BMW i3, the official lead vehicle for all major German marathons, is accompanied by Energy Floors's kinetic energy floor modules.
Kinetic energy floor modules? Well, that's the device that generates electricity with your footsteps. Not much to be honest, but if you are able to gather a crew, then you can manage to feed the i3 some electricity.
"BMW wants the audience to be part of the runs and asks them to share their energy on the ‘Electric Avenue’. This Electric Avenue, located at BMW marathon booths in Berlin, Cologne and Frankfurt, is filled with our kinetic energy floor modules.
The public is invited to generate energy with their footsteps, in order to power the BMW i3 for the entire marathon distance of 42,195 km. We measure every step they take and show their progress on a massive screen. Will you share your energy with us in Berlin, Cologne or Frankfurt?"
Party people have another reason to switch to electric drive, it seems.
