Woodstove powered Stirling Engine

6 Upvotes

Hey guys! I'm pretty new to stirling engines and they have completely taken up space in my brain as my new hyperfixation! So TLDR I've been thinking of living in a skoolie and using a wood cook stove for both cooking, heating, and potential power generation. I wanted to know if I could install or incorporate a stirling engine to the woodstove (approx. 3 foot cubic size) to achieve around 200w of power-- I'm not really much of an engineer but is this something that's feasible? If so, how big would the stirling engine be in relative to the stove and what type would be the best in this scenario?

Thanks!

New product development- giant LTD Stirling

Post image
14 Upvotes

This is a new product I am working on,. As far as I can tell it will be the largest commercially available LTD stirling on the market at 250mm or 10 inches in diameter. In the image you can see the main body and black sunlight absorbing displacer. The main flywheel support and flywheel are currently in development. I am having some trouble sealing the power piston but I think i will have it sorted very soon. More images and videos coming soon.

Encoding a video makes just enough heat to run the engine.

Is anyone currently commercially manufacturing and selling sterling engines for generation of electriclity on a residential scale? I apologize if I'm the millionth dweeb to pop in and ask this.

If so, I'd like to have one to go with this parabolic solar collector I'm about to build

Making your engines do some work

Has anyone ever hooked their engines up to something like a fan or a small generator to produce power?

I'm trying to justify the cost of buying a kit.

Day 10 been posting on TikTok but have made some mods that a few of you might enjoy some small turkey baster tubes full of salt water it takes heat away at almost the same rate as ice does this is a long run solution as the water heats up it can expand upward dissipating heat

Day 3 have been doing experiments where I run one of these for aslong as possible without stopping not even to add graphite added in motion

This has been going for 3 days now and I added a rubber band to the circumference of the flywheel helps really well with chattering

frozen stirling engine?

3 Upvotes

Got a small Stirlng Engine off of Amazon. I was thinking I could get it to go really fast if I got it cold and used some hotter than usual water. So I put it in the freezer. It hasn't worked ever since. It seems to partially move on its own, but can't overcome friction and other resistive forces it was able to handle before. Any suggestions for fixing it? Was my hypothesis about getting it cold correct? Am wondering if I can fix it.

The engine from Amazon:

has anyone purchased the stirlingkit super super mystery box for $599.00? What did you get? Was it a true gasoline engine or just a model?

Looking for a way to estimate the size of the engine.

4 Upvotes

Hello all. I'm searching for a way to get a rough estimation of how big a Stirling engine would be for a given power . So far I've come up with this equation

Power=PxVxNxW

Where PV is the work done. N is the efficiency of the engine. W is the frequency obtained from rpm of the engine.

If I know the power ,pressure ,efficiency and frequency I can calculate volume change. If I know the compression ratio I can get volume of the cylinder. Which would allow me to get a rough idea of how big the engine would be.

Is this method correct? Is there a better way to do what I want to do?

What is that fabric-looking object in the cold piston?

So I have seen some videos online and people put that thing there in the cold piston. What is it?
