How are we sustainably converting elemental hydrogen into a state where it's readily storable and transportable for use in vehicles? I'm not pushing against it as a viable energy source generally speaking, but it really doesn't need to be in a car, where it's used to power an electric motor in the exact same way as a battery is, except the battery can recapture energy through regenerative breaking. I was pushing back against the implication that humanity is stupid for not using hydrogen in general, because we use a lot of it.

For the record, your all-powerful and flawless elemental hydrogen can power the grid just as readily as it could power a car. It'd be great if it were a larger share of our energy generation, for the record.

The fact that Hydrogen, the most readily available element in the Universe, is not our primary fuel source demonstrates how ignorant the majority of people on the planet are. If everyone knew, they would look at any other energy source as a complete waste of resources and demand better.

Electrolysis can separate Hydrogen from Oxygen in water. It is also incredibly eco friendly, and incredibly easy to scale up. Hydrogen as a fuel also produces water vapor as a byproduct. Not to mention Hydrogen Fusion technology for Nuclear energy production will be the way if we get our collective heads on right.

Feel free to tell me how you plan to power your theoretical public transport grid without mentioning Solar and wind farms which are are incredibly destructive to the environment to build, maintain, and operate.

For the record, I wasn't speaking about personal vehicles. Nor did I make one mention of them. But since you wish to ignore my point and change the topic: If I had it my way, no one would own a personal vehicle. EV or otherwise.

You said that we aren't using hydrogen as a fuel source, which is patently false. You must think we're burning those hydrogenless hydrocarbons that so famously exist. It's not in the form that you like, but we're literally using copious amounts of hydrogen as a fuel source and have been for decades. It isn't suddenly not hydrogen because it's attached to carbon when we choose to burn it. Plain elemental hydrogen doesn't exist in abundance in any capacity that we're capable of harnessing, which is why you have to bring up methods to create it even when it's the most abundant element in the universe. You're the one who chose to respond to me, in my comment about its use in cars, in response to someone else's comment about hydrogen in cars, in a thread about cars and somehow I'm the one who's changing the topic?

Done with you now. Take care.
