Methane gas produced by 90 farting and belching cows caused an explosion in a German dairy farm, blowing the roof off and injuring one of the animals.
A “static electric charge caused the gas to explode with flashes of flames,” police in the central German town of Rasdorf said in a statement reported by Reuters.
One cow was treated for burns.
Statistics vary regarding how much methane the average dairy cow produces.
Some experts say from 100 litres to 200 litres a day, while others claim it can be up to 500 litres, an amount comparable to the pollution produced by a car in a day, How Stuff Works reveals.
They claim the innovation could curb greenhouse gases that cause global warming.
