scotty... You should do a video on the new "Omega 1" engine. It looks really promising.
🤣
@@calholli Will there also be an Omicron and/or Delta variant?
Scotty, you're good to go buddy!!
@@Xingqiwu387 Look it up-- it's an interesting design.
Mazda refuses to give up on this idea and there's something admirable about that.
Yeah, it is called bullheaded.
in the scheme of things, its not admirable in any way. They havent fized its issues in the many decades they've been running with the concept. It was a cool engine while it new, but it was dead out the gate... I rather liked the idea myself, but the LP engine is superior in every way.
@@user-bi7nq4nj7q doesn't really have any issues it's just they build them cheap
@@user-bi7nq4nj7q what issues?
The first patent for this engine design was by Felix Wankel in 1929, it was later used in the NSU Ro 80 from 1967/77 and was never successful. I worked for an NSU dealer in the UK at the time.
Love him or hate him, you really have to admire how intelligent and inquisitive Scotty Kilmer is. Even at his age hes still learning and sharing his knowledge. True philosophical
I like this liquid piston engine. As a former Mazda owner , I always thought there should have been a rotary option for the Miata.
That would have cannibalized sales of the RX-8. No manufacturer w/ any sense does that to themselves.
@@nunyabidniz2868 Never liked the RX-8. Former 1987 RX-7 owner.
@@WALTERBROADDUS I owned a 1971 or 2 Mazda RX-2. I loved the power and the 4 speed. That's after I finally found a Mazda dealer that knew how to stop the endless backfiring. (Hollywood Mazda) It liked to do that when I drove through the old, original Pasadena Fwy. with its series of arched tunnels. Other drivers threw me some very dirty looks.
@@ronlheureux7623 I think this new rotary engine offers a lot of Promise over the Wankel. It's power-to-weight ratio and compact size makes it a very attractive power plant. Not everybody wants to drive a Econo box or an SUV. I mean anybody who complains about fuel economy no, has never been to a Dodge dealership.🤣 When it ran well, the RX-7 was a great car. The cold start flooding was a pain though. 😞
That would be perfect.
The X-engine (liquid piston) seems like a good engine to be used on motorcycles. Small, light but can pack a lot of performance
That would be cool asf
Yes please
High revving also
The torque values also fit with what you'd want - the only issue is the way the torque drives the tires in low-grip situations.
Crossplane in-line 4s, V-twins and big-bang V4s essentially operate by providing small bursts of torque rather than a continuous drive. This makes a huge difference with grip at the limits (think reverse ABS). I don't know what the characteristics of this kind of engine would be, but if it operates similarly then it'd be great!
A modern superbike packs 215 hp and 83 lb-ft between 12 500 and 14 500 rpm while weighing 445lbs. How can you possibly wants more performance?
We’ve been waiting for the Rotary engine to come back for the longest time 🥲
I haven't.
No one wants a rotary engine car that required more maintenance than necessary.... Thats what project cars are for.
@@bign1667 enthusiasts r still hunger for rotary engine tho
@@bign1667 I've done like nothing to my car besides replace light bulbs, tires, and coil packs. Any other car you have me driving pedal to the metal redlining it all the time I'd have blown them to pieces by now, but not the RX-8. Biggest maintenance? Change the oil when I remember to, and premix. Yeah, that's not exactly crazy difficult (and you can get a SOHN adapter so you don't even have to pre-mix, just makes it separate oil tank like some dirt bikes or DEFT fluid in diesels)
@@bign1667 My RX-8 is lower maintenance than my Audi stick to talking about things you know about 👍
Back in the 1970s lubrication technology was the demise of our rotary engines longavity in my opinion..My RX3 burnt out the Apex seals countless times at around 50 thousand kms average..The oil i was using clearly wasnt doing its job..So a gokart racing mate of mine back then told me to run my rotary on a 50:1 premix fuel using castor oil..That new rebuild amazingly lasted 80 thousand kms till I sold the car..Its unreal what a good quality lubricant can do for an engines life.
The 12A engines also had another serious weakness. Water would leak into the combustion chambers, possibly because of heat perishing the rubber type seals - the equivalent of a blown cylinder head gasket. At 0:26 you can see those tiny grooves on the rotor housings where the rubber seals would go. Usually, the engine would get seriously overheated leading to warped rotor housings which would have to be machined, or thrown away if too badly warped. This exciting development would happen as early as 50000km!
Had not heard about the liquid piston X-engine before! That's a really unique take on a rotary engine.
The thing is conventional piston engine is at it's end of development, not further distance left for it, yet the rotary engine has not been explored well, there's a lot of future for it.
Love rotary engines, drove a few.
@@KenanTurkiye Yeah, very true - there really isn't much room left to improve on piston engines. I've never gotten to drive a rotary engine yet - only seen/heard them running.
