I think Hydrogen and Electricity both suffer from the same problems in the real world... they are both complete technological changes that require entire restructuring of the infrastructure. Basically, they are a massive leap.
Massive leaps are high risk.
I'm far more interested in hybrid stuff (of all shapes and sizes). Use internal combustion engines, and petrol, which we are all fammiliar with, but combine them with new technology to slowly, step by step, ween us off a reliance on petrol. A battery hybrid car that you only fill with petrol, but that does 100mpg easy with a 1.0l engine, but has the performance, practicality and (most importantly) price of a normal car is a much better first step.
But like I said, this is crunch time for the FIAs electric formula plans. They have asked manufacturers to put their money where their mouth is. We will just have to wait and see if all the talk actually turns into action.
