The oxygen concentrators use Zeolite; it absorbs nitrogen under pressure; the result is air at over 90% oxygen. The pressure is dropped and the nitrogen escapes into the room and the process happens again. If you were in the tire business, this is how you get the nitrogen for tires and exhaust the oxygen.
The 1.4 grams is the amount of oxygen that can dissolve in a liter of water. Water is about 89% oxygen by weight so a liter of water would electrolysis to 890 grams of 0xygen. If I recall, this is a very inefficient way to get oxygen due to the strong bonds in water.

HYDROGEN Fuel Question? (actually oxygen?) As the virus spreads, and hospitals may become overloaded, I wonder how hard it would be to build a home oxygen generator. Just two electrodes in water and lots of DC from the EV or solar panels or the grid. Then venting the hydrogen, and breathing the oxygen if needed. Ignoring all the potential dangers (explosion of the hydrogen and poisonous gasses from the Oxygen electrode if the wrong metal is used. By my rough calculations it takes about 5 kW to generate 570 liters/hour of oxygen which is a bit over 8 liters per minute of normal breathing. That seems very high current consupmption. I must have made an error? I used these google facts: 8 liters per minute for normal breathing 1.4 grams of oxygen per liter 50 kWh to generate 8 kg of oxygen. How do those little battery powered O2 generators work?
