sorry about that last post. It's January 9th 2017 not 2016!
Most of the Listeroid discussion happens over on the Lister engine forum. We're off grid and use the hot water from the engine to heat our house. Works great and that's what Micro Cogen is about. I have to admit I still love running my 'roid and it gets run about 250 hours a year here.
Thank you Tom. Will check the lister engine forum out. I can't imagine people becoming bored with these unless they never lose grid power.
