Also, back in the late 80s, Dean Ing wrote a sci-fi book called “The Big Lifters”, where he built a whole multi-modal transportation system around hybrid airships.

    Helium filled airships are no problem, but the biggest problem with them, is control. Many years ago at Hatfield , a British Airways Airship landed on a small strip of land. From there about 8 passengers got out, as it was their destination. I was just one of about 30 strong lads on the ground holding onto the main rope in the front of the airship, and we struggled to keep her on the ground. Obviously as the airship emptied her cargo( passengers), the aluminium gondola became lighter. The lift being constant, it wanted to lift up. It was a calm virtually no breeze summer afternoon, and we /the captain too, had a great deal of problems keeping the airship from just lifting off the ground. Once some more passengers filled it, it became easier to control. Then when it needed to take off again, it used to ducted fan engines acting downwards to help her lift off the ground.
    Now this was a calm balmy summers day, and I was amazed at the lifting power of this airship, and thus also the difficulty trying to control it, if the wind picks up , even a bit.
    Thus although they can lift and fly serenely and probably with less noise and pollution than a plane or helicopter, You are even more at the mercy of the wind, than a plane or helicopter. Providing your journey is not against the wind, once up in the air, it wont cost you much in fuel! Should they be brought back, that depends if they can solve the endemic control problems just highlighted here!

      I imagine modern airships would need to have mechanical means of being weighed down or releasing and gaining levels of gas without waste when landing and taking off.
      Maybe there could be some clamps that rise up into the air to grip onto the airship and slowly pull it down pneumatically. I imagine we could also have more and better propellers to hopefully stabilize the airship in choppy weather.
      I must admit though, I have a hard time seeing an airship being able to operate properly in any kind of storm. I could just be lacking imagination on the subject.

    Airships have been trying to make a comeback for decades. In 2007, I myself was involved in an airship startup. We wanted to build a 500 meter long rigid body airship for cargo. Then after market analysis we settled on smaller ships to serve as sky cranes and tourism airships. The same ideas mentioned in this video. We even spent a lot of time on the buoyancy gas compression problem. Back then, we were looking at competitors such as the SkyCat (which is still to this day, "proposed"). It's interesting to see, in 2023, how the revival of airships is still in the planning stages. Even more interesting when you consider that they did have their heyday once. So it's not like it's a purely theoretical idea.

    • @McSlobo
      @McSlobo ปีที่แล้ว +21

      I've been playing with this idea about sky trains, i.e. a chain of airships linked together so that it's built of multiple sections and linked so that drag is minimized. What do you think would be the biggest problem with that, aside of maybe side wind which would likely be hard? They could be gigantic, but on the other hand, smaller ones could be used on low altitude and they could be perhaps pulled / powered using a some sort of cable system on ground, but that's a bit different concept altogether.

    • @BQvler
      @BQvler ปีที่แล้ว +12

      This is very interesting - would you be able to share the reasons why you moved away from the idea of using them for cargo? Concerns that come to mind would be; the fear of the industries inability to adapt / get on board with such an idea, or backlash from citizens not wanting their sky obstructed by large cargo airships - but that's just me guessing, I'm quite interested in what you gathered during your research!

    I've been following for some time the rise and fall (literally) of Airlander - the UKs most recent attempt to get airships up and running again - and it isn't as easy as it sounds. The use of helium rather than hydrogen means it's not as efficient as the old pre war airships and even modern designs still limit their efficiency. More importantly, as you noted, helium is in short supply and I don't see how you'd source that limited supply without the unexpected demand dramatically increasing the price. Airlander has decided to focus on a very exclusive market to try and claw back the millions that investors (including Iron Maiden lead singer Bruce Dickinson) have made over the years. And as someone who used to have blimps fly over my head as a child (I lived near the Cardington Sheds) they struggle in even light winds. As a regular and reliable means of transporting large quantities of cargo over vast distances - especially as the climate becomes even more aggressive - I just can't see it happening.
    Btw: Those great big 'sheds' seen in the Airlander video are in Cardington, housed the original R100/R101 series and was briefly the home of the Airlander. They're expensive to maintain and are now owned by Warner Brothers - I believe that one even appears in the background at the start of The Dark Knight Rises.

