Ecco2 (also known as self-sustained chemical oxygen generator or SSOG) is an oxygen generating system that uses a chemical process to produce oxygen from the air around us. The main advantage of Ecco2 over other methods of producing oxygen is that it does not require a power source, making it ideal for use in remote locations or during power outages.
The system consists of two main components: a canister filled with an oxidizing agent, and a catalyst pack. When the canister is opened and exposed to air, the oxidizing agent reacts with the atmospheric oxygen to form ozone. The ozone then reacts with the catalyst pack to release pure oxygen.
Ecco2 was invented by Dr. Michael J. Burns in 2001, and has since been used by astronauts on the International Space Station, as well as in many hospitals and industrial settings around the world.
