The P-51 in the photo above looks like a typical RC model, with a huge exception: it is powered by seawater! The U.S. Naval Research Lab has been working on ways to turn seawater into fuel, using a Carbon Capture Skid to remove carbon dioxide from the water while producing hydrogen. A metal catalyst in a separate reactor system turns the CO2 and hydrogen gases into a liquid hydrocarbon fuel. Check out the video for details!
