Skyscraper that hangs from asteroid -BUSTED!

my new skyscraper gonzo could bring people to astronomical new heights [Music] clouds architecture office as unveiled plans for a futuristic skyscraper called the analemma tower the building would hover above the ground because it would be attached to an asteroid in space look at this thing this really puts the sky in skyscraper a design firm now has come up with this idea for a floating skyscraper there would be ultra-high strength cable to hang that building from an asteroid forcibly put into orbit around the planet that of course means that your address could be anywhere on earth actually physically hanging from a cable New York architecture firm has drawn up plans for the tallest building you might have been expecting me to say the tallest building on earth but that's the catch clouds architecture office says this tower would be suspended from a large asteroid that's placed into orbit above the earth it's going to be lightweight solar powered and used water from the clouds the skyscraper would always be moving right floating skyscrapers tied to an asteroid in orbit who would float majestically over New York that you would only leave by parachute that was colored by so many news organizations in beggars belief Newsweek Popular Mechanics Forbes the Independent Business Insider and so on and God did I get so many calls to debunk this crap so let's start with a more obvious practical element to this where do I flush the toilet where is the water go what the hell are you going to get your water from all your electricity oh but they're going to get the water from the atmosphere right here right they're going to get all the water to water all the people in that entire skyscraper Josh Matt will be the dips into the atmosphere respective time about 30,000 people worked in the Twin Towers of the World Trade Center and you didn't what all of those people just by putting a water bucket on top of the skyscraper and that was merely a a hundred or so stories high these things is thousands of stories high and power is that the technology that they've kind of started to brainstorm with this in order for this tower to get power they would actually put solar panels in space make sense they're very close to the fans where it yeah they're all they're going to do it by solar power that's a neat trick until you realize that the International Space Station only has half a dozen people on it and leaves this mini solar panels where are their solar panels I mean how once this thing gets into space and you've got a bear in mind that there's only like 100 kilometers of this is going to be in the atmosphere the remaining 30,000 kilometers of this is going to be in space and it's going to have all of the problems of a spaceship and you know what the biggest window in spaces it's on the International Space Station it's 80 centimeters almost a meter couple of feet that's other side and it cost an absolute fortune the cupola is a pressurized module with six trapezoid side windows and a circular glass roof giving astronauts unique panoramic views my name is Scott Kelly and this is the cupola of the International Space Station the cupola is a small module that provides us a vantage point to see outside of the space station the cupola structure was made out of a single forging in aluminum this is quite an achievement this was a premiere in Europe this is something Europe should be very proud of take the camera here and show you the different windows we have in the cupola this is a facing aft you can see the rear portion of the back of the space station the Russian segment no three in the cupola of the culmination of years of development and construction by either and its contractors and of course any failure in any of this structure basically kills everyone in the skyscraper who's not in an airtight compartment yes it's outrageously dumb on even the most superficial level but it's also kind of dumb on almost every other level what's that they're going to be tethered to an asteroid in geostationary orbit well that's a neat trick I mean let's just take a look at the air the big numbers if you're in the asteroid belt and just so we're clear the asteroid belt is the region between the orbit of Mars and Jupiter so let's just take the largest objects in the asteroid belt light carries to escape from the Sun from the orbit of carries you need about 25 kilometers per second if you're on the earth you need about 42 kilometers per second to escape from the Sun so it's being a state function at all if you want to get from the earth to the asteroid belt you need a change of velocity a Delta V of about 17 kilometers per second bear in mind here of course the speed of sound the speed of a bullet if you have point three kilometers per second or conversely if you want to get from the asteroid belt to earth you also needed Delta V of 17 kilometers per second enter to put the end of perspective escape velocity merely from the earth not including the Sun is about ten kilometers per second and we need giant rockets to get tiny payloads into space so yeah changing orbit around the Sun takes crazy amount of energy so in this case we're looking at Delta V so the energy is half MV squared so ballpark numbers to move just one kilogram it's about the size of a bag of sugar or a one liter pop bottle or something to shift nearly one kilogram of asteroid to earth orbit will take about a hundred and fifty mega joules now ballpark numbers that's the scene energy as 50 kilograms of TNT and that's just leave a 1 kilogram rock from the asteroid belt to the earth and that's assuming a perfect conversion of energy to thrust in reality you'd be lucky to get half of that honestly with equations like this a factor of 2 really makes no difference whatsoever so let's take a small asteroid type 1 kilometer in diameter so if we were to zoom in the Central Park in New York City the entire asteroid would quite happily fit inside Central Park so we're not going to worry too much about the actual exact shape of the asteroid we're just going to approximate it to a sphere with a radius of about half a kilometer so the volume of that sphere is 4/3 PI R cubed about half a billion cubic meters and a cubic meter of rock weighs about about 3 tons so one kilometer diameter asteroid is going to have a mass of about one and a half billion tons or one and a half trillion kilograms each one of those kilograms requires a hundred and fifty mega joules to ship that asteroid from the asteroid belt to the Earth's orbit requiring something like two and a heck of a lot of zeros joules of energy so let's just use the entire energy consumption of mankind as a yardstick here now by lucky chance - and a heck of a lot of zeroes at twenty in this case is also how much energy mankind uses in an entire year the entire planet energy consumption is about 2 to the power of 20 joules so mankind would devote the entire energy a 1 year it could just about get a 1 kilometer asteroid into the Earth's orbit so roughly what would be the cost of that well we know that we spend about 1/10 of our wealth generating power and we know the GDP of the planet is about 100 trillion dollars something like that so that means the just the cost of the energy would be about 10 trillion dollars a little bit more expensive than one of the world's most expensive skyscrapers like say for instance the Freedom Tower which cost about 