Yeah, they're still pretty misleading. They measure the bottom-end of their engine and compare it against fully-built and operational engines with half a tank of gas in them. They also measure theoretical performance, instead of what the engine actually produces.
“Physicists tend to dream of theoretical solutions but the people who actually solve the problems are engineers.” 2:37 Reminds me of a quote I love… “In theory, there’s no difference between theory and practice but in practice, there is.” 👍🏼
Stick with the physicists. They will tell youse that the thermodynamics of this engine will inherently produce low efficiency ( high fuel burn for hp produced) because of the very large surface area on the power stroke. That area causes a loss of energy to the casting and that loss is lost power. Which is to say that hemi combustion chambers and 4 valves per cylinder are used by people who know what they are doing. Engines like this are great for uses where efficiency can take a back seat to compact size….say in a torpedo or on a drag strip.

@@Maccaroney And fairly low-powered. And it's absolutely not scalable outside of potentially dimensional scaling of a single rotor engine, but then you run into other obvious issues with physics; the reason rotor number scalability isn't feasible is because the airflow path and temperature play within this engine are absolute dogshit, not to mention properly scaling this would introduce such an asininely convoluted airflow path just to get the engine to breathe, especially if anything past a bi-rotor is hypothetically possible, and planar scaling has physical size limitations not to mention the shafts would have to be geared and that introduces headaches with manufacturing and engine timing. This design really just is not that great, there's probably a reason why Felix himself never settled on it past hypothetical drawings and the basic mechanism of operation. It's a one trick pony, again outside of potentially scaling the dimensions of a singular rotor, it'll have its fifteen seconds of fame again like it did a decade ago (or is it more than a decade now, when did this originally blow up?) and fade into obscurity once again, though this time without the government contracts once those morons figure out they were sold snake oil. This engine just does not have the breathing room to meet the claims they're proposing, I don't think the 2-stroke will fare much better either; the military was sold an underpowered go-kart engine.
@@Maccaroney Wasn't the limitor in the video the transmission gear ratio and not the engine itself? The engine was red lining at 9k RPM, and thus could not accelerate any further. Engine RPM could not be reduced because there was no higher gear to put in. That does not seem like a engine drawback but rather a design drawback of the scooter.
Seeing that your area of interest is predominantly in propulsion methods, I would quite like to see you mount some kind of lightweight air breathing engine to an airframe that would allow it to fly under its own propulsion, maybe something like the old V1s?
a conventional engine can run on Moonshine too. just gotta inject enough fuel and have the right amount of air in a combustible mixture for it to run. as the other comment says if it can be attomized and burn in a exlosive state (ie burn fast enough) then an engine can run on it. i had a HOBBY nitro OS engine running on methylated spirits. (which is literally moonshine with denaturing agent so you can't drink it) it usually a 60% ethanol water mixture
@@thewhitefalcon8539 Uh, leeet's modify that: Some engines can run on anything that burns that has a high enough octane rating to not spontaneously auto ignite during the compression phase, and some engines can run on any hydrocarbon that isn't too thick to go through the injection nozzles. Trying to run a diesel engine on alcohol gets you nowhere, and trying to run a gasoline engine on cooking oil gets you nowhere.
It would be. Especially given there were countless ideas to make them into generators as well. Sadly they never got the interest. Much like the Wankel Rotary, this Liquid Piston company is going to face the same issues as Mazda. Having the technology is one thing, it takes research and endless investment to shift it even if your product can be superior..
@@thetboliproject2890 The biggest single problem the Wankel faced was unburned hydrocarbon emissions from the need to inject oil for apex lubrication and the long combustion chamber which made complete combustion a problem. Durability was not an issue.
It's been great watching how your channel has grown, going from doing sketchy 3d printed engines to here. And as always, this video was a great watch. Looking forward to the next one
Stack 2 or 3 of those and you've got your Go-Kart engine! Just have to mind the timing to get best torque. Glad to see a working prototype. I hope they're successful.
Now that I've seen this engine actually work, my confidence in them has gone up immensely. I feel like their biggest hurdle is gonna be cooling, like the original Rotary Mazda made. But, I'm not an engineer.
That's the problem with the liquid piston design. They can't be stacked like wankle rotary engines can. honestly a lot of what is claimed about this engine seems like a lot of snake oil to me. I was excited when I first saw this engine and I still haven't seen one running that makes the kind of power that they claim it should.
@@bz938Actually, it can. If you design the exhaust manifolds to be similar to those of a Supercharger, you can actually get the exhaust fumes out without affecting the Engine intake. Stop trying to claim something is "Impossiberu", when you have not tried it yourself.
@@Victor-056 it's definitely not impossible but the way the intake and exhaust are currently configured won't allow the engine to be stacked. They can be done with modifications but it may not be as compact as a larger single rotor. The design works and that is something to be proud of. What I don't like is how the designer talks about inventing a new revolutionary kind of cycle. This is clearly still an otto cycle engine.
@bz938 or hooking 2 up to a differential to stack the power like most hybrids use. that way you could theoretically have one half stop running, or run slower in situations where you don't need power from both engines.
It's definitely about the journey! Doesn't matter what the subject is, it's your approach to the problem, the attitude towards finding a solution, and fun you have doing it that bring me back for the next video.

@SimonHowroyd not much has changed. There's a Chinese company making liquid cooled ones for cars now, and a twin rotor one too. Stupid expensive, but well worth it.
I have always been interested in seeing how a Stirling engine would work if you use a manual CVT gearbox as a throttle control, so there's an idea for you to try.
