QuoteAlthough technically Hydrogen powered ICE vehicles provide a plausible solution to maintaining the transportation systems of our modern techno-civilization without carbon and in a renewable fashion, practically it doesn't seem likely to succeed.

Just like an electric car.  Take a water car and park it on the black asphalt of an out of business mini-mall.  Draw a chalk line around it.  Park a Tesla next to it and do the same thing.  You have just drawn a circle that defines zero emissions for both cars.  Hell draw one big circle around both of them. 

Now bow to the north, south, east, and west chanting.  Carbon free cars.  Do a tap dance.  Sing a happy song.

Enjoy yourself, and be like the half million Tesla fools who think they are saving the planet.  But do not think too deeply about this.  If you do you might harsh your mellow.  Do not think that drawing circles on a sphere enclose two areas not one.  The area inside the circle is finite.  And it is carbon free.  The area outside the circle is also finite.  That area is the rest of the planet, and no more than that.  That area is not carbon free.  That area has to supply the hydrogen.

As of 2022, more than 95% of global hydrogen production is sourced from fossil gas and coal.  Considering energy losses converting fossil fuels into hydrogen, a water car may wind up being the dirtiest car of all.

Where are you going to get the hydrogen.


You might as well be walking on the sun. 

'So don't delay, act now, supplies are running out
'Allow, if you're still alive, six to eight years to arrive
'And if you follow, there may be a tomorrow
'But if the offer's shunned
'You might as well be walkin on the sun

'You might as well be driving a fossil car
