I do not think I am alone in these thoughts.
How is it we can put a man on the moon, but yet getting over petrol/diesel driven transport is beyond us?

When thinking of transport we need to consider the movement of goods.
Can you see large container lorries being powered by electric?
No - neither can I.
And then there is the thorny problem of disposing of the many worn out batteries over the years.
These are not small things to dispose of....so where do they go?

All of these things should be being investigated...as should ALL alternative forms of powering our domestic and industrial needs.
That is, of course, unless we really want to go back to the stone age.

Here is some very interesting information about this genius..he was ahead of his time.
Just in case you are interested.

McDonald's run all there lorises on reused fat from their resteraunts, I don't see how it can't be brought in on a mass scale, or make cars steam powered and run them on water

We can't grow enough sunflower or whatever oil you chose for every car in the world to run on.

How would you heat the water to produce the steam?

Pass an electrical charge through the water to heat it up

That is how to produce Hydrogen and you would also get Oxygen as a by-product.

This is not the first discussion on transport that has ended up going round in circles!

Never ending supply of hydrogen. Sea levels are rising, heat that up and we'll get hydrogen, more oxygen in the atmosphere, and more salt to put on the roads all while reducing sea levels, global warming solved

I believe the expression is "Reinventing the wheel"

I didn't think you could use sea water to produce hydrogen.
The salt breaks down into sulphuric acid and chlorine...but if you know different then I am ready to be educated.

Bio-fuel, is what you're talking about here. Quite some years ago the Germans decided to reduce reliance on pure diesel & started producing Bio-diesel & mixing it with traditional diesel at about 7%, there was uproar & no one would touch it, even the ADAC (RAC equivalent) condemned it as it would cause numerous problems with older vehicles the main one gumming up injectors & damaging engines.

Now we're x years down the line & Germany are pushing the green agenda, the % of bio-diesel mixed with normal diesel is now 10% & there's no way of avoiding it, the vehicles are better equipped to deal with the mixture & everything is just hunky dory in "Mutti's" little world.

Only problem is, that to produce the quantities required & demanded by the German governments "Targets", vast swathes of countryside have been turned over to growing maize & rape to be turned into bio-fuel for use within the reich. All well & good but that is then land that's not producing food for the populace so more imports are required to feed the masses & thereby raising cost ..... and so the cycle goes on.

That article is from 2015....and it stated that this was still in the experimental stage.
Is there any further information on what this method of obtaining hydrogen costs.
For it to be a viable proposition it needs to be economical...somehow I doubt that this is the case right now.
That is not to say that further developments in the future may not make it a viable proposition...in fact it would be good if that were the case.

2016, it's the future of power turning sea water into hydrogen fuel

In the future, we plan to work on developing a method for the low-cost, large-scale production of H2O2 from seawater," Fukuzumi said. "This may replace the current high-cost production of H2O2 from H2 (from mainly natural gas) and O2

An interesting writeup on a device I had not previously come across. However lab prototypes do not always successfully scale up to be useable as industrial processes. Also I note that it makes no mention of how much energy you have to put in to make it work, the lifetime of the electrodes, the nature and quantity of any residual products, any of these could be big stumbling blocks as is often the case.
