Stirling Cycle

[ROB FORD]

Hi guys,Rob Ford here,Is any one familiar with the Stirling cycle refrig system, I have a collague who is trying to develop a refrigerator based on this system just as a hobby thing. I do remember talking about this as an apprentice a lifetime ago, and am now looking for some info on this type of system. I am particularly interested in opinions, books or web sites I can visit with info about this.

Thanks Chemi, they look like good sites, I'll take some time on Monday and go through them properly. Now for the next question, how do you feel about Helium as a refrigerant in this application. Cheers Rob
