That sounds like next to nothing, but the point here isn’t to make a commercially viable product that can be sold to the public. Instead, it’s to show that even waste product is wasted. And just to make it clear, the car isn’t directly powered by poo. Rather, that waste product is converted to electricity on the plant’s site. The car is then plugged in and is thus indirectly running on the potential energy that your body failed to convert.
The spokesperson elaborates on the benefits of reusing waste, citing a saving of US$1.3 million: “Last financial year we produced enough electricity to power the equivalent of nearly 4,000 homes for an entire year. Poo power doesn’t only help keep our cars on the road, it also helps us run our two largest wastewater treatment plants.”
Will this idea soon catch on elsewhere? Probably not, but it’ll definitely stink.