Holy, this is awesome! It's companies like this that need support and adoption to move things forward. This isn't some on paper only idea the fact there is running testable engines and their confidence in them to let you mount it, run vodka through it and just go nuts is some levels of transparency I've never seen! Please do a follow up with theses guys at a later time. As usual learned something new and had a lot of fun watching it. Keep up the great work.
Invester stock options plan. So when they go public you'll see %15 profit even before there IPO. This has promise for drone hybrid car technology. The sealed bearing is the one drawback,but a workaround will materialize.
How about making this an overunity pulsed plasma 2 stroke like Joseph Papp's pulsed plasma 2 stroke engine did. This tapped aetheric ZPE. i just dont understand the obession of burning somethihg to make power.
I absolutley love the sound of it it's like a 3 cylinder, I hope they release a 10hp version just so people can play with rotaries again I would honestly throw one on my go kart
Hey Integza, I had a video idea for you. I saw an article the other day about a 3d printed peristaltic pump, and I thought it would be fun to see you replicate that and see what you can do with the ability to move fluids around!
Here's an idea for a future video - make a centrifuge for filtering heavier particles from a fluid - for example dirt from oil, or resin particles from alcohol (that are most often used in resin 3D printing). The main part is something like a cooking pot, but with additional lip on the top rim. That lip could be something like 2 or 3 cm, and when spinning it would trap fluid on the inner walls in the volume closed by that lip. (the UP for the things in the centrifuge would effectively be towards the rotation axis). When you keep pouring (dirty) fluid inside it would fill that wall-lip enclosed volume, until it starts overflowing over the top lip (as the bottom is mostly** solid) Since the overflowing liquid will fly away horizontally not being stopped by anything else, there should be external housing - That ext. housing can be very simple as it's fixed, and the only special thing is on its bottom. The bottom should be separated in 3 areas: - inner-most: for passing the axis of the motor spinning the centrifuge (that could be dedicated motor, or a Dremel or whatever you find appropriate). - mid-area, separated by two vertical walls to prevent the fluid overflowing in the inner- or outer-most areas. That's where the remaining dirty fluid would drain when the centrifuge is stopped, thru the holes on the bottom of the "cooking pot". - and the outer-area, which would collect the (clean) fluid overflowing above the "cooking pot" top lip. The mid- and outer areas need one or more drain holes that lead to separate containers for the clean and remaining dirty fluids. The inner-most the hole for the motor's axis, isn't strictly necessary to be on the bottom, but it would be more convenient as the pouring of the dirty fluid would happen from the top. Bonus: if you pour the dirty fluid from the top straight down some of it might immediately drain thru the dirty fluid holes (before the centrifugal force pull it to the "pot" walls), or it might fly directly to the area near the overflow lip, and not have enough time in the centrifuge to let its heavier particulates to settle on the "pot" walls. To prevent that it would be idea to add a part that would serve as a channels for the dirty fluid, and at the same time as an umbrella for the dirty-fluid drain holes on the bottom of the "pot". It should be with at least two symmetrical arms (that should be plenty, but in any case it should be perfectly symmetrical to avoid introducing vibrations during high speed rotations). That part should be attachable to the center of the spinning "pot", at about the place there the motor's axis attaches, and should of course spin with the centrifuge "pot" in order to guide the dirty fluid towards the wall and bottom of the "pot". This way the newly introduced dirty fluid would have the longest path to go until it reaches the overflow lip, and thus will provide more time for the dirt particles to settle on the walls, and displace the already cleaned fluid over the lip. ** "bottom is mostly solid" - means that in a "cooking pot" solid bottom there should be few holes near the central rotation axis, which will allow the remaining (dirty) fluid to be drained thru these holes in a separate container, for future filtering. If you'd like you can add a lid over the fixed housing to prevent any fluid spraying around. Also the "pot" bottom could be a bit concave s o to guide easier the remaining dirty fluid to the drain holes on the bottom when the centrifuge is turned off. At rough calcs ~7cm radius spinning centrifuge "pot" at ~11300 RPM would produce ~10,000 g-force! So it doesn't need to be large - radius increases g-force linearly, but RPM increase g-force exponentially, and given that most motors can spin it around 6,000~10,000 (typical angle-grinders), or even near 35,000 for Dremels, the real limiting factor would be the spinning "pot" strength (of it's own weight + the operating fluid below the overflow lip) at the given RPM. And of course it would work fine at much lower RPM, just with lower effective g-force.
I'm so impressed by this liquid-piston engine! It's amazing to see how you've been able to use vodka as a fuel source. I've always thought that it was a waste to use vodka for getting people drunk, when it could be used for something so much more productive, like transportation. I'm really excited to see what you do next. I think there's a lot of potential for liquid piston engines to revolutionize the way we travel.
Could you try build an upgrade to an EDF that feeds it compressed air (like a jet engine without combustion.) It could be a pretty intresting thing to try.
wheres the compressed air coming from? and whats the point? yknow how jets can do mach 3, or better? and ducted fans can only do subsonic, at best, mach 0.8? its got nothing to do with how much air they shove through them, they cant accelerate the air past mach1. whereas the HEAT of the combustion in the jet engine is what allows the thing to get past that mach limit. refer to delaval nozzles... heat converting to kinetic energy.
@@paradiselost9946well the compressed air could simply come from a compressor at the top of the duct. It would in theory push speed limit while still being efficient because more air is being pushed backwards for the same energy input. For the same reason the max ceiling of it would be increased dramatically.
