The turbine, designed by a then 15-year-old Scottish pupil, is to be used to help provide power to communities in Kenya. 

The technology's goal is to improve energy access by making it affordable, reliable and low-carbon. The prototype can be assembled without any specialist training and is intended to be used to help areas recovering from natural disasters and in rural settlements far from grid connection.

The device was first presented at COP26, after the idea was handpicked from 11,000 entries in a national competition run by the not-for-profit organisation Primary Engineer in 2019. One year later, the university team behind the project is working with other partners to bring the turbine to Kenya.

The project is one of 64 sharing £26m of funding from the UK Government's Innovate UK Energy Catalyst programme.

Macartney, now 19 and studying maths at the University of Cambridge, designed the turbine when he was a pupil at The Royal High School...