Yeah the inside out rotary, the liquid rotor is the traditional rotor housing shape inverted, and the liquid rotor housing is the traditional rotor shape inverted, it actually looks pretty good.
@@KenanTurkiye
The rotary engine has not been explored well for a reason! If you understand German, check out Prof. Fritz Indra's, a former Opel chief engineer for engines, video on the Alte Schule RUclips channel, where he explains the reasons why those and many other engine types failed to catch on.
@@X8X8X8X8X8X8X8X8X8X Icht nicht keine sprechen deutch.
EV and Rotary engine... marriage made in heaven. Motion of parts is rotary, like the input on generator. They could put generator inside the engine. Very smooth operation. Maybe they have a better seal, and maybe it is more fuel efficient.
The liquid piston looks like the future of rotary engines
I hope that it works as it is designed to as I am not a fan of battery powered vehicles, period.
@@frederickmoller
Yeah I always have to make sure I have three fire extinguishers ready..
Don’t get your hopes up.
They need to make it open source to beat the rest; lots of comfort zone issues to be overcome. They have a serious edge over the rest, but let them not lounge.
@@Bassotronics fire extinguisher won't touch a short circuited battery.. I agree though I would rather use hydrogen. Turns ocean water into hydrogen gas.
Liquid piston engine sounds like the perfect solution as a range extender in EV's. Either only to produce electricity, or in addition help drive the car at speed, either through a torque converter or a e-cvt. Hybrid solutions would be smarter since each car only would need half the battery, or even less. It's probably cheaper and easier to produce hybrids compared to pure ev's with huge batteries.
Could even be used as a hybrid solution for mopeds/motorbikes due to the light weight!?
EVs don’t need range extenders. They already have 300+ mile range which is waaaay more than average person needs. On riad trips, they can supercharge in just 20 minutes.
@@electrictroy2010 do note that EVs absolutely require infrastructure. Take it anywhere outside the city or in a less developed country and you're constrained to only main roads, essentially. I do not know how the situation is in America, but I find the idea of hybrids quite appealing as they offer best of both worlds, being capable of zero emission driving while in the city while also maintaining the range benefits of an ICE.
@@gamespender8605 These would need infrastructure as well. Unless they're doing on board electrolysis and getting hydrogen from water (which wouldn't be very efficient), you'd need to have hydrogen filling stations.
I bought a 93 RX-7 in 95. On my first road trip I was scared when I heard an aircraft type warning buzzer and an oil light was flashing. I quickly learned how much oil rotary engines consume. Still loved it though
93 great year.
Friend had one in college. What an amazing car that I had some near-death experiences in 🤣
Haha yes. I was working all night in a 76 station in my college years. I had a RX-2. One night a woman pulled in driving a small Mazda rotary engine pickup at about 2AM looking white in the face. She got out and said "My oil light came on as a came over the hill.
I asked if she knew that the engine is designed to use oil. There was none on the dipstick. Added 3 quarts and she was back on the road.
Never was a car guy...then in my early twenties I bought a 91 RX7 .
A car with no pistons, I was amazed! I never loved a car like that, not many mechanics would work on it, so I bought a Haynes and learned to do my own repairs. Love the Rotary
Awesome for a light responsive motorcycle. The 70 hp liquid piston engine would rock
Put it in the motorcycle, it would Scream as hell
Mount one on each wheel.
I want it for an ultralight aircraft.
About 200hp in a jet ski... bring it on.
U didn't hear that the Mosby made models from 1 hp to 1000hp.... You pick your power
A 40Hp Diesel or hydrogen Liquid Piston engine would be excellent for range extending electric vehicles. If the engine goes up to 60Hp you can probably get rid of half the batteries and keep batteries and super capacitors fully charged for top speeds. Once solid state batteries come out it will be a real game changer.
I think the Quasiturbine is the best design yet.
Drove an RX7 with the Wankel, in the '80s, was as powerful as a 289 ford, very smooth.
A Ford 289 in the 80's wasn't very powerful
@@DylanL69 - Ford didn’t build the 289 in the 80’s ... The last year for the 289 was 1968, and they had excellent power by 1980’s standards ...
The RX7 was fun to drive, but more impressive was how even the 1st-gen model really woke up with the addition of a turbocharger ...
The LiquidPiston engine sounds like the HUGE leap in technology that we need right now.
yeah sounds too good to be true, I wonder how the they fixed the sealing problem
Scotty addressed that.
By the seals being mounted in the cylinder wall they can be simply lubricated from an oil pump verses the wankel having to inject the oil into the combustion chamber to be burned.
