I love these videos! If it was 3 hours long I would still watch it.
I love these videos! If they were 4 hours long I would still watch them. Very intriguing and overall very interesting.
Stolen comment dummy
Amazing another incredible video, I really like your video, we usually think there is no margin for improvements, but there is...incredible!!! amazing one more time
Thanks, it's great to hear positive feedback and I will make more videos like this!
Superb, looks like the Future is closer then we thoughts!
You are best bro
Keeping growing tech family
So cool. Weird engine designs.
Wow, I thought the Sabre was just something dreamed up for KSP. Its abilities are even more impressive in real life.
Nr.2 ist hoch interessant, die Rest Energy wird richtig gut genutzt
The Massive Yet Tiny MYT engine has been my favorite for at least 14 years. Like what 6000 HP in a small car engine size? I bet someone has it in good use 😉
Good rare information, thanks.
Thanks for watching!
Thanks for bringing these concepts to us you seems to have a keen interest in engines. Every engine's primary motive is to generate circular motion the best efficient possible way, you didn't gave heart on comments for past many day's, why?.
Anything machine or construction related is interesting(I have an eng tech also). Sry I forget to look at comments after a a few days but I appreciate you returning to my videos and I will try to give more heart things!
I liked the rotating cylinder engine for a number of reasons. Firstly the simplicity of design then the lack of friction with roller bearings instead of expensive sliding bearings on the crankcase. Should be inexpensive to build and maintain, making it suitable for emerging countries. Very exciting.
I agree, it solves a number of quirky issues with other rotary piston engines, simplifies the crank and main bearings hugely.
I feel like the rpms would be limited with it. I wonder if there's a working model.
@@Frejborgover the last 150 years there have been hundreds of thousands of rotary cylinders of one form or another... some made it into production... some did not. none have really been successful.
I also like that the camshaft and the belt to drive it are eliminated. Also, no crankshaft and connecting rods, which are extra mass to move and balance, etc. But... it appears to use side "valves" that operate when the piston exposes them. That's been the hangup of numerous engines. There'll likely be leakage of exhaust into the "crankcase". But from the one animation it's hard to tell. I hope this works, an engine with a minimum number of parts will be an excellent range extender for EVs. It can be optimized to run at one rpm setting.
Number 2 looks really great
I can’t get enough of these videos!
Thanks, I will try to make longer videos in the future, maybe a documentary if I get time. I appreciate you watching my videos!
The Sabre engine is an astounding leap forward that I never would have credited as possible. A temp drop of 1000* Kelvin in 1/20th of a second and Mach 25 on top of that makes the capacities of a Scramjet seem inadequate to power a roller skate by comparison.
Really interesting ideas. Here is another interesting one....AQUARIUS ENGINES. They have a pretty unique combustion cycle in my opinion.
I loved the last two
I see a future in engine number 2, finally an engine that uses all the power he creates.
That means no spelling of fuel.
Ever hear of a "five stroke engine" before? If I remember correctly, it was set up like a normal four stroke engine with an extra set of pistons that would "precompress" the air/fuel mix, then send it to the standard cylinders to be ignited.....or something like that.
Hallo Cliff yes the star engine is a four stroke engine and have a smal combustion chamber with a slow Piston speed and the outside pistons are using only the rest expansion big and fast without dead channnels and valves
so when the normal four stroker turns 180° than the outside pistons have done hear work to in this 180° near it
What happened to the pancake motor? Two wavy discs rotating next to each other with the wavy parts providing compression
Number 2 is just amazing - i know the Inventor buy myself - very cool guy! Please tell the whole world about the "Deckers Cycle" so the inventor gets the honor he deserves for the years of work!!
It's one of the best undiscovered engines out there imo
@@Tech_Planet exactly!! And Mr. Deckers did evetything alone by hisself - even the Patent was written by him - i know him many years now and he always worked on his Own "deckers cycle" which just make more sense than any 4 or 2 cycle Otto engine - more energy is converted to movement than in any other way i know.
@@rootdude5163i havent seen one running...
theory is great. practice is better.
I really like number 4, the rotating cylinder engine, the are very few moving parts especially if its a 2 stroke design. however, could there be a loss in efficiency due to the centrifugal force acting on the cylinders pushing against the wall. The compression and exhaust strokes mean the piston is moving inward but there is a strong centrifugal force acting outward, could be a loss in efficiency, I don't know. still a very cool design and would be cool to see a real working model of it.
I can't stand it when people improperly emphasize syllables.
The liquid engine. Hmmm. I was thinking a spiral magnetic structure, pushing a ferrous fluid like an archemedes drill would be fun.
That Sabre engine has been knocking about 20-30 years? Always hear it's almost ready. Kind of reminds of the continuous reach for fusion power. So far with the same results.
