Concept Design Plans Skyscrapers That Don't Cast a Shadow

The taller the skyscraper, the longer the shadow it casts — which doesn't always bode well for the people and businesses below. Design firm NBBJ is hoping to change that by constructing an entirely shadowless skyscraper for London, which is gearing up for the addition of more than 250 tall buildings to the city's skyline in the near future. One building looks like a gigantic, curved mirror. The glass surface of the northernmost building reflects sunlight down into the shadow cast by the southern building, and the curve of that glass allows the reflected light to follow the shadow throughout the day.
