This Gas Street Lamp in Worcestershire, UK Runs On Canine Excrement

This gas street lamp is powered by dog poop. Developed by Brian Harper of the Transition Malvern Hills community environmental group, the gaslamp has an anaerobic digester that runs on canine feces.

The new street light illuminates a residential neighborhood located in the United Kingdom. Dog walkers collecting dog poo in bags as per usual can deposit the excrement into the gas street lamp's digester, which is attached to the lamppost, and turn the provided handle. This heats up and mixes the waste. The poop is then broken down to generate biomethane, which powers the light and creates fertilizer.

The digester was supplied by Methanogen Ltd. Harper also received a grant from the Malvern Hills Area of Outstanding Natural Beauty to develop the system, which took 3 years.
