CES Drive Time

On my walk from the Westgate hotel to the convention center I passed through the North Hall and ran into...a car show! Well not exactly, though most major car makers had room on the show floor. The emphasis was on car electronics. Shown here is prototype of Toyota fuel cell vehicle. They claim no polluting emissions, only water. Presumably this is in the form of water vapor. But did you know that the most prevalent greenhouse gas, by far, is...water vapor. Mercedes also brought along a prototype driverless car. It also had opaque windows, presumably so the passengers can't see what's happening outside!
