The question was never if fuel made from algae could replace fossil fuels once made. Processes for turning coal or biomass into fuel indisguishable from those derived from oil have been know since at least WWII. The question was if it could be made sustainably, cheaply or in large quantities. A test flight doe not answer that. Oh and if you follow your own link, it has been updated. Less than 3% of the fuel mix was algae. It was mostly Jatropha - which has its own problems .
