HI Folks! David House will be in Pennsylvania later this month for two workshops. These are hands on workshops including how to make and use biogas, and how to build 200 gal digester. Its a great opportunity, I think David is coming all the way from India.
He wrote the book Biogas Handbook and he is a great resource on the subject. Don't miss out.. and register soon they are filling up.
