If the barrel was longer it would have been much faster, it was still spitting out steam for ages after the projectile left the barrel.

[@alexhellier2008]

Would've got so much more power using a monotube boiler rather than crudely hooking up propane torches to the barrel. They would've been able to achieve much higher pressures than 400psi. At around 750, steam expands at 2500 times the volume of water

[@randylahey2242]

750 psi is for little girls, real men operate at 60k+ psi peak chamber pressure

[@masonrichardson9075]

Average KE for a 7.62x39 round is ~1500ft-lbs. or ~2000J. I don't doubt that 20kJ of energy was released from that steam chamber, but I doubt that the projectile carried that kind of energy.

[@ChannelX24]

Awesome video! Love the look of the cannon. 400psi is very achievable with a pneumatic launcher that would be much smaller and cheaper to produce but this looks way more fun! You are losing allot of steam/pressure after the projectile has been fired. Using a longer barrel and smaller steam chamber will allow quicker filling and much higher projectile velocities!

[@TheEliSko]

Gabe actually, you'd be better still with a very long stroke piston running through the barrel to push the projectile. The piston can then actuate a valve, too, recovering some of the water and saving pressure for the next release. From there you can build up to a Gatling Gun -style arrangement to alternate barrels and pistons, and fire more quickly as you recover between shots.

[@ChannelX24]

Wow Yeah, Very Interesting Concept! I see this Steam Powered Launcher has a whole load of potential. A Gatling gun style system would be incredible? Have you checked out www.spudfiles.com sounds right up your street!

thanks for showing me this gun, I'll use this instead of my ak-47 to fight ISIS. wish me luck...

[@tomoswilliams2827]

Talks about precision but only shoots one ball?

[@dangerszewski9816]

@Vlog Squaaa Smith precision requires repeatability, if multiple projectiles hit at the same spot, that's precision, accuracy is more correct for a single event

[@xcd87]

@PB FAFO yes it does, prescision is how consistently a projectile can hit a spot, shooting one ball cannot determine how precise this gun is.

[@b.hagedash7973]

This cannon could be made a lot more powerful and efficient by injecting a kerosene and oxygen mixture and firing it with an embedded sparkplug, could probably even make it fully automatic with some clever engineering and the hacked ECU from a car.

[@YOUnoobGER]

Yeh 10x the energy of an ak47 when ke=.5mv^2. No wonder it has a ridiculous amount more mass

[@billhill7330]

maybe you should do the relativistic version.

[@sorak185]

Not to mention a massive energy loss simply from not having the contraption sandbagged in place.

[@MrRishik123]

+sorak185 Cody's lab tested whether weighting down cannons does anything. He concluded it doesn't do anything. Since the total momentum still is the same. Just instead of the momentum being transferred to the ball and the cannon, the weighted cannon(which is effectively attached to the earth) causes the momentum to be applied to the entire earth attached to the cannon. Which means the weighted cannon moves less but the ball still receives the same amount of energy.

[@pjmasterzz]

So he made the earth turn faster?

[@MrRishik123]

PeeJay So long as the transfer was made along the earth plane of rotation and the gun was gonna push the earth along that rotation direction. Then yes. But its an immesurable amount. and Even the weather and tides would have made a bigger difference. The sea moving would be like if an iceskater was holding they hands out. If they bring their hands in they spin faster and vice-versa. So the effect of the cannon if weighted down probably would have compressed the dirt behind it when it fired and stuff more than it would have moved the earth. Either way. tis fun physics.

[@andymunns2579]

I don't think this is how this cannon was originally designed. The working end was heated red hot with shot and wadding pre-loaded. Then a shot of water would be injected via a non-return valve. Suspect the pressures would be much higher and almost instantaneous. I have not seen any attempts down this path, but that what the original design looks like to an old steam engineer who knows that the water will expand to steam x1600 times.

[@righteouswrath1774]

"Blow the boys away". 0:27 oh god...

[@R0BL0W]

"powered by a litre of water" - no, it was powered by propane. Water was the medium, not the fuel

[@noodlesthe1st]

Well then you could say powered by oil or powered by prehistoric plants and animals then. Since that's where the propane comes from. The energy is being moved into the water and stored there for a while. It's not chemically stored but physically stored but stored there nonetheless. That makes it the fuel. The medium was air since that's what the ball was being fired through. It's not being fired underwater.

[@bobbypatton4903]

noodles6669 going along with that rhetoric, the energy was provided by the sun.

[@djm7323]

It’s actually powered by human brain.

[@NOBOX7]

quick , get behind the 2mm plexy glass shield

[@nottherealpaulsmith]

I imagine it's quite easy to make something with more power than an AK-47, given that there is no rifle named "AK-47" and there never has been. It also carried more power than an "M2 Garand", an "H&K MP4", and "my social life".

[@stevecummins324]

Rather than use a valve for steam... Fill a metal "bottle" with with water seal with fuse plug of an alloy that melts at temperature beyond that which water boils at. And screw it in to chamber behind projectile. Start heating bottle up and the water inside will heat up, but as pressure also rises it can't turn into steam straight away. Soon as temperature high enough... Fuseable plug starts melting... Pressure blows fusuable plug open. Projectile starts moving. Chamber pressure starts dropping... Very hot water starts boiling... Keeping pressure high.