@@johnhogan3810 that'll produce the same result as the other rotaries because there was a design with an oil vein on a rotor back like 10 years ago that had the same problem and it didn't lubricate enough, I guess we'll have to see
@Kristofer FC I hope we will see. This could be huge. As with all new engineering, only lots of testing will tell. The ability to use hydrogen would also be a change. If I understand it with no gas to breakdown the oil film that would be a big change.
I don't really know much about roteries or hydrogen. It is fun to speculate and hope.
@@kristoferfc6525 this technology will never go public . Oil is too big and the green agenda has too much steam
Still running my 04 rx8 to this date. Although it's still under 90k miles. Just putt around on the weekend. He's right. It's a f'in cult following for rotaries.
I hope Mazda has success with this new engine, I’m up for anything to keep the combustion engine alive.
Combustion engines aren’t going anywhere for a long time unless government plans to have power shortage every 30 minutes.
@@starscream007 Rising gas prices ain't helping at all bro
@@justahumanwithamask4089 electricity prices are raising just as fast
@@starscream007 Exactly.
Fast chargers are charging up to 50kW, roughly 2X the demand of the average home.
Unless we develop and put solar EVERYWHERE we are in for a rude awakening.
@@starscream007 not in europe tho, more and more countries announce they'll stop allowing the manufacture of non-electric cars in 2050
Man,I just came across this channel cause I had to buy a used car in this overpriced market and was watching such videos.....now I'm hooked and have been binge watching scotty for a week straight🤣
Our stories are the same lol.
Welcome and I hope you got a good deal on the new car!
I'm literally in that boat right now...
My work car blew up last Thursday, and my truck is not feasible to drive to work in $10 a gallon gas prices. So I had to take today off to try and buy a used car for work purposes. When it rains.... *it pours, and it seems to pour a lot.*
@@risenfromyoutubesashesagai6302 better off paying gas for your truck than while you repair your old car than to go buy a new (or used) car.
Dude you have no idea how deep the Scottie rabbit hole is. I have watched him for years.
the return of the rotary engine in all its forms makes me absolutely happy❤
What I like about you Scotty... is that you keep yourself updated on the many different facets of the automobile world... and that is a truly fantastic thing because you make it very EASY for us to learn about the latest developments in this vast and complicated auto arena !!!.... I can't thank you enough, pal.... You have taught me a lot and are still teaching me....
The other thing enthusiasts love about rotary engines is due to their higher RPMs they can spool turbos that would normally be way too big for their displacement which is always fun.
Let’s get this man to 5 million. He deserves it!
Calm down snapperhead. Its inevitable
Let’s not ! He’s incorrect about so many issues. Only watched by uneducated old people
I've learned alot from scotty specially the basics love it
No
@@wileecoyote5749 Just a word of advice. You better be careful what you say to 10gallon. The last several people who made him angry were tracked down and cornholed.
Seems like a great engine for light and ultralight aviation. Weight and reliability are the driving factors.
This coupled with an EV hybrid suite would be ideal. VERY light, with the reliability of an electric motor, could give you ample time to prep for emergency landings!
I like the small liquid piston design. Hope it makes it to production cars. Be awesome if it can run on CNG or other fuels. CNG is still very cheap now.
Cng?
@@kyleoden3015 “compressed natural gas”
Are you talking about the gas Russia is controlling over all of Europe?
In Poland LPG seems to be as popular as Gasoline. On the Mazda website they kept emphasizing that rotaries are well suited to hydrogen, something they have tested.
@@MrDuncl we had an LPG conversion kit installed in our Toyota Vios. It's not uncommon here in Thailand. The problem is, LPG has a higher ignition temperature point. It burned out our engine after six or seven years of use. Loved it while it lasted.
I love that liquid piston engine, it's so perfect it's almost like a discovery and not an unvention, too bad it wasn't the main type of engine for the last 150 years instead of the typical piston engine .
well duh, it wasn't invented yet... just like how IC-engines weren't the main type of power production for the past million years... Its not like it existed but people refused to use it...
150 years ago we didn’t have ANY type of internal combustion engine. It was all external combustion (steam)
The peanut shaped rotary style engine is the future. Its scalable and has tremendous potential.
I like to think of it more like a bean
Gotta be something to that liquid piston engine... hard to say ... time will tell ... thank you mr.Kilmer.
I had an rx2 it was a hoot to drive, on take off the left front wheel would come off the ground did not matter if you forgot to shift VERY high RPMs. {12MPG}
braap braap braaaaap !! (I'm a sucker for old school bridgeports, favs rx3, rx4, rx5 and second gen rx7s)
Life time rotary engine lover, too bad people don't know very well how great an engine they are, the smoothness, the easy revs, the noise, everything, you just got to learn to live with them which isn't too hard.
@@KenanTurkiye They need replaced at around 100k? The engine seems small enough to replace relatively easily.
