#9 Stirling 2 Component Assemblies

[cornwallav8r]

I want to build something similar...Nice implementation however I see several serious design problems at least from my view.

1) Way too much moving mass

2) Ceramic of epoxy base not tolerant of heat - will melt as likely you learned

3) Too much friction

4) Bearings needed at all joints

The cylinder Must be sealed at both ends...to create Pressure and Vacuum...

Those shoulder bolts, look more like elbow bolts to me.

Can't wait to see how this runs! Very fine work!

Do you have a link to a website that explains how to cast the ceramic pieces like that? Using ceramics to reduce conduction losses is a good idea. Thanks!

[PulseFuelNerd]

Not on GreenGasFuel as yet. I may build a heating element ceramic head in place of the copper for testing. I will YouTube the process.

1. Build a mold (one time use).

2. Mix 2 part Epoxy

3. Add ceramic mix until very thick.

4. Pour into mold and VIBRATE!

I will have to find materials links.

Hope this helps for now.

nicely made well done cant wait to see it move

Beau travail - encouragements

Nice job man. I am concerned about the fact that you are pressurizing the whole setup, gearbox and all. If so, won't you lose power? The piston power stroke gets its power from differential pressure, so you want the opposite side of the piston to be unpressurized. You will get more volume of air to work with, but not as much power as possible. Am I right? Nice job anyway though.

[PulseFuelNerd]

The system is in one atmosphere naturally, it already is pressureized- think about it! Increasing working fluid system pressure increases output, decreasing pressure lowers outputs.

I love the stirling engine

We are on the same path

Phoenix labs??

Are you in Phoenix??

Let me know if you need any help

I have a machine shop

And am working on Solar,Stirling,Gasifier,Wvo!!!­ECT...

I have a few youtube flicks saved using the rombic drive!

[FabricationStation36]

I'm not sure if it is the camera angle or what , but doesn't that piston look WAY too big to fit into the cylinder bore ? ? ? ? ? ?

[PulseFuelNerd]

Can you believe, this entire engine completely disassembles, in minutes, with only four allen wrenches!

[cavebandit]

AWESOME! Absolutely amazing construction. Can't wait to see the results. Keep up the hard work.

[PulseFuelNerd]

Thank you cavebandit, lots going on, Can't wait to show this and more.

[jousterusa]

Very, very nice work. Is there any chance we could get you to come down to the HHO Games and Exposition IV in Florida in mid-November? Inventors are provided with free booths. ExxonMobil may be showing its onboard hydrogen generator and we usually have a lot of great HHO devices for a variety of applications, and will probably emphasize coated titanium kits this time. Yours would be the first Stirling engine ever shown here.

[PulseFuelNerd]

Thanks jousterusa,

Not looking for grants, not looking for fame, but changing our world is good.

Any interest in coming to Phoenix?

[llewgnal]

Slowly but surely Nice to know were you are going before you spend the money on the ticket. Hydrogen gets the modt bang for the buck, think I heard somewere it expands quit a bit and contracts yhe fastest of all the gases ?, does the pressure increase this?  Gary

[PulseFuelNerd]

Well Said Gary,

H2 rocks! Pressurizing the working fluid and using H2 increases output. Independantly and/or collectively.  I look forward to the data steps that proves this.

[llewgnal]

Got to say this is one of if not the most well constructed and beautiful engines if ever seen...

What kind of parabolic mirror are you planing to use? I have plans for using a 60" satalite dish with the tracking motors to track the sun accross the sky so that my collector is in the optimum focal point all day long. Also shouldn't your displasor shaft be stainless for the sake of corrosion above the main piston? You are doing a killer job!!! Keep it up and you will beat those patrolium So's and so's to a fine powder!!

[PulseFuelNerd]

Thanks bluanvil1,

D3's 10' dish is mylar coated. A 2x4 catches flame in ten seconds. The two axis tracker control has been purchased.

I'm not aware of any corrosion issue of the displacer shaft.

Bring on the sun!

[marthale7]

wow.... Well thought out, hope it works for you.

[PulseFuelNerd]

Thanks for the warm wishes, PFN crossin fingers....

[ZeroFossilFuel]

FANTASTIC! You must be very excited to fire this thing up!

[PulseFuelNerd]

Thanks Z,

Yes, but the finish is overdue. However, there is still more steps to completion. Maybe this week.

[insAneTunA]

I'm excited as well. Ohw man, what a great setup. Can't wait to see it run. Good luck with the build.
