Alternative fuel cars and a driverless future


Guests: John Voelcker and Alex Davies

Hydrogen fuel-cell cars are finally making their debut. Toyota, Honda and Hyundai all have new hydrogen models coming out but with so few hydrogen fueling stations around, most of them in California, don’t expect to see too many hydrogen vehicles on the roads for a while. So will hydrogen cars beat out electric? And how green are they? Marty gets an update on alternative-fuel cars from JOHN VOELCKER, editor in chief of Green Care Reports. Then, self-driving cars are becoming a reality. ALEX DAVIES, associate editor at WIRED, rode 500 miles in an autonomous car. We’ll hear about his trip and find out how close we are to a driverless future.

How seeds shaped the world; then gas drilling and water contamination


Guest: Thor Hanson

Springtime means many of us are planting seeds in our gardens – sprinkling them into the warming soil and waiting for them to grow and transform into vegetables, flowers, or trees. Seeds are essential to our lives, from the food we eat to the clothing we wear. Conservation biologist THOR HANSON celebrates the seed and it’s influence on natural world and human civilization in his new book, The Triumph of Seeds: How Grains, Nuts, Kernels, Pulses, & Pips Conquered the Plant Kingdom and Shaped Human History. Then, hydrologist GARTH LLEWELLYN, author of a new study linking natural gas drilling to water contamination in Bradford County, PA
