The speed record for poo-powered buses is 77mph, apparently
Britain has several players in the fledgeling poop-bus industry, including one that literally shows people pooing, but a gauntlet has just been thrown by the town of Reading. Its very own cow manure-powered model, dubbed "Bus Hound," ran the track at nearly 77mph -- shattering the previous world mark of zero mph, because poo-bus records were never actually a thing. The UK Timing Association confirmed the attempt, such as it is, describing the bus' presence on the Millbrook Proving Ground as "quite a sight."
The model runs on biomethane natural gas made from animal waste broken down using anaerobic digestion. Reading's chief engineer said "we wanted to get the image of bus transport away from being dirty, smelly and slow." Nevertheless, he added that "it sounded like a Vulcan bomber -- the aerodynamics aren't designed for going 80mph." The mark stands as some kind of record for methane powered service buses, but it would have to top 150mph to get a Guinness World Record, according to the BBC.
