First - the main kiosk in the show. Ok, it wasn't really a highlight, but it was a good place to start.
Then something a bit more interesting: a map of the district heating network in Copenhagen... on the floor in one of the booths. Cool idea!
And then... remember that this is a "Bright Green" show... lots of things about renewable energy, minimizing carbon footprints, and... environmentally-friendly pumpjacks (note that it's especially good for heavy oil and deep drilling!!)
These cards were part of a really cool game about energy scenarios - see more at http://www.our-opportunity.com/participants.html
