The Hindenburg
One of the most brilliant creations of the last century was the super derigible LZ129 Hindenburg.
Little understood is the fact that the fire that destroyed the Hindenburg was created by static electricity and the aluminum oxide paint on the outer skin and that the way the Germans were using hydrogen was totally safe, lost hydrogen simply being vented out the top. Hydrogen is much less expensive than helium and much lighter, with much greater lifting power. The thing was vastly more specious and comfortable than jetliners; at least one of the Zeppelin airships had and had been all over the world, some quarter of a million miles if memory serves, on four diesel tractor engines. No need for airports, touch-down on any fair-grounds or football field area...
That begs several kinds of questions. What would a modern version look like? Hydrogen for lifting, modern engines, carbonfibre frame elements, graphene (totally smooth) outer skin? Could something like that be made to travel at 200 mph? Could the economics of the thing be made to work for general transportation rather than merely as a luxury service for the wealthy?
Could something liike that replace our bloated air travel system after the Covid collapse?
