Small Engines Enterprise

Colorado State University, 2008 - $15,300

The successful innovation of the treadle pump and its variations has increased the incomes of farmers earning less than one dollar a day in developing countries. Yet the average treadle pump lifts only 3-5m of water at 1 liter/second, requiring a farmer to operate the pump for 10-14 hours per day to irrigate half an acre. Diesel engines pump water much faster than that, but are expensive, heavy, and cost too much to run and maintain.

This E-Team is developing a one-horsepower biodiesel (or straight vegetable oil) engine that meets the water pumping and electricity generation needs of small and marginal farmers in the developing world, increasing their productivity and their income. The team has partnered with IDE, SELCO and the Energy and Engines Conversion Lab (EECL) at CSU to develop and distribute the engine. They will initially use IDE's distribution network in India, Bangladesh and Ethiopia.
