Kelp farms and mammoth windmills are just two of the government’s long-shot energy bets

“The goal of this is to see if it’s possible to farm vast quantities of seaweed in the open ocean for a new type of carbon-neutral biofuel that might one day power trucks and airplanes. Unlike the corn- and soy-based biofuels used today, kelp-based fuels would not require valuable cropland.

While there are no guarantees, the researchers aim to design a 50-megawatt turbine taller than the Eiffel Tower with 650-foot blades, which would be twice as large as the most monstrous turbines today. Such technology, they claim, could reduce the cost of offshore wind power by 50 percent.”
