Let’s Use Airships Instead of Airplanes

Travelling via airplane is safe for you as an individual, but collectively all of using planes is unsafe. At ground level the emissions from airplanes are bad and are even more damaging when released high in the atmosphere (where you know, planes fly). If we’re going to survive the climate crisis then we’ll need to all reduce our use of modern airplanes.

Let’s use airships instead. More commonly known as blimps, these large airborne vessels can transport cargo more efficiently than boats or planes, they are just lacking the airport infrastructure. Lockheed Martin has recently found a way to make them more efficient and is proposing airships as a new way for luxury travel.

A paper in the journal Energy Conservation and Management published in September posits that just one airship could move 21,000 tons of stuff using almost no energy at all if we used airships to harness the free winds of the jet stream, the narrow band of fast-moving air above the troposphere, where planes fly. These winds, which average 100 miles per hour and can be as speedy as 250 mph, could propel an airship from Denver to China in about seven days or from Los Angeles to Tokyo in four, says Julian David Hunt, of Austria’s International Institute of Applied Systems Analysis and the paper’s first author.

These lower-flying vehicles, known as hybrids, are likely what we’ll see in the nearer future. Aerospace company Lockheed Martin’s hybrid prototype sports three cartoonish bubbles up front to help with navigation and engines to assist with maneuverability. The company’s hybrid design uses 20% aerodynamic lift — a lightly fuel-powered boost for a bit of a “plane-like effect” — and helium for the remaining 80% buoyant lift, Boyd says. The end result uses significantly less fuel than a plane and can access many areas other vehicles can’t.