      8% lift difference, while it is an issue that needs to be solved later, doesn't seem like it would affect the early development of large airships too much. The cargo market is so large that I feel like there will be enough interest to sustain a rather long unprofitable periods while development continues. The wind issue seems like the largest problem.
      Btw, I don't think hydrogen is as big of a problem as it was. newer structural materials, and especially new propulsion methods such as hydrogen fuel cells can be managed very easily to make fires close to impossible, especially when you specifically design them around fire safety. Also since it is cargo ships, most people probably care a lot less if one goes down every few years.

Helium is also one of the few genuinely non-renewable resource on Earth since it's an element (cannot be made via chemical process), and raw Helium is light enough that it escapes the atmosphere into space so it will never come back to us. We can technically make them via nuclear fusion but you only make a tiny amount from it (not to mention you may need more helium to cool the superconducting magnets anyway). Meanwhile, Helium has a unique role in science and engineering and medicine and I don't think we know of a viable alternative for some of its applications.

    One thing I always thought airships could be used for was SAR operations in regions where people get lost during normal weather, the thing can loiter over their last known location and send out camera drones to increase its effective search area, and if they’re conscious enough to signal, it’s impossible to not notice the massive dirigible in the sky and know where to direct their signal.

      As it turns out, while airships CAN stay in the air virtually for free, in order to stay in one spot you need to spend fuel to resist the winds. Also, if weather becomes too bad and winds becoming too strong, you need to land. So, on practice is very hard to exploit their long loitering time.

      First and most importantly hot air has 35-40% the total lifting power of hydrogen/helium. So you hit a point where structural weight exceeds lifting capacity increase with size much sooner.
      Second because the envelope needs to be very lightweight it is also very thing and a poor thermal insulator. So hot air-craft loose a huge amount of energy and are very inefficient. Meaning that even a perfect theoretical max solar panel would be unable to gather energy faster than its consumed.
      Also there is the extra problems like panels would have to be integrated into the skin but they hate heat so they need insulation from the heated envelopes but that adds weight and structural problems ect ect.

      The issue was not so much of it being a horror Hindenburg had flown over 300,000 km without fault. Consider how many civilian aircraft had crashed and burned before reaonably reliable tri-motors and the DC3 came on the scene. Far more fatalities.
      The issue was that in the late 1920's and early 1930's competitors for duralinium- the Zeppelin works Aluminium alloy- was now in demand by the new far more rigid, more reliable, faster and cheaper metal skinned aluminium monoplanes. One Zeppelin used far more aluminium than several aircraft that could carry equal load, further and faster. This is what truly killed the airship- and remember the massive size of the airship makes it extremely vulnerable to wind, to currents, updrafts and down drafts- so in some cases lift without thrust is self defeating. As we massively improved thrust, and lowered drag- we got massive payoffs in lift.

    As an occasional hot-air balloonist I'm naturally drawn to airships; however, the proposed cruising speed of 90 km/h could easily be counteracted by high wind speeds. Airships would have to navigate around storms and fight against side winds that would considerable lengthen their flight paths and increase fuel costs. High or turbulent winds at arrival ports would also cause delays or make landing difficult.

    I learned something about airships in the US when I lived near a Goodyear Blimp hanger and spoke with one of the tenders. Apparently, quite a few people take pot shots at blimps with firearms. While unlikely to significantly damage a rigid airship, it does pose a potential danger to passengers.

      What? VR is not a prohibitively expensive hobby to get into even now. You can get a Quest 2 for $300 and it provides an acceptable experience. Motion sickness is something that people have been shown to get used to the more they use VR, myself included. I would argue the lack of adoption for the Quest has more to do with Facebook being a generally awful company and locking those devices down to their terrible ecosystem.
      Beyond that, have you used a Valve Index? The hand tracking on that is phenomenal and the weight of the device on your head is already at an acceptable amount as it is. It is an *extremely* immersive experience that is not too far from making it to the vast majority of consumers. Given more time for ludicrously efficient chips similar to Apple's M1 to make it into headsets, it is absolutely only a matter of time before the cables go away entirely while keeping good enough battery life and excellent hand/eye tracking. The requirement of base/tracking stations is probably going to go away at some point, too, although I have no idea how far away that is. Once that point is reached, living space won't matter that much anymore as you'll be able to go outside or into your basement to have enough space for VR. Laptop CPU's and GPU's are already good enough to drive many of the games people will want to play in VR, so there won't be much cost associated with computing power.
      Also, take a look at Apple's AR headset they're working on and how phenomenally well their eye and hand tracking technology works - the fully wireless immersive experience is coming. VR is already a feasible market that is here to stay for many years to come, and it is likely to become much larger within a decade or two.
      30 years ago, this seemed *worlds* away from what was possible at the time, much like airships still seem improbable if not impossible now.

