@@AOMfreak300 Hardly. ;) I just don't see gasoline-powered cars in our current or alternative future so why describe their usual disasters. Also, spills of fuel dissolving road surfaces, burning down neighbourhoods or poisoning lakes is something we've had for decades already, no (alternative or real) future required.

Yeah, there's genuine Tory moments like the bike jump, and then there's this. Good thing is, most people seem to know it's producer interference, and not Tory being an ass.

[@JMMC1005]

Yeah, deafening someone who wasn't expecting to need ear protection is a massive dick move. The appeal of the show was largely down to the positive dynamic between the hosts - artificial TV 'drama' was not what the audience wanted.

[@comradeurod9805]

​@JMMC1005 i always loved the show for the fact that they seemed genuine. And Adam and Jamie being upfront about not liking each other but putting that aside to work in an amicable and professional way really was one of the things that made it shine

[@InexplicableInside]

I'd honestly be surprised if they didn't receive a stern warning from their Bomb Squad friends after that - if you're not prepared to be responsible with explosives, the risk you present to the professionals jumps dramatically.

16:00 Engineers at the time had this obsession with a vacuum. The first steam engines also worked on that principle even though high pressure has far more power and doesn't require nearly as good seals.

I just love Adam's reactions and he just cracks me up ! great guys, all of them, Grant's passing was very sad > RIP. Just a great science show !

[@Roger-wt8xp]

The thing about lawnmower engines is that the grass cutting blades act as the flywheel. The flywheel keeps the engine rotating between ignitions as well as smoothing out the action of the engine. If you take those blades off, you have less to work with than if you used an internal combustion engine from any other application.

[@UnitSe7en]

The thing about MB is that they're not scientists or engineers, they're entertainers LARPing as scientists - And convincing everyone else that they know what they're doing and their results are valid, too.

[@wackachuisthelordandsavior1954]

​@@UnitSe7en they used to do practical effects. One if the requirment for large scale practicals is engineering experience. That said, you are kinda right. They are entertainers first, actual engineers second. They focus more on flash than they should and it leads to missing simple solutions.

[@ronhastings8439]

also should they use a 2 Strock engine, another way of doing it would be to use shot gun shells with a lower charge, would take hundreds of them to run an engine, but would be good delivery system. i do think it is possible with some decent engineering

[@HyaghoMiranda]

Air Cylinder Rocket and the Blackpowder Motor are two Classic, nice Episode.

[@karenglenn6707]

My favourites are the episodes with the hot water heater explosions. I can watch those episodes over and over again and still feel happiness every time!

[@hemandy94]

I have been waiting for this episode... I can't wait for the 22,000 feet drop episode. That is the one I am most excited for.

[@75keg75]

49:00 it’s essential two torpedos. Those things can sail for 2km on one tank. They are bigger but with these tanks you would expect less than torpedo but more than 100feet. But it unregulated be regulated. Too bad the show is not around anymore to revisit these experiments…

[@steelwasp9375]

Torpedoes have a combustion engine with a propeller. They are miniature submarines. Only some modern experimental torpedoes have a rocket propulsion system, and it ain't compressed air. I'd imagine, rigged underwater, these tanks would travel a similar distance to what they got with the boat. There isn't a boat, but the water drag is much higher than air. It just doesn't have much energy. Like an air balloon rocket, upscaled.

[@unfortunately_fortunate2000]

that second black powder engine could maybe kind of work if they had used something other than a 50ib draw bow over the piston so that they had some rudimentary form of timing, with enough resistance it could in theory work, it is really easy to see why this never caught on though, if the tensioner is too strong your engine doesn't just not work it detonates & turns into a grenade lol. plus I wouldn't wanna breath the air if every car on the road was producing more smoke than the battle of gettysberg...

[@suliemanalfuhaid1447]

They should have added a diverging nozzle to the air cylinders in the first configuration, would have given way more thrust

[@keithdowsett1352]

Well, I know someone who has seen an escaped cylinder. Me. Only a small carbon dioxide tank from a pub cellar, but it made it through the door and into the garden, where nobody went near until it was empty.

