Derek Keogh: The Germans were working on something similar in the late 30s then all of a
sudden it vanished! Well done your on to a winner.
wavsunlimited: Use air tank or it is somewhat useless.
Might as well rip the motor out of the vaccum since everything after that
point is just energy loss.
Nice design. Looks classy and simple.
策刘: It is just a very normal engine for the old propeller air plane back in
history. Replacing gas with compressed air doesn't mean that you have
Steves Projects: this seems similar to a split cycle engine
well done very clever !
raw150: add a carburettor and ignition system for a good old fangled two stroke
Mathias B: Wow that's Awsome, maybe the solution to a cleaner environment :)
DoNotPushHere: The integrated piston valve can be further developed... I had a similar
design before watching this. Mine didn't work on vacuum (didn't intend to)
but the trick was to drill on the piston: a side hole, and a bottom hole,
communicating; and on the cylinder two side holes: one on apogee for
exhaust, and of course one on the lowest point of the side hole of the
piston. Thus, it works like a pop valve engine, but without any spring.
Gotta make a video of that
Anyway I love your work...it's very encouraging, since I don't have any
lathe or table drill. Just a couple of simple tools
Hans Zarkov: If you slapped a propeller on a larger version, stuck some wheels on it and
got the contraption going 20+ mph with peddle power... adding wings might
get you airborne.
matt .r: great design and great application.
Eugene Syvyk: I think it would be great if you could scale it up, and put it on a
bicycle. You would still need to pedal, but you'd have much more smooth
acceleration, and much more smooth cadence on your legs.
VideosWorthSpreading: I wonder if this would be more efficient than Angelo Dipietro's compressed
air engine design.
Vatslav Orlov: Why aren't we funding this?
ever grou: esto era lo q yo queria hacer en una ciudad hay tanta energia q se
desperdicia dia dia en llos lugares publicos en las pistas y calles
hay mucha energia q se pierdes y este es justo el modelo q yo pensaba
para generar energia
DONFREDO: Brilliant and ingenious. What does it do ?
Mitch Sandoe: Air Rectifier! Oh that's genius! Yay analogies! Is the concept of a fluid
flow rectifier much more common than I'm thinking it is? I only know of
rectifiers in an electrical context. Good on you JEPLANS! Now make a
kinematic marvel that draws pretty symmetric things!
Dmitry Demin: Интересный двигатель с пневматический/гидравлической системой
"газораспределения" - т.е. без коленчатого вала.
Lyndon Pedersen: Clever work. Well done!
Diego Martin: GREAT JOB. CONGRATULATIONS!
darryl barton: I would like to see this adapted to a vehicle drive train. Cool
el xero: very nice, but since I kno wnothing about this sort of thing what is it's
HUCHEMS119: Cool design. Look like the steam engine from Cyclone Power Technologies.
Faisal Almalki: The pedal design is genius, would be useful in my opinion to operate a
lathe, but is sure has alot of good uses!
joaquin holman: this looks so weird
uni000ver000sal: When is the large scale model coming out?
I bet you need a compressor for the larger model.
You need a combustion engine to power the compressor.
Why not use the combustion engine instead?
Windu Hernowo: Nice, will you please upload your air flow directions, so we can understand
the basic ?
Сергей Горбачев: Ну и нах! это надо?
Mick Anderson: Beautiful to watch, but what's the point ?
7NtKazze: Reminds me of Gyo
ArchangelLightTech: Marty! come over here!
mike peine: Compressed Air can power any converted fuel engine . A water/windmill can
directly power a air compressor & store the FREE ENERGY without the need
for batteries until needed . The world hasn't needed oil etc... as a fuel
Germán Sato: ja aqui uno neumático Radial Air Engine
stewiecasserole: Bullcrap you made this.....you just pulled it out of your R-Spec Honda
Karmijn Hendriks: As someone with Restless Leg Syndrome, i laughed very hard. You actually
could power the world with that :P
anttt69: lolz, you must be slightly dumb. 100% efficiency is not possible (on earth)
due to obvious reasons.
Balasubramaniam Ts: hi ,jecket maybe this air engine can be fitted in a two/three wheeler and
powered by air hydraulic foot pump (check streetstrider on youtube ,mayb
ellliptical foot can be fitted int he vehicle which power teh air hydraulic
foot pump which in turn is connected to the air engine which in turn powers
MrHuskerOne: Would your hand be considered the engine since it is producing all the
DnBastard: why don't you people mention the process involves "recruiting" hundreds of
people through youtube? Google "pyramid scheme"
Eli Witz: I watched this video while taking a dump. Um, I'll give this one a like I
bptryp: what rotary engine has pistons?
JEPLANS: Maybe, they certainly should hold up better. When kids/people see it they
want to run over and pump the bellows as hard as they can to see how fast
it will go. Without reinforcement on the folds the paper bellows bulge and
cave under the stress making them useless. I can't fault anyone for doing
this because that would be my reaction too.
JEPLANS: Sure 16 would be possible, any even number would work. Sets of 4 are best.
Check out my "Inline 4 RPM Tests” video it has the same piston dimensions
in a different layout. It’s faster because of a smaller fly wheel. I am not
sure running on a continuous basis directly from an air compressor would
have much point. But as part of a stored energy recovery system it might. I
hope to have time this summer to rig it up with a scooter and a HPA Paint
Ball tank, just for fun.
