car propulsion methods are compared in this months Automobile magazine, May 2013 issue

in 1900 there were 4192 motor vehicles registered in the US

1681 were Steam powered, 1575 by electricity, 936 Gasoline engines

1905, there were 78,000 registered motor vehicles.

Steam and Electric had double in number, but that means only about 3200 were steam and electric, and 75,000 were gasoline powered

1912, the electric started is developed by Charles Kettering

The starter made the gas engine far simpler to use for a lot more people, and this sounded the end of the difficult to recharge Electric, and the slow to heat up Steam

1915 was about the end of the electric, and 1920 the end of most steam.

1925, Stanley is done

1931, Doble (best steam engine made at the time) is done http://justacarguy.blogspot.com/2011/07/among-few-steam-powered-cars-doble.html

1941, Detroit Electric is through

the Voisin http://justacarguy.blogspot.com/2012/07/unique-look-at-automotive-design-french.html is the one from the Mullin Museum in Ventura, and is in the article because of the gas engine with the sliding cylinder sleeves. The big car is a White, and like the right side car, the Chrysler Turbine http://justacarguy.blogspot.com/2012/05/bit-of-this-and-that-in-display-case-at.html, are both owned by Jay Leno. neither the White, the Turbone, nor the Voisin are really in the article, but they make for a hell of a cool photo, and they didn't have an electric car to use. A proper selection would have been a Doble, either a Baker electric or Detroit Electric, and a gas engined car of the same era
