Chicago's iconic Willis Tower (formally the Sears Tower) is set to become a massive solar electric plant with the installation of a pilot solar electric glass project. The high-profile project on the south side of the 56th floor will replace the windows with a new type of photovoltaic glass developed by Pythagoras Solar which preserves daylighting and views while reducing heat gain and producing the same energy as a conventional solar panel. The project could grow to 2 MW in size — which is comparable to a 10 acre field of solar panels — turning North America's tallest building into a huge urban vertical solar farm.
