Here's an interview on the Matter Network of the makers of the film Fields of Fuel. Directory Josh Tickell and produce Greg Reitman are interviewed. I haven't seen the film but apparently there is a piece on algae as a producer of biodiesel. Here's the section of the movie on Solazyme, another company producing biodiesel from algae. Back in January, it was reported that Solazyme inked a deal with Chevron.
The film won the Sundance Audience Award....so maybe it will make it to theatres?
