The problem is the amount of energy needed to convert H2O in H2 and O2, energy that I don't have back in the fuel cell (electrolysis isn't really efficient).
I'd prefer to put directly in a battery the electricity made from solar panels and wind turbines!
Alcohol instead is basically plant made so I'd assume the CO2 made by the fuel cell has been absorbed by the plant during its vital cycle.
That's a really interesting (and vast!) matter with lots of different point of view!
I really like discusing different points of view.
There is a bundancy of free solar energy worldwide for electrolysis, you could do it easily at home and store your own H2 and use it for your home and car fuel cell, in a way of being self sufficient.
The technology is already available and, for all those downers and pessimists, it is
not dangerous. Steamengines, driving, flying, skydiving etc. was "dangerous" in the early days, but we have to harness the dangers, learn to cope with it and use it the right way like all kinds of technology.
I wouldn't use a battery as a main means for power, I'd use it as a backup device such as a spare tire.
And being zero emmision self sufficient would be a global noble goal with all benefits directly for the consumer, instead that all kinds of profits and benefits go to investment companies and every thinkable businesman with their sticky fingers and greedy minds.
