A Forgotten Freight Transport Method Rediscovered, Aerial Ropeways

From "Aerial ropeways: automatic cargo transport for a bargain" in Low-tech Magazine:

These days, we use them [aerial ropeways] almost exclusively to transport skiers and snowboarders up snow slopes, but before the 1940s, aerial ropeways were a common means of cargo transport, not only in mountainous regions but also on flat terrain, with large-scale systems already built during the Middle Ages.***

***The advantages of aerial cargo ropeways are so numerous that it is no surprise that they are - slowly - being rediscovered. Worries about global warming, peak oil and environmental degradation have made the technology even more appealling. This does not only concern energy use: contrary to a road or a railroad track, a cargo ropeway can be built straight through nature without harming animal and plant life (or, potentially, straight through a city without harming human life). Traffic congestion also plays into the hands of cableways, because the service is entirely free from interference with surface traffic.
