Hi Doug >Anyone have a clue on what these cost? Nothing on thier web site!
Kirk checked it out a while back, and said this: >I went to the stirling site, an NZ company. Their engine is being >sold as a sailboat electrical generator for big bucks (Holland) >but the co. doesn't deal with individuals. :-( This was posted to the GAS (Gasification) list: >If you go to > >www.victronenergie.com > >you will find a 103 page pdf article "Electricity on Board" >explaining how the WhisperGen Stirling gen-set offers a neat >solution to providing power on board a yacht. > >Some of this is very relevant to off grid power applications - well >worth a read. > >With Striling technoplogy - there is no need to cool or scrub the >wood gas, and so efficiency is maintained at a higher percentage >level. > >Remember -- a Stirling is not a fussy eater - unlike some IC engines ;-) I hope that link still works.
