How do your arrange your coils? Are those neodymium magnets? What a cool design idea for both the alternator as well as the water pump. Very impressed.
I like his dedication to their projects, I checked in your comments that you felt that your alternator is not producing a lot of electricity. A question? These coils were your alternator wraps in a clockwise and the other in counter-clockwise? And as the coils were connected? For the video could not fix it. Another thing I noticed was the lack of magnetic flux in the core of each coil. I am willing to help you improve the efficiency of your generator.
Congratulations on your engine. I can see that the power generated is quite good and has a significant torque. However, I have a curiosity about the cooling system of this engine( i have also have seen it in other similar engines-approtechie), which is on the water pump. Can you explain me how this water pump works? I find it very interesting, but I do not understand the mechanism implied between the engine and pump operation. Thank you and congratulations again. Keep good work and new videos!!!
@olemac20 Thanks, the pump is just a one way valve, when it gets pushed into the water, the water is able to flow past the one way valve, as soon as it's being pulled out the water the water can't come out of the tube because of the one way valve. So it flows in little drips with every push.
Hey, not bad! Especially considering the amount of power used by the pump, your generator is putting out a decent amount of power. You might try a smaller pump valve and tubing to reduce the power loss there. Have you tried it without the inertia pump, maybe with an electric pump, to see how much power you can get off the generator alone?
@approtechie It did go much faster with the electric pump, I had it running around 1300 RPM, but I think that's maybe what damaged the bushing/rod combo. I'm taking apart soon to beef up the rod and bushing, so we'll see and the next run what it can do properly, What size rod and bushing do you use on your most recent engine ? I used 1/16 rod in this but it seems too weak to take the high RPMs.
@approtechie Also, I'm going to switch the tube out to the pump for some silicone tubing which is smaller and very flexible, it should reduce the energy used by the pump a little.
@specallez I think that will help a lot. BTW, I put a larger inertia pump on mine just to see what it would do and it was pumping 3 liters/minute at low head!
man the alternator looks pretty efficent. did you wind the coil yourself?

Nice stirling engine!
What is the diaphragm made of?
And how did you make the sealing for the displacer rod?

Congratulatios. Your engine gives us or me to mmanufacture an longer life engine. Thank you very much.

Would a rocket stove make a good heat source for a Stirling engine?

@specallez I've gone to 3/32" rod and bushing now and it's a lot better.

@RayzorHD Thanks, It's for cooling, the thing going up and down pumps the water around the engine.
