It's a pity break away billionaires with heavy industry backgrounds haven't heeded your sage advice and are pressing ahead regardless.

I'm all in favor of alternatives for gasoline. We just need some that don't perpetuate carbon fuel use. The mirai folks end up paying way more for hydrogen than gas, way way more in that subreddit, run into unavailability of fuel, the stations break and aren't repaired. I was quite surprised when I came upon the discussions there. When or if we can create h fuel without using lots of fossil fuel and energy it would be great. Today it's primarily companies and govts perpetuating their industrial bases in Japan that seem to be pushing hydrogen.
With an excess of sunlight hydrogen can be used to generate electricity at night to recharge mobile equipment batteries and cable powered semi mobile equipment, with conversion of hydrogen to ammonia it can be bulk shipped to large scale generation plants elsewhere.

Not especially relevant here to the current reality of large scale green hydrogen generation for direct industrial application to reduce greenhouse gas emmissions though, is it?
Californians struggling with small cars doesn't negate what else is happening in our current reality.
