The Armored Dive Suit of 1911
No this is not from Pacific Rim.
The time is 1911.
The man is inventor Chester E Macduffee and he is shown with his experimental Aluminum Alloy Suit.
US Patent 989530, “Submarine Armor “, this German aluminum alloy (Duraluminum) suit weighed over 550-pounds (without the man inside! ) The cylindrical joints mounted on ball bearings allowed movement in one direction only. They do not appear to be watertight due to the fact Macduffee implemented a waterpump in the suit. This pump was able to pump water from the leg section into the sea. The pump operated on compressed air supplied from the surface. The used air from the pump then expanded into the suit and was used by the diver for breathing. The suit was equipped with a 12 section-gripper mounted on one arm and an electric light on the other arm.
This steampunk nightmare actually worked and was tested in 1915 to a depth of 214 feet in Long Island Sound.
