Solar-powered projectors to transform Malawi's education

An app developer has unveiled a solar-powered projection solution designed to provide an education for one billion children in Africa.

Onebillion, a not-for-profit developers and publisher of educational apps, found a way of transforming Optoma’s ultra mobile LED ML750e projector into a tool to educate hundreds of pupils in a classroom.

Working with Cambridge-based engineer Chris Moller, onebillion installed the projector in a sturdy case with an Apple TV media streamer and an amplified speaker system to create a portable energy efficient projection solution.

As well as being solar-powered, the system produces a variety of learning resources on different topics that can be accessed from a tablet, helping marginalised children learn key skills such as numeracy and literacy.

Onebillion has already set up five 'oneclass' learning centres in Malawi, and plans to establish 200 more classrooms across the country.

The LED projector is both bright and energy efficient, meaning it can be charged using solar power, the lighter socket in a car or a mains adaptor.

“We tested a selection of ultra mobile projectors before we chose the Optoma projector but either they were not bright enough, did not have audio out or they were not energy efficient enough," said Jamie Stuart, chief technology officer of onebillion.

“The ML70e was the most energy efficient for the brightness that we needed. As the unit needs to be powered by solar energy – it is essential we have the most energy efficient solution.”

  1. Nothing that is commercially available as yet, there are some battery powered LED projectors but they tend to be around 750 – 1000 lumens which would not work in an outdoor environment unless after dusk.
