Scientists Working On Seaweed-Powered Cars
NEW YORK (CNET) - A group of scientists has gone offshore in an effort to bypass the food-versus-fuel debate. Startup Bio Architecture Lab published a paper claiming it will turn seaweed into a viable feedstock for fuel and other chemicals. Making fuel and chemicals from crops such as corn and sugar cane requires significant quantities of land and fresh water, creating competition for resources with agriculture. Macroalgae such as seaweed, by contrast, grow in salt water and are relatively productive energy sources because they are 60 percent carbohydrates and don't contain lignin, which binds up useful molecules in many earthbound plants.
