Electrobreather for diving
Beauty [of] under sea can enjoy variously. One of them with scuba diving. One of [the] equipments of scuba is containing tube [of] air, used to breathe underwater. Diver has to go out to surface when supply of air has almost [used up/finished]. I have an idea which early from how fish breathe. They take underwater dissolve oxygen with gill, but after some data collecting, in the reality the amount of dissolve oxygen in water is very small, so that fall short need of human being to breathe.

Later, then my idea come after seeing the chemical structure of water that is H2O, where there are oxygen element and hydrogen. Human beings breathe with composition 75 % of nitrogen and 15 % oxygen and the rest is other gas. Since Nitrogen only circulating in our body, we don’t have to add the amount of that gas... what we need to breathe is only oxygen. I have an idea to produce the oxygen from electrolysis process. In that process water is divided into hydrogen and oxygen. Take the oxygen and keep in the reservoir tube and release on the amount that adjust from our breathing rhyme at the same time as the nitrogen circulate. The released CO2 nor thrown off hand, I use the way of Rebreather which is able to process again CO2 become O2. So that people can dive with unlimited time. Question hereinafter is do human being can stay underwater prolonging. This idea can be developed to become a town below/under air... where at one time continent have been fulled by human being.
