Water, water everywhere. So why not use it to create steam?

Here's an invention Captain Ahab could love: Icelandic Hydrogen has created a ship-board hydrogen energy system that is an auxiliary power source for The Elding, a 130-ton, 150 passenger ship used as a whale-watching vessel. The company used Autodesk Inventor to model the system, which was born out of a project called SMART-H2. There's a mini-interview that explains the technology at this YouTube link. The technology isn't just intended for ships; it is being examined for multiple transportation challenges.
