This is my 3D rendering of a solar powered catamaran I want to build. The whole thing would be solar powered with large electric motor and battery backup system. It would also have multiple vertical wind turbines to help generate power to the batteries as well. It’s probably about 33 feet in length, though it could be bigger or smaller. Given the scale of the bridge, it’s likely 33 feet or so long by about 15′ or so wide.
