When Mercedes wanted to promote its new fuel cell vehicle, instead of placing it squarely in front of everyone in the world, the company decided to make the car invisible.
In this clever publicity stunt, Mercedes wanted to emphasize that its F-Cell vehicle has no exhaust emissions, making it virtually invisible to the environment. The clever dudes did it by placing a mat of LEDs across one side of the vehicle and mounting a video-shooting Canon 5D Mark II digital SLR camera on the other side.
As you can see in the Mercedes video, even though people could still tell there was a car going by, they seemed impressed by the “invisible” fuel-cell vehicle.