@@TheWorstBridger terrible. if theyre strapped to the ground, or if one measures fuel consumption for the air consumed. but strapped to a plane, doing 5000km/hr, so the plane only flies for 45 minutes to fly 3000km, rather than taking 4.5 hours at say, 660km/h, and the total fuel used in that flight time is accordingly reduced and when one considers efficiency merely as "fuel consumed per kilometer travelled" then the jet is far more efficient than any other option. or that the prop plane with normal engines also taking 4.5 hours to travel the same distance, despite having engines with better efficiency when tested on a stand, has far lower efficiency when it has to struggle with air density, air friction, and general losses in the propellor. an engine is only as good as the prop attached to it. yet that same prop engine flying along at 300km/h would be better efficiency. if it had to pull a large load up, like a crop duster. or a hercules. dont see jet powered crop dusters... the jet doesnt give a damn as its "propellor" is an integral part of its fundamental operation. its only job is suck air in, heat it up, use some of the heat to drive itself, and using the remaining heat to accelerate air to a higher velocity than possible if merely "compressed". again. delaval nozzles. converging diverging nozzles. the conversion of thermal energy to kinetic energy. maybe you are confused because noone ever explains jets as using heat, they just say "they push air out back fast"? words like "enthalpy" and "adiabatic expansion" scare you?
The Mazda 787b had an inverted rotary like that, and the way the go kart sounds has a lot of similarity to how that 787b sounded. That's awesome that a little kart has that much acoustic presence about it.
Liquid piston combustion to drive the permanganate H2O2 reaction rather than pushing a syringe with your hand would be pretty cool. Kind of like driving a bigger thrust with a minor combustion, like when you used the linear PDE to start the RDE!
Man I missed this channel and I’m glad it’s back. This is one of the best sponsored videos because it actually relates to the content you normally produce.
@@dash0173 Well the past couple years he has been uploading 1 video a month, so after 3 months I was getting worried. Hopefully he got some good time off to relax during this summer as he deserves it.
Well A: it honestly looks like you had an absolute blast doing this and made me wanna do what you do. You just hung out with some engineers all day and built stuff. Awesome! B: see how fast you can make it go!
The problem with using liquid based Piston is that liquid tend to change its behavior in different states. Like under to much pressure it can change into a Gas or superfluid or other way around. And since it can change it state it will be able to find was out of the Chamber even if its the smallest crack or similar. Its a good idea in General to have one less mechanical Part but this could be only useful for small engines. Everything higher will just make alot more problems than solving some.
The Wenkel rotary engine is amazing but problematic for daily use driving. It recently got a new life in a Toyota as a range extender. Exciting and fun stuff!
I love your propulsion videos! You should try working with NileRed to build a nitric acid rocket engine. With any luck, the tomatoes could catch fire spontaneously!
@@enolopanr9820 I was just thinking about how compact the engine was and how flexible the fuel was. It would seem to be a good generator in an emergency.
@@enolopanr9820MX-30 R-EV. They're calling it a plug in hybrid, but it's a range extended EV... with no range. It's got a *tiny* battery that's constantly recharged by a small rotary engine.
The reason we don't use wankles is because unit cost is high.. tolerance needs to be tight and they need complex maintenance because (especially in 2stk) they are very complex. Until you solve these issues it is just some fancy wankle.
You could make an motor which is very powerful and quite, it would benefit the environment a lot no air pollution or sound pollution, it would be great.
Hey, love your channel! I'd be thrilled if you took on a project involving the Free-Piston Engine, a truly exotic design. It's a fascinating approach to internal combustion with no conventional crankshaft, and it's a design that holds significant potential for hybrid electric vehicles. I think your viewers would appreciate the uniqueness of this concept, and I'm certain you could make some interesting modifications to boost its efficiency and practicality. Looking forward to seeing what you come up with next!
I’m most interested in seeing how this comes to market and what types of maintenance will be required to keep this motor running. Like does it use spark plugs or some other form of piezo technology? And how is it lubricated?
You should do a video on ducted fuel injection for Diesel engines. It has the potential to make an already efficient engine 10x more efficient. A lot of truck companies are researching it and in theory it can be retrofitted to any diesel car.
10x more efficient means what? A 90% reduction in losses? That would be from 66% to under 7%. Dude, a 93% efficient engine is impossible. 70% is pushing things, and a rotary design is just too inefficient to break 2/3 efficiency. Too much surface area, both for friction and thermal losses.
You should do a video comparing adding scale to that engine vs putting multiple of the chambers in series like you see with wenkels 2 or 3 or more rotor engines. It'd be cool to see which is more efficient use of space/weight for the power output.
This whole video is just an ad for the company and then he states in the title that he built an engine which didnt happen. I hope there will come more about this because waiting 3 months just for a half interresting advertisment is kinda disappointing.
It would be interesting if you could build a bigger version on this engine to incorporate it in a bigger project. You could also have multiple ones if having one big engine isn't possible.
Make your 3D print in foam and use it as a mold to create a negative mold in concrete, then melt the foam with some molten metal to make your rocket engine or combustion engine more resilient.
I don’t know if you have worked with cannons before but I really do think they are a cool concept. Maybe you could try to make it steam powered or air powered. Heck, you could maybe use the elephant toothpaste reaction even. This could also be a cool and effective way to destroy tomatoes lol
Rotary engines are amazing, lightweight,great power in compact size and sounds better than anything else,i do really hope some design fix all the problems and start having all type of vehicle with rotary...
Itd be very interesting to see you try to incorporate some of the past designs like the jet engines into something more like this. To see the concept is very cool but see it working like with the scooter is just taking it a step further! Im sure there is someone in your area who would join in on projects like that.
