Las Vegas Gets "Kinetic Tiles" That Power Lights With Foot Traffic (arstechnica.com)

An anonymous reader quotes Ars Technica: A New York-based startup called EnGoPlanet has installed four streetlights in a plaza off the Las Vegas Strip that are powered exclusively by solar and kinetic energy. The installations aren't mere streetlights though -- they also power a variety of environmental monitors, support video surveillance, and, for the masses, offer USB ports for device charging.

The streetlights are topped by a solar panel crest, and have "kinetic tiles" on the ground below them. These panels reportedly can generate 4 to 8 watts from people walking on them, depending on the pressure of the step. The renewable energy is then collected by a battery for use at night. The solar-plus-kinetic energy design is useful on those rare Vegas days without too much sun -- as long as there is still plenty of foot traffic.

    Conservation of energy? Isn't this just making the pedestrians expend more energy to walk?

      I am a physicist, and the OP has a valid point.

      Walking on a sidewalk fitted with these kinetic tiles would feel somewhat similar to walking up a slight incline. The extra expended energy would be modest, but real.

    Pretty soon now we'll reach the middle of the 19th century, and we'll have treadle powered sewing machines.

    ..but unfortunately sarge, all the surveillance footage stopped abruptly after the gunman shouted "Nobody move"
