British grocery chain Tesco has wired up a bunch of cows with microphones to monitor their belches and flatulence, the Telegraph reports:
“The supermarket giant is undertaking tests on livestock at its Dairy Centre of Excellence in Liverpool as part of a project to help reduce its carbon footprint. Each cow is fitted with a microphone, attached to a special collar, which picks up sounds from their stomachs.”
Well … good.
