In a promotion for its first production fuel-cell vehicle in Germany, Mercedes-Benz turned a B-Class hatchback invisible. Mercedes’ point was to show how the F-Cell hydrogen fuel cell powered car would be invisible to the environment, producing only water vapor and heat for emissions. Dozens of technicians have covered the whole car with LEDs. The camera on the other side of the car transmits the image to the LEDs, thus creating an invisibility effect. While on a tour in Germany the “invisible car”, has got a lot of stares.
