From the free afternoon Melbourne commuter newspaper MX, using an item circulated by Reuters.
Wang Guanshun's paddleboat, made from a bicycle and four metal tanks, can get him across a pond in Hefei (Anhui province, eastern China). 72 yo Wang spent a month building his simple craft.
What I can't see is how the final drive to the water works. I can only guess that there are paddles across some pairs of spokes, but not across all pairs.
