How to create a methane/ biogas generator?
After reading this article http://parksparkproject.com/home.html it occurred to me, not for the first time, that home owners and community groups could be harvesting a lot more energy in their own backyards if approached properly.
Anyone have thoughts on how to turn an outhouse into a methane engine? I happen to live in a place where outhouses are still quite common (think former CIS)...
How to keep oxygen out, that's the question, isn't it? You make the deposit... how to keep oxygen from getting in?