@@ocrapo9327 Although the rotary engines generaly do not last as long as a conventional piston variants, the various sayings 'replace at so and so km/miles'' are just wrong.
A properperly used and looked after rotary engine can last a few hundred thousand kilometres, but if you are to thrash it, meaning you rev it beyond it's supposed to, do not lubricate it as it needs, do not let it warp up and cool down as it needs it wont last much, but neither will a conventional piston engine.
The ''not lasting'' issue is even more exaggerated on the rotaries because people who usually own them envisige them to be super powerfull and fast (in original form which they are not) so they thrash them without the proper knowledge to taking care of them, so thats why the market is full of wrecked rotary engined cars, hence the common misconception.
I owned, modified and raced rotary engines, they are just like any other engine, but yes in fair comparison they are about roughly 70 percent the life expectancy, fuel economy of a comparative conventional engine.
Yet they are 700 percent more fun. : )
I had a lot of fun with my RX2. I bought it used, and unfortunately found that the seals didn't last as mentioned in the video. Oil consumption went up, and the engine would backfire when you turned it off due to the worn seals. But it was impressive to drive.
I miss driving my rx7 it smelled like I was in the gas tank 24/7 but it was such an awesome car
I've been waiting for years... I'm 79 next month and am still hoping that someone will solve the problem with this engine. It has a very high potential to be the best engine ever invented.
I loved both my RX7s. They were fun to drive.
I miss mine too
Me too:(
Lucky
they were fun. When working...
I saw the liquid piston design a year ago. I was so stuned thinking this will be the future of engines. But I guess the spotlight is on ev. Id love the idea of mazda using the liquid piston to go their path of rotarys. How amazing that would be!
great video, thank you, I really enjoy these documentary style of videos. please don't hold back on the heavier engineering components, they are very interesting.
Amazing! I knew someone who bought a new Mazda R-100 car in the '70's, which was a small car. It was fast, and would rev up quickly, but it only got 18 mpg. That is the same gas mileage that my Brother's 1958 Pontiac Chieftain 4 door sedan would get. The rotor seals had to be replaced in the Mazda after only 2,000 miles, and the synchronizers in the transmission were also worn out too. They got rid of it after about one year.
The army apparently got a bunch of generators with the small liquid piston engine and they basically can run on whatever is around
My neighbor is a military contractor and she told me she could get me these for 12k each maybe five years ago
MAZDA fan here! 1.8 GTR BPD and 2.0 FE3N for life
Mazda is well placed to engineer unique engines in a time when ICEngines are being either reinvented or replaced with electric.
So awesome to see that Scotty is a Mazda fanboy now!
He’s always knocked them. Only recently, since partnering with Toyota, has he said their quality improved.
This could make everyone happy ! That powering electric drives could be a game changer for our cold Saskatchewan winters and the limitations of battery electric performance in the chill.
You can't beat the sound of a two rotor or three rotor it's unlike anything else that's what makes them so great. But they definitely are more finicky when it comes to seals
Ever hear a 4 rotor? Was the nastiest, meanest thing I've ever heard.
wankel engines were built for german planes in ww2. not meant for cars..
2 rotors? 3 rotors!?
I think my V8 pushrod with 220k miles still sounds pretty good. Hard to beat that. But rotary engines and hydrogen potentially fixing the problems sounds good too! And the X-motor is interesting.
@@ocrapo9327 ?
Thank you Scotty, I remember as a 10 year kid I was given the Wankle Motor Model to build. It was very cool for a Product of the Mid 70's . Your visuals and explanation brought back good memories from my childhood.
There's a place for all engine types in the marketplace. There have been diesel powered, hybrid, electric, multiple types of gasoline (ICE) engines, hydrogen powered, natural gas powered, and biofuel vehicles on our roads for a long while. In the past, there were steam powered (ECE) vehicles also. The US market has always allowed for multiple technologies and that will continue for as long as people still demand them. This idea that we are going to replace one completely is absurd. The Amish still use horse and buggy. That alone shows that old technology still has a place.
One of the problems with internal combustion engines is that they use air which is about 80% nitrogen. When involved in the combustion process produces nitrogen oxides which is a pollutant.
I'm surprised that liquid piston engine isn't already being used in cars. It would seem like a massive improvement even over piston engines.
Inertia. A surprisingly powerful thing
Politics... advancing engines is politically unfeasible, with Western politicians bought by China with common people spending their money buying dollar store items.
I first heard about the LP engine around three years ago, and was shocked then to see it had already been around for some time with practically zero attention payed to it
They are comparing it to a basic 4 & 2 stroke piston engines that you find in lawn mowers and generators. Those engines are very poor in efficiency compared to the engines you find in modern cars so liquid piston engines might not be very efficient and according to their website, they might only be suitable as a range extender or in a hybrid powertrain.
