Caravans of airships riding jetstreams for freight?

The low carbon idea is a frivolous fashion, but could airships take some freight from container ships? Seems unlikely but there are visions here of giant caravans of airships lifting into jetstreams and travelling perpetually eastwards. And there are already models competing for start up funds.

Airships use a lot less fuel than jets do, but a lot more helium, which is a point that gets a mention, but not much of an answer.

How airships could provide the future of green transport

Ambrose Evans-Pritchard, The Telegraph

A Boeing 747 requires at least 70 tonnes of aviation fuel to cross the Atlantic. Mr Handley says his ARH 50 model has the same cargo payload but needs just five tonnes of fuel for the same journey, yet can still reach 300 km/h at high altitude.

Airships can land anywhere there is a flat space — they don’t need the runways and airports. They can get closer to their destination. Even landing on a river.

An academic paper from the International Institute of Applied Systems Analysis In Austria proposes using the Jet Stream to transport cargo on transcontinental routes without any need for power beyond the initial lift […]
