After the devastating earthquake in Turkey and Northern Syria, how do you collate data to aid those coordinating the disaster response? Cecilia Utas from DEEP (Data Entry and Exploration Platform) explains how important data is in disaster relief and crisis management. And Aziz Şasa from the Turkish Amateur Radio Association also explains the vital role of amateur radio as a key communication method in the region after the earthquake. High altitude communication platforms After multiple objects have been shot down in US airspace, Professor David Grace from the University of York is on the show to talk Gareth through these high-altitude communication and surveillance platforms. The devices serve many purposes and take many different forms, from balloons to airships. Electricity from human waste In the village of Lelo in South Western Kenya, 21 year old Vincent Odero is harnessing electricity from a surprising source – human waste. Using the warmth from human waste in a pit, he is making enough electricity to power his home. Wairimu Gitahi went to meet Vincent and to see his invention in action. The programme is presented by Gareth Mitchell with expert commentary from Ghislaine Boddington.