When it comes to piston engines, they have valves and have a lot of displacement to mix the air/fuel mixture so they can do lots of tricks to maximise the efficiency of the combustion as well as reducing carbon monoxide, soot, NOx, and unburned fuel. So keep this in mind.
How strange. I got 23 mpg with my 1972 RX-3. Didn't come close to that mpg until I got my 2012 Honda Civic.
Was that right before the then new emission standards went into effect? My family's 73 Pontiac Ventura, with a 305 got 8 mpg!
And my 4 door Dodge Colt got 40mpg highway in the early 1990’s. It did fine, with a stick shift!
If the regulatory burden had not increased, I bet advancements to that engine & frame would be competitive to hybrids today
Scotty,
Well done! As a Professional Engineer, have been following the Liquid Piston engine, and believe it will be the future of engine power, and we will see this engine in EV's in the future.
My wife has a Mazda and it is really a mind blowing Car! I have only owned America vehicles. The Mazda is by far better than GM or Ford.
It is a ford

@@stoneylonesome4062 and then Chrysler partnered with benz
@@richsweeney1115
And Mercedes dealers were not happy that MOPAR delivery trucks were seen in their parking lots! 😆
@@jamesvandamme7786 The best vehicle right now. The same as my wife has.
I love the new drive coming off the centre of the rotor. It looks like a more direct power transfer.
I remember picking pieces of these engines up off the ground whenever some goofball would dump the clutch. Kaboom!
I think EVs with onboard generators powered by small gas/diesel engines are the future. You get extended range, quick refueling, and you can plug it in at night... so you can have one car that does it all, economical green commuter and cross-country capable. The LiquidPiston engine is ideal for this, being much smaller than an equivalent HP piston engine. They also are competitive in the general aviation auxiliary power unit (APU) market, which right now uses small gas turbines that are not fuel efficient. The LiquidPiston would also be a natural fit for a CV transmission, whether hydraulic or belt-driven. Disclaimer: I found out about these several years ago and invested in them during their initial grassroots cycle on WeFunder in 2019.
Whoever made that new rotary engine was a genius. 💯
Probably still alive

Thank you! Now I finally know what became of that old spiral bound notebook that mysteriously disappeared from my high school locker 25 years ago...
I've been watching the LiquidPiston engine for a while. I'm hoping that we can start seeing them scaled up and on the road soon.
Awesome video now i want to see them make that same engine but triple the size with a big turbo on it and let's make power the main course again 💪🏽
I literally hit the thumbs up button immediately when the video starts. Thats how much I respect and value Scotty Kilmer.
Wow! I did not know rotary engine existed. Amazing stuff.
You didn't know about this??
WOW!!! This new rotary engine sure looks promising for the smaller engines, especially for the purposes you pointed out. Regardless of of the limitations in comparison to the piston engine, it still looks like an “engineering marvel” of today!!!
Why don't they try to see if they can reengineer the 2 stroke engine for low emissions. Lots of power from small engines too.
you got a cat on a petrol engine, now you want an oil burner.?. go buy a 2 stroke diesel, see how long it is before your in jail..
A turbo-charger is the best solution for rotary power and efficiency. The strong exhaust pulses captured by the turbo make up for the weaknesses you talked about. Also. most owners opt for 2 stroke oil so it burners much cleaner.
Now this is the type and style of videos Scotty needs to make regularly. 👍
Love the Liquid Piston design and I have been watching their progress the last few years. I seems to me theirs is well suited for series hybrid vehicles. A small, lightweight engine sized to drive a variable speed generator that then powers the electric wheel motors or charges the HEV battery....max use of its high rpm characteristics.
the apex seals were the weak link in that engine!!!!! average life is 50k miles, also these engines were "BASTARDS" to get started in cold weather!!!!!!
That liquid piston engine sounds amazing, imagine it with a hybrid setup
As a hybrid or just as a backup hydrogen powered generator. Hydrogen will be the fuel of the future, renewable electrical energy systems will produce it, and transportation of Hydrogen is even less cost than natural gas. Future will be interesting and tech will be amazing...AND, no green new deal government intervention is needed, just time....

@@DrTheRich I mean car accident would be Hollywood like
@@castor2000 Not really, since there won't be a fireball. Just a loud bang, one second the car is there, one second it's only dust and debris.
I would like to see them do side by side racing and oval track racing for endurance with different size and mods to economy and clean emission standards for long periods of time to see which can best be used on the road drive times!!
love how Mazda has never given up or at least R&D on rotary engines...
I think hydrogen, I automatically think explosion....like the Hindenberg. Still, I like the idea of using these newer devices in smaller equipment like drones, weed wackers etc. It gives ample time to see things in action, make adjustments then move them to moving vehicles. It could be a really good process to moving into other energies.
