So Haagen-Smit decided to put aside his pineapples (he had already worked out the taste chemistry of onions, garlic and wine and had identified the active agent in marijuana) to try to solve the source of smog.
What he discovered explains why plug-in electric cars — the Leafs, Volts, Teslas and all the other models that automakers will bring out in the next few years — are appearing on our roads. Or, to be more precise, reappearing.

But the arrival in 1908 of Henry Ford's Model T turned the gasoline-powered car into an affordable mass-market product and made the electric car a historical curiosity.
