LOL. You're obviously not familiar with the new research and engineering in ultra-high pressure composite tanks, good to 20,000 psi, and weigh virtually nothing. Think "carbon fibers" or some of the new VERY high tensile strength polymers.
"Where is this acculator and the insulation to keep it hot going to sit?"
Probably right next to the E-Cat. Saves on insulation.
"As far as using aluminium, it would make more sense to spin turbines and use the power to reduce aluminum and run cars on mechanically rechargable aluminium batteries."
Not really. Remember, the topic we're addressing here is what can be built QUICKLY that doesn't require lots of additional technology. Ultimately, a steam/hybrid electric "does", I think, make the most sense. But that will take longer to get out of development.

Great material, Very high tensile strength, very good at keeping pressure it, not nearly as good at keeping things out, you will need a different material for your 5 star crash rating. Go down to a welding shop and look at what the tanks are made out of.
Spinning a turbine to make electricity and running on electricity is doable and they already make a DOT approved accumulator, it’s called a battery. If you don’t mind spinning the turbine all the time and have a big battery, you wouldn’t need to make more than a couple kW to have a vehicle that would meet average driving needs.