They won't explode though, the fuel cell tanks are bullet proof.

Petroleum/diesel engines already internally combust
A long time ago when I had a 750 Triumph, I saw a guy who somehow fit a Corvair engine into a Harley frame and the weight and torque was so severe, he was lucky he didn't kill himself when he wrecked the bike. But it was really a cool sight to see. Anyway, imagine a small 40HP liquid piston on a titanium frame that can easily do 90 mph, and relies on solidly-built wheels with their gyroscopic stability for a low center-of-gravity solution, and a really fun commute.
This is a great video that is very informative. I like how he mentioned this engine type could be used for mopeds and other such two wheel vehicles.
My dad had an RX-7 I think it was an 87. He loved that car. I recently had to give up my 3. Mazda builds great cars.
Correct
.we had cx 9,7,5,3 all fun to drive fast,great MPG...now have 2021 CX 5-red..and CX 3 - black..customer 4 life!
@@zackkurman5107 How does the CX 5 compare to the 3 in gas mileage? Do you loose much with the bigger vehicle?
Big rotorary following and skills in NZ.
When you hear a 3.5k HP rotor rev, it is really like nothing on earth.
Liquid piston range extender for cars is what we need
The rotary engine was a great engine for opening up down the highway. Not great for mountain climbing unless you had a stick . I don't get why the rotary was not used in small airplanes. Would have been great for that .
Amen!!!
Turbocharged wankels were used in homebuilt airplanes
Liquid piston is the way to go. I have seen several demonstration of them and it seams that they will have a great future, especially in a HYBRID car
I want a Moped with that engie!
The liquid piston engine is the thinking man’s wankel, I love it 😎
The liquidPiston engine has a lot of potential but it won't go anywhere as long as a single company holds the patent. And hydrogen engines are always going to be held back by the fact that it takes so much energy to produce the hydrogen in the first place.
the liquid piston engine can be powered on diesel, gas, and hydrogen with few tweaks to the mixes. Although this engine idea won't be on the market for many years, as the Air Force, and Army have private contracts with the company.
Rob Dahm is probably watching this
Breaking water into hydrogen (and oxygen) isn't such a big deal. The most pitiful weed growing in a crack of an asphalt road can do it just fine, using the meager amount of sunlight it catches. Human technology can do it better and better in the future if there's enough demand for it. But the free market is kind of like evolution: the best solution doesn't nearly always win. The winner merely needs to be good enough but more importantly market itself better than the alternatives, or have random luck with external circumstances nobody could have foreseen. Current electric cars, hauling around those ridiculously inefficient, slow to recharge, delicate yet heavy batteries, are a good example of it.
Scotty, your videos are always a pleasure to watch. As someone with years in the game, I still learn something every time.
Without a doubt, H2 engines are far more reliable and suitable over the fully electric cars 🚗
They're really not.
Yeah i mean, highly volatile and extremely difficult to store gases with an extremely energy intensive production process is the answer to all our problems.
Way too dangerous... H2 cars are the most dangerous car every made
@@grodiosp8916 safer than gasoline or batteries, no spontaneous combustion for weeks on end because shorting the batteries at high temps, and it can evaporate so fast it cannot combust after a crash, as seen in a clip where Toyota fires a bullet at one of the hydrogen tanks
Hydrogen is dead. EVs are the only way forward, as every major car manufacturer has understood. That is also what the science says.
the question is: bridge port it out of the factory or wait until they sell it when the first rebuild is waiting for you
There is most certainly a future for the Wankle Engine as a Hydrogen engine, and there is most certainly hope for the X engine. I can't wait to see if these two engines become mainstream
Wankel, not wankle its a pet peeve cause it’s my last name
@@robbyturbo109 Robby, your last name is Turbo. My last name is unrelated to the Turbocharger manufacturer though, but I do drive a Wankel RX-8
All the same problems exist burning H2 as petro. The engine would still require oil-injection to lubricate seals, there would still be high wear, and wide thermal variance on large flat parts. H2 has no advantage over dino-fuel for a dorito-motor.
@@Doonit_hard_way_since_65 yes it does no co2 emitted and renewable only nox emissions are emitted and as scotty said if you inject water you can reduce that
Hi@@Doonit_hard_way_since_65 -
There is huge benefit for these types of combustion engines: multiple types of liquid fuel sources, less strip mining to acquire lithium, no dependencies on foreign suppliers, no requirement for slaves to create batteries & parts in China, pipelines of fuel sources to homes already exist: H2O (just need larger portable generators, like people have small portable oxygen generators.)
With today’s ability to passively extract liquid fuel from CO2 in the air, I would expect these engines to work just fine with them. Democratization of energy is upon us, and it does not mean we have to rely on slaves from North Western China to make it cheap for us.
