's less to coast upon.

  • The elevator could never go from here to Luna or here to Mars. Both of them have different patterns of orbits, the cable would be destroyed so easily as it would be pulled by the planets. It could be used to save energy if it's big enough to launch ships from space though. That would save a substantial amount of fuel because this elevator could easily be solar powered.

  • What is the name of the song??

  • the iss is moving 17000mph reletive to the ground. good luck catching that cable and deorbiting the iss.

    you need to go geosync and thats enough cable to wrap around the earth

  • Michio Kaku is Aeolia Shenberg.

  • Good to see I'm not the only one fascinated by the idea of a space elevator, I dream of being able to aid in it's construction.

  • Comment removed

  • @JassiusJay Yes, totally, go do it then.

  • Comment removed

  • If it lost power, could you take the stairs?

  • If you were on that space elevator, and some little Brat got on and pressed all the buttons so you'd stop at EVERY floor all the way up to space....it'd be REALLY annoying.

  • @wuweiwarrior

    Not really since floor 1 is the earth's surface and floor 2 is like 60,000 miles out.

  • They better not have typical elevator music in that thing, or it'd be REALLY unbearable ride. :-P

  • omg they are stealing my ideas! :)

  • I find it easier to make a portal!

  • if only governments could understand that investing in space development is something that will not only bring back great profit (asteroids have more minerals than humans have mined on earth) but also will ensure our long term survival by spreading out into space, as a species it is our duty to preserve life even after the death of our planet, so why are we detained by money?

  • At age 76, I'm going to space on one of these. IF man has not destroyed itself by then.

  • I highly doubt this will be possible in our lifetime T_T

  • this could certainly revolutionize space travel but I think those prohibitive costs will be long ago dealt with before the space elevator is seriously considered.

    Within the next 15-20 years, private space companies (of particular interest are SpaceX and Orbital Sciences) will dramatically reduce the costs of space travel (and ultimately exploration) through competition, vertical integration, engineering innovation and a booming new space industry.

  • Hopefully during our lifetime :)

  • Impressive. Can't wait!

  • Someday!

  • Excellent video. Anyone know the name of the song?

  • Shit, that's a good video, and good music too! Damn government is all bitchy about money, and this would save money I think and put us morely into the future.

  • Alas, classical mechanics does not give mankind interstellar transport. Need to experiment with magnitoelectrodinamics or quantum states. For example, the cosmic engine, which controls the probability of finding a spacecraft in a particular point of the universe.

  • Look to the stars for hope burns bright.

  • I'll cry tears of joy if I ever see the day in which this project becomes a reality.

  • @dragster178 me too! ..but it'll probably happen in 300000000000000000000 AD!

  • @dragster178

    I think lots of people will.

    If that merely becoming reality makes you weep, wait till you get on the thing! If this ever gets built it will be one of the greatest devices ever constructed, if not the greatest. What device could be more spectacular than a device that allows humans to get off of the planet safely and routinely? We could reach other planets so much more easily. Space colonization's first step and only real obstacle is affordable access to space.

  • You and people alike are the reason why we aren't seeing any progress. You can't sit around and wait for a miracle you need to be part of it. Get involved and do something about it. What will be your legacy to the world? Albert Einstein was an average guy with a passion. He wanted to change the world he wanted to get involved. He knew that if he didn't there would be no beginning and nobody else would. We live in an age of dreamers.

  • @dragster178 i bet u 100 bucks that we'll see it near 2045 ! ^^

  • I cried a bit from joy.

  • Brilliant Video, nice choice of music. I actually stopped listening halfway through and imagined a story of an old man who got to see this actually happen before he died, and sold everything he owned just to be one of the first to ride it.

  • Anything and everything Dr. Kaku ... this guy is a great advocate for Science.

  • Watch the documentary MOON RISING... NASA has already photographed existing space elevators, different space crafts and large base complex on the moon. We are already there and beyond. They are just tuning your brain into whats real so your brain wont overloaded and fried when you see the real thing.

    Peace!

  • @mrfeldt

    Lol. if moon bases are true, don't you think they've been seen by people who gaze through their telescopes as a hobby?

  • @mrfeldt wow, watch the documentary DID WE LAND ON THE MOON.... will that convince you we never landed on the moon? are you 12 years old to believe these idiots who say they are scientists? moon rising is just another shit conspiracy documentary created by idiots who don't know what science is, please die.

  • i would like to see you get that cable up there
