The Self Driving Balloons

How are Covid sniffer dogs, a sturdy bicycle scheme and balloons beaming down the internet getting on? We catch up with a few of the projects featured on our programme to see if they are making progress. In the UK we catch up with the sniffer dogs being trained to detect Covid 19. After promising results from a large trial, they’re onto the next stage of training. Meanwhile Wyson in Zambia has extended his bicycle purchase scheme for rural women and even had a bit of help from a BBC World Service audience member. We find out what happened after US company Loon launched giant balloons designed to beam down the internet to rural Kenya. And we hear from Dhruv Boruah, who has turned his attention from running plastic hackathons to a rather unusual underwater project.