I want to see more about your liquid piston engine. Also, I fail to see how this rotary engine uses a liquid piston. Did they just adopt the company name and give up on developing the namesake product?
Video idea: using a bigger version of one of your compressed air engines (preferably the triangle one) power a normal bicycle turning it into a compressed air engine powered bicycle. Not sure if this is possible but hopefully it is Thank you for another amazing video @integza
Hello Integza! I've seen your ion thrusters and I think it would be a great idea to upgrade and install them to a skateboard or to a rc boat. I am very curious to see how this engine technology can do against other engine types that you've built by using them to a practical demonstration and compare their thrust level.
I'm 58, lived on this planet most of my life, still looking forward to leaving, although once in awhile, I watch something, read something, see something, hear something, touch something, taste something, stand on something, pick up something and these things make me want to stay a little longer. Still trying to figure out why. Strange Planet you have here. Like I say "Nice place to visit, but I sure would not want to live there" Still............I am enjoying my visit, maybe we have coffee someday?
I have heard rumor of they have learned how to make a superconductor that is stable and atmospheric pressure and temperature. They're said to haveing done this by combining a mixture of the carbons off of lead and copper. I think your next video should be on can you make this superconductor material
The thing that's absolutely fascinating to me about the Humphrey Pump is that it ran around 20% fuel efficiency. Using a 70% conversion for a simple hydro turbine that's less concerned with particulate matter like a segner turbine would leave you around 14% thermal efficiency. Certainly nothing that'll reinvent power production as an industry but nevertheless interesting for off-grid or remote purposes. That'd be an incredibly simple machine made out of very simple components with little downtime.
That is incredibly cool! I am happy to see someone try something new. Perhaps this will be in future cars as an alternative to battery electric. Of course, there are lots of other uses for this as you pointed out. Generators and things that don't necessarily need to be on a moving vehicle.
Love your videos!!! Always make my day! You should try making a 3d printed version of a Hydrogen engine! (low fuel consumption of, be careful) and SMASH THOSE TOMATOES

I've been around your channel for a couple of years. ik how much you love engines and how you progressively got better at making them. This could be a hard hobbyist model and you may fail.. but hey, what better way is there to live? I wait every month just to hear those 3 words haha. "Tomatoes are disgusting!"
It is good to see that people still have a spirit of adventure, in Australian culture, you are my type of Nerd. It is a pity that my country has let most of it’s brains go to other countries.
How about a way to combine a solar cell, Stirling engine, and a thermo electric cooler, and see how long they can run, and 3d print as many parts as you can. And maybe use the rotational energy to smash some tomatoes (my son would love to see tomatoes get smashed in a cool way)
Years later it's still in development and of course like all new engine concepts it's only used in military but they promise it will be something revolutionary to attract investors.
It would be awesome if you try to build a ramjet engine. I think it's possible considering you have all the necessary proprietary knowledge from building all sorts of other jet engines. Great video as always!
Hello, you can use the combustion chamber of the small jet engine and the turbine of the small jet engine and the propellers to suck the front air, then mix the fuel in the combustion chamber and oxygen with the air that enters the engine.
I would love to see you design and make a briefcase 3D printer. I have very limited space in my house and would love to be able to pull out a briefcase, open it up and start printing, anywhere, anytime.
Have u thought about doing an interview with Bob Lazar? Although Bob is know for working at a certain area he is also a creative person who converted his corvette to run on hydrogen and that was back in 1989 so like I said he would b a very interesting guy for u to interview. There is also a guy who was the VP of G.M back in the late 90s to mid 2000s who has built this Red Hot Rod Truck with 500hp that runs on Hydrogen that u should also checkout and that truck is a recent build and was shown at SEMA. I think it would b very interesting for both of those men to Che k out each other's car and how they went about solving certain problems that each car had to deal with to get to work.
I would love to see this engine as a diesel range extender for the electric bikes currently being used by the military. You could shave a non-trivial amount of weight from the battery and use the airflow to pump heat out of the motor.
If it's got such problem to slow idle it only means that seals are leaking a lot of compression, or perhaps something like power valve (additional throttle on the exhaust side) would sort it out. Most likely the carb was not properly adjusted on top of that - it sound to me like running too lean - sucking too much air.
I would love to see this motor in 2 different forms. One as an small HP outboard engine for a dinghy, and 2, I'd like to see it as a diesel. I live on a sail boat and would absolutely love to see this technology be adapted to it

This engine just does not have the breathing room to meet the claims they're proposing, I don't think the 2-stroke will fare much better either; the military was sold an underpowered go-kart engine.
@@Maccaroney Wasn't the limitor in the video the transmission gear ratio and not the engine itself? The engine was red lining at 9k RPM, and thus could not accelerate any further. Engine RPM could not be reduced because there was no higher gear to put in. That does not seem like a engine drawback but rather a design drawback of the scooter.
@@timerertim yes but acceleration up to redline is why i made that judgement.
Its always a good day when we get to see Integza making things

Yep. Will keep hanging on.
We need that Tomato Power Plant up and running.... Go Tomato Electric Zap......
Would be wild to see a bigger version of one of these motors in a race bike
How about you try to build different types of engines and see how much electricity you can generate / how efficient they are. Great stuff as usual!

Your comment is super far down despite having as many likes as it does?
@@chubsythedog2325Yeah innit
Seeing that your area of interest is predominantly in propulsion methods, I would quite like to see you mount some kind of lightweight air breathing engine to an airframe that would allow it to fly under its own propulsion, maybe something like the old V1s?
