Is the biofuel craze of a few years ago really dead? This week’s guest on Sea Change Radio, Pat Gruber, thinks not. While plummeting oil prices may have flattened the appeal of biofuel in the auto industry, the air travel industry’s interest appears to be just taking off. Gruber’s company, Gevo, provided the fuel for the first corn-powered commercial passenger flight in U.S. history this month. We discuss his company’s technology, the competitive bio jetfuel landscape, and what feedstocks are likely to be used to power future flights. Then we dig into the Sea Change Radio archives to hear from longtime airline industry analyst Bob McAdoo. He breaks down airline pricing models that often leave travelers flummoxed.
