To cover the regular power failures a windmill was installed at primary school Futur du Sénégal in fishing village Nianing.
Primary school Futur du Sénégal is located in Nianing, a fishing village south of Warang where we installed a biogasplant. The school was founded by Belgians and provides education for about 850 pupils. The site consists of four buildings in which the classrooms, a kitchen and a secretariat are located. All rooms are equipped with a limited electricity grid for lighting and ventilation. The secretariat also houses a couple of computers and a server and the kitchen a fridge and freezer. Often the school suffers from power failures leaving the electricity grids useless for hours. Therefore they were looking for an renewable and durable energy source to ensure electricity in case of a power failure.
Engineering students Jeroen Aerts and Joachim Broeders looked into every durable energy source that could be used at the primary school considering all ambient conditions and in cooperation with the local organisation. Finally they opted for the usage of wind energy since the school is located near the ocean and the amount of wind is sufficient which they verified with wind measurements on site. They designed a wind turbine based on the technology of Hugh Piggott, which comprises a solid, simple and efficient turbine that can be self-built, self-installed and self-maintained and which has been applied around the world. The blades of the windturbine are directly connected with two rotor discs made of magnetic material. These discs rotate straight past a third stator disc which contains the coils and a voltage is induced. To storage the generated power they opted for gel batteries. In case of a power failure, the school can easily switch the grid onto the batteries and continu working.
