With so many people on the planet, conservation has limited effect. What is really needed in all honesty, is a few billion to disappear and Industrial Civilization to be debilitated and downsized and transition to a more Earth friendly mode. Not holding my breath.
it will happen, and in lieu of massive nuclear/climate holocaust (which incidentally i do no longer believe in) it will be all breezy and fun! Looking forward

Ethanol? rapeseed oil?
Failed miserably many years ago
SA has peaked. OPEC has peaked. So goes the world.

Of course there is no free lunch and energy will need to be sunk into this process. But generating C8 type hydrocarbons using catalytic chemistry would be more intelligent than trying to use pressurized fuel tanks for H2, CH4 or NH3. It would also nullify any global warming effect of these fuels.

Somehow I do not believe in feasibility of economic reprocessing aerial CO2 by means other than photosynthesis.


Biofuels have little in common with industrial scale fuel sythesis using captured CO2+H2O+Energy to manufacture hydrocarbons.

Indeed, because the latter one (profitable CO2 "capture" from air in particular) is *pie on the sky*.
On the top of it energy required to convert CO2 into fuel would several times exceed useful mechanical energy produced by burning said fuel.
