You read about VW’s transparent factory (below); now take a look at Mercedes’s invisible car. Mercedes-Benz’s new zero-emission F-Cell car is being marketed as a vehicle that is virtually invisible to the environment. The reason is because it runs on hydrogen fuel cells that convert compressed hydrogen into electricity to power the motor. The only emission is water vapor. To promote this fact in a memorable way, Mercedes blanketed one side of the car with LEDs and mounted a Canon 5D Mark II camera on the other side. The LEDs displayed whatever the camera filmed, causing passersby to stop and gawk at the “invisible” car.