You just invented jet plane
he made those engines and the thrust could barely carry the engines mass alone
Holy cow, the engine itself was cool and blew me away, the fact it can run on moonshine was exhilarating!
you might be surprised most engines can run on any liquid that burns, for a while at least. People run their cars on vegetable oil.
a conventional engine can run on Moonshine too. just gotta inject enough fuel and have the right amount of air in a combustible mixture for it to run. as the other comment says if it can be attomized and burn in a exlosive state (ie burn fast enough) then an engine can run on it. i had a HOBBY nitro OS engine running on methylated spirits. (which is literally moonshine with denaturing agent so you can't drink it) it usually a 60% ethanol water mixture
Exhilarating? More like intoxicating ;)
@@thewhitefalcon8539 Uh, leeet's modify that: Some engines can run on anything that burns that has a high enough octane rating to not spontaneously auto ignite during the compression phase, and some engines can run on any hydrocarbon that isn't too thick to go through the injection nozzles. Trying to run a diesel engine on alcohol gets you nowhere, and trying to run a gasoline engine on cooking oil gets you nowhere.
This engine is amazing
i would be interested to see how the power stacks up against a rotaty engine of the same size
Thinking the same thing and I mean the same problems that plagued the 4 stroke wankel prob gonna pop up
@@henrygoldberg1248I don't think the Wankel Rotary ever is considered 4 stroke. It hasn't really got any problems though.
It would be. Especially given there were countless ideas to make them into generators as well. Sadly they never got the interest. Much like the Wankel Rotary, this Liquid Piston company is going to face the same issues as Mazda. Having the technology is one thing, it takes research and endless investment to shift it even if your product can be superior..
@@henrygoldberg1248 I've been watching them for quite a few years. This resolves the issues the Wankel had with the apex seals and such.
@@thetboliproject2890 The biggest single problem the Wankel faced was unburned hydrocarbon emissions from the need to inject oil for apex lubrication and the long combustion chamber which made complete combustion a problem. Durability was not an issue.
It's been great watching how your channel has grown, going from doing sketchy 3d printed engines to here.
And as always, this video was a great watch. Looking forward to the next one
Stack 2 or 3 of those and you've got your Go-Kart engine! Just have to mind the timing to get best torque. Glad to see a working prototype. I hope they're successful.
Now that I've seen this engine actually work, my confidence in them has gone up immensely. I feel like their biggest hurdle is gonna be cooling, like the original Rotary Mazda made. But, I'm not an engineer.
That's the problem with the liquid piston design. They can't be stacked like wankle rotary engines can. honestly a lot of what is claimed about this engine seems like a lot of snake oil to me. I was excited when I first saw this engine and I still haven't seen one running that makes the kind of power that they claim it should.
@@bz938Actually, it can. If you design the exhaust manifolds to be similar to those of a Supercharger, you can actually get the exhaust fumes out without affecting the Engine intake.
Stop trying to claim something is "Impossiberu", when you have not tried it yourself.
@@Victor-056 it's definitely not impossible but the way the intake and exhaust are currently configured won't allow the engine to be stacked. They can be done with modifications but it may not be as compact as a larger single rotor.
The design works and that is something to be proud of.
What I don't like is how the designer talks about inventing a new revolutionary kind of cycle. This is clearly still an otto cycle engine.
@bz938 or hooking 2 up to a differential to stack the power like most hybrids use.
that way you could theoretically have one half stop running, or run slower in situations where you don't need power from both engines.
It's definitely about the journey! Doesn't matter what the subject is, it's your approach to the problem, the attitude towards finding a solution, and fun you have doing it that bring me back for the next video.

Would love to see this in a model plane, how much more flight time you'd get if it's smaller and lighter
You can get Wankels for model planes. I remember seeing one back in the 90s. I had a really unique sound but it was hellishly expensive
@SimonHowroyd not much has changed. There's a Chinese company making liquid cooled ones for cars now, and a twin rotor one too. Stupid expensive, but well worth it.

I have always been interested in seeing how a Stirling engine would work if you use a manual CVT gearbox as a throttle control, so there's an idea for you to try.
Holy, this is awesome! It's companies like this that need support and adoption to move things forward. This isn't some on paper only idea the fact there is running testable engines and their confidence in them to let you mount it, run vodka through it and just go nuts is some levels of transparency I've never seen! Please do a follow up with theses guys at a later time. As usual learned something new and had a lot of fun watching it. Keep up the great work.
Well, I don't know about the performance aspects...but the sound characteristics are fantastic! They sound awesome.
I was just going to comment the same. A really good sounding engine.
sounds exactly the same as the 3-cylinder 675cc Triumph
Just a bit worrying hearing “investing” and “15% discount” in the same sentence
Invester stock options plan. So when they go public you'll see %15 profit even before there IPO. This has promise for drone hybrid car technology. The sealed bearing is the one drawback,but a workaround will materialize.
I love how widespread and interesting your videos can be and how well you explain the concepts of the designs of machines you build
What a great opportunity for you to meet with the team and learn so much directly! It’s been great watching the channel grow!
Id like to see you pair up a 3 phase generator to a liquid piston engine and test it for output.
How about making this an overunity pulsed plasma 2 stroke like Joseph Papp's pulsed plasma 2 stroke engine did. This tapped aetheric ZPE. i just dont understand the obession of burning somethihg to make power.
