Politicians and the art of deception

Compare this video (posted by David) of Hillary squirming while she tells a whopper with the video below of McCain being brutally honest (via a comment by greyflcn in same post). Refreshing. We human beings are masters of deception, and of detection of said deception -- the result of an evolutionary arms race:

Update: I didn't realize that this is old footage before his flip flop.

Hybrid emissions: Facts and numbers

Having laid out my views in part I, let me turn to the actual data regarding hybrids -- both from an environmental and economic perspective.

How do carbon emissions per mile driven compare for various cars? The Volt is expected to be "less than $30,000" with a 1.0L engine. Compare this to the Corolla, with a 1.8Lengine (peak hp of 126; 31 mpg) and a price of $14,400. It's worth noting that this is in the optimistic, no-gasoline-use scenario for the Volt, computed below along with carbon emissions for the Volt running on cellulosic ethanol and gasoline, and emissions for comparable-sized ICE cars. Questions on the Volt's actual usage patterns remain: how many people will recharge everyday? What percentage of total miles will be on the grid, and what percentage on gasoline?
