The Zero Emission Electric Propulsion Ship is a 100-foot, 800-person ferry that sucks no diesel. Instead, the boat operates from a huge bay of lithium ion batteries, all while looking vaguely like it’s going to kill you and your family.
Just how many batteries are we talking about? Between 200 and 300 times the amount you’d find in an electric car—all for a fuel capacity of only about 50 miles.
For now, what you see here is just a prototype. Manufacturers at IHI Marine United hope to commercialize the machine by 2015 with the hopes that battery prices will be more economical.
