A chainsaw-wielding submarine harvests flooded forests

During the past century´s hydroelectric bonanza, the reservoirs that built up behind dams flooded massive swaths of forest. An estimated 300 million trees worldwide ended up underwater-that´s $50 billion worth of timber just waiting for the ax. Previous underwater logging attempts relied on human divers or barge-based grappling hooks. But humans can easily dive to only about 80 feet, which puts most submerged forests out of reach.
