Point taken, but since we're sitting here on the brink of commercial space flight, and we don't have unlimited resources, (energy or raw materials)
extraction from other celestial bodies is going to be a requirement for the future regardless. It may well become feasible and cost effective to
extract methane from Titan's atmosphere, once asteroid and moon mining become cost effective. It's certainly not right now. But, like I said,
commercial space flight is in it's infancy.
At least, we're headed the right direction on that front.
As far as fuel cells go, what they don't tell you is that it takes more energy to produce the hydrogen than you'll ever get back out of it. Hydrogen
is really more of an energy carrier than an energy source, like oil.
