The people in the photo above are walking through the coils of a “Living Machine” in Emmen Zoo, Netherlands. It is a machine that filters and cleans 260,000 gallons of wastewater per day using nothing but plants. The water that comes out is drinkable.
It was created by John and Nancy Jack Todd using the science of “biomimicry“, where innovations are inspired by existing systems in the natural world. They’ve built large scale water cleaning machines in Canada and the US.
