To be honest, i think people don't realise to the fullest how this system works and why water fuel actually would be a problem.
First of all, water-powered engines are not new, it goes far back to the 60's and iirc it was a russian that invented pure water-powered engine that could propel a car. he was murdered. this repeated itself over various decades.
offcourse, the oil industry and lobby paired to it - which includes but is not limited to various governments, has quite the thing to lose when such things gain momentum. For that same reason, you can run diesel engines on used frying oil, but its' not allowed.
apart from the obvious point that there are so many people working in the oil industry, it would be a devestating blow to these peoples if you could run on tap water. it would end their careers/jobs with no prospect of another job so it'll be a blow for them and for taxpayer money. offcourse this includes some wealthy self-enriching arses up the industry chain but it's all the same though.
now the problem with running watered-powered cars is not just that, but, it is also the supply chain. the worst would be pure sea water. because if you simply look how careless humans take care of nature in search for drops of oil to sell, then imagine how they would rape the nature that is the oceans for the amount of fuel it wants to consume from it. imagine what happens to the ecological system, the wildlife, flaura and fauna.
and, not only that, but, what happens to the human beings that need water to drink and live? especially in countries like africa?
suddenly, the control of water would become number 1 priority and it would kill millions of people in due time due to thirst and control of the water supply.
after all, water would immediately become much more expensive, and people are living already in an economical turmoil.
wars are fought and countries are invaded for their oil. imagine what would happen when nobody wants oil anymore, but goes for water instead.
Besides, the claim that fossil fuels are becoming scarse is a lie from the oil companies and governments to keep more control over humans. they now have control over hybrid sales, and at the same time skyrocketed prices for these vehicles, impose taxes over environment causes, and have written additional laws to cope with.
all along the idea that these fuels really are 'fossil remains' is up for debate. i read various sources on that these oils are results of the inner core of the earth being so hot and causing lots of side effects with the earth that oil thus is a side product of the inner earth cycle.
i read that there are several former oil rigs that became 'depleted' and miraculously, after still having some oil in there, have their sources filled up from let's say 10% left of oil where the rig is drilled into, that after 10-20 years they discover the source has become 13-15% of oil again. how does that happen?
we are lied to to the deepest. the only thing absolutely true about fossil fuels is that the burning of gasoline, diesel etc. causes severe pollution side effects and environment disasters after spilling it.
