Oil, Batteries and Weighty Subjects‏

"We can break our dependence on oil…and become the first country to have one million electric vehicles on the road by 2015.” President Obama said this in his January 2011 State of the Union address. But right now there are  less than 180,000 plug-ins on U.S. roads today. ( Worldwide, there are only 400,000.) Less than 70,000 Leafs, 71,00 Volts. And Fisker is bankrupt.
Treason? Gridlock?
All the hope and subsidies in the world cannot overcome the physics of energy density: Hydrocarbons--oil--store 40X the energy pound for pound than does the electrochemistry of batteries. The engine-battery system of a Leaf is 1000 pounds more than the engine+gas tank of a Mustang. And the Mustang can run all day.