[@jocax188723]

I think if you'd have gotten the boat on plane before rocketing off, it might have worked better. As we know, water surface friction at low speed is a pain, and speed gets easier once you get past that.

It's nonsense that black powder has higher energy density than gasoline. Most people think explosives have higher energy density which is rarely true. It just combusts a lot quicker.

[@tsm688]

your figures are off. Include the weight of oxygen in the density and the apparent advantage of oxidizerless fuels goes way down.

[@JMMC1005]

​@@tsm688 That doesn't make them wrong, though. Oxidizer is 'dead mass' when it comes to energy density, but it's part of black powder's composition. The fact that gasoline is stealing its oxidizer from the air is irrelevant unless you're trying to build an engine that runs in space.

[@teresashinkansen9402]

Probably they mixed up power density with energy density.

[@gabrielv.4358]

So if you mix gunpowder with fuel the extra air it has on the gunpowder WILL incraese engine power

[@tsm688]

@@JMMC1005 it is absolutely not "dead mass". Neither gunpowder nor gasoline will do fuck-all without their oxygen. But the oxygen is counted as part of the weight for gunpowder, and *not* for gasoline. This is an artificial inflation of the numbers in favour of gasoline.

A few years ago, Richard Hammond did a documentary, "Gunpowder plot, exploding the legend", to see if the explosion would have worked. it was really good, worth a watch.

After a bridge construction nearby , they had to bring in divers to retrieve oxygen cylinders from mid river . Apparently someone had the bright idea of taking one ,siiting it in the greased channel of an I beam pointing into the river . Then striking the end off with a sledgehammer , for a diy torpedo. It must have been successful because there were an awful lot of cylinders pulled up by those divers.

[@darrenjones3681]

I think they misunderstood the gun powder engine myth more like early larger engines for aircraft and so,e tanks used a shotgun cartridge to start up

[@Huvada]

Grant: “don’t say anything” as he’s wearing an embarrassing suit. Editors: puts it in the intro so it’s part of every episode.

[@yspegel]

To put the air outlet under water; good idea. To put the air output level with the boat; bad idea. To get some distance/speed you want the boat to stay level with the water instead of the front to come up, the rear will become a big break. Put the air outlet pointing slightly down or use an extra rudder to keep the boat level.

[@TooHuman]

29:07 holy shit that joke was dark 😅

[@deezelfairy]

With high pressure cylinders like oxygen tanks the stories of them flying through two walls and being found several hundred yards away are usually when they've been involved in a fire. Imagine a 3000psi oxygen cylinder thats been slowly brewing in workshop fire thats now overpressured to maybe 5-6K psi when something falls on on it inside the burning building - really conceivable they could get some serious air time. The incident i remember as kid was a fire in a mechanics workshop - an oxygen bottle flew through the cinderblock wall into the joinery shop next door (leading to burning the joinery shop out to), out the wall of the joinery shop, over a small river into the bottom of someones garden. Total distance maybe 150-200 yards?

[@DarkGodSeti]

14:04 Haha good timing on my parts. 😏 (Building number)

[@bazra19]

Regarding the boat they should extend a rudder as far behind the Stearn as possible, say 6 to 8 feet. so that if one cylinder only fires, the boat will not go around in cycles.

[@smatt566]

I thought i had seen mithbusters, since im watching them on here i realice i only saw like 20% im watching while i build a bussines and im really enjoying them.

[@Shekssi]

George Cayley engine makes more sense, instead of putting one charge at a time you should mount a 4 cycle charger, you reload on top with a gear wheel it makes a 90 degree snap, another snap makes another 90 degrees where to unload the gunpowder, a sort of 4-stroke charge, charge, wait, unload, wait

I think it's the one with the myth of the executive that broke a window in a high rise office building.

