Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

It looks as if electrolysis would work fine but is ruinously expensive. Stackexchange suggests 5,000 amps at 1.8v with 4kw of heat to be handled somehow and Quora proposes that 8 minutes of flow costs 1KWH.
Maybe oxygen concentrators could become a DIY project. In simplistic terms, it seems to be applying air at high pressure to a zeolite plug. The O2 goes through and the N2 is absorbed. Releasing the pressure allows the N2 to escape, and so the cycle repeats. (An oscillating IC engine like solution would be interesting).

              https://supply.unicef.org/s0845044.html ( during 15 minutes and 2 different net-entrances : 3 different "viewer" prices  ???  )


              " Indicative Price "  :               a. 660 USD            b. 716 USD        and             c. 754 USD   




              this machine weight : 16 Kg ( by all 3 views the machine weight stayed same !  ::) )






From industrial fabrication process management , production costs comparison  /Kg:


             heat pump                10 USD/Kg


             bread baking machine  3 USD/Kg ( selling price ratio,not production costs !)

                                       20 USD/ 7 Kg        or       20 USD/13 Kg       ? )




A non-profit oxygen concentrator/generator for 100-200 USD/ea. ff ( UNICEF 16 Kg model similar )




Can under-water breathing devices ( by nebulizer ) https://insight.rpxcorp.com/patent/US5092327A ( Est. Priority Date: 06/29/1987  )
or  https://www.youtube.com/watch?v=_kds-mWfR-Y     give ideas for simple(r) solutions ?






Societies whose can manage such cheap industrial solutions 4 USD/Kg

can also easily develop  for mass production  -under 100 USD selling price ff oxygen generator/concentrator - if : real interest !
