New York Times: Dozens of companies in the US are pursuing the goal of turning algae into a cost-effective and environmentally friendly source of biofuel. As photosynthesizing organisms, algae already convert sunlight and carbon dioxide into biomass. And they can live in polluted ponds. But natural strains of algae aren’t efficient enough for commercial exploitation. That’s why, as the New York Times‘s Andrew Pollack reports, researchers are trying to genetically engineer “superalgae,” whose oily bodies can be converted to gasoline, jet fuel, and other useful hydrocarbons.
