2nd Basement Biogas digester in WV, 5th in the world.

While looking for relative information on indoor home scale biogas digesters for cooler climates in my home state of WV, I found your article on solar cities. If you're 1st in WV and 4th in the world then I am 2nd & 5th, respectively. Lol Installed & inoculated mine this past week (1st week of Oct., 2016). It is modular & scalable in both digester & gas storage tanks for summer & winter slurry supply amounts of feedstock and gas or in case something goes sour. I went with black plastic 55 gallon barrels simply because I can roll them out in the summer for free heat without having to build an active solar heat exchanger that would have to pump heat downhill or cold uphill into a digester at a windowless basement‘s lowest point. (Also, 55 gallon barrels because I can't get an IBC into my basement, lol.) I have a passive natural gas wall heater in the basement used to tale the chill out in winter so, I‘ll just roll the digester barrels toward or away to adjust temperature (the gas is stored separately away from the heater in a vented enclosure). Good luck in the future with your digester. A kindred spirit in WV, USA
