Universal History Archive / Universal Images Group via Getty ImagesThe age of huge, ocean-crossing zeppelins came to an end in 1937, when the Hindenburg — the largest craft of its type ever built —Now, more than 80 years later, the giant airships may be poised for a comeback — not for passenger service, but as an environmentally friendly means of delivering goods around the globe.
“We are trying to reduce as much as possible emissions of carbon dioxide because of global warming,” said Julian Hunt, a postdoctoral fellow at the International Institute for Applied Systems Analysis in Laxenburg, Austria, and the paper’s lead author.Hunt said the new generation of airships would get around by riding the jet stream, a powerful air current that circles the globe.
The jet stream moves from west to east, so airships would only go in that direction. Hunt imagines them taking off from the United States, for instance, and crossing the Atlantic Ocean and Europe to reach Asia. The craft would then continue west across the Pacific to return home.“I didn’t invent this,” Hunt said of the flight pattern. “The Hindenburg used to do it. They had this path which would go from New York to Tokyo and then come back,” he said.
What has changed, Hunt said, is the technology available to build and operate airships. When the Hindenburg flew, operators had only the most basic means of predicting weather patterns and the crudest materials for fabricating airships. “They used to use cow intestines to build the gas bags,” Hunt said., would make airships safer and less fragile; computerized weather-forecasting systems would let them steer clear of storms and help optimize the use of air currents.
The Hindenburg catches fire after attempting to land in Lakehurts, N.J., following its first cross-ocean flight in 1937.But for all their high-tech advances, Hunt said, the new airships would still get their buoyancy from hydrogen, a highly flammable gas that isThe possibility of another giant explosion has some pushing back against an airship renaissance.