For luxury civilian travel I could imagine seeing airships taking to the skies again. The point about dirigibles being able to access locations that are remote or otherwise extremely difficult to get to is interesting though. One of the fairly significant differences is that airships don’t suffer from bottlenecks in locations like the Suez or Panama canals.

    I conducted an economic study of airships years ago, and while some items may have changed, the fundamental challenges remain. The most significant financial hurdle for airships is the crew cost per hour. This hourly cost is comparable to that of planes. However, airships take considerably longer to complete journeys, so they have higher crew costs.
    For planes, fuel (30%) efficiency is the critical factor in determining operational costs and profitability. Staff costs are about 10%
    Airships, with their lower speeds and different propulsion systems, have potentially lower fuel costs and higher crew costs due to longer journey times.
    If a plane on the Atlantic run is now about 8 hours, an airship takes about a week. For an airship going a week required at least two or three shits of crew which will add more to the cost.
    Trucks still maintain a significant cost advantage over airships and planes. Their operating costs remain a fraction of those of either air transport option, primarily due to lower fuel consumption, simpler infrastructure requirements, and more flexible staffing needs. Plus, trucks are less dependent on the weather.
    There might be specific niche markets such as the military or tourism where cargo needs to be transported in remote areas with limited infrastructure where traditional transport methods are impractical

Ideally, we'd leave the whole lot alone, but you might be able to partially protect large swathes, by removing the valuable timber, leaving no incentive to cut the rest.

It might even be possible to dispatch the leaks along the way. While it should be safe enough to travel with proper safety precusions, this design might help regaining trust in hydrogen, since it is overly safe.

      For helium this partly works, but you still have the significant problem that you would need to have these helium facilities at places to land, which is in direct opposition to the whole benefit of airships that you don't need extensive infrastructure at the place you are landing. It's simply way easier to just balast the ship. For hydrogen, building fuel cells that can turn these very high amounts of hydrogen into electricity in a feasable amount of time, is basically equivalent to building a powerplant on board. And that obviously defeats the purpose of the airship as well, in addition to somehow needing to store that energy or connect it to the powergrid, which again uses a lot of infrastructure (you can't just connect these amounts of energy to the grid directly, you'd need a powerstation to do that or the grid will overload and basically fry your computer at home if you happen to live close to offloading). Hydrogen is also quite inefficient to make electrically, so you'd also waste a ton of energy turning electricity into hydrogen and back again all the time. At that point you might as well just use a plane. And that's not even talking about the safety concern mentioned in the video with constantly on and offloading hydrogen in an airship.
      So yeah if you think about it shortly it might make sense, but if you think about it a bit longer, you'd soon realise that just adding balast is a far easier way to deal with the problem.

So you need at least some lighter than air gas to reduce the pressure differential. Even if you don't make it perfectly airtight and just 0,1 atmosphere, that is still 0,9 atmospheres of pressure on the construction. Without some kind of ultra light and ultra strong material, that just isn't feasible. Any steel construction would either collapse in on itself or be so heavy it never lifts off the ground.

    Two good ways to solve the problem of off-loading cargo causing the airship to shoot upward. 1. Mooring lines could be lowered to tie the ship to the ground long enough to compress the helium to effect the correct buoyancy, or, 2. lower the cargo, as depicted, on lines until the cargo touches the ground, then not releasing the cargo until the compressor compresses enough helium to make the lines lax at which point there's no longer any danger of the ship shooting upward. Then release the cargo and the airship could take off.

