Taking inspiration from President Kennedy鈥檚 Moonshot which united people around a goal to put man on the moon and spurred the development of new technology in the 1960s, the Earthshot Prize is centred around five simple but ambitious goals for our planet. Chhavi Sachdev profiles more of the prize nominees from all around the world.

This week Chhavi concentrates on the innovators working to reduce waste, provide clean water and develop clean energy solutions for communities without access to power. Japan is notoriously prone to natural disaster which makes it a perfect testing ground for disaster-management solutions. The Wota Box arose from the urgent need for clean water in locations hit by earthquakes or tsunamis. Using the latest techniques in artificial intelligence it controls a series of filters to remove pollutants and provide essential washing facilities where they're needed most. In Nigeria, Olugbenga Olubanjohas invented a portable battery which can be rented from a vending machine to power mobile phone chargers and laptops, bringing modern communication options to some of the poorest areas of Africa.
