Cannons to the Planets

[apex02001]

Why not use an electromagnetic mass driver gun?

[iLOVENATURE2011]

im not that technical when it comes to combustion based technology, but i find this video informative though...

[tabalitigi]

it's sad to see such smart people conceptualizing such dumb concepts...

we need to think "sailboats", not "guns" for intergalactic travel or any sort of new age interstellar travel...

This whole "projectile" fixation is fucking archaic...

[whohasgottenit]

@tabalitigi This is meant to be a launching system, not an interplanetary traveling system. The current launchers are VERY havy compared to the payload they're shipping. Every kilogram you take up to space needs a lot of kilograms of fuel and launcher to take to space. If you could use this "gun"-system for small and light satalites, or for example the solar sail you're referring to, you would eliminate a large fraction of mission cost.

[tabalitigi]

@whohasgottenit

I'm saying we need to start thinking beyond projectiles and combustion...

[whohasgottenit]

@tabalitigi I understood what you said, but why? If, for small projectiles, this way of launching things is way more efficient, why not use it? The fact that it's an old concept doesn't mean anything.. We have been using launchers(rockets) for 50 years or so now so that's not really new either. It's been a trend in the last couple of years to make smaller satellites and such, and those could easily be shot into space with a projectile rather than being launched with a huge rocket.

[tabalitigi]

@whohasgottenit :because we are in an age of waste...We are stuck in the mindset from the industrial age, and combustion based technology is NO WAY to travel/send supplies efficiently LONG TERM...We are thinking in the "NOW", and that now is VERY archaic...The "modern" technology just needs to die off, and let the quantum age move in. I am not advocating "stopping" space travel. These "projectile based" concepts are just archaic to be nice. We are too eager to go space without a REAL plan...

[twdarkflame]

@tabalitigi We do live in a age of waste. But this idea wastes far,far less because you dont need to speed a load of fuel merely to carry fuel! This design could make huge savings and increase access to space within a decade. I'm all for research into space-elivators and other more efficiant designs. But this is "now" tech, a space elivator at best is 50 years away.

Nice closed captioning! "Foadable Tags" @ 17:40

It's 'photovoltaics' if anyone doesn't know.

[WarblesOnALot]

@GoogleTech Talks G'day, nice clip, if a tad fanciful... If ya enjoy looking at hardware that's real, try searching 'solar thermal ramjet', & see where NASA managed to come 2nd to an Australian Hillbilly ! 'Twas but a 5th-Order Design-Priority, but one couldn't resist... Search 'sunfoil' for interlocking clips covering all aspects. Open Source, view the Data on the "Science" clip; the "Short-Talk" includes the CSIRO Evaluation. Enjoy... Ciao !

Gerald Bull, the father of the project, was assassinated. See qvCYZ2p8yTA

[demmylowther]

Is this an exclusive American project ,or are there other countries doing this as well,and if so,are they ahead of the USA?This technology is absolutely fascinating.Does anyone know if there has been any big strides taken place in space elevator technology?I do understand that nano(nanotubes) technology is the most important accomplishment if this has any possibility of ever working some day.Would this be an accurate statement ?I know there are many other hurdles/barriers to jump as well.Thanx

[demmylowther]

After accidently coming across this utube site(previously I was just checking out all types of sites which had NOTHING to do with science,period),I'm coming to the realization that I'm not a dumb person.I never finished high school,but eventually got my GED(Good Enough Diploma),but anyway,I had this idea about 20 years ago of building a gigantic gun that would shoot projectiles into space.

My concerns were the same as this man speaking,and that was the effects of G forces on electronics.

[OtherworldJudge89]

I cannot believe I just watched all of that.

[velveetaslingshot]

Wow. With this technology, it suddenly becomes feasible for private industry to build a space "hotel" for space tourism.

Use a cern type of set up and launch a new Man made satelite to any planet or any moon. Voila

[bellrockyin]

Thankz for posting!... the little satellite is amazing!!!

[MoxieChan]

11 kilometres per second ?!? for how long?

and why the fuck is there a video with jennifer lopez in an ugly body suit on the right?

[circusboy90210]

@MoxieChan do the math .. you only need a slide rule paper & handheld portable graphic inerface device. it's not that difficult it's been done since ernst mach & the 13th century.

[spadehatesscrewtube]

@MoxieChan 've noticed lots of that happening too. i was searching for knox's the matrix reloaded, and a breast feeding video came up in the right hand side ..

[circusboy90210]

magnetic propulsion is a far better bet, and probably alot safer.

[cptbritain]

@circusboy90210 At 25:15 minutes he explains why it's not a "far better bet"

[circusboy90210]

@circusboy90210 opiinion & conjeecture probably a comination of the both is better.

