THE SCIENCE INSIDE - Alternative Cars

With increasing petrol prices and the UN calling for more radical restrictions on fossil fuels, we explore alternative vehicles. In our science news, Senegal struggles with containing trachoma and we discover that bees are affected by the solar eclipse. Winstone Jordaan from GridCars explains if electric vehicles are the way forward. In UnScience, poultry scientists and engineers develop a machine that learns how to talk fowl. Later on, we speak to Dr Mkhulu Mathe at the Integrated Energy Research Centre at the CSIR Council for Scientific and Industrial Research about hydrogen fuel cell powered cars.