      They shouldn't try making it with enough gas volume for lifting the products. They need to make a new container for the products, and use the air ship just a net/holder of the products. Basically fill the containers with the gas needed. No need to worry about the weight loss and raising, or lowering of the ship. If something goes wrong with the product container it can just be dropped with chutes. Makes it safer, and more capable. Plus a simpler solution is always the choice. Not to mention the ship won't technically be changing in weight.

      Lastly, I completely agree that trains have not always been as safe as they are now. Given your further clarification, what I think you are trying to get at with your comment is something like "Had airships had the same amount of time and resources invested into them as trains, they would be much safer now".

    I have thought much about airships (because of how, you know, they're totally AWESOME) - and AFAIK, the solution to basically all inherent problems in their development has already been arrived at by some field of engineering since their century-old heyday.
    Here are some problem/solution examples:
    -- How to control lift while loading/unloading:
    Make the craft less than neutral in buoyancy, then hold level using large rotors. Not propellers, mind. Think of helicopters, not airplane propellers.
    These can be mounted on tilting nacelles (V22-like) and their lift may be very quickly adjusted by means of collective blade pitch.
    You'd only need them at full power during that moment of instantaneous mass change. As the rotors hold the craft in place, the pumps have time to de/compress lifting gas and restore the craft to a neutral unpowered state. (this isn't a new thing, it's called a "Helistat")
    - bonus: you don't even need motors to tilt these pods, only a brake to lock it at a chosen angle, then using cyclic control of the blades, one may torque the whole nacelle as required.
    -- How to assemble a 500-ish meter long craft (without even larger hangars):
    A recent innovation in civil engineering is the concept of self-assembling structures. It is conceivable that a rigid airship can be built of lightweight (carbon fiber, why not?) lattice sections. Comprised of linked rods and spars, that hinge and interlock into position, unfolding into the fully rigid frame of the ship.
    A very large craft can then be inflated, just like a blimp. As the skin-envelope (with the structural bits loosely attached) assumes the correct shape, the frame linkages are locked together and the craft now has a fully rigid outer hull.
    - bonus: You don't need to fill the craft with actual lifting gas during this stage. Regular Air can be pumped to inflate the skin into, then once the structure around it is locked in and rigid, this can be dumped and the floatation tanks filled with the lighter-than-air element of your choice.
    -- I grew up watching Captain Planet. Can I have my airship all electric?
    An all electric airship has the unique advantage of a surface area possibly larger than other vehicle known to man. Why not cover that big empty (besides advertisement) space with solar panels? There'd be a significant trade-off with weight for perhaps not the best performance benefit. There may be a sweet-spot that pays off though, or if nothing else, a Hydrogen lifter can use its own spare lifting gas in fuel cells for the safety of non-combustion motors.
    -- But, Hydrogen does go Boom, dunnit?
    Thing to remember is: You can't have a fire if you don't let oxygen in. That's actually a lot easier than trying to stop Hydrogen from leaking OUT. Seriously, that's actually the main problem with Element #1 - Being highly flammable is surely inconvenient, but if you can figure out a way to just keep from oozing out between the very atoms of your container, (yup, it does that) chances are, then you got a reasonably safe vessel that isn't too likely to re-enact any infamous newsreels.
    During WW1, the brits had one heck of a hard time actively trying to set German bomber airships ablaze. Despite being filled with Hydrogen, it took hundreds of specially loaded, alternating ball and incendiary rounds fired from a machine-gun, focused on one small patch of the ship in order to get enough gas to vent out, so that it'd mix with air and finally ignite.
    It took them several attempts to pull this off. So it goes to show that "Oh, The Humanity!" isn't so much the default end state for any Hydrogen airship as ppl tend to think.

    • @solarissv777
      @solarissv777 5 หลายเดือนก่อน

      regarding the last point: what if we could not bother of escaping hydrogen that much? Basically have hydrogen in the internal ballutes surrounded by nitrogen, hydrogen will inevitably escape into the nitrogen atmosphere and float to the top of the outer shell, but then, periodically, the gas (nitrogen + some hydrogen in it) from the outer shell can be pumped through the hydrogen fuel cell, thus removing the leaked hydrogen. Fuel cells can be also used to control buoyancy, by processing hydrogen from the ballutes themselves. And when you need to increase buoyancy, you just top the ballutes from high pressure tanks. You could use helium instead of nitrogen for the added lift, but it would be much more expensive.