Anything crazy is a good swap for my miata lol
I absolutley love the sound of it it's like a 3 cylinder, I hope they release a 10hp version just so people can play with rotaries again I would honestly throw one on my go kart
I just love the way it sounds, almost like a combination of a two-stroke inline twin and two-stroke inline three.
yeah, now they only need to put expansion chambers on the exhausts
Hey Integza, I had a video idea for you. I saw an article the other day about a 3d printed peristaltic pump, and I thought it would be fun to see you replicate that and see what you can do with the ability to move fluids around!
Here's an idea for a future video - make a centrifuge for filtering heavier particles from a fluid - for example dirt from oil, or resin particles from alcohol (that are most often used in resin 3D printing).
The main part is something like a cooking pot, but with additional lip on the top rim. That lip could be something like 2 or 3 cm, and when spinning it would trap fluid on the inner walls in the volume closed by that lip. (the UP for the things in the centrifuge would effectively be towards the rotation axis).
When you keep pouring (dirty) fluid inside it would fill that wall-lip enclosed volume, until it starts overflowing over the top lip (as the bottom is mostly** solid)
Since the overflowing liquid will fly away horizontally not being stopped by anything else, there should be external housing - That ext. housing can be very simple as it's fixed, and the only special thing is on its bottom. The bottom should be separated in 3 areas:
- inner-most: for passing the axis of the motor spinning the centrifuge (that could be dedicated motor, or a Dremel or whatever you find appropriate).
- mid-area, separated by two vertical walls to prevent the fluid overflowing in the inner- or outer-most areas. That's where the remaining dirty fluid would drain when the centrifuge is stopped, thru the holes on the bottom of the "cooking pot".
- and the outer-area, which would collect the (clean) fluid overflowing above the "cooking pot" top lip.
The mid- and outer areas need one or more drain holes that lead to separate containers for the clean and remaining dirty fluids.
The inner-most the hole for the motor's axis, isn't strictly necessary to be on the bottom, but it would be more convenient as the pouring of the dirty fluid would happen from the top.
Bonus: if you pour the dirty fluid from the top straight down some of it might immediately drain thru the dirty fluid holes (before the centrifugal force pull it to the "pot" walls), or it might fly directly to the area near the overflow lip, and not have enough time in the centrifuge to let its heavier particulates to settle on the "pot" walls.
To prevent that it would be idea to add a part that would serve as a channels for the dirty fluid, and at the same time as an umbrella for the dirty-fluid drain holes on the bottom of the "pot".
It should be with at least two symmetrical arms (that should be plenty, but in any case it should be perfectly symmetrical to avoid introducing vibrations during high speed rotations).
That part should be attachable to the center of the spinning "pot", at about the place there the motor's axis attaches, and should of course spin with the centrifuge "pot" in order to guide the dirty fluid towards the wall and bottom of the "pot".
This way the newly introduced dirty fluid would have the longest path to go until it reaches the overflow lip, and thus will provide more time for the dirt particles to settle on the walls, and displace the already cleaned fluid over the lip.
** "bottom is mostly solid" - means that in a "cooking pot" solid bottom there should be few holes near the central rotation axis, which will allow the remaining (dirty) fluid to be drained thru these holes in a separate container, for future filtering.
If you'd like you can add a lid over the fixed housing to prevent any fluid spraying around.
Also the "pot" bottom could be a bit concave s o to guide easier the remaining dirty fluid to the drain holes on the bottom when the centrifuge is turned off.
At rough calcs ~7cm radius spinning centrifuge "pot" at ~11300 RPM would produce ~10,000 g-force!
So it doesn't need to be large - radius increases g-force linearly, but RPM increase g-force exponentially, and given that most motors can spin it around 6,000~10,000 (typical angle-grinders), or even near 35,000 for Dremels, the real limiting factor would be the spinning "pot" strength (of it's own weight + the operating fluid below the overflow lip) at the given RPM.
And of course it would work fine at much lower RPM, just with lower effective g-force.
This way enrichment lies
Lost wax casting would be a really cool thing to see you try! I do it for my job and it's a very unique process.
I'm so impressed by this liquid-piston engine! It's amazing to see how you've been able to use vodka as a fuel source. I've always thought that it was a waste to use vodka for getting people drunk, when it could be used for something so much more productive, like transportation.
I'm really excited to see what you do next. I think there's a lot of potential for liquid piston engines to revolutionize the way we travel.
Wow 😁 its exhilarating to see an engine working with just basic principles of fluid mechanics.. it's very awesome to watch ...
You should do a video about two-stroke engines. Especially the expansion chamber portion. It seems right up your alley!
Could you try build an upgrade to an EDF that feeds it compressed air (like a jet engine without combustion.) It could be a pretty intresting thing to try.
wheres the compressed air coming from?
and whats the point?
yknow how jets can do mach 3, or better?
and ducted fans can only do subsonic, at best, mach 0.8?
its got nothing to do with how much air they shove through them, they cant accelerate the air past mach1.
whereas the HEAT of the combustion in the jet engine is what allows the thing to get past that mach limit.
refer to delaval nozzles... heat converting to kinetic energy.
@@paradiselost9946well the compressed air could simply come from a compressor at the top of the duct.
It would in theory push speed limit while still being efficient because more air is being pushed backwards for the same energy input. For the same reason the max ceiling of it would be increased dramatically.
