Ill just leave this right here

Round bottle, better be a radial... :Jester:
-
Soap IC engine?

I was thinking perhaps a Ray Hasbrouck twin oscillator. Perhaps scaled to have the parts fit.

I must be stupid as this is totally lost on me. All I can see is water and bubbles in bottle. :shrug: :shrug: :shrug:

Perhaps it’s generating CO2 to drive an engine without the compressor noise, or acetylene for a hit and miss.
I am with you Robert. I suspect an “in” joke, but I am on the outer?
MJM460

Nope...you saw correctly, just an new emptied and clean bottle. I was floating an idea to perhaps generate conversation about the subject line.

You did see my post directly before yours now did you?

Yes! But running! On compressed air
-
I wonder if you could do a hot air engine in a bottle?

That would be a challenge. I think the waste heat issue would make that challenging to say the least. I was thinking perhaps something more attainable like an occillator running on compressed air.

Dave,
I am building a kit engine right now with tiny slotted screws which are a pain not in a bottle, I am thinking that Allen head cap screws will be the simplest to assemble with in a bottle. What is the size of the opening?

-
Tiny havent measured it, but about 3/4 inch. 19mm or so

I remember seeing a small oscillating engine jn the science museum london that would have fit through the neck of that bottle!
Building one that is bigger inside that at least looks like it none of it would fit through the neck is the problem.
What about self assembly parts of brass plate with embedded miniature magnets ? A carefully finish pair of plates can be attached with almost no obvious joint , so a large base could be made from smaller pieces.
Similarly, just as large steam-engine flywheels are made in section a small one could be made to almost self assemble with magnetic sections.
The oscillating cylinder could pivot on magnet etc.etc.
-
It should be a Bottle Engine, to go in a bottle!

Actually have one of those...but would need a BIG bottle, and its not self starting

Yes I think just about any oscillator could do, but your right about the flywheel...and it would need to be big...MUCH bigger than the bottle neck...for the right effect.....hmmmmm

I still say find a glass blower, cut the neck off, build the engine then reattach the neck. :lolb:

Wellllll Yeah....we're just jawing about it.. but it did get me thinking.

Good enough glass weld and who's to know :shrug:

Its always fun to hear people who think that wooden ships in bottles were done by cutting and refusing the glass, till they are told the melting point of glass...

You might overcome the self-starting problem by using a ferrous slug in a brass flywheel and an external (to the bottle) rotating magnet to remotely revolve the flywheel.

Now that is a thought.....though..I like the self starting aspect...of course there needs to be a tube to the engine either for inlet compressed air, or outlet exhaust air....probably through the cork.