      Conventional airship cargo-carriers experience instability issues when loading and offloading cargo. The instability in buoyancy (levels); created by the fluctuating mass of the cargo, as well as unstable air-currents (especially at higher altitude), makes conventional designs for airship cargo-carriers inefficient, unstable and potentially unsafe... when compared to alternative modes of cargo transportation vessels, e.g. conventional cargo-ships that travel via a body of water/sea.
      When all is said and done... I have come to realize that the technology should be paired with 'vertical', cargo-transport carries, i.e. [droned] helicopters. Helicopter technology should be incorporated with Ai; so that the drones will be outfitted with cargo (of specific weight/mass). With their proven prowess in vertical takeoff, they will be utilized to safely mount cargo on a giant airship (said cargo will [obviously] need to be spaced/tired-down and stationed relative to each other. Inspiration from the hexagon shape should aid the intended 'fair and even [weight] distribution' of mass, across the storage site within the airship). Like an orchestra, when coordinated, the swarms of vertical [helicopter] drones (coordinated & assisted Ai; will take the shape and form of a 'helicopter', for its vertical functionality... they will double and function as integral, and additional transportation-carriers) will 'double and function' as 'construction-pulleys'; in their purpose in safely and relatively steadily mounting cargo onto the large storage site (that will be situated on top of the airship. I envision a small, but functional runway built on the surface of the airship. It is in this additional, supportive function that the airship will resemble an "aircraft carrier, battle ship"). New and emerging technologies will facilitate this mode if cargo transportation.
      NOTE: When all is said and done... When we take a step back, and observe the construct in action, its coordinated functionalities and mechanisms will resemble the (relationship and transport mechanism) 'worker-bees and their beehive'. Through further research and development of the quantum mechanics; that is at play, and is responsible for buoyancy (its essence is [efficient] mass/weight-distribution within a [specified] medium volume)... It will be possible to reroute/engineer buoyancy (how lighter than air gas behave), i.e. how mass is distributed within a specified [enclosed] medium-volume/volume of a specified medium.
      REMEMBER: that buoyancy takes the path with the least resistance. Point is, if you can manipulate/[quantum] engineer how lighter-than-air gases behave, you will have an easier time using Ai to coordinate their behaviour (with greater efficiency and precision, e.g. making lighter-than-air gases even lighter; manipulating their mass at the quantum scale). Were such endeavours researched, developed and refined to an art, then what we will be left with are the components to anti-gravity technology and [quantum] know-how.
      NOTE: There was a successful scientific experiment; where Rubidium was used to give additional mass to the photon. This resulted in slowing down the photo. The experiment supported the feasibility of hard-light technology. The essence of the experiment was that the mass of subatomic particles could be altered/manipulated to bare desirable outcomes. That research should have been concocted with quantum mechanics in mind. Engineering at the quantum scale is exciting and bares monumental possibilities.

      Many of the applications are already covered by helicopters, trains or ships. No landing pad? Use a Heli. Still need to transport lots of stuff? Build the appropriate infrastructure, it'll be paid of quickly with the volume of good you are moving. You either move a lot to populated areas, or little to remote ones. There are very few applications for moving lots of stuff to remote areas. Literally the only one I can think of is extreme disaster relief, which happens rarely and unpredictably.

      At 15:18 the simplest solution is: instead of a compressor that compresses the gas all you need to do is cool down the gas because as gas expands from getting hotter it spreads out which causes the blimp to store higher into the sky but once gas starts cooling down it starts becoming more centralized (meaning the gas gets closer together) causing of the gas within the blimp to not as effectively hold the blimp up in the air, And this causes the blimp to sink down to the ground it's as simple as that! 😅😅😅😅😂😂

    I wonder if they could fit each Sky Whale with a Baleen-inspired ballast system.. Fly through clouds to collect moisture in the baleen filters that could line the front of the Dirigible, separate the Hydrogen from the Oxygen to supplement the hydrogen supply, and store or release excess water freely as mist/rain. this would effectively give them a swim-bladder (or flight-bladder?), and even allow them to refuel if they land on water.
    Edit: I also just realized/remembered that Oxygen would also be created/released when separating the hydrogen from the water, and storing/pressurizing oxygen and then releasing it upward (or in other directions with an adjustable system) would be a good and as far as I know, environmentally safe way to add precision to landing maneuvers or speed up descent/ascent when needed.

