• Resumen

  • The lack of access to grid power means that people have to trek for kilometers to a nearby town to find a charging station, powered by diesel generators or solar panels. In Uganda, charging a cellphone can cost 500 Ugandan shillings, or about $0.20. Now London-based Buffalo Grid's basic technology, which was recently trialed in Uganda, should help cut those costs. A 60-watt solar panel charges a battery that's taken to the village on the back of a bicycle. The battery extracts power from the solar panel using a technique called maximum power point tracking.
