A fact which every halfway knowledgeable person knew without having to invest several hundred billion dollars to experiment.
A pompous brother-in-law of mine, bet me $100 in 2009 that gasoline powered cars would disappear in five years, and that most cars would be electric powered. One more year, and I collect on the bet! Of course, he's a liberal asshat so he'll just lie to squirm out of paying. He's an idiot, and proves your point (not even halfway knowledgeable). He invested heavily in solar panels among other green things and lost big, which makes me smirk at him.
