I'm filming an episode for my show warped perception where I do some crazy things with
this little stirling engine right here I'll leave a link to that channel below if you're
not already subscribed I'll before I finish writing that episode I had something that
I'm really curious about and that is how long can a stirling engine like this which is considered
an external combustion engine run Non-Stop now before setting this engine up to run Non-Stop
I want to show you how this engine is normally used you have this little fuel bottle right
here that you fill with alcohol you like the wick you let it heat up that back cylinder
for a few seconds then you give the engine a little push to start it
so that's how it's
normally used how to make this engine run Non-Stop I'm going to have to take this little
alcohol bottle out and put a natural gas line in its place which is basically an unlimited
supply of fuel for this little engine this is the hot cylinder and this is the cold cylinder
and this is the heat exchanger in the middle my guess is that the hot cylinder the cold
cylinder and the heat exchanger are all going to become about the same temperature and that
is going to interrupt the stirling cycle because I know the bigger versions of the stirling
engine have like an external cooling system hooked up to the heat exchanger so that's
what I guess is going to happen but I guess we'll see
it seems like the heat exchanger
is hot this cylinder is pretty hot as well and it definitely lost some of its torque
I'll leave in a little longer and see what happens
yeah it's got a little bit less torque
the heat exchanger is pretty hot it's about 250 maybe 300 degrees that I'm sure is pretty
hot and this cylinder I don't know it's actually pretty warm but it's not too bad it's maybe
about a 120 or 130 degrees and I noticed it's making a little bit more mechanical noise
now maybe some of these joints need some oil I'm going to leave it a little bit longer
and see what happens
I'm pretty impressed this thing is running Non-Stop and it's super
hot but I really thought this was going to be more of a hot-air engine then an actual
stirling engine because this heat exchanger right here is what keeps the engine running
because of the difference in temperatures from hot to cold that was surprising it looks
like this is a pretty awesome and accurate replica of the stirling engine no doubt really
impressive if you're interested in buying this model I'll leave a link in the description
below but this is good news for me because this means that I can push this engine farther
and harder and see how much it can take and that is going to be my episode I find it really
interesting that all this engine uses is are two pistons and an external heat source to
produce power it's kind of hard to wrap your head around if you think about it but that's
what the stirling engine is so that's it for this video let me know your experiences with
the stirling engine and if you like this kind of stuff subscribe hit the Bell check that
out there's a couple options there and that's about it see you soon
