Many train stations in the metropolitan area have installed quite ingenious small bicycle pumps. In that way the pumps are always available when you are on your way home from the station, or just pass by. Also when bicycle shops have taken their pumps inside for the night.

Many places this already exists in the pedestrian streets. But what about making heated bike paths, making it even more attractive to take the bike instead of the car - even in winter? In Utrecht in the Netherlands they are considering using geothermal energy to get rid of sleet and snow on the bicycle paths.
