Scientists make virtual cows to research methane emissions

“As the materials ferment you end up with what we call the poo jars. That is as technical as an engineer would want to get,” says Wood.

Methane gas emissions are monitored.

“Every time the little unit here flicks, we count the flicks for the amount of gas produced,” says Wood.

Surprisingly, the methane that cows release comes from an unexpected source.

“Cows don’t fart methane. 99% of the methane comes from their mouth.”
