My second Stirling engine generator, produces around 50mw

video My second Stirling engine generator, produces around 50mw

This is a more reliable Stirling engine generator that I built. It has a graphite piston and a larger cooling tank, so it will run all day powering the radio. The displacer is steel wire wool. I haven't measured it properly yet, but I think that it's slightly more powerful than the first one I built. This one will just about run the radio on one candle, although it really struggles with the LED's using three candles. Photo's will be available soon on my site : http://sites.google.com/site/reukpower

this would be sweet if you had a fort in the middle of nowhere like a forest. and you had a wood stove you could power lights and a radio like here.

How practical would a wood-fire generator be? I could see that ideal situation to work flawlessly.

it would work to. like even all night if you had to

I could live that lifestyle. Pizza oven must be included though.

ya i think thats all i would be eating

would it be possible to make one from 55gal drums and 2" exhast pipe and on a smaller scale can a car piston work or does it have to be like steel wool

hey since your producing enough electricity could you put a eat plate instead of candals

so can u pls tell me how to built this step by step please.

why does it slow down, thats not right.

Question...Does it matter what brand of beer can you use? Kidding. Nice job!
Imagine how much power you could produce from a 1 gallon paint can sized Sterling engine....that would be cool to see...hint hint

Well, I'll just have to conduct a comprehensive study of all brands of beer to be sure! Heheh

I do plan on trying out a coffee pot Stirling engine sometime!

Thanks!

now if you use a voltage quadrupler circuit , that will be 75ma and 24v and , voltage goes up so the ampere a little bit as well. regulate that 24v and charge a 12v sla ...yey. Great thanks

ha ha very funny! Thanks for the laugh.

maybe next time supersize it with a campfire and some large piping or barells

Very good job.. Thanks

Very cool! For some reason, I have the Hogan's Hero's theme song running through my head now!

Are you going to post this as an Instructable? I have a machined brass piston/cylinder combo thanks to steveastrouk's CNC lathe, but only bits and pieces of scarp bar/tube to make the rest, so I was imagining making a design something like yours. I'd be interested to see how you attached the power cylinder to the main cylinder to deal with airtightness and temperature issues.

I don't think I'll be doing an instructable on this, but it's identical to my stirling engine fan except for the following things:

Stronger bearings, I used M6 bolts cut down with a 2mm hole drilled in them]
Graphite power piston
Much taller to accommodate said piston.
Uses a 22mm pipe elbow to attach the piston
Steel flywheel from large beans tin
Big water tank

To attach the power piston, I used a 22mm pipe elbow superglued to the side of the can then sealed l all around it with RTV silicon , seems to be airtight. The piston cylinder fits in this and is sealed again with RTVAny air leaks would show up immediately because the cylinder is under water too :)

Sorry I missed your post for some reason.
