Newstime Africa writes about two Kenyan students working on a simple way to charge mobile phones using bikes.
According to the article, many people in Africa pay to have their phone charged, either from a car battery or from a solar panel.
Many bikes in Kenya come with “dynamo” chargers connected to their tires (pictured above) that power the bikes’ lights. The students’ device merely connects to that charger and uses it to power a cell phone instead. Brilliant.
