Home-made biogas is the energy source of the future in rural Africa. Available in every village, to every farmer, gas is to replace ever-scarcer firewood. Here is the catch, however: How do you get the gas from few-and-far-between facilities to the many users? Determined to find an answer to this problem, a young woman engineer invents a cheap biogas backpack that users can simply strap on. Will her low-tech invention win the day?
