Re: [RE-wrenches] Infinia Stirling linear alternators generators
My involvement and knowledge goes way back so I have forgotten much. I think the unit was charged with Helium. Helium has a slow leak it seems. the units I was familiar with had no way to refill the helium charge. Also the rings or seas may be bad. The piston had rings, seals, and a long life was expected but if those seals went bad of course the power would drop off. I do not even remember the basic Sterling cycle, I think the piston did the valving such that the only moving part was the piston. Sorry I couldn't be more helpful. Thank you for the many helpful comments you have made over the years. On Sat, Nov 24, 2018 at 1:40 PM Starlight Solar Power Systems < la...@starlightsolar.com> wrote: > Thank you Hilton and Darryl.

Re: [RE-wrenches] Infinia Stirling linear alternators generators
Thank you Hilton and Darryl. That explains what I’m seeing here in Yuma: A 90kW installation that went slowly, and is now entirely, off line. These are the linear alternator design. Any chance your friend will have technical documents? Larry On Nov 24, 2018, at 11:37 AM, Hilton Dier wrote: A friend of mine worked for them. I believe they went bankrupt and/or got bought out.

A friend of mine worked for them. I believe they went bankrupt and/or got bought out. Seemed like the usual high tech startup management cluster_. Tech guys trying to do finance and finance guys trying to do tech. They had a good idea in that the 3kW engine didn’t require the complicated heat exchanger of larger machines.
