Dutch designer Ritsert Mans and scientist Peter Mooij created a wooden motorcycle that runs on algae to increase the visibility of the lesser known fuel source. “For every part of the bike, I looked to what nature could provide me with,” said Mans, who built the frame and springs with wood. He used cork for the dampeners and hemp for reinforcement.
