Being mobile means also being energy independent. It would have been stupid to drive around with a bike and a mobile fablab but having to find energy from the grid. So the first thing we tried to find out was how we could incorporate a battery system into our bike, knowing that the technology is constantly evolving and we need to support at least 3h of film without having to move a ton of weight. The result and instruction can be found at our Instructable and Wikifab page in the near future.