One of the problems with Hydrogen is tank weight, but If the engines can scale they may have use running generators for Grid Storage for power when the sun/wind isn't available.
I hope that one day, we can go back to a simpler life with simpler things. I'm so sick of this fallen world as it is today. Most people have no clue the evil being done right under their noses.
OMG that Liquid piston seems like a breakthrough. I need to look into that.
I just love the fact that all these companies are switching to EVs when they have no idea what to do with all the batteries when it comes down to it we're just going to contaminate the Earth worse and then we would with our internal combustion engines
repurpose the battery or recycle it, just because it lose capacity doesn't mean it drop dead on the spot...
@@jamesvandamme7786 Battery prices are going up, not down.
sad thjhat this has any upvotes... contaminate worse... probably the dumbest thing anyone has said this year
@@fetB It's true. Batteries are anything except gentle for the enviroment. They are heavy, rely too much on random components found in underdeveloped countries and gradually lose their capacity. Cell phones are a glaring example. You would consider the smart phone to have been at the peak of development bliss, with corporations dumping money into getting an edge and doing so for a decade and a half of regular market use. And the result is batteries that gradually lose charge to a noticable level after 3 months of ownership.
@@matthewmosier8439 Opposed to literally blasting fossiles into dust, batteries (which mind you can easily, and have been keeping charge for well over a year for me, and many other people, before a noticeable drop off) somehow are worse despite modern ones literally being viable for many years? And this isnt even talking about the overall efficiency and the bottom line, which is ~25% on modern ICE and so much worse on older, opposed to ~75% for batteries. Or the environmental, animal and humanitarian impact oil had in the least few decades, somehow, mining cobalt etc., is the not so gentle comparative? It's not even exclusively true for a while now as there have been great efforts to source ethically by some manufacturers. Not to mention that a lot of batteries already are and will be built with "regular" materials. Your state of information is like 10 years old, dude, and on top of that, you lack fundamental understanding of how batteries work or you would understand why small phone batteries are more sensitive that larger ones. So no, it's not true. Like at all.
Everybody watch warped perceptions vid on the liquid piston one to see it in action. It’s incredible.
Love the concept of the liquid rotor engine. Introducing hydrogen into the fuel system would solve a ton of emission problems. See Roy McAlister on running on hydrogen on YT. Resizing this to work with cars and trucks would be mind blowing.
It would push emissions to wherever they occur in generating electricity to make the hydrogen, transport it, and store it.
@@davefink2326 well if it can be more efficient than gasoline, then it is a better solution...
@@alphaxfang nothing points to that except nuclear. Hydrogen is a container for (some of) the energy expended in its own production. Fossil fuels are containers for solar energy that struck the earth in millennia past. It takes very little energy to make gasoline or diesel from them, but plenty to make hydrogen.
@@davefink2326 at least hydrogen doesn't throw out carbon dioxide to the air... isn't that the worst part of gasoline?
@@alphaxfang I remember a device that took mankind to the moon , life support , HVAC , communications

Yeah !! Whatever happened to the fuel cell ??
Longevity was the problem with the RX8 wenkle engine. A rebuild was required at 70k miles as the seals needed replacing which cost an absolute fortune. In UK now one can pick up an RX8 on the used market for virtually nothing.
Hello Scotty! Love Mazdas!
I've owned 10 rotary Mazdas and all of them lasted over 250,000 miles with very little maintenance. There are a few rules to follow but beyond that, they were amazing cars and engines.
How often did you switch apex seals on the 13b engines?
It such a shame that these motors are plagued by apex seal problems. It would be the most perfect combustion engine ever made. hopefully it can finally be worked out. And hydrogen will be the fuel of the future, not electric slow Joe.
I wonder if the apex seals were made of kevlar, or titanium, they'd hold up ...idk if kevlar would work in the motor though. Lol
@@richsweeney1115 Stock seals were cast iron. Aluminum filled carbon for higher rpm applications, then in competition applications Mazda used ceramic seals.
@@JasonLuther1 I've mostly worked on regular piston motors, my landlord has an 04 rx8 that I've started working on, it sat for two years , I got it running, it has a code for throttle position sensor, and it burns oil ,and stalls when it's warm and it's hard to restart..it almost catches, but takes a while . I'm pretty sure it needs a rebuild. It has 170k on the body, idk about the motor..it's hard to imagine that motor ran 170k miles lol
As long as the RX7-8 replacement screams above 10000 rpm , I love it
The fact that Citroën gave up on the Wankel rotary engine is evident that it’s not really worth adopting. If there ever was an automotive company known for ripping up the rule book and doing things that other manufacturers never did, it was Citroën, and even they gave up. Just goes to show that good ideas don’t necessarily work, and even if they do work, they don’t always work well.
