UK researcher says best to give up on algae as its physiology will keep it from going commercial

In the UK, a researcher at Swansea University has said that algae are limited by their physiology from ever becoming a viable large-scale feedstock for biofuel production. By growing more algae together, required to achieve economy of scale and produce above the 10,000 liters per hectare annually other efficient feedstocks can achieve, they naturally shade each other and keep that growth from happening. He claims that investment in algae as feedstock for biofuel has not been wasted, however, as it helped to support research in understanding how to boost food and fishery production as well as nutritional supplements.
