Shooting down future airships

Who among us with even a wisp of steampunk in our soul does not love the idea of an airship renaissance? Airships are beautiful and majestic, and modern hybrid airship designs are extraordinarily capable. They far transcend inappropriate fears of Hindenberg-like disaster. No wonder some enthusiasts foresee a coming day when airships will again fly in great numbers as replacements for some fixed-wing aircraft, as new vehicles for air cargo transport, and as floating luxury liners.

Unfortunately, for reasons I explored in a series of posts back in 2011, I’m skeptical of this glorious airship resurgence. Hybrid airships work but to triumph on those terms, they need to make practical, economic sense and be better than the transportation alternatives. I’m not convinced that’s true for most of the listed applications. (The important exception is for luxury cruising: any business that’s built on rich people’s willingness to pay top dollar for great experiences can defy some of the usual constraints.)

Start with my Txchnologist story “Lead Zeppelin: Can Airships Overcome Past Disasters and Rise Again?“, then continue with my Gleaming Retort posts “Does Global Warming Help the Case for Airships?” and “Zeppelin Disappointments, Airship Woes.”