I understand, hopefully it turns out to be renowned engine because we definitely need more diversified ways to access space.
Sealing and centrifugal force are the main bugbears of most of these designs - there is a speed at which rubbing surfaces start to suffer exponentially - things start to get critical; passed 25m/s - your engine 4 with its large-diameter track would hit that at fairly low revs
Out of all the space engines i am still big fan of Aerospike in some of its iterations.
And quite annoyed at the complications with plain rotary / wankel engine, so many complicating factors for something with such a potential sadden me greatly.
Yes both preferred types are bit unusable in most iterations available today and come with just whole slew of problems that make them less than ideal. Tho good aspirational things to work on as engineer i reckon.
Nr 2 needed the double ciykle parallel that's new
Rotating cylinder: this is the Rotorfugal that I heard and read about in 1975-76. I made a lecture on it for English and got a 10 and admiration from teacher and classmates. Nothing new.
Man. You love the Sabre, don't ya?
I love SABRE & have been following REACTION ENGINES & SKYLON
2:05 Super lol
The double cycle really is parallel
AWFULLY BIG PACKAGE FOR THE DISPLACEMENT!
A steam engine was designed in the late 1800s that is very similar to the #4 engine. It's basically identical. Kinda cool.
The Number 2 is not a steam engine its a ic engine with a direkt double cycle but it can used a steam effekt because the expansion is big enough.
7. it seems it would produce little torque and not sure how would you combine more than one... um cylinder?
6. what does hold pistons? i guess sealing those pistons would be hard.
4. i dont think you can put 2 cylinders in a row here.. also low torque? also it may be pretty big with lots of dead space
3. seems that rotating valve is only useful for max of i4. i5 would need tube with 5 compartments and than valve coverage would get small. v6 or v8 would also be possible. either way there are rotating valves that can do much better job with exchange of gases in cylinder. not sure if this is easier to seal or anything.
2. no idea how you service that engine... also seems that rotating mass is pretty big
Could you take a standard fuel injected engine and put it inside a vacuum so that there is no resistance on the pistons...instead of using grease you could use magnets... That keeps the piston in position and the vacuum allows it to move up and down very fast
A combustion engine would not work that way. It is a good idea but creating a vacuum for the cylinders to move in would be very difficult and hard to maintain. Using magnets to eliminate friction is qlso a great idea but there would be a gap between them that would allow air through. So you could not combine the 2 concepts.
I think that magnetism and using magnets for energy production has been overlooked for a very long time. I believe they are a ket to future energy production.
Ramjets are pretty awesome .
That rotating cylinder engine would probably have bad power to weigh ratio
Check out Erickson Motors FE120 & FE200 full expansion engines.
Most of these engines have an unfavourable ratio between functional volume and total volume.
I designed a new version of the concept of the MYT (10 times lighter) is on its way that will take the market very soon. I cannot share it for now but it is much better since so much power is available, it needed some very important modifications to make it even more powerfull and resistant.
do you have a website ?
@@ralfdeckers1703 i have a problem with the provider, it will be available shortly
This video chanel maby can change the world technology
You have an impressive design, I would like to see it running one day!
It's all fun and games until some poor bastard has to repair it.
I want to see one with two or three moving parts and no timing needed.
Moving Parts are not a big Problem . The thermodynamik brings the big losses The Losses from friktion and so moving parts are in a normal 4 stroke engine only 7% forget the problems with moving parts.
Most incredible engines that you know about... Not that exist..
Wait and see. All Projekts in the world are starting with a idear. ore you do nothing
Great video, I love your content! A few notes though:
1) #5 is not actually self fueled, they need to feed the gallium alloy droplet with some aluminum flakes to get it to start the reaction which drives its motion. Its discussed here: th-cam.com/video/ErCOTdIruoc/w-d-xo.html
2) The Mach number which the Sabre can achieve (or any aerospace vehicle for that matter) is a bit of a confusing metric as the speed of sound not only changes with altitude, but it does so non-linearly. For example, Lets say we have 3 aircraft A B and C all moving at Mach 1. A is flying just above sea level, B is flying just at the start of the stratosphere, and C is right at the top of the stratosphere. As you would expect, A is traveling faster than B and C. However, counter intuitively, B is actually the slowest of the three, with C traveling faster despite being at a higher altitude. As well, from an engineering perspective, something may be able to achieve a high mach number at altitude but be incapable of doing so near sea level. Without a doubt, the Sabre could not achieve Mach 25 near sea level as the aerodynamic loads and aerodynamic heating would destroy any aircraft traveling that fast through such dense air. However, up near the start of the mesosphere that likely won't be a problem since the air density is low, despite the speed of sound there being not much different from sea level. But above that point the speed of sound becomes sort of irrelevant because the air pressure is so low that you would need to start using some rather expensive pressure transducers used for deep vacuum chambers just to read the air pressure. Classical pressure based altimeters would have stopped showing you an accurate reading long before then.
