New Albany's plan is to use sidewalks as passive/aggressive energy generators.

The Sidewalk of the Future Is Not So Concrete, by Nate Berg (City Lab)
... Some cities have started to rethink the traditional sidewalk as a result. Local governments and technology companies all over the world are considering new ways of building pedestrian pathways that go beyond the common mix of cement and aggregate we know as concrete. These materials have broadened not only how cities construct sidewalks but also the very notion of what a sidewalk can be. They can now enhance walkability, generate renewable energy, and improve public safety, even as they withstand all those tree roots that have been breaking concrete slabs for decades.
