Give it a fucking rest.
There are people far, far, smarter than you who believe differently than you and are working hard to deal with all of those things you mention and are having huge technological success with it.
If Edison had to deal with people like you, we'd still never have the lightbulb. It just wasn't possible. Electrifying cities and rural communities was far too expensive when we already had candles and coal stoves.
The automobile itself would never have been made. Oh sure, Henry Ford can make a car everyone can afford but how the hell are you going to drive it? Where the hell are you going to get that extremely explosive, dangerous, expensive to produce, gasoline required to run the damn thing - especially when you're in the middle of Kansas?
Why the hell do you think you have to defeat me on hydrogen? I'm not their fucking emissary; I just mentioned it as a viable option. I realize now that you know more than all of those who are working to overcome the obstacles but your fight is with them, not with me.
Just let it fucking go.
