Picture yourself in an airship pushing into the northern latitudes. From the vantage of a barstool in the center of a luxurious lounge, you look through panoramic windows to see an Arctic vista scroll past. The ride is as smooth as a cruise liner cutting through a mirror sea. Above you is a white canopy, the base of the great bladder of gas keeping you airborne. Down below, a huge oval shadow glides across the pack ice.

I disembarked from this flight of fancy and came back to reality in an industrial estate on the outskirts of the town of Bedford, a couple hours north of London. For now, the airship of my imagination sat disassembled in front of me — an engine, the top section of a tail fin, a salubrious sample cabin.

Hybrid Air Vehicles calls it the Airlander: a colossal, state-of-the-art dirigible that was originally conceived as a military surveillance platform for the U.S. Air Force. That idea was scrapped as America de-escalated its operations in Afghanistan, but by then a new application for airships was emerging. Aviation is the most energy-intensive form of transport, and in recent years the industry has come under intense scrutiny for its environmental footprint. Unlike a passenger airplane, a passenger airship — buoyant and slow — doesn’t have to burn much fuel to stay in the air.

“We’ve completely normalized flying in an aluminum tube at 500 miles an hour, but I think we’ve got some big changes coming,” said Tom Grundy, an aerospace engineer and HAV’s CEO, who was showing me around the research facility.

Many of the scientific principles behind Grundy’s airship are a throwback to a bygone age, when Goodyears and Zeppelins carried affluent clientele around America and Europe and occasionally between the two. Other aspects are cutting-edge. The cambered twin hulls will be inflated with 1.2 million cubic feet of inert helium, not flammable hydrogen like most of the Airlander’s interwar forebears. The skin, a composite of tenacious, space-age materials, is barely a tenth of an inch thick but so strong that there is no need for any internal skeleton. Grundy handed me a handkerchief-sized off-cut. “You could probably hang an SUV off that,” he said. When it goes into production later this year, it will be the world’s largest commercial airliner: around 300 feet long, nearly the length of a soccer field.

But arguably its key selling point — the reason HAV resuscitated a mode of aerial transport once thought to have gone down in flames with the Hindenburg — is that it’s green. Even powered by today’s kerosene-based jet fuel, the total emissions per kilometer from its four vectored engines will be 75% less than a conventional narrow-bodied jet covering the same distance. The Airlander of course is much slower. A maximum velocity of under 100mph means that it’s never going to compete directly with jet airliners. “We tend to think of it as sitting between the air and ground markets — a railway carriage for the skies,” Grundy told me.

“When it enters service, perhaps as soon as 2026, the Airlander will offer premium, multi-day cruises to hard-to-reach places like the Arctic Circle.”

A 100-seat cabin designed for regional travel has already attracted orders from carriers in Spain and Scotland. The prototype we were sitting in, with a futuristic carbon-fiber profile and wine glasses dangling above a wraparound bar, is the central section of another configuration called the “expedition payload module.” When it enters service, perhaps as soon as 2026, it will offer premium, multi-day cruises to hard-to-reach places like the Arctic Circle. Behind the communal lounge, a central corridor will lead to eight double ensuite bedrooms. “You’ll even be able to open the windows,” Grundy said.

I’ve gone from a 20 year old 4Runner to a 3 year old Pacifica plug-in hybrid and it has changed many of my driving habits.

For my job I have a lot of deliveries in the neighborhoods of hilly San Francisco and I am curious about strategies I should use to increase the efficiency of battery driving and regenerative braking.

After a month of driving I can’t tell yet if I do better staying on flats or using the energy of the hills. And this thing is so damn heavy! 5000 lbs! (2200kg)

I’m finding that I touch the gas pedal far less and lean on the brake pedal far more, especially after realizing using the brakes won’t necessarily wear them down. But what techniques can I use to make sure I am regenerating instead of using the friction brakes?

Any other general advice about making this switch would also be appreciated. Thanks!

So I rarely take rideshare, but sometimes it's important. Today, my driver was friendly, chatty, personable, driving a brand new Ford electric vehicle. He mentioned that he had spent more than a decade selling for an auto dealership before starting to drive. He bragged about the car, the price, the fact that it's built like a tank and safe in a crash. He talked down Tesla and Elon Musk for faults and failings I'm sure most of us can imagine without effort. He had an answer for every anecdote I told about my car experiences that brought the conversation back around to the advantages of this make and model of car, including the fact that cars are significantly cheaper than a couple of years ago.

It wasn't a terrible experience but I feel bemused, puzzled, a little annoyed, a little bit impressed. It's creative if this is in fact a strategy not a coincidence.

Can anyone relate to this experience? What are your thoughts?

In the spirit of u/gdp's post on escooters, does anyone ride motorcycles or motor scooters (e.g. Vespas)?

Compared to cars, motorcycles can be far cheaper in purchase cost, gas, and insurance. Additionally, lane filtering or riding the shoulder in gridlock can prevent you from being part of the traffic holding everyone up. Going fast is also fun, if that's your thing.
