The liquids can take gases dissolved in their sine, that is to say, that this union is so intimate that at first we did not distinguish the gaseous form of the liquid form. Thus the amount of gas that can lodge a liquid will depend on the temperature, of the pressure which the system is put under liquid-gas, of the nature of the gas to be absorbed (solubility) and the capacity of the gas to absorb gases. Whichever greater greater amount of gas is the partial pressure of a gas on a liquid will absorb the liquid. To smaller temperature the capacity of the gas to absorb gases increases, on the contrary with the increase of temperature I eliminate will diminish its capacity to absorb gases. It formulates it of the law of Henry is:

where:

P = the partial pressure of dissolved gases.
C = the concentration of gases dissolved in mol/L
k = the constant of Henry, their units is J/mol, L · atm/mol or Pa · m3/mol.

Good after this reminder like podeis for seeing in the animation the air dissolved in the water can be extracted that according to its calculations is of 1.5% to smaller depths of 200 meters. This permitira with a lithium battery of 1 kg of weight, power to dive during one hour independently of the depth, being simplified this invention consists of a centrifugal machine that obtains the air dissolved in the water that takes to a stock market like in the semienclosed circuits.

A prototype already exists and it is expected in two years are possible to be commercialized the first equipment.
