well, you still have to pay for the water

you need to us a lot of water

and it will take time

to make 1 kg of hydrogen you need like 9 kg of water

assuming you convernt all of the water to hydrogen

you do know that water has to come from somewhere

would be cheaper to make eltric cars using renewable energy as the fuel

well, you also have to use eletricity to break apart the water molecules

so, why not just use the eltricity directly

no, since you lose energy in the eletrical grid. it is more effiecient just to use the eletricity to power a car ddirectly

no need for a middle man

you need eletricity to make hydrogen from water

also, not everyone lives by a massive reserve of water

some people have very limited amounts of water

like, during a drought

*looks at california a few years ago*

yes, but the water still comes from somewhere. You also have to spend energy transporting the water from place to place

...

the water supplier to your house has to use energy to transport water to you

...

my point is that it would use less energy just to use eletric cars

i am not talking bout cost

well, when you break it apart to form hydrogen, guess what

it isnt water anymore

...

because it becomes water vapor

water vapor is still a water molecule

it is still H2O

i know

but when you break apart a water molecule it isnt water anymore

water vapor is still water molecules just not as densly packed

they use natural gas mostly

natural gas

there is only one

there

only
