I prefer the hydrogen system because you can get away with a relatively low pressure system and I suspect it has better energy yields, that said,
compressed air is a decent technology, and it might have a place in tomorrows economy.
One more thing: It's about time people realise the water used in a hydrogen ecoonomy dosen't go anywhere, it's just vaporised, to fall as rain
later, unless it's recycled in the actual viehicle, which is also an option. Think of your car as a water purification device, it's a possibility
with hydrogen or water electrolosis technology.
