| The problem with maritime operations are bubbles (Picture 1) |

The idea of the scuba diving equipment, what recycles air thru the active carbon filter would not be new. It bases the idea of the submarine, what would use the diesel-motors under the sea, without the need to use the snorkel. This equipment is known as closed cycle diesel system, and the idea of this thing is that exhaust gas from the machine would be driven thru the active carbon filter.
This filter would separate the carbon from the exhaust gas, and then this submarine could operate a long time before it must get back to surface. In the tests what the Soviet Navy made in 1950's the filter filled with carbon dust, and that caused the bad situation in the boat, because exhaust gas was polluted the air in that submarine. The better systems have particle filter, what would give extra time to use the carbon filter.
The scuba diving equipment what uses so-called closed cycle is the very revolutionary invention, and it has many advantages in comparison with so-called ”open cycle equipment”. The closed cycle means that this equipment recycles the air thru the active carbon filter, what separates oxygen from the exhausted air. And in theory, this kind of equipment could be the only tube, what has the ventilation system, what allows the gas movement to only one direction.
When exhausted air moves thru the active carbon filter, that would make this air cleaner. If this system is only the tube, that gives change to make extreme lightweight scuba diving systems. Those systems are also suitable in the work at radioactive areas, because this kind of system, what don't take air from outside are also denying the ionized Helium pass the filter, and travel to lungs.
This equipment was created for naval scuba divers for long-term operations, but it is suitable in any naval special operations, because the structure of that system eliminates the bubbles, what would uncover the scuba divers, who enter the harbor area. That kind of equipment would also use in space suit and space station air can be cleaned by similar filters, what are used in this kind of closed cycle diving equipment, because it allows astronauts to operate very long time in space. The carbon filter or chemical allows the spacecraft fly extreme long time, and also if that equipment is in the space suit, that would allow the astronaut operate very long time.
If the closed cycle system would be installed in the space-suit type suit, that would allow the diver even sleep in the suit. This would be very important if the person must wait for rescue capsule when the space station would be critically damaged, and the crew must be in space suits. Or it would give change to continue the long-term diving in the deep sea.
