Back in the 80s and perhaps before, I started listening to a radio personality/philosopher called Earl Nightingale. His recording of The Strangest Secret became the first gold album for a talking program (rather than music). He was still in his 20s when he discovered the core understanding that drove the rest of his life–you become what you think about.
He had another pet theme that I thought made sense–hydrogen as fuel. It is plentiful. Its combustion by-product is water. What’s not to like (other than a huge infrastructure devoted to another fuel).
Those days are returning. Several articles have popped onto my radar screen in the past week trumpeting the theme of hydrogen as fuel.
I sense business opportunities for some business-savvy engineers.
