[QUOTE="King Arthur, post: 527476, member: 31673"] Hydrogen certainly has some merits but we must remember that it's not a primary source of energy and has to be manufactured, hence the efficiency issues. In that respect it's just like electricity. The challenge we have to face is the incredible energy density of fossil fuels, which makes them difficult to replace effectively. But the real issue isn't burning fossil fuels per se, it's the population we're trying to support on a planet of finite resources. Humans have become a 'pest species' and we're fouling our own nest.
