Giovanni Borelli designs a rebreather and fins
Last updated: March 11, 2017 at 21:18 pm
[ 1680 ] Giovanni Borelli designs a self-contained diving apparatus in which the air is recycled, believing that recirculating air through a copper tube cooled by the surrounding water should allow impurities to condense. He also proposes claw-like footwear to enable the diver to pull himself along the bottom with his feet. Despite the fact that the footwear is not designed for swimming, Borelli is credited by some to be the inventor of swim fins.
