How do you charge your cell phones in rural Africa, where access to electricity is spotty at best? Here's the solution: a donkey and solar-powered mobile charging station!

Fitted with a solar panel that charges a 12 volt battery under the driver’s seat, the “HAPPY” becomes an independent, sustainable source of energy that powers cell phone connectivity, front and rear emergency lights and a small neon tube at night. Add a water filtration system, and the “HAPPY” doubles as a multi functional mobile business unit, that can empower an entrepreneurial owner, to generate income from it as a fresh water outlet, a mobile phone kiosk or a spaza shop – even after dark.
