Center for Process Innovation (CPI), a Britain-based company, released a concept video earlier this month examining the advantages of windowless airplanes. "Every year 3.1 billion people fly around the world," the video explains, "Using 80 billion gallons of fuel, and producing 705 million tons of CO2."
CPI believes that airlines can reduce the amount of materials used in building an aircraft by manufacturing windowless airplanes making them thinner, lighter and stronger. These advancements would also reduce the amount of fuel used, saving money for both the airline industry and the consumer.
There are no immediate plans for windowless passenger planes to be manufactured, but CPI and other companies continue to work on the design and concept.