Help with the CC: It's "Asymptote" and "Photovoltaics"

[lizzizzleVIP]

That was crazy awsome!

[Mosfet510]

T hey called it the "Doomsday gun" the Howard Bull story I think, good movie.

[deltapeco]

search Gerald Bull Space Gun on this site he was the originater of the space cannon almost built one but was assasinated before he could finish it by the messad

[mrdoornbos]

If I was looking for a primer on G force hardening, where would I start?

[AVKtt]

This project can be used as a first step for launching into orbit of the earth materials and structural components are small and not sensitive to very high accelerations.

[justicetrooper]

I think it'd be fruitful if instead of worrying about how we have come across this technology, or any of the historical arguments brought from such, we simply put energy into developing and producing such technology.

Unfortunately the only ones capable of easily developing expensive tech is either the government or rich people.

[IndrasBlade77]

These ideas are all cool, but really the only viable space exploration technology would be an anti-gravity based system, manipulation of the 'Higgs field' or the 'dimensional fabric'.

Intense magnetic fields may be involved though and that could pose problems.

[sirsmokesalotaganja2]

w00t for the nazi's figuring out to spin super fluid mercury to make a electro magnetic field vortex bending space and time :)!! and hahaha i loved the NG where they shot a missile in a small shed and said theirs no way a missile hit the pentagon.. i was like O_o that just proves these people are STUPID

[daveyboi03]

TR-3B

it uses electromagnetized ferro fluid mercury in a supercooled state which rotates 50,000-80,000 RPMs in a small disk like generator... it goes faster than mach 50 and is what most people know as the trinagle UFOs... no those aren't aliens they're ours.

this is great but is not needed anymore...

[Odziz]

To the Space Gun and so we end an age...

[hemojr]

An ocean location also will absorb the shock from the recoil. However a mountain location is usually proposed for canon, catapults and rail guns to shoot things into orbit. It might be cost effective to create a man made lake or reservoir at altitude (in say, the Andes) to avoid the thickest part of the atmosphere. Lakes are not typically deep enough, but with the right engineering, this actually might be a workable modification.

[1HumanKind]

@hemojr

You so funny. Recoil. hahahahaha.

And people believe you too!

[XSAlexio]

@1HumanKind

There is massive recoil! What's the joke?

[spadehatesscrewtube]

@XSAlexio your matriarchal parental units mons pubis could absorb the kinetic energy of almost any recoil.

(sorry, couldn't resist. no really, thats what she told me!)

[XSAlexio]

@spadehatesscrewtube

I know man, but your mother's seemed more fragile. I might have killed her!

[spadehatesscrewtube]

@XSAlexio ah, the games afoot.

[omikron441]

@hemojr Well there's Lake Toba in Indonesia, at the apex of the long dormant Toba volcano, 2805 metres above sea level. Seems to fit all the criteris you've mentioned

[kmingtsai]

I think the method can be used to project sun light reflective material to the orbit to reflect part of the sun light to the earth.

[brinksbury]

I think this is brilliant. Ocean pressures help keep the barrel together. Ocean allows it to change direction easily (its very very long), and the ocean will keep the barrel from getting too hot.

Sounds very plausible. I hope they build one. (Just one as I expect there will be improvements)

[9ff70f96]

A question I would ask is could there be a concern for ocean life in the vicinity if it was to produce a huge bang under water?

Sounds really interesting though and strikes me as promising given the research already conducted to prove the technology.

[Krawnikal]

I usually do not like to cite mythbusters here, but they did do tests where shockwaves from bullets being fired in water would kill a fish, so if this huge hydrogen powered gun shot off, then I would say yes, this would kill marine life in it's direct vicinity.

[sirsmokesalotaganja2]

look up physicists talking about mythbusters they say mythbusters set their experiments up wrong making them have to fail...

[knight2255]

@Krawnikal

Before each shot they will fire a small non harming explosion that will only scare all wildlife away from any deadly shock forces

[eggaweb]

@9ff70f96 I don't know much about this but I would suspect that most of the sound would come from the rip of the barrel (like with normal guns).

[eggaweb]

@9ff70f96 I don't know much about this but I would suspect that most of the sound would come from the rip of the barrel (like with normal guns).

[kenshin0694]

I think instead of elevating the gun they should just dig cleave shaft in the ground and set the gun in it.

[pu3he]

This cannon is nothing short of amazing.

[pete275]

hydrogen? Oh, the humanity!

[roidroid]

@ 52:30 the spinning ring toy he is talking about is called the "Zyclone Ring Blaster". I hope this helps someone else who found it difficult to understand what he said.