Sabre is best one👍

The moment he said the Sabre Engine was "rapidly progressing" I switched off.
I'm an aerospace engineer who has done supersonic engine research and for anyone to say the Sabre is "rapidly progressing" is full of shite. This thing has been under "rapid development" for decades. Like many other engine concepts its got some concept that's based on a reasonable principle but in reality its mainly garbage.
The reason why the Wankel Rotary almost threatened the reciprocating piston engine was because it could be practically manufactured and be practically used. This is one of the things so many inventors and their proponents NEVER UNDERSTAND. Unless you can use it in a practical way and that it has advantages over existing technology it doesn't get adopted. The world of engineering is littered with 1000s and 1000s of "the next great thing."
If you have ever worked with any of these innovative people *AND I HAVE* they don't listen to anyone. In their brain they are smarter than everyone else because they thought up "blah blah blah" and therefore don't need to listen. I have watched people blow billion dollar opportunities because they wouldn't listen.
I just love it when people who have no engineering education tout " efficiency" and "advanced" when describing different engine architectures. The very first first one you stated as the "most advanced: has been around for a decade and dismissed by engineers across the spectrum as the most problematic and inefficient. I lay terms,....
Give me a break!
I think sometimes you have right, but not every day
wait you mean RAPIER ENGINE FROM KSP WAS BASED ON A REAL ENGINE😱😱😱😱
AND THE LEGENDS ARE T R U E ?!?!?!
Too bad the MYT Engine was a scam, good luck to the rest of the designers.
Looking for qualified investors: Remember Cyclone Power? I'm looking for someone that wants to partner with a project where the primary goal isn't about the boat or the land speed record, or all the rest of the bullshit CYPW wasted money. The only 'sizzle' in this pitch is the ECU design that enables the engine to operate with infinitely variable valve timing, so the engine operates as a "Programmable Torque Source".
There are no snazzy color photos, there are no popular "oohs & aahs" to be had, this is pure "Engineering Porn" for those who are tantalized by results, not the star filter in the glamor shot.
There's nothing strange, other than it's a vertical shaft radial.
What can you say about this engine? Thank you.

Hallo Vlad what do you want to know about the unwasted-energy engines
@@ralfdeckers1703 Everything!
Thanks for asking. The dual cycle is new and can used by this radial engine also by a new achsial engine and also by a wankel . the dual cycle used the rest heat recovery verry direktly parallel. the efficiency under full throtlle is probably 30% higher we are on the way to build a real test version
@@ralfdeckers1703 Does dual cycle mean 2-stroke engine?
@@vladshapoval767 No the main engine is always a four stroker and the second expansion zylinder is always a two stroke engine. the second expansion is only for a big fast rest expansion. its a compound engine
I prefere a electric engine. How about we talk wich engine would be best to generate electricity.
Take a look at youtube under unwasted energy there is a wankel with a double cycle this will be good for a range extender
This dude doesn't know what he's talking about. Sabre engine and space travel... Nope. There's no air to be condensed or to use for cooling. The Sabre is a combination of a jet engine and a rocket. You see, rockets provide their own fuel and do not rely on the oxygen in the atmosphere, while any an all engines do require good ol O2 to oxidize (accelerate) the fuel being used.
The Sabre could be the new lead in LOW-EARTH orbit. But it has no application in space travel my friend.
Please do a little more research before you make our population less intelligent than it already is, thank you.
Your's sincerely, a guy that knows how to use Google.
Too many parts.
witch engine ?
none of these are really anything special. all just complicated ways of doing what all engines do anyway. convert linear to rotary. for the most part, running the "otto cycle". (beau de rochas!)
even if that dreckers engine looks like a work of art, its still nothing really... different. lots of pistons, cranks, conrods, cylinders... i see things sliding... sliding is never good.
the sabre just looks like a money making scam... "1000K temperature drop in 1/20th of a second"... for what purpose? and on what volume of gas? from what starting temperature?
how about the "humphrey pump"? it uses water as the piston, has no crank, no cam gear, though it does have valves and a self operated mechanism actuating them correctly. and is actually quite possibly the most efficient ICE ever devised, with a theoretical efficiency of 52%? of course, a major challenge is driving anything with it... though it isnt really a big deal...
sadly, it was overshadowed by the onset of WW1 and was forgotten about... one still exists, and operates, in south australia.
Poorly explained in every case, way too short and devoid of detail.
Way too much attitude in the commentary. A definite thumbs down.
They never do nothing with any of these engines so what's the point
Proof of concept. Someone some day may improve on them and make them practical.
Very poorly done. Cute, but does not give enough info to be useful
