[@piperg6179]

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.

[@timerertim]

@@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.

[@blueckaym]

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.

@@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.

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.

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.

[@bulleqc1520]

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.

[@coalburn7916]

i had no idea they had fully functioning liquidpiston engines. here's to hoping they live up to the hype!

[@tyler1988]

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.

[@RichardBronosky]

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?

[@quyle9483]

It sounds like a triple cylinder 2 stroke! It just sounds really cool!

[@caz0011666]

I think it's time for you to make a rocket propelled RC submarine, extra points for an explosive warhead and some underwater tomatoes!

[@emilpriftaj4642]

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.

[@scottpeterson4888]

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.

[@TheNynrahGhostJo]

I would love to see you do a video on a magneto-plasma dynamic thruster, it is a really interesting kind of propulsion system.

[@muzzdeni28]

1st step is finding a big enough vacuum chamber!

[@mas13ish1]

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.

[@cruzcam]

This is the kind of videos I love watching at 3:40 am

[@elinviljoen7139]

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

[@Cheebzsta]

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.

Yeah... im not investing in a IC company

[@JH2000Gameplay]

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.

[@oldschoolcfi3833]

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!

[@stumpr1]

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?

[@vincentjugah4563]

I'm a mechanical engineer student, and your videosss my mannn inspires me more to master & learn my majorrr, thank you!

[@sinoverlord409]

I love engineers and scientists who think outside the box and don't conform to what others consider to be normal

[@santoshKhadasare]

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!

[@joeltranformer]

Its looks like a rotary and sounds cool too,would love a comparison on how they perform

[@Zoëlle.Kawaii]

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.

[@SkyHikerMike]

Man I want one of these on my paramotor… it would be a serious game changer!

[@RobertoTheRobit]

The motor is really cool! How about a video where you DIY a fix wing drone with FPV and a jet engine?

[@danielhemp387]

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)

[@Deriko31]

I always wanted to see a Recreation of the Chrysler Turbine engine, I mean , Dude! A frigging weird reaction turbine on a car. Those engines never took off because of the high consumption and noise but were reliable and smooth.

[@302redirect]

RAMJET ENGINE PLEASEEEEEEE!!! I don't care if I win or not. I just want Integza to read this comment! 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!"

[@klp1tyklop261]

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...

[@louisanderson6375]

Cool video..wish Liquid Piston success with their engine!

[@jqmark]

I wish they would release the 50HP engine. It's so tiny and light it would be great to have one of those to stick in anything with wheels or a prop or maybe tracks well anything,

[@sandmancase9]

[@VincenzoBarbato]

these guys kind of remind me of those HHO guys back in the late 90s early 2000s 🤣🤣🤣, if you know, you know

[@supernova874]

That Vodka as a fuel 🤣 wtf awesome experimentation 😍

[@bradparker716]

Oh no he said every machinist's trigger word: Inconel

[@SkittishWrath]

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.

[@gasmaskexe231]

you should try and collab with ElectroBoom. Your combined chaotic energy should result in some amazing projects

[@kenphileh]

Superb channel. The engines sounds bloody great.
