     @nugger remember, there are a ton of really interesting designs for engines that just didn't get made in the past because the tolerance requirements were too high.

     @sickburnbro EHHHHHHHHHHHH
     IM AWARE OF THEM
     THEY'RE ALL JUST FUCKIN AIR PUMPS
     LIKE THE VANE MOTOR
     THEY HAD A GOOD REASON TO NOT GET BUILT EVEN WITH MODERN TOLERANCES AND ALMOST EVERY TIME JUST BY LOOKING AT THEM MY FIRST THOUGHT WAS "OH THIS IS GONNA WEAR LIKE SHIT"
     MODERN UNOBTAINIUM MATERIALS, TREATMENTS, WHATEVER
     OH
     THIS THING NEEDS WANKEL EDGE SEALS
     AND OH
     IT'S GONNA EAT THOSE EDGE SEALS
     AND IT'S GONNA EAT THE CRANK PINS ITS GONNA EAT THE NEEDLE BEARING SLEEVES
     
     IT'S ALL STUFF THAT'S COOL FOR AN AIRCRAFT BUT NOT FOR THE CIVILIAN LAND VEHICLE INFREQUENT AND LESS THAN DILLIGENT MAINTENANCE CYCLE

     @nugger but the key again with a wankel is the same thing you have with a normal piston engine - When you have insufficient tolerances you have to bridge the gap with parts that wear.
     
     Normal piston engines had to have their top ends rebuild on the regular in the 50s. People judge a new engine design against reliability that was earned over millions of engineering hours.
     
     The key is that at some point there becomes diminishing returns on a given movement, and we are probably pretty close on a piston engine.

     @nugger @asa have you read about nautical two stroke designs

     @asa @sickburnbro TWO STROKES ARE BLOWBACK FIREARMS EQUIVALENT
     AND THE SHIT PEOPLE DO TO MAKE THEM WORK LIKE RESONANCE CHAMBER EXHAUSTS AND THE LIKE -- ARE LIKE DELAYED BLOWBACK SYSTEMS

     @sickburnbro MY PET ISSUE IS THE SPLIT SINGLE PISTON
     
     WHICH IS ACTUALLY A LOWER TECH AND LESS MAINTENANCE DESIGN
     ITS A TWO STROKE DESIGN FROM BACK WHEN PEOPLE DIDN'T GIVE A FUCK ABOUT MPG AND EMISSIONS
     IT HAD GREAT MPG AND EMISSIONS AND PEOPLE AT THE TIME LOOKED AT IT AND SAID
     "EH
     THE WEIGHT AND SIZE OF TWO PISTONS FOR THE HORSEPOWER OF ONE?"
     AND DROPPED THAT FUCKER IN THE TRASH
     
     BUT TODAY
     OH BABY

     @nugger @sickburnbro I was reading halfway through this post when I realized you were talking about engines and not guns this time

     @nugger there is also auto-ignite for gasoline engines, which would add a lot of efficiency. BMW, iirc had a working prototype before everything became "muh battery car"

     @sickburnbro ITS KINDA DIFFICULT TO SCAVENGE MORE ENERGY OUT OF COMBUSTION, PERIOD
     RN THE ONLY THING GOING FOR US IS BRAKING A TURBO WITH A GENERATOR AND FEEDING THAT ELECTRICITY INTO A HYBRID POWERTRAIN
     SO WE'RE SCAVENGING FROM EXHAUST
     AND THAT PLUS 4T ICE THAT WE'RE MAYBE RUNNING LEAN AND MAYBE RUNNING ON A MILLER CYCLE WITH VARIABLE VALVES -- CAN GET US INTO HIGH 40% RANGE OF THERMAL EFFICIENCY
