Why isn't this a good design?

Not only expensive but if you are using energy from a regular power plants for the electrolysis the pollution and CO emissions will be far more than if you just use the gasoline in your car.

Last time I read about it, they still had huge problems with hydrogen leaking from the storage units, has that improved? As to getting the hydrogen, electrolyzing the sea is easy enough, not cheapest way now maybe but that may change
As Deyan has said, the monetary and environmental cost of liberating Hydrogen from water is currently so high that using Petrol is probably still better. I have not seen anything about storage problems but then again I haven't been looking. :)

Yes – if we are able to use a green energy for the electrolysis this would be a game changer.

Oh, but it does. Honda has a Hydrogen powered fuel cell vehicle that it sells only in (I think) California USA, at the moment. Clickety[^] The problem is getting sufficient quantities of Hydrogen, at a reasonable cost, for it to become a feasible mainstream product.
This is dead end as well. The only efficient way to extract free hydrogen is from Methanol – so again fossil fuels. I would put my bet on the nuclear power plants plus electrical public transportation. IMO this formula is perfect for the EU, not sure for the US though.

There are one or two other methods under development using Ammonium Borate (I think, without looking it up) some variants of which can be recycled. Also some of the Metal Hydrides look promising. As concentrated research into this field is relatively new I think it is too early to call it a dead end to the same extent as storage batteries.

I would partly agree. Only partly, not from a technological point of view but because of enormous opposition to Nuclear Power generation and the problems of getting people to give up the 'freedom' of personal transport. I don't care because I have my Jet Pack and Hover Board but others seem to.

Absotively! That or a truly efficient, on a par with Photo-synthesis, photo-electrics.

I believe that eventually someone will find a way. I think the Russians have had some huge complex for fusion research during the cold war – I think the name was “Tokamak”. I hope now US will spend some bucks and continue with the experiments. Or they already doing it – I’ll ask Google.

There's also the ITER in France, which apparently costs 10 billion € over its entire projected lifetime. Which of course means that the budget will be doubled someday and they will still go over budget :) Or it will quietly die long before that time, I haven't heard much about it lately.
