"For small farmers in developing countries, wanting to grow a crop through irrigation in the dry season, two options are open for pumping the water: manual or motorized.
For manual pumping the treadle pump is very suitable, for motorized pumping, diesel or petrol engine pump-sets are widely used.

Often farmers start with a manual pump and after having made some money, would like to move a step up to a motor pump. This, however, is often not possible, because the cost of the available motor pump-sets is beyond their means. The micro diesel, because of its unique design, simplicity and small size offers the possibility to be available to farmers for an affordable price. It seems reasonable to expect that if a low cost diesel pump-set, such as the micro diesel, will be introduced on the market, millions of small farmers will want to buy one. Apart from the low initial cost, the micro diesel is very fuel-efficient. It will run 7 hours on one liter when pumping 2 l/s, which is twice the capacity of a treadle pump!"
