hat inventions and technical innovations are needed for biofuels to become a true challenge and sustainable alternative to petroleum-based transportation? This is one of the questions we put before two dozen experts from industry, universities, and environmental groups who gathered last month for National Geographic’s Biofuels at a Crossroads forum. How would you rate their ideas? Feel free to comment with ideas of your own.
Biofuels are a waste of time; I cannot vote on this issue. Any long term biomass site will suffer a massive soil degradation. The transport inefficiency is abysmal too. The only biofuel argument that makes any sense to me is algae production but the water use is really intense. The argument for direct solar exploitation seems to make more sense to me in the long run.
