To improve the standard of living of 40 agricultural and fishing communities along the waterways in Senegal by introducing affordable transportation to deliver their produce to markets – traditional vessels powered with a locally produced biofuel outboard motor. Dovetailing with the motor, a simple fuel plant will be introduced to process indigenous oil seeds into cheaper, reliable, and ecofriendly fuel for the motor.
Many small farmers and fishermen in Senegal are challenged with getting their product to market in a profitable manner due poor transport infrastructure and expensive fuel. Sine Saloum delta and the lower Casamance River region are both situated on navigable waterways and rely heavily on farming and fishing activity. Because of limited water transportation options, farmers have to walk miles along the rivers to get to major markets or ferry landing to cross the water. Many villages along the waterways that are not within walking distance have to rely on truck transportation, which is expensive and nonexistent in many cases during the rainy season. Biofuels could be alternative to petroleum-based fuels, but they must go through extensive and complicated processing before they are ready to be used in a diesel engine.
Innovation / Expected Results:
The project will introduce a simple method of fuel heating and an innovative design of power transmission. The engine uses a new technology that heats raw, unrefined seed oil straight from the cold press into the fuel tank without extra processing except for filtering and gum settling. This is done by using heat generated from the exhaust and transferring it to the fuel tank. This circumvents the costly process of making refined biodiesel. A mechanical pulley conversion gives the motor a higher torque output, thereby maximizing its low horsepower characteristics. This system provides the same propelling capacity as other outboards that have twice the horsepower output and fuel consumption. The motor is also designed to power the oil press, thus being capable of processing its own fuel.
