As any exhausted city walker will tell you — treading on those toes exerts a lot of energy. Turns out, it's enough energy to power streetlights.
, a New York City startup, has installed four environmentally friendly streetlights in a Las Vegas Plaza in lieu of standard lights, which are powered by methods that emit CO2 (a main cause of global warning). The company reports that the 300 million streetlights around the globe produce 100 million tons of CO2 each year.
The new streetlights are paired with ground panels that can generate 4 to 8 watts of energy simply by being walked on, depending on the pressure of each step, reports . That energy, along with solar energy collected by panels on top of the streetlights, is collected in a battery until nighttime. The LED lighting's color can even be adjusted for events and seasons.
As though that wasn't impressive enough, the streetlights also serve as Wi-Fi hotspots, wireless charging pods, video surveillance, environmental monitors, and USB ports — all powered by the solar and kinetic energy. In other words, welcome to the future.
Here's a look at the plaza with the streetlights:
Though they may have less use in a city where transportation is mostly automotive, these streetlights could have an important future in cities with high walkability like New York, Chicago and Hong Kong, notes .
