Seaweed holds promise as a biofuel crop. To make it cost-competitive with fossil fuels and other biofuels it will have to be grown in massive amounts. A new technique boosts the growth of kelp, the largest type of seaweed, by four times. Their contraption, called the kelp elevator, raises and lowers kelp to different depths, exposing it to different sunlight and nutrient conditions and speeding up growth. Among the climate solutions, cows eating seaweed belch less methane, and cultivating seaweed could sequester large amounts of carbon at the bottom of the ocean.