Over time we made improvements of what the past considered a failure. Citroën does not even make long lasting cars in the first place. They're built as fun cars and that's what they're focused on. Besides this is no longer a wankle engine that uses a triangular piston engine and also the purpose of this engine is not to be the main engine, it's design design to be as an assistance for the main.
This would last a long time if it was ran at high rpms while charging or assisting the electric motor.. wankels can last a very long time if you rev them and keep the carbon cleared out...
You do realize that Citroën is French, right?
The French are best known for their ability to rapidly retreat. They build the only cars on the planet that are able to go faster in reverse than in the forward gears ...
@@sking2173 Haha. In all seriousness though, you gotta look at it from the French perspective. They fought both World Wars in their own fields/streets/countryside. America hasn’t had major combat on American soil since the Civil War/Mexican War (and yes I know about Pearl Harbor and the Aleutians). America has a big advantage of an ocean separating it from its main enemies in recent history.
Seems like a liquid piston engine driving a generator would make an excellent stop gap for electric car problems.
Liquid Piston has done a lightweight generator {yes: disclosure; invested into - minor, last year) Compared to a 4 cycle engine the single X rotor is equivalent to a 6 cylinder standard piston engine.. but not so expandable beyond that and when scaled up, it will have to have a cooling water jacket. I still like the Wankel for it's one side exhaust and believe that the Apex seal problem was not addressed properly in the past with internal piston oil channeling.
A hybrid makes sense💯the electric will provide the torque!! I drove a Lincoln 2.0 hybrid and was getting great mileage and it had decent take-off with the electric motor.
Scotty is right.. Great design. But I hope they improve the dependable. Technology is there just use it!!!. Hydrogen I always said is the fuel of future for right now Today. Until better come out. Yes there is great other types of fuel but them types need more testing. I even got money on Hydrogen for right now. But others same as Rotary engine they need dependable & safety. Rotary is so very close. It's possible if they will work on it more. Too good of a design not to be acceptable. I highly suspect Big Oil do not want this type of engine to come on the market yet. Big Oil don't want to be The buggy whip of 2000+. It would put Big Oil out of business. I don't agree every thing Scotty says. But I do completely agree with him on this. Hopefully I get a "like" from Scotty on this post. This world deserves better. Where is all this cheap electric power going come from? Wind mills not stable. Other electric power? Not!!! Where? Why was they ever many water dams built with taxpayers money not hydro power electric Dams when it was built? It's Citizens tax money!! Taxpayers should benefit from there money too.. Just maybe it's time to get younger better Politicians & not my last count over 137+ Politicians serving right now over age of 67. And some in there upper 80's . They sadly are so out of touch with Citizens needs they still think we do need Buggy Whips as they did when they was young? Turtle Man? Charlie Manson? Miss Scooby-Doo looking for money? Huge # of these Politicians are way over retirement age. These people that really needs voted out. Time to move on from The Taxpayers Most highest paid, Best benefits Retirement Home with the Patients running it!!! Giving themselves pay raises ever year. I love be making $174,000+ a year. Who you? Scotty got great idea if political power don't kill it for campaign contributions. Sorry but they are the ones turning it into a Political problem not the majority citizens & the voters...
Liquid Power is new to me. Amazingly ingenious. And cheap hydrogen is just around the corner owing to new production processes. What I have not seen would be the climate effects of water vapor coming out of billions of vehicles. Perhaps this would cool the the climate and solve some of the drought issues. Probably that calculation has been done by someone already. It would be interesting to know. Imagine if driving such a vehicle contributed to a healthy climate. We really need competition on clean vehicles rather than a last gasp of internal combustion engines competing against electric vehicles in quarter mile drag races. Worse still are the drag races everywhere on our streets. Maybe technology can still save the day.
This mans voice gives me hope of not giving up on being a professional voice actor and narrator, but he's very informative not considering the funny voice
It is delightful to see that they are trying to keep the rotary alive
This looks to me like it has huge potential for small aircraft. Very exciting!
Scotty is close to 5 million & I say “share & let’s get him to the 5 million mark”
What a piece of engineering .
Designed by a German named Dr. Felix Wankel. The engine used a roter instead of a piston. NSU, and Mazda were the users. AMC was going to use it for the Pacer, Citroën on the G series, General Motors on the Chevrolet Vega. The latter projects were scrapped do to the energy crisis of 1963
I bought a brand new Mazda RX 7 with the original formula white paint job in 1982 with a Wankel Rotary engine, five speed on the floor, four barrel carburetor, that car screwed for 100 hp, Paid $11,500 for it brand new, right in the owners manual it said it burns a tablespoon full oil with every fill up.
