Sir Richard Branson carried his quests for an aviation biofuel and a method of extracting carbon from the atmosphere to a keynote slot at the BIO conference in late June, where he warned that humanity “could do irreparable harm to the planet” over the next 100 years. “We need scientists to come up with clean fuels, ideally not disrupting the food supply,” he said. Citing one project that derives jet fuel from aluminium and steel mill waste, Branson commented that “these are the kinds of fuels we need, or algae-based or isobutanol fuels. Biotech people are working on producing them in enough quantities, and I would urge as many companies as possible to work on those [kinds of technologies].”
