This is a picture I took on my way from work (bridge from Södermalm to Nacka, Stockholm). I have to cross a canal with a movable bridge. The bridge serves cars, pedestrians, cyclists and used to serve a tram before too. It is not the only connection to my city part but it is a shortcut. Ground traffic depends on the road infrastructure, the boats passing depend on the canal and water system and the capability of the bridge to open. The bridge is depending on electricity and also flow of information (request to open the bridge, stopping traffing with lights....) The bridge is part of infrustructure and supports flow of people and goods but depends on energy supply (flow) itself. I was thinking a little if I can come up with 'stocks' example to discuss, I wondered about material, water capital, or if the bridge works as a data colletion tool it can help to collect and store data (the technology in it could).