@@paradiselost9946and would you mind telling me how efficient those jets are by the way
@@TheWorstBridger terrible. if theyre strapped to the ground, or if one measures fuel consumption for the air consumed.
but strapped to a plane, doing 5000km/hr, so the plane only flies for 45 minutes to fly 3000km, rather than taking 4.5 hours at say, 660km/h, and the total fuel used in that flight time is accordingly reduced and when one considers efficiency merely as "fuel consumed per kilometer travelled" then the jet is far more efficient than any other option.
or that the prop plane with normal engines also taking 4.5 hours to travel the same distance, despite having engines with better efficiency when tested on a stand, has far lower efficiency when it has to struggle with air density, air friction, and general losses in the propellor.
an engine is only as good as the prop attached to it.
yet that same prop engine flying along at 300km/h would be better efficiency. if it had to pull a large load up, like a crop duster. or a hercules. dont see jet powered crop dusters...
the jet doesnt give a damn as its "propellor" is an integral part of its fundamental operation. its only job is suck air in, heat it up, use some of the heat to drive itself, and using the remaining heat to accelerate air to a higher velocity than possible if merely "compressed".
again. delaval nozzles. converging diverging nozzles. the conversion of thermal energy to kinetic energy.
maybe you are confused because noone ever explains jets as using heat, they just say "they push air out back fast"? words like "enthalpy" and "adiabatic expansion" scare you?
The Mazda 787b had an inverted rotary like that, and the way the go kart sounds has a lot of similarity to how that 787b sounded. That's awesome that a little kart has that much acoustic presence about it.
Liquid piston combustion to drive the permanganate H2O2 reaction rather than pushing a syringe with your hand would be pretty cool. Kind of like driving a bigger thrust with a minor combustion, like when you used the linear PDE to start the RDE!

@@dash0173 Well the past couple years he has been uploading 1 video a month, so after 3 months I was getting worried. Hopefully he got some good time off to relax during this summer as he deserves it.
Well A: it honestly looks like you had an absolute blast doing this and made me wanna do what you do. You just hung out with some engineers all day and built stuff. Awesome!
B: see how fast you can make it go!
The problem with using liquid based Piston is that liquid tend to change its behavior in different states. Like under to much pressure it can change into a Gas or superfluid or other way around. And since it can change it state it will be able to find was out of the Chamber even if its the smallest crack or similar. Its a good idea in General to have one less mechanical Part but this could be only useful for small engines. Everything higher will just make alot more problems than solving some.
The Wenkel rotary engine is amazing but problematic for daily use driving. It recently got a new life in a Toyota as a range extender. Exciting and fun stuff!
That seems like some really cool tech! Hope the company gets more successful
I love your propulsion videos! You should try working with NileRed to build a nitric acid rocket engine.
With any luck, the tomatoes could catch fire spontaneously!
I like the idea of a rotary-powered generator. It would be nice to see the engine perform useful work at lower rpm's.
i am getting flashbacks to the glory days of mazda. If mazda took something similar to this and ran with it we could get one in a production car again
@@enolopanr9820 I was just thinking about how compact the engine was and how flexible the fuel was. It would seem to be a good generator in an emergency.
@@enolopanr9820MX-30 R-EV. They're calling it a plug in hybrid, but it's a range extended EV... with no range. It's got a *tiny* battery that's constantly recharged by a small rotary engine.
The reason we don't use wankles is because unit cost is high.. tolerance needs to be tight and they need complex maintenance because (especially in 2stk) they are very complex.
Until you solve these issues it is just some fancy wankle.
It sounds like a triple cylinder 2 stroke! It just sounds really cool!
Been following you for years and your content is always so informative and entertaining - it saves me from the crap on youtube shorts
You could make an motor which is very powerful and quite, it would benefit the environment a lot no air pollution or sound pollution, it would be great.
This is the kind of videos I love watching at 3:40 am
Hey, love your channel! I'd be thrilled if you took on a project involving the Free-Piston Engine, a truly exotic design. It's a fascinating approach to internal combustion with no conventional crankshaft, and it's a design that holds significant potential for hybrid electric vehicles. I think your viewers would appreciate the uniqueness of this concept, and I'm certain you could make some interesting modifications to boost its efficiency and practicality. Looking forward to seeing what you come up with next!
With a bit of tuning, even a normal piston engine can run on alcohol. It runs a lot hotter and takes a good bit of tuning, but it sure works!
I’m most interested in seeing how this comes to market and what types of maintenance will be required to keep this motor running. Like does it use spark plugs or some other form of piezo technology? And how is it lubricated?
You should do a video on ducted fuel injection for Diesel engines. It has the potential to make an already efficient engine 10x more efficient. A lot of truck companies are researching it and in theory it can be retrofitted to any diesel car.
10x more efficient means what? A 90% reduction in losses? That would be from 66% to under 7%. Dude, a 93% efficient engine is impossible. 70% is pushing things, and a rotary design is just too inefficient to break 2/3 efficiency. Too much surface area, both for friction and thermal losses.
You should do a video comparing adding scale to that engine vs putting multiple of the chambers in series like you see with wenkels 2 or 3 or more rotor engines. It'd be cool to see which is more efficient use of space/weight for the power output.
It sounds like a Honda Beat! Imagine making it 660cc?!
Such a high quality video. easily worth the wait
This whole video is just an ad for the company and then he states in the title that he built an engine which didnt happen. I hope there will come more about this because waiting 3 months just for a half interresting advertisment is kinda disappointing.
This reminds me of how a pop-pop boat works, the difference being that the liquid isn't fully enclosed.
The fact that is can run on vodka is both surprising and actually quite promising considering how easy it is to make.
It would be interesting if you could build a bigger version on this engine to incorporate it in a bigger project. You could also have multiple ones if having one big engine isn't possible.
make a plane with the LIQUID PISTON ENGINE
Make your 3D print in foam and use it as a mold to create a negative mold in concrete, then melt the foam with some molten metal to make your rocket engine or combustion engine more resilient.
