Re: Found!! Rider Hot Air Engine UK

Not sure about the chrome effect. Also firebox seems to be missing. I would hold out for a better example.

Re: stirling engine isnt a heat engine?

Rather than heat differential, temperature differential might describe it better. Thus you will always have a 'hot' and 'cold' side whatever your definition of heat.

Re: Visual "marker" of a stirling engine?

Yep picture 2 is basically a model of pic 1. (Although slightly different design). To answer your own question do you see a visual marker in these engines? They are recognisable to Stirling enthusiasts but would they be so to your audience? The characteristic of a Stirling engine tends to be non vis...

Re: Visual "marker" of a stirling engine?

Hi Socialschism, thanks for the background on the comic book. I would suggest the visual marker for a Stirling engine (beta & gamma) would be the displacer. There was a topic in the forum http://stirlingengineforum.com/viewtopic.php?f=1&t=919&p=3429#p3418 with the following video. http:/...

Re: Visual "marker" of a stirling engine?

Would be interested to know what the Stirling engine is used for in the comic strip. Knowing this might give rise to ideas of a design that you might like to think out about. There are various types of Stirling engine as Ferracio aludes to...is the comic strip futuristic or back in time...more info ...

Re: Sterling Basics

Note that it is Philips Stirling and Philips Cryogenics that Ian SC refers to.

The name officially is Philips Gloeilampenfabrieken N.V, not to be confused with the other company with two L's!

Re: 3 foot LTD Stirling Engine

The annoying thing is there is a sign right next to the engine. I wish he had included that in the video.

Re: 3 foot LTD Stirling Engine

Hi Ian, Yes I have been looking at it and agree regarding the piston. What do you think the displacer is made of? The design is as a model LTD engine. Rather than being an attractive curiosity (as the youtube video maker wonders what it is) I would like to think of an application for it. I have long...

Re: 3 foot LTD Stirling Engine

That is a nice LTD engine. I hope you can find the builder of the engine and perhaps he can give us the plans. Is it too low an output to do useful work?
