THESE SCIENTISTS WANT TO BRING BACK ZEPPELINS IN A BIG WAY
Here’s an explosive situation: An Austrian team of scientists are proposing an airship, otherwise known as a zeppelin, that’s ten times the size of the Hindenburg — the 800-foot German passenger airship that infamously caught fire in 1937, ending in a disaster, while landing in New Jersey.
Despite their inherent dangers, zeppelins could revolutionize cargo transportation in the 21st century, the scientists argue. For one, according to a terrific NBC News feature on the project, hydrogen-filled zeppelins could greatly reduce carbon dioxide emissions from the maritime shipping industry.
Thanks to the tenfold increase in dimensions, its capacity to lift cargo could increase 1000 fold, the team argues in a paper submitted to the September issue of the journal Energy Conversion and Management.
The airship could also be much quicker than cargo ships. The idea is to harness powerful jet stream winds at altitudes between ten and 20 kilometers where winds reach an average of 165 km/h. In fact, the proposed zeppelins could circle the entire planet in as little as two weeks according to the paper — while hauling more than 20,000 tons of cargo.
“I didn’t invent this,” Julian Hunt, a postdoctoral fellow at the International Institute for Applied Systems Analysis in Laxenburg, Austria, told NBC, referring to the idea of harnessing the power of strong air currents. “The Hindenburg used to do it. They had this path which would go from New York to Tokyo and then come back,” he said. “The jet stream hasn’t changed much in 100 years.”
But rather than relying on “cow intestines to build the gas bags,” according to Hunt, the technology to build zeppelins has vastly improved since the Hindenburg disaster.
Today, technologies like carbon fiber could greatly increase the structural rigidity of airships’ hulls. We’ve also got far more detailed weather data and forecasting systems.
Still, plenty of risks remain despite these advancements. Hydrogen is hydrogen — a flammable gas that could still end in disaster even 82 years after the Hindenburg’s demise that killed 36 people. Today’s much smaller blimps rely on inert helium gas, but it’s a resource that’s far more expensive to extract.
Hunt’s solution: autonomous operation. “The idea would be that the whole process would be automated so that in case you have an accident, no one will be injured — only the equipment and the cargo,” Hunt told NBC News.
