From Wired Science:
"Conceptual artist Matthew Mazzotta is using dog feces to power lampposts in a park in Cambridge, Massachusetts. (His "art" comprises) a special “methane digester” that converts
freshly scooped poop into methane. Dog owners collect their dog waste in a special biodegradable bag and
throw it into the digester –- an air-tight cylindrical container, where
the dog feces are broken down by anaerobic bacteria. A byproduct from
that process is methane, which can then be released through a valve and
burnt as fuel. In this case it is being used to power an old-fashioned
gas-burning lamppost in a park."

D & C's Biocentric Cities post is a
that features options for energy and heating systems that would reduce
our demand on natural and non-renewable resources outside the city. A
city's consumption is many times its city limit size and impacts nature
that we don't even see. My hope is that a
city can produce its own energy, heat and clean water within its city
