A manually augmented road sign in Bangkok – fluorescent tube lamps affixed to a directional arrow sign increase its visibility. If only the cord running out the bottom of this lead to a battery charged with a solar panel attached to the overpass above, we’d have a neat grid-independent piece of the urban environment. Even better – if such an overhead solar panel was incorporated into permanent infrastructure, such as an outlet on the sidewalk for use by passerby at outdoor cafes, vendors, etc.