4 billion dollars but don't worry these people have thought this through they've got a great way to save money and this bill just beggars belief is they say that they're going to save money by doing the construct in the Middle East because the construction costs will be cheaper 10k so the company has even come to define where the construction of the magistrata would be made and that would be Dubai seriously yes I like big things with their titles of get smarter faster every day saying things like this the advantage of making such a building according to the architects is that since it is built in the air it can be constructed and transported anywhere in fact the firm is proposing to build it all over Dubai whether it can be built at 1/5 of what it would take in New York City newsflash guys you couldn't build this in Dubai if you want it in fact the only sensible place you might be able to build this is at the equator and Dubai is not on the equator so you literally couldn't build it from Dubai you would have to build it in space after they've spent something like 10 trillion dollars to get an asteroid and that's ping trillion dollars just for the asteroid that's not including any of the construction costs or the costs for the cable and the other thing is many of these people cite NASA's asteroid return mission as NASA is planning an asteroid retrieval mission in 2021 that could determine whether such a feat is feasible let's take a look at the get faster smarter big think articles they point to some reason asteroid related developments to bolster the feasibility of their plan manipulating asteroids is no longer relegated to science fiction in 2015 the European Space Agency sparked a new round of investment in asteroid mining concerns by proving with its Rosetta mission that it's possible to rendezvous and land on a spinning comet yeah that in quite getting so well nASA has settled an asteroid retrieval mission in 2020 which aims to prove the feasibility of capturing and relocating an asteroid not so much the hell looking a bring back a kilo also of asteroid what a trillion kilograms then they tied up with Wally and Leeman tower is certainly speculative at this point with some of the proposed technologies not yet available it's still an exciting idea straight out of a hopefully near future and because they are obviously impressed by this sort of thing here's another great picture of the tower over New York City my ticket but whatever I give you the asteroid for free I give you the impossible materials to make it from for free cool so you want to hang this building from an asteroid and then dip it into the atmosphere from some asteroid in geostationary orbit so just stationary orbit is the one where you go around the earth once put 24 hours so if you're on the equator in a geostationary orbit that means you're over the exact same place on earth for the whole time and here the radius of the geostationary orbit to the earth size is about right now if that's where they were going to park their asteroid they would save themselves a lot of problems but now they wanted to go around the earth once per day in a geostationary orbit at an elevated angle just so it can flicked majestically over New York City but this means that it will more or less track a line of longitude so here's our geostationary satellite and now what I'm going to do is I'm going to put a second satellite also in the geostationary orbit and increase the elevation of that orbit now what's amazing is this means that your skyscraper or fly over New York City once per day now there is a slight drawback to this plan and Lester the skyscraper has to get up to about 40 degrees of latitude that's four thousand kilometers from the equator cleaning that has to go 4000 kilometers below the equator for the round-trip so that means it's going to do about 8,000 kilometers in 12 hours even if you just take the average speed that the building's moving at 8,000 kilometers in 12 hours you're looking at 600 kilometres per hour about 400 miles per hour average which wouldn't be such a chore until you realize the movements more in a sine wave which gives you a maximum velocity of this building through the atmosphere at somewhere around the speed of sound yeah I think you might have structural and atmospheric drag problems on this idea but that's nothing that's nothing because you will reach the peak speed but somewhere around the equator and guess what the Andes are at about the equator meaning that the building that sort of majestically over New York which has even more majestically into the Andes at about the speed of sound yeah that's kind of brown trousers time especially in a building with no toilets look this whole thing is basically a variant on the space elevator which would be tethered to a single spot on the equator I mean rather than actually start putting a building on the end of the cable you just catch the cable to the ground and use it as a space elevator there is just a tiny problem that the materials don't exist that could possibly do the job yet because cables get longer they get heavier and eventually they just break under the wrong way and we would kind of hit that limit already just with elevators in regular buildings in the world's highest rising elevator there are six and a half miles of cables weighing almost 30 tons because of this weight this elevator is approaching the practical limit of how far elevators can go so theoretical maximum for things like titanium cables is like 30 kilometers and maybe with carbon nanotubes you can do better but the slight disadvantage that we can only make them a few centimeters long and not in any significant quantity but if you could make cables out of them it may be possible to make a cable that would do this but it's right on the limit of what's possible that is if these materials are as strong if they are predicted to be and we can make them which is probably something that is never going to happen it's not just you need a material that's this strong you need that material to be made in one perfect fiber 35,000 kilometers long and any defect anywhere may cause the cable to break or any damage or we're on that cable may cause it to break because even with the theoretical projections of materials that don't even exist yet it's only just possible to hang just the cable I had that's just for the cable holding its own weight never mind putting a giant-ass skyscraper on the bottom of the cable and having it dragged through the atmosphere at about the speed of sound but there were literally hundreds of articles written on this all taken in by their same absolutely bogus computer-generated pictures some even pathetic generated pictures like these and these junk was reported everywhere and he were the people putting spins on it like yeah but building this impossible skyscrapers got some great advantages all right but at least you'd be getting almost 45 minutes of extra daylight the project already has a name the analemma Tower Chuck assumes you're a really stupid project it needs a fancy name I think when I finally get around to making my solid gold hammer simply because it's a really stupid and expensive way of making a really bad hammer I'll give it a fancy name you know Halim has got kind of a ring to it and if you like this media you can support this channel directly through patreon and I'd be very

I can't believe this even needs to be busted.
