Since the creation of massive hydroelectric dams, vast areas of forest are often flooded. Even though the trees are now submerged, they are still viable stocks of timber for a long time to come. With that in mind, Triton Logging created the Sawfish -- world's only deep-water logging machine.The Sawfish is a 7,000 lb (3,175 kg), unmanned logging submarine that is remotely controlled from the surface. The robotic lumberjack latches onto the trunk of a submerged tree, attaches inflatable airbags to the trunk, deploys its chainsaw, and then releases the tree to float up to the surface.
Most amazingly, this machine runs on vegetable-oil-based hydraulic fuel which makes it environmentally friendly.
