The Park Spark Project
Here is a shot of the Park Spark project at Pacific st Park in Cambridge, MA. On the corner of Sidney st. and Pacific st.
From left to Right - Digester (where people throw in dog waste and can mix up what is inside with the wheel) - next is the overflow tank so that as people put more dog waste into the digester it can overflow into this tank and keep the digester at a constant level - then is the lamppost and light that has gas from the digester piped to it
