Unfortunately this is a paywall article, but I just wanted to use this to make a point about Dirigibles (like the Hindenburgh).

If we had big ones like that, besides using them for low energy air travel for people, they would be perfect for delivering freight that is too big to transport on the roads.  I remember passing by wind turbine blades being transported back in the early 2000s which hung off the back end of a 53' flatbed trailer by another 50', and i wondered how they could make the turn radius on the interstate on ramps, which are designed for the longest possible vehicles.  All other roads are even worse, down of course to narrow streets and alleys in places like Chinatown in NYC where even getting a 40' dry box to round a corner is a major adventure in driving.

With a dirigible, you could deliver one of the new 100 meter football field size turbine blades to be mounted onto the Empire State Building to power the data servers down on Wall Street.  Can you imagine the NYC skyline with huge windmills on all the tallest skyscrapers?  Of course, the noise level would be pretty high so you'd have to walk around wearing noise-cancelling headphones, but you pretty much have to do that anyway.  It also might be the Final Solution to the pigeon problem in the Big Apple. lol.
