Using biogas for pumps in irrigation is gaining in popularity in India and elsewhere, as the savings in petroleum fuel prices are great. A diesel pump can also be converted into a bio-gas pump used for pumping water. The cheapest way to get biogas, once a pump is obtained, is to build a biomass digester, which means biomass must be collected, cultivated, or found.
