Spaces
Electricity costs less than 10p per kilowatt hour. You can charge quite a few laptop batteries for that, so I assume the notice was to do with health and safety, or encouraging people to move after their latte.
I see a lot of small odds and ends of space like this around the cities I visit. How do we use them to increase (positive) interactions, break down barriers, and increase social cohesion (or confront and resolve the differences)?