[@Gruegirl]

shoulda used a watermellon target.

[@piesdescalzos27]

[@MrZum00]

Cool vid, but could use one of those super slow motion cammeras

[@pjmasterzz]

Nice video! One remark though: 30 kg/m² equals 0.04 psi. I'm guessing you meant 30 kg/cm² (as it is the common unit and seems more logic in this casse ;) ). Cheers!

[@fuzzysubjects]

Yeah, the Numbers are off by a couple orders of magnitude and kg/m^2 isn't even a measure of pressure as you might have noticed. BritLab is entertainment and not education after all, I guess.

[@pjmasterzz]

Well, you're right (officially). But where I live (Belgium), we often say 30 kilograms or kg/cm². It's the same as bar :)

Nic dziwnego, ostatecznie od co najmniej 200 lat na dużą skalę wszelkie paliwa (stałe, ciekłe, gazowe i rozszczepialne) zamienia się na energię pary wodnej a z niej wytwarza się energię mechaniczną i elektryczną. To jest potęga.

[@dylandrees6460]

Is there any particular reason you had the muzzle device facing in that downward direction? If it were modeled after the Kalashnikov's then it would be upside down, directing excess blast downward causing the muzzle to rise.

[@WCGwkf]

like another guy said it looks more like the jackhammer muzzlebreak. it was never supposed to look like an AK they were just using 7.62 energy as a comparison which is dumb because this thing is a cannon

[@dylandrees6460]

WCGwkf odd because it does the opposite of what you want your muzzle to do. I don't have any time firing a jackhammer but it seems to be a flawed design and a rather silly thing to draw inspiration from. For the cannon you'd be best flipping it around to work as a slant style break, assuming they didn't want to mill a ported break.

[@WCGwkf]

Dylan Drees I'm pretty sure it's just cosmetic for them and they don't even really need one

[@dylandrees6460]

WCGwkf yeah that's probably it. They would gain more control over the recoil with sand bags more than any break.

I wonder if this woman has the Clausius-Clapeyron equation tattooed somewhere on her.

[@yukisherbet9336]

10x the energy of an AK? No way. Not sure how they measured the energy of that bullet at the muzzle without chronograph, but 10 times an AK means 20.000 Joules wich is more than a .50 BMG round. Also the round was allegedly pushed by 400 psi, a standard 7,62×39 round can develop well over 40.000 psi.

[@JonathanS89]

That was awesome!

[@FriendChicken]

I don't even know how would you launch an ak47 With that speed. A 7.62x39mm I do know.

[@chrissscottt]

30 kg per square meter ain't 400 psi. You made the same basic mistake twice.

[@esejony65]

Gunpowder still more convenient for guns

[@noodlesthe1st]

Which guns still use gunpowder?

[@JaredReabow]

gunpowder refers to any powder used in guns as an explosive medium. Don't be pedantic about the specific names of the powders as you are wrong in this case.

[@noodlesthe1st]

ReabowRotors Firstly where did you get that definition from? because from google it is a specific mixture and in the army I was taught it is a specific mixture. Secondly how can I be wrong if all I did was ask a question?

[@JaredReabow]

It was a question that appears to try and mock the person being asked. As for it being a specific mix, google is just taking a snippet from another website , if you read several other definitions that state " an explosive mixture of substances in the form of a powder, an explosive mixture of substances in the form of a powder, an explosive mixture of substances in the form of a powder" Black powder is commonly referred to as gun powder but it is not defined as such.

[@noodlesthe1st]

ReabowRotors Well he is right. I mean gunpowder is better for guns than steam but I wasn't aware that any guns still use gunpowder. Also I would still like to know where you got that definition from since I just googled the quote and google turned up 0 results. It's just that it goes against what I previously thought and I'd like to know the source to see if it is more reputable than where I got my current information from. Thanks.

[@Biffiee]

It bothers me every single time how her eyes are so far apart.

[@combos16]

"That's what I'm talking about!" Thanks, now I know that I can make a gun using steam. Rather than showing a cool, innovative, and useful thing that would actually impress me on the sciences behind this, instead I learned that water with a bit of heat can be turned into a weapon.

[@Mammophant]

Anyone else have a hard time believing it has 10x the KE of an ak-47?

[@thenoobcannon9830]

not particularly. The 7.62x39 isn't a hugely powerful round.

[@Steamrick]

The AK-47 has pretty low energy as far as rifles go... the 5.45x39mm round you'll encounter most often 'only' has around 1400J of energy. That said, I think what was meant that there's about 10x the energy release (which I'll believe seeing the recoil) rather than that the steel bearing hit with 10x the energy (which would be equivalent to a .50BMG round... which should have gone through all the obstacles there)

[@Mammophant]

yeah I would believe the total energy release thing. I was going to do the math to find out how fast the bearing would have to go but I don't know the diameter. noway it has the energy of a .50 BMG

[@mrcaboosevg6089]

Yes but much like muskets of old it's not a precision thing, whereas modern rifles don't waste any energy this thing was just made in a shed by a man who's probably a builder called Dave
