turbine blades (c) JMT Sweden

How can we make the most of the wind? In this week's Naked Scientists, we find out how Humpback whales have inspired a new, more efficient design for turbine blades and stall-resistant aeroplane wings and how an inflatable wind generator flies like a kite to extract energy from high altitude winds anywhere in the world. We also hear how a specially-designed wind generator has helped Antarctic-based scientists save 30 thousand litres of diesel. Plus, a simple programme to cut child deaths in the developing world by 30 percent, a new technique for keeping tabs on tumours and a sugar-based solution for keeping virus vaccines fresh without fridges...
