Caterpillar Drive Submarines

Follow @soilinspector Here is the technology behind Australia's caterpillar drive sub everyone should have one they operate with a compessionless rotor engine running on water as the powerplant does not need atmospheric air and runs in a sealed loop. recycling 100% of the environment in the loop.
The propulsion system is a compessionless rotor angine with open ports at each end of the combustion chamber which now is used to move water from the front to the rear of the sub producing a jet stream water pump to move water to propel the submarine.
