    For everyone saying it has no market… some googling finds it is intended for slow cargo delivery to places that have no existing infrastructure. Also this is a prototype, so the bigger ones will have a much larger capacity. They also say it is for disaster relief, similarly to places with no infra, or where that infrastructure has been destroyed like in an earthquake or what not.

      slow cargo delivery to places that have no existing infrastructure.

      And how much cargo demand is there in places that have no infrastructure?

      Yeah no, there’s still no market. Anyplace that has the need for cargo delivery builds the infrastructure.

      Also this is a prototype, so the bigger ones will have a much larger capacity.

      Accepted, but “much larger” in this context is going to be like 2x, maybe 3x payload. Not 10x.

      They also say it is for disaster relief, similarly to places with no infra, or where that infrastructure has been destroyed like in an earthquake or what not.

      Ah yes, just what the world has been waiting for… slow disaster relief.

      There’s no disaster relief role that this could fill that isn’t already being done better by helicopters.

      Also, the idea of sending a lighter-than-air vehicle anywhere near a hurricane or recently erupted volcano is ludicrous. Earthquake, maybe, but a helicopter would still do supply drops and rescue faster and more flexibly than a ponderous gasbag.

        Right now, plenty of places with no infrastructure usually just don’t get developed. So this would open the door to some places. And who do you think would want to go to such places. The very rich. So you can charge a whole lot to get them the cargo they want. That is how things with small market can make ridiculous amounts of money.

        And disaster relief is for PR. But with all the connections he has, I am sure he will be able to get governments or even private backers to pony up money to send the blimp into a disaster area because it is hugely visisble and makes those people look like they are helping.

    It’s not like the world is running out of Helium or anything and maybe it would be better used in scientific and medical applications than a big fuckoff airship.

    I do believe those are traditionally called airships rather than aircraft or is the renaming of lighter-than-air dirigibles to “aircraft” yet another example of Silicon Valley Marketing spinning yet-another-reinventing-of-the-wheel as innovation.

      Aircraft is a general term for basically anything that flies while being supported by air pressure (wings, jets/rotors, balloons). A rocket would (generally) not be considered an aircraft because the rocket supports its own weight (it doesn’t create lift from the atmosphere around it).

    Twelve electric motors powered by diesel generators and batteries enable vertical take-off and landing. They can propel the Pathfinder 1 at up to 65 knots (75 mph), although its initial flights will be at much lower speeds.

    Who the hell wants a 2-day ride to London?

    Archer apparently got the math on that right too, in 2010. New York to London is about 3500 miles, which would take about 47 hours at the top speed of 75 mph.

    I can’t believe they actually got enough money to build this thing. It’s like a vaporware project that somehow made it.

    The market for this must be literally dozens of people.

      I’d love to take a slow (presumably more environmentally friendly) flight like that. Limited vacation time is the only issue.

      It’s even more entertaining: it’s airspeed not ground speed, so the trip duration depends on the direction and force of the wind at the heigh it travels in (and that’s a lot worse for airships that aircraft because the formar have a much larger area facing the wind than the latter).

      So that trip at top speed would likelly be shorter than that on the way to London, but longer than that on the way back (as the predominant winds - except during the El Niño - are from the west).

      I can see this being used in international shipping if the get the cost down. Why put your product on a big ship when you can use an air ship? Also for landlocked countries.

        Not a chance. If you’re paying for air freight it’s because you need something delivered now. If you don’t need it fast, then train/truck shipping is more cost effective.

        While Pathfinder 1 can carry about four tons of cargo in addition to its crew, water ballast and fuel, future humanitarian airships will need much larger capacities.

        By comparison, the Airbus A350-900 has a payload capacity of 53 tons, and the newer A350F version can carry 111 tons.

        Even if they manage to triple the payload capacity, the A350F can carry 10x the weight.

          Airship can land and take off from virtually any surface that allows that silly baloon to fit. Not just airports or air strips.

            Sure, but so can a helicopter, which can also carry more weight and get there faster.

          If they send a bunch of them and they replace container ship traffic, however- how much less pollution is that?

          Not saying they don’t face an extremely uphill battle to scale enough for that to make sense (we all know the green angle alone won’t be enough even if it should be…)

            replace container ship traffic

            A single standard twenty-foot cargo container can carry ~20000 lbs (10 tons). This airship can’t even match half the capacity of one container. Modern cargo ships carry thousands of those containers, the largest about 24000. You would need to build 40000 airships to get roughly the carrying capacity of one container ship.

            This isn’t an uphill battle, it’s completely infeasible.

    This is the best summary I could come up with:


    As dawn breaks over Silicon Valley, the world is getting its first look at Pathfinder 1, a prototype electric airship that its maker LTA Research hopes will kickstart a new era in climate-friendly air travel, and accelerate the humanitarian work of its funder, Google co-founder Sergey Brin.

    The airship — its snow-white steampunk profile visible from the busy 101 highway — has taken drone technology such as fly-by-wire controls, electric motors and lidar sensing, and supersized them to something longer than three Boeing 737s, potentially able to carry tons of cargo over many hundreds of miles.

    This morning, the airship floated silently from its WW2-era hangar at NASA’s Moffett Field at walking pace, steered by ropes held by dozens of the company’s engineers, technicians and ground crew.

    The first lesson its engineers hope to learn is how Pathfinder 1’s approximately one million cubic feet of helium and weather resistant polymer skin will respond to the warming effect of Californian sunshine.

    At the start of September, the FAA issued a special airworthiness certificate for the Pathfinder 1 allowing test flights in and around Moffett Field and the nearby Palo Alto airport, and over the southern part of the San Francisco Bay.

    That will involve a long, slow slog to validate the new technologies and to demonstrate, to the FAA and paying customers, that a new generation of super-large airships can match the generally excellent safety and reliability record of today’s commercial jets.
