Not clear on what you’re trying to say here. The energy generated from a fuel cell is electricity. The entire fuel cell assembly is essentially a battery, using hydrogen and oxygen as the electrochemical components.
But, I think you’re trying to argue that one is better than the other. To that all I can say is we all are just getting out of being locked into a singular infrastructure (combustion engines) for the last 90 so years, it’s probably best to invest concurrently in multiple alternative energies instead of putting all of our eggs in one basket. Hydrogen has some strengths where lithium ion does not and vis versa. I’d assume it would be best to diversify so if one fails we have multiple backups. Kinda like investing money, don’t put all your money behind one horse.
By comparing people to these slurs, you enforce societal norms that indicate that the said group has less value in society.
Since humans are social creatures by nature, you are essentially dehumanizing an entire class/group of people because you can’t come up with something more clever to say.
To err is human, we all make mistakes, intelligence/sight/etc. has nothing to do with it.
