For the interest of those who haven’t given up entirely on biofuels, I humbly present the National Algae Association forum in Texas on April 10. This meeting will serve as an update on what’s new in this promising branch of the nascent sustainable biofuel movement: biodiesel from cultured algae (outside of biodiesel from waste oil, that is).

This week’s Renewable Energy World podcast had an interesting interview with the principal of one algae-fuel company, Solix Biofuels. Like all the companies, they have a whole array of challenges to figure out, from competitor algae to stress regimes that are optimal for producing oil. It’s actually tough to grow algae — who knew?
