RE: Taking Care of Business – Methane Digesters
I am familiar with the setup in Costa Rica. There is also one at Selva Negra in Matagalpa here in Nicaragua. I am looking into something like that here. You can run a Sterling engine off the methane and produce electricity as well. We have a German engineer here working on sustainable energy here in Nicaragua.
Yes, hooking up a generator to it is the logical next step. Jean Pain used the methane to fuel his truck, which is equally amazing. Haven't seen that one myself though... How big is that generator in Matagalpa? The one in CR you can see in the pic was a family household, with about as many pigs fueling it as there were people being cooked for.
The one in Matagalpa is actually a series of digesters. They provide fuel for roughly 200 families and for the resort. I am not sure how many animals they have but Selva Negra is self-sufficient and produces all food for the families that live there as well as for the resort. We stayed there about 10 years ago and were throughly impressed with the way it was setup.
Oh wow, such a big system...! It was about 10 years ago that I was there too (well, 9 years ago to be exact) but Selva Negra fell completely out of my spectrum. Haven't even heard of it. :-( Well, it's never too late to return. :-)