Video Idea: you sould build a nitinol engine that if you would put in warm water than it would run!!!
I don’t know if you have worked with cannons before but I really do think they are a cool concept. Maybe you could try to make it steam powered or air powered. Heck, you could maybe use the elephant toothpaste reaction even. This could also be a cool and effective way to destroy tomatoes lol
Rotary engines are amazing, lightweight,great power in compact size and sounds better than anything else,i do really hope some design fix all the problems and start having all type of vehicle with rotary...
Itd be very interesting to see you try to incorporate some of the past designs like the jet engines into something more like this. To see the concept is very cool but see it working like with the scooter is just taking it a step further! Im sure there is someone in your area who would join in on projects like that.
I want to see more about your liquid piston engine. Also, I fail to see how this rotary engine uses a liquid piston. Did they just adopt the company name and give up on developing the namesake product?
Its looks like a rotary and sounds cool too,would love a comparison on how they perform
Video idea: using a bigger version of one of your compressed air engines (preferably the triangle one) power a normal bicycle turning it into a compressed air engine powered bicycle.
Not sure if this is possible but hopefully it is

I would love to see you do a video on a magneto-plasma dynamic thruster, it is a really interesting kind of propulsion system.
1st step is finding a big enough vacuum chamber!
I have heard rumor of they have learned how to make a superconductor that is stable and atmospheric pressure and temperature. They're said to haveing done this by combining a mixture of the carbons off of lead and copper. I think your next video should be on can you make this superconductor material
The thing that's absolutely fascinating to me about the Humphrey Pump is that it ran around 20% fuel efficiency.
Using a 70% conversion for a simple hydro turbine that's less concerned with particulate matter like a segner turbine would leave you around 14% thermal efficiency.
Certainly nothing that'll reinvent power production as an industry but nevertheless interesting for off-grid or remote purposes. That'd be an incredibly simple machine made out of very simple components with little downtime.
I think it's time for you to make a rocket propelled RC submarine, extra points for an explosive warhead and some underwater tomatoes!
finally a good use of spirytus rektyfikowany :) greeting from Poland!
That is incredibly cool! I am happy to see someone try something new. Perhaps this will be in future cars as an alternative to battery electric. Of course, there are lots of other uses for this as you pointed out. Generators and things that don't necessarily need to be on a moving vehicle.
Love your videos!!! Always make my day! You should try making a 3d printed version of a Hydrogen engine! (low fuel consumption of, be careful) and SMASH THOSE TOMATOES

Wow coming back to this it’s incredible how much like a 3 cylinder this engine sounds like
ngl, it sounds so sick, like an actual superbike.
Create a Muzzle to supress the sound of the engine to make it quiter for normal or public use. you can also sell this for public.
Your videos are very much informative and with lot of technical content useful for engineers to understand physics and science. LiquidPiston is going to be industry leader, game changing!

How about a way to combine a solar cell, Stirling engine, and a thermo electric cooler, and see how long they can run, and 3d print as many parts as you can. And maybe use the rotational energy to smash some tomatoes (my son would love to see tomatoes get smashed in a cool way)
Superb channel. The engines sounds bloody great.
I'm a mechanical engineer student, and your videosss my mannn inspires me more to master & learn my majorrr, thank you!
Years later it's still in development and of course like all new engine concepts it's only used in military but they promise it will be something revolutionary to attract investors.
It would be awesome if you try to build a ramjet engine. I think it's possible considering you have all the necessary proprietary knowledge from building all sorts of other jet engines. Great video as always!
So cool if you to cover Liquid Piston! I’ve been following them for awhile and am really excited about what they could deliver in the future!
Hello, you can use the combustion chamber of the small jet engine and the turbine of the small jet engine and the propellers to suck the front air, then mix the fuel in the combustion chamber and oxygen with the air that enters the engine.
I would love to see you design and make a briefcase 3D printer. I have very limited space in my house and would love to be able to pull out a briefcase, open it up and start printing, anywhere, anytime.
i had no idea they had fully functioning liquidpiston engines. here's to hoping they live up to the hype!
Have u thought about doing an interview with Bob Lazar?
Although Bob is know for working at a certain area he is also a creative person who converted his corvette to run on hydrogen and that was back in 1989 so like I said he would b a very interesting guy for u to interview.
There is also a guy who was the VP of G.M back in the late 90s to mid 2000s who has built this Red Hot Rod Truck with 500hp that runs on Hydrogen that u should also checkout and that truck is a recent build and was shown at SEMA.
I think it would b very interesting for both of those men to Che k out each other's car and how they went about solving certain problems that each car had to deal with to get to work.
I think that a video on regenerative braking would be super cool. Tom Stanton has a really nice eBike, maybe give him a call.
I would love to see this engine as a diesel range extender for the electric bikes currently being used by the military. You could shave a non-trivial amount of weight from the battery and use the airflow to pump heat out of the motor.
If it's got such problem to slow idle it only means that seals are leaking a lot of compression, or perhaps something like power valve (additional throttle on the exhaust side) would sort it out. Most likely the carb was not properly adjusted on top of that - it sound to me like running too lean - sucking too much air.
If this is small and lightweight it could be a godsend for general aviation, as a new powersource for light aircraft has not been had in 80 years!
I would love to see this motor in 2 different forms. One as an small HP outboard engine for a dinghy, and 2, I'd like to see it as a diesel. I live on a sail boat and would absolutely love to see this technology be adapted to it
How many of those engines would it take to move a car also could u use the exhaust recycle to power the motor
