Yes the title is correct - okay, maybe not an actual rucksack, but an idea I came across that is being proposed by Argentina's INTA governmental research body is to secure inflatable bags to cows backs in order to reduce methane (CH4) consumption. The way this is proposed to work is to connect a tube from the cow's rumen (where the CH4 gets emitted from) to an inflatable bag so that the gases are stored, rather than escaping into the atmosphere. These gases are then transferred into containers which have the potential to be used as an energy source. Very bizarre concept I know, but if it is a solution, could this mean we can have a burger guilt-free?
