It really is just a pain. I added 2inches of more displacer to fill the chamber all but an inch. I did this thinking that the less air the more pressure. I shortened the displacer crank slot to almost 1/2in so that the throw of the crank is almost 1in, giving the displacer 1/8-1/4 inch top and botto...

Yea, that was the first type I tried. Idk what materials the guy used but no glue sticks to balloons and his wire bends aren't descriptive enuf. I guess I really need a diagram or template because looking at what he does and trying to replicate it are two different things.

With a swift spin on the flywheel with your fingers it rotates nearly 5-6 spins. I'm going to redo the displacer with a tighter fitting one and seal the top can to the bottom can other than that.. It makes no sense to me why physics aren't working.

No your not looking at the pictures correctly. The only real difference is your sides of the top can are cut out. My stand isn't pictured. The top can just holds the crank. The top cans bottom is the bottom cans top.

Sorry if this is too many pictures. These are if the crank.

These are a few more if the make up

The displacer is now made of light weight floral block foam with cardboard cutout for a bottom. I have a few more pictures of the crank and the PVC fixture if it will help you guys figure what the problem might be. Should the displacer touch bottom of the can when the crank is at its lowest point an...

Thank all of you for all of your help! I'm sure and confident that I can make it work with your helps. I will be posting pictures to this engine in about 15-20min. Thank you!

Because the balloon is the energy transferer right? The balloon helps "push" the crank along with the flywheel. It's the only two spots recieving energy. The displacer is in a wire that falls on its own therefor cannot transfer energy upwards. Right?

I'm designing an electric generator Guys. I just need my engine to work so I can further my plans. I scraped the coke cans and the whole "middle of can diaphragm" concept for an 2 Tin can "curved PVC pipe on the side" concept. My pro Len with this engine is that without the push ...

Im not trying to be harsh but its really like there had to be a problem one place or another.. For instance, once the crank seemed ok.. The push rods were to long for the balloon. Once I shorten the push rods, the balloon wouldn't travel far enuf up. So I let some slack on the balloon, what's that d...

Ok. Well thanks everyone. I've just had my last attempt to buil one if these engines. Turns out I think it all is a sham. I realize now that the engines don't do what they do in the videos because they are just a bunch of glued together cans and wires with a balloon and some fishing string. I'm sorr...

So basically, I'm doing too much? Trying too hard? I figured the displacer would have to rise to the very top of its travel limit. Maybe that's the problem along with air leakage.

Lol, there was no motor plan. I looked at the other engines being built and started to build from scratch under my own assumptions and common knowlage of physics.

This is a beta can engine. I'm trying to decide if my crank is right. If my displacer lifts 1.5in, should the balloon also lift that much in retrospect?
