1) People are talking about compressed hydrogen. Google it. Zubrin ironically is among them (but for other uses). Fuel cells are a much safer alternative, but far more complex.
2) The error rate for Wikepedia has been measured at only about 30% above commercial encyclopedias. The authors of the paper on this were surprised it was so low. Not good enough for research, but fine for a quick reference on a bulletin board. No general encyclopedia suffices for a research reference.
