When Ghanaian Abu Yaya wondered why his country imports all of its electroporcelain – a small but crucial component for electrical power transmission – it led to a collaboration with Cambridge materials scientist Kevin Knowles that might one day result in Ghana being able to reduce its frequent blackouts.
Researchers have built a record energy-efficient switch, which uses the interplay of electricity and a liquid form of light, in semiconductor microchips. The device could form the foundation of future signal processing and information technologies, making electronics even more efficient.
Stephanie Hirmer travelled to Moyo in northern Uganda to ask which possessions the villagers most value and why. The results will be used to help reduce the failure rate of projects that bring electricity to rural communities.
Green wall technology and semi-transparent solar panels have been combined to generate electrical current from a renewable source of energy both day and night.
