Habari, and welcome to Sun, Soil and Silicon. I am Achieng Otieno, and this is the show about climate technology that is actually being built, not just announced. Today we are on the back of a motorbike. Kenya has well over a million boda boda taxis, nearly all of them petrol, and a few companies are betting they can make them electric. I spent a day with a driver called Kevin, rode along for three battery swaps, and then sat down with the company to ask the question everyone skips: does Kevin make more money, or does the startup? We also look at where the electricity comes from and what happens to the batteries when they get old. You are listening on Witspeak Podcasts. Helmets on, let's ride.
