A Spanish company is creating wifi hotspots built into paving stones. I really like the idea of incorporating technology into the infrastructure of cities. I think it reflects how connectivity has become so ingrained into our lives, and of course it would be great to have free wifi everywhere you go. I’m not sure about this particular idea, though. Won’t it be difficult to troubleshoot these devices if something goes wrong? And it seems like paving stones are subject to a lot of wear and tear and environmental stresses. It’ll be interesting to see if this catches on.
