If Harry Potter had had a whole car instead of just one measly little invisibility cloak, it might have been something like this.
To promote the Mercedes F-Cell’s zero impact on the environment, the company turned one into an invisible car. The tech sorcery involved modding an F-Cell on both sides with fairly mundane hardware — cameras on the right, to capture the imagery on that side, and tacked-on sheets of LEDs on the left, to display the live feeds. The result is a pretty remarkable illusion.
Of course, I can’t say much for the safety of this thing — how could other drivers avoid you if they can’t see you? — but it’s still immensely cool. If you happen to be in Germany, you might be able to spot the invisible F-Cell as it tours the country. (Or, erm, maybe not.)