      I'm mostly concerned that the amount of water would be insufficient when converted, as I'm not sure what all the water to hydrogen conversion rates are, and the amount gather-able from atmospheric moisture vs the amount of hydrogen needed for lift may be vastly insufficient for all I know.

    In the beginning, I think a reason why trucks are so vastly popular is because of their flexibility. They don't require airports, waterports or railway stations. They can use the existing road network for transport and require their separate infrastructure like trains... You'd need to use a truck for the last mile anyways when transporting goods by train for example. That's why many companies opt for truck transport end to end as it also simpler to organize and more flexible (train networks are not always open to use, but trains run on schedules; trucks can leave whenever they want).

      Cargolifter went bancrupt not only because of lacking financal support. They underestimated the problem of using diesel engines for propusion and dynamic balancing (which momentarily would use more horsepower than propulsion). There is no airworthy - certified - diesel engine of that size. The certification process of - say - an already existing MAN engine would cost a fortune and last for years. But all the planning was focused on diesel engines. The engines use up diesel, so, the airship looses weight. To counter that loss of weight, Cargolifter planned to condense the exhaust gas and keep the water that is also produced when burning diesel. And there would be more water than used up diesel. You could simply spill the surplus water. The Zeppelins of the old days did exactly that trick to cross the Atlantic (exept of using petrol engines - no big difference in that).
      So, Cargolifter changed the planning (far too late in the process) to use already certified turbine engines - like in helicopters. The exhaust gas of such a turbine is much hotter than diesel exhaust coming out of a piston engine. And there is no way to cool ist down sufficiently to condense it. The proposed reach of the CL160 dropped from more than 10.000 km to a some 100 km. With that, investors pulled out,

Working in the industry I have seen the shipping by train increases pretty steadily as it is cheaper then trucking by a significant amount of time plus in longer distances moves is faster. On down side is that then the shipment needs to be picked up and delivered somehow from the rail yards. A lot of trucking companies have started using this method a lot more then having city drivers in these big ports who pick up and drop off shipments. Just my observation. Though the rail industry is monopolistic in North America with these companies penny pinching and not heavily regulated because of it’s importance to the supply chain. It’s a hard line to balance but if more regulations were put in place for rail companies overall it would definitely be the best method for price and time.

      Rail is the best for overland transport in every way. Ships are best for sea transport. Airships are much faster than maritime ships, but maritime ships can transport higher volumes. Airships are also cheap alternatives to helicopters.
      Like rail, airships can be powered electrically, and unlike trains, they have the surface area for solar cells. (Not necessarily the crystalline ones; the ones that can be painted on are lighter and cheaper, but also less efficient. Still a good trade-off.)
      Maritime ships can be powered by wind, and some are partially wind-powered already. Where propellers are needed, electric motors are best because they provide the most torque, are the most efficient, and require the fewest parts. Unfortunately, container tall ships exist only on paper so far. Airships could fill this gap.

    The problem with the cubed-squared advantage is that the larger the airship gets, the more shearing forces it has to deal with from the atmosphere. A helium balloon is fine with a very thin layer of rubber or mylar, but build a balloon like that on the scale of an airship, and even light gusts of wind will tear it apart. So there's also a cost in going larger, in terms of the support structures necessary to keep the airship in one piece.

    The equilibrium challenge could be solved with modularity. For each unit of cargo offloaded, an equivalent unit of buoyancy is tethered to the cargo station, maintaining equilibrium without loss of potential energy. Tethered ballons would then be added to airships to maintain equilibrium while adding cargo. Logistically nightmarish but potentially very energy efficient. Really what you want to do is map lifting modules one-to-one with cargo destinations, so the module detaches from the mother ship, is tethered to the cargo station, unloaded, then filled with cargo, untethered, and added to an outgoing airship. You definitely want to have modular boyant units and you want the modules to clip together to form larger lifting units. Definitely separate primary thrust providing modules from lifters, that's a no brainer.

