It takes some effort to extract $\ce{CO2}$ from air in order to produce synthetic and potentially 'green' fuel. Doesn't seawater provide this environmental $\ce{CO2}$ more easily?

  • $\begingroup$ It is not the extraction of CO2 that poses any difficulty (after all, there are many sources of it, such as fossil-fuel fired electric generators and cement production). It is the process of changing CO2 into fuel that requires energy. The question is non sequitur. $\endgroup$ – DrMoishe Pippik Oct 29 '17 at 21:23

    $\begingroup$ @DrMoishe Yeah... except the title says "Is it easier to extract $CO_2$ from seawater than from air?", and the body of the post essentially asks the same thing. The OP does mention the potential use of $CO_2$ as a green fuel, but I only see it as a helpful pointer/example (Before reading the body, I was curious to know what the OP had in mind), not the central idea of the post. So yeah, title and body corroborate (perhaps not obvious at first glance?). ;-) $\endgroup$ – paracetamol Oct 30 '17 at 0:59
  • $\begingroup$ As for closing the question, I'm unsure as to whether opt for "Primarily opinion-based" or "Too broad"... because the question is somewhere in the middle. A good question, but it might help if the OP restricted answers to specific sets of methods. $\endgroup$ – paracetamol Oct 30 '17 at 1:02

    $\begingroup$ How would you propose to concentrate CO2 from sea water in a way that is more efficient than air distillation? $\endgroup$ – airhuff Oct 30 '17 at 2:04
  • $\begingroup$ @airhuff I would not. I am asking wether or not such a method exists. $\endgroup$ – HannesH Oct 30 '17 at 22:32
