BioAudio
Welcome to BioAudio: The Teaching Podcast. After many years teaching biology in universities in the UK and in Canada I've come to the conclusion that we can do better than text books. I always want something more flexible, that can be updated with new topics and new discoveries. After years avoiding textbooks… I've created BioAudio a collection of discussions to accompany lectures in university biology courses . So let's ditch the textbook and just listen.

Evolution inspires technology - of bird legs and heat pumps

Episode 20
In the final episode of this season of the BioAudio podcast we talk about counter current exchange - a low energy system used by birds, fish, diving mammals etc. to recycle heat, move oxygen out of water and into blood and even make it possible to drink salt water. But the same system is used in industry, most recently in the news in heat pumps which move heat along gradients to both heat and cool your home. Inside a heat pump is a clever counter current exchange system which sounds a lot like the legs of a bird legs. We'll compare these two technologies - it's evolution in parallel with climate saving technology on the BioAudio podcast. Thanks to Dr. Kevin Kerr, Silas Barrette and Dr. Leif Einarson.
