Transportation through airline travel poses an increasingly thorny problem for our resource-constrained, climate-changing future.

The emissions-heavy mode of transit will need to radically cut down on fuel use in any way possible. Planes will have to become lighter or risk extinction.

On the one hand, sticking windows onto the sides of planes means you have to bulk up the fuselage, which makes planes heavier, and bigger gas guzzlers.On the other hand, cutting back the weight of a given plane by even 5 percent would have huge ramifications for an airline’s profit margins, and the cost of airfare.

This leads to the fact that designers of tomorrow’s airplanes seem intent on getting rid of windows. The Center of Process Innovation has floated its own windowless plane concept, and it’s attracting plenty of attention, too.
