Battery vs hydrogen cars?

I agree 100%. I think over the next 20 years we will see several clean technologies come to market, and hydrogen will be among them. The main issue with hydrogen versus electric at this point is availability of a good distribution system for the hydrogen. No sense in having a vehicle that is difficult to find the gas for! Do you build the cars first, and lack availability of fuel, or build the fuel infrastructure first and have no customers to buy the fuel? Of course, the answer is to build both at the same time, but it will be a long, slow process.
