And when it was too cool in Montreal in March 2014, you just had to hold hands: Thanks to a promotion by Duracell, Montreal got a human-powered heated bus shelter. It was located near the Lionel Groulx metro stop. All people had to do to make the heat work was to join hands with one or several other people and then whoever was on the ends had to put their free hand on a special place marked on the wall. When the human connection was complete, the heater would work.
