Surprisingly the federal government has begun to study the safety issues involved with hydrogen vehicles far in advance of their becoming an everyday realty. We applaud the government's efforts since almost anyone could figure out driving around on a hydrogen gas tank may be dangerous. But at least they're also looking at how the gas would be delivered which is a major obstacle to a feasible hydrogen car economy. As I understand it, it still takes fossil fuels to create hydrogen. That doesn't seem too alternative to me. If we already have clean cars now, hybrids popping up like bunnies and innovations like multi-displacement systems, hydrogen almost seems less sensible. Safety is just one factor that will make a switch to hydrogen cars unlikely anytime soon.