[@simplyhard]

Haha! 07:09 They showcase those fragile, brittle, hollow concrete "bricks". I've even seen the modern rogue, Brian Burshwood break those cinder blocks over his head as a part of a magic act. Apparently they are not sturdy at all. Anyways, then the narrator says something like "let's see if the power of this 2600 psi air cylinder-thing can shatter a solid brick wall"... "Solid" "brick" wall.. Built from fragile, brittle, and more importantly: hollow... "bricks".... "Solid" brick wall... Hollow "bricks".. "Solid" brick wall... Hollow "bricks"... You can probably toss a hammer through that "solid" "brick" wall. I wouldn't be surprised if a glued duplo-lego wall of that size would be sturdier. The definition of solid is better used in describing the 40 pound solid steal bar. That's what solid means. Not fragile, brittle, and hollow cinder blocks.

Not that I expect an actual, solid brick wall to withstand that impact either, but that myth is still untested 😂

"a grain which is 1 /500th of a (*Troy) ounce..." which should NOT to be confused with the ""standard"" Ounce in which case a grain only is approximately 1/437th of an "ounce".

Black powder (and any other explosive) has less energy denisty (1-5 MJ/kg) than gasoline or other fuels (30-40 MJ/kg)

[@vksasdgaming9472]

Interestingly using fuel that carries it's own oxidizer (like gunpowder) could make piston engine work in vacuum. Of course how it would work and what kind of fuel it would use is completely different story.

The Gunpowder inside the engine MIGHT work if you use it mixed with Gasoline, OR Gaseous Fuel (GLP) or something. I WANT A RERUN!!

[@BabyMakR]

TBF they use these to steer Falcon9 rockets, so they aren't useless.

[@LocPH.]

Black powder is not more energy-dense than gasoline. Much less in fact, around 7 times lower. Energy is not the same as power. If your engine runs with air (which it did in all your variants) it's better to use only the carbon in black powder as fuel, you don't need the oxidizer and catalyst. Diesel engines running on carbon powder have been built and run successfully, but suffered from poor emissions and poor reliability. I guess you could convert these engines to run on black powder but there's not much point in doing that.

[@Sethioz]

this gunpowder engine made me laugh, is this best they can come up with? why not make something similar to a gun + pistons? similar concept to that big wheel, but use mechanics like a minigun and instead of bullets, you just make a small reloader where powder is scooped into the new "bullet". it's hard to explain, but it's basically mixing minigun and wheel into one. instead of shooting bullets, it would shoot pistons, shoot as in push them. it might need a kick start, don't forget old cars used a crank and nowday cars would also need a crank if they didn't have electric starter motor. they messed up big time with big wheel, i think if they made it properly and gave it a kick start, it would have actually worked.

Isn't an automatic rifle a black powder engine with a high velocity exhaust pipe?

[@comradeurod9805]

Ehhhhhhhh Black Powder doesn't really lend itself to this kind of engineering because of fowling, dirt from the burnt powder will collect in the barrel, eventually hardening it the barrel(and therefore and obstructing it) or it would just corrode the metal if not cleaned. Only as modern smokeless powder came around did people start experimenting with self loading firearms, partially because of the higher pressure curves of smokeless powder.

[@sazogrim7313]

@@comradeurod9805 so it could theoretically run for a few cycles at least, more than they got with the old designs or the modern engine

[@group555_]

@@sazogrim7313 to my knowledge we're never made an automatic fire arm that works in the sense as they test here. at least to my knowledge. if you describe an automatic fire arm as an engine the fuel wouldn't an explosive powder. it would be the ammunitions. you load in packets of explosive powder and if you want to refuel you need to do so with those packets, you can't just poor in gunpowder. it's an intriguing concept to make a proper engine with that in mind. take the second design, the hard out shell of a cartridge could stop the reset till it's all the way reloaded. if you have a way to eject the cartridge at the end that could be the key to making it function. however I suspect we found the easier way to do it before we got to that point. and as what was said, how long this could run before breaking or exploding is another concern.

If they wanted to test that old drawing of a black powder engine, a single cylinder 4 stroke engine would've been perfect. One would have to remove 2 valves, attach the cable through the spark plug whole, and weld a cap at the bottom of the cylinder. The piston is already designed to do a pretty good gas seal. To remove mass, material could be milled out from the bottom section of the piston (anything at and/or bellow the wrist pin boss).
