The Park Spark Project
The design of this digester allowed for more manure to be added when the microbes inside stopped producing methane. Although, if we never added anymore, this digester would run for about three months on the manure inside.

Along with the successes of making this digester also came the mistakes that allowed us to understand how to improve this system. A few months later at the Vermont Studio Center I was able to deign and fabricate an all steal version that was about twice the size.
