The following submission statement was provided by /u/senormoll:

This English town is using a stretch of special pavement on a pedestrian path to power mobile phone chargers on a nearby park bench. Obviously the amount of electricity generated isn't going to halt climate change, but the town does hope to draw attention to the climate crisis and the role that small, creative solutions can play. Earlier this year Telford unveiled street lights powered by mini wind turbines.