      Interesting, but as you mentioned potentially logistically challenging, I wonder if there's a combination of solutions here. Offloading lifting gas, compressing lifting gas, and using ground-based infrastructure to quickly mediate the needs. Perhaps, a large volume gas connection can be made, that pumps large amounts of lifting gas to a ground based tank (or balloons), where it can be efficiently compressed and compressed gas is returned to the airship. Lots of ways to combine.

    What if you made those gas compartments in the rigid airships modular so that the right amount of them can be pulled down at a port (with a kind of inverted crane) at the same time as the loading-off of cargo? Thus as the weight goes down, lift goes down equally.
    These modular gas compartments can be stored at ports for future airships that are departing and need more lift for the additional weight of the cargo.

      Love your idea. That was mine: Would it be possible to take the Helium/Hydrogen out with drones? They come up from the logistic-center and take robust ballons out as the payload of the blimp reduces. On the way up they create lift, when they want to go down, they turn upside down and slowly descend until they can attach the ballons on the ground.

      True, it could make it longer to load and unload but it would be far more economical than replacing it with pull-down weight, and could be a realistic solution considering we cannot compress helium yet.
      If the belly of the airship could be openable, you could add the compartments at the same time as the cargo that would sit beneath.
      I wouldn't think you'd need a heavy and clunky system to attach them considering the compartments would actually be the ones lifting the airship's structure. Also, the core structure of the airship being completely rigid, it wouldn't deform

    Would love to see it happen but unfortunately airships have an achilles heel - weather ! Wind in particular can put them at risk near the ground during takeoffs and landings. Even worse perhaps is that wind in hilly/mountainous areas can be turbulent enough to totally overwhelm An airships manouvring ability. This limitation means that airship activity is highly weather dependent and thus subject to sometimes lengthy delays. Because of this i expect we will see them take on sightseeing tasks but probably not much in the way of freight !

    I might be wrong but i believe compressing at a slower rate the gases needed for lift is possible with a simple (ish) trick that is actually used by ships already, an anchor, basically you take the load to wherever you need to, anchor and then compress the gas at a somewhat slower rate but currently possible, and just un-anchor once you have the lift stable. And in-before comment saying that anchors cant hold that much weight... let me remind you they are used for cargo ships in the ocean which are WAY more heavy

    If the Airship was going to a location that had pre-existing setup you could just have some anchors cemented into the ground that'd be like set-ins when climbing, Airship lowers some durable cables, hook those into the anchors, and then pull the Airship down with winches and keep it stable. Could also help with the wind issue if the cables are kept taught.

      I had the same idea, but it doesn't really solve the problem - it only delays it.
      This would only work if you can replace the cargo with different cargo of the same weight, which makes it incredibly inflexible.
      Otherwise you can unload all cargo but at some point you want to release the cables, and before doing so you have to decrease lift or the airship will be ejected straight into the stratosphere and most likely be destroyed in the process.

You could have airships running back and forth in a continuous loop between two cities, for instance, operating for a long time by being attached to the wire on the ground. If you want to take it off the track for whatever reason you just eject some gas to reduce the buoyancy, but ideally you wouldn't have to do that often. There's obviously a clear danger of the thing shooting into the stratosphere if it gets unclipped, as you said. So you would probably want to make sure these do not have any people on board.

    For the problem of having to reduce buoyancy when unloading, there is a solution that requires specific infrastructure which eliminates the remote area advantage, but could still work in a commercial sense.
    You could set up a network of helium storage wells at and around existing distribution centres and logistics hubs so that when an airship unloads cargo, helium is released via hose pipe into a ground storage well, then be either be pumped back in when the airship is reloaded, or stored for future loads and unloads.
    There would be a need for ground crews to operate and manage the pumps and a "harbour master" of sorts who keeps books and records of transfers, kind of like a helium bank manager

    I wonder if a solution to the buoyancy problem could be to have partitioned balloon sections that can be anchored to the ground when offloading cargo to offset the weight. For example, an airship with several separately filled balloon sections could arrive at a port, anchor to the ground, offload 500 tons of cargo, and then take-off by decoupling from a 500 ton section (or five 100 ton sections, etc) that's already anchored to the ground. These balloon sections could then be reattached to airships that come back to the port and load up more cargo (while anchored to the ground during the transfer of course). I feel like this would be a more economical way of solving the buoyancy issue without the need for compression or having to throw counterweight overboard.
