[QUOTE=Tobba;38111580]Uhhh, let me explain this properly for people who doesnt get it: Its turning CO2 from the air and water into hydrocarbons, which should actually release a ton of oxygen that is turned into CO2 again when the petrol is burned, so the net amount of released CO2 is always 0 from doing this On another note, this stuff would basicaly require the equal energy you get out of the petrol to be put into the plant To put this into perspective 8.72 million gasoline barrels per day Energy density of gasoline is 35 MJ/L per liter according to wikipedia A barrel is around 160L, so thats 5.6 GJ/barrel 86400 seconds in a day ~64.8 kW to produce one barrel over the lapse of a day Thats around 565 GW to produce all the US gasoline demand Thats more power than outputted by every nuclear reactor currently in the world (I hope I got my calculations right) Basicaly we need to stop using so much fucking petrol, but this is technique is usefull for much more than petrol in any case[/QUOTE] Only if you're using fucking nuclear reactors to produce power and make oil you would just use the energy from the reactors instead of feeding it back into oil power plants, so it wouldn't be that high.
[QUOTE=eurocracy;38112088]Only if you're using fucking nuclear reactors to produce power and make oil you would just use the energy from the reactors instead of feeding it back into oil power plants, so it wouldn't be that high.[/QUOTE] Thats calculating at 100% effiency at 100% yield, assuming all of that gasoline is used in vehicles, you would need all those power plants to power those cars anyways In any case I think a lot of that demand goes to petrol based generators that could be replaced, but cars should still make up a significant amount
