I can remember about 10 years back, there was something on one of the science shows (Australian) about either air or water fueled vehicles. I forget exact details.
Apparently they were already viable at that stage and being used for forklifts in some factories and they mentioned the technology could be used in power boats and eventually cars.
I too believe that nothing stays the same & that change is inevitable. But I don't have the scientific background to be able to predict exactly what those changes will be. All I know is our current affair with petrol has really only been in totally full swing for about 80 years and it can't go on forever. It probably can't even go on another 80 years.
But there will be factions that fight that as long as they can. There are a lot of people and companies whose fortunes are tied up with oil and conventional fuels and it is going to take a fair bit of money for conversions.
For instance, let's say hydrogen cars are easy enough to produce and come off the production line, they could only be driven along routes where there were hydrogen fill up stations and I imagine that for quite a while, that could be limited. But then again, that must have been the case in about the 1920s, when cars started rolling out of the factories. There would not have been a petrol station on every corner back then, it would have taken time.
But maybe we are thinking about this the wrong way. We're imagining a world where people own cars as they do now, and drive them around and refuel etc
Maybe that won't be the case at all. I can't see us all going to 'public transport' as we know it, but maybe we'll be able to summon little automated travel pods when we need them, who knows. They won't be run on petrol though. We'll have to move on from that.
