The picture shows how the system to turn dog poop into gas lighting works. You take your dog for a walk in the park, s/he does their business, you then scoop the poop and drop it into what is in fact a methane digester. The poop is turned into methane which feeds the light so you don’t tread on any dog poop that hasn’t been picked up.

Now, what about more public toilets for humans? In China there are masses of rural toilets on major roads which farmers set up to do much the same to human waste. Anyway, the City of Cambridge in the UK are thinking of introducing the dog poop idea so maybe they’ll be one near you quite soon?
