I don't know which is 'better' but i know Japan has been working on Hydrogen for a while and should have a car out in the near future. They will do it and are not be tied up with the redtape as over in US. Any alternatives would be great. 2 more years till the Volt and Toyota Prius goes full electrical. (Plug-In to Recharge). I heard that there are garages that can convert todays Prius to plug-in for recharge. (The wheels do that now). I'm glad the gas prices have gone down but they need to change the whole system. I absolutely don't trust any of the gas companies with how things have gone in recent years.
