content: So I was alerted to this Pipedream thing in Twitter, and have been having a back and forth with the CEO.I didn't even need to look at the website or any other info to know this is literally and ironically a pipedream.Package delivery by 12" pipes.https://twitter.com/eevblog/status/1516598333804265473https://i.pipedreamlabs.co/I think it earns it's own thread in the Dodgy Technology section.I thought about doing a video, but is it worth my time?

content: Doable, and I remember the pneumatic systems still being in use when I was young, in at least one bank and one department store. But long gone, just too high maintenance, and killed off by the computer making handling cash redundant, and no more hand written receipts. Using to move small items, that will fit in the canister, from one location in a factory, to another location, in the same building, it will work and be efficient, kind of like the semiconductor industry needing to move wafers around, though there they long ago standardised on a rail system, that also can provide power and communications to the transports.Very niche otherwise, only used if you need parts fast, but the end points are far apart, and simply using a trolley is going to be difficult. Biggest user used to be the postal service, to move mail around, but that is long gone now, the mail moves along a series of tubes still, just they are made from copper and plastic, or glass.

content: Actually, it's nothing new:https://en.wikipedia.org/wiki/Rohrpost_in_BerlinAlso found in other cities around the world.However, as a short message system, this has been made redundant by the teletype, telex and the internet.This new pipe dream is a nightmare. The shown pod is *way* too complicated (the former pods, called "bombs" in German, were a simple tube with two rubber ends - unbreakable and cheap). Even more absurd is the "portal". Those would be damaged forever after let's say 15 minutes. That's how long it takes, before the first trash is thrown into the portal opening.And I'm not sure how they would be able to install their system in e.g. New York. To my knowledge, the underground is a complete mess of undocumented piping and cabling.

content: Up to 75 MPH sounds unrealistically fast for a small battery powered unit, when mis-aligned or jammed, may smash up the pipes, which will be tricky/expensive to repair, if buried underground. Also, surely the plastic pipes, would soon be scratched and wear out, if things at up to 75 MPH were regularly going up and down it. So, the pipes would then have to be regularly replaced, which because they are underground, would tend to be very expensive and time consuming.Batteries would tend to wear out after around 500 to 2,000 uses, and could be expensive to replaceBig piles of parcels (which delivery vans can be filled to the brim with), would take ages, to carefully load into the carriers, then patiently feed into those (slow by the sound of it), street chutes.If the underground infrastructure needs electronics, such as sensors, computers, power, control, security etc. It would need regular maintenance and repair. Which would be tricky, very expensive and time consuming if underground.How exactly would the inevitable regular, underground jams be sorted out ? If it involves digging up the street, a significant workforce and would take a couple of days to sort out, per jam. It could cost a fortune, and might occur, at least once every 1,000 journeys (wild estimate).I.e. Look at a typical, giant (parcel) warehouse, which is NOT underground, or difficult to reach the conveyor belts. I suspect they have/need teams of workers, to almost continually un-jam the parcels and/or fix sensors/adjustments/motors/belts/etc all too regularly.TL;DRI don't think the proposed $0.75 per parcel/journey, is realistic.

content: Uh yeah, pneumatic stuff is old tech and long abandoned. Beyond the cost of infrastructure, just think about what could happen in case of failure.For the fun fact, such a system was mentioned in "1984" - as if we weren't rushing towards a 1984-like world fast enough already.

The previous system was packing them in boxes marked urgent/non-urgent and then every half hour a taxi would pick them up

content: As late as maybe 20 years ago, short transport tubes were common between car-parking stations and the bank in drive-in banking facilities.In my youth (oh so long ago), department stores often had only pneumatic tubes between points-of-sale and a central cashier station, where the salesperson sent an invoice and the customer's cash to the cashier, who returned a sales receipt and the change.Many years later, I was just chatting with fellow employees over lunch and mentioned that I was starting to play with vacuum tubes again. I was surprised when a lady accountant said that she used to have them at her previous employer, but then found that she meant pneumatic tubes, not pentodes.The Paris system ("pneumatique") was finally shut down in 1984. "Pneus" were often billets-doux.

For home delivery I can't see it, due to obvious reasons (digging up public streets). I don't really think its worth debunking unless there is another element here.I guess one question is which is a better system for these locations where it does make sense, fully pneumatic or electric motor based?

But there could still be all sorts of other real life issues/problems/drawbacks, with the proposed ideas.Quote from: thm_w on April 20, 2022, 08:38:43 pmGood point. Pneumatic, seems to have been chosen, in many previous solutions, over a number of previous decades. But that doesn't mean that Electric motor based, is ruled out in the future.

content: Quote from: TimFox on April 20, 2022, 10:23:11 pmThat's amazing!I don't think I knew about that system. 300 miles of tubing, sounds like quite a lot.It seems one of its points (disadvantages), was the cost of all the labor, to keep it working. But these days, most/many of the staff, could be replaced by automatic robots. So I suppose it could come back in fashion.It would be great to order something on the internet, then 5 minutes later, there is a big whooshing noise at home, as the parcel(s) arrive. Without even needing to answer a door, or go to a collection point or similar, which could be a number of miles, from home.Some people think, one day. We could all have 3d printers, which can then make whatever we just ordered, such as dishwashers, new computers, TVs, etc. I.e. instead of just melting plastic filament wire/cable, it could manipulate other materials, such as metals. To make, just about anything. Perhaps with FPGAs/MCUs, programmable/configurable analogue devices, to make the electronics for the product.

content: Quote from: EEVblog on April 20, 2022, 10:44:09 pmI agree, it is unlikely to happen. Especially not anytime soon, because it would cost way too much, take too long to develop, and doesn't really offer that much of an improvement, compared to existing solutions.If a parcel is small enough (i.e. letter box sized, in the UK), typically it can be delivered by the standard postal services, of the applicable countries. In a reasonably timely and reliable way, at a somewhat fair cost.When/if self driving vehicles, becomes a thing. I suppose they could invent/create self driving delivery vans, which simply put your items, into a deposit box, outside where people live. Using a robot thing, between the van and the persons home.Then little infrastructure would be needed. It would simply be a potentially cheaper and faster solution, to the existing parcel delivery services, we have today.

content: Quote from: thm_w on April 20, 2022, 11:04:24 pmIt would seem to cost a huge amount of money to develop, and implement. Without really offering much in the way ofunique selling points, to justify throwing out the existing delivery systems, and paying for a replacement system.Quote from: thm_w on April 20, 2022, 11:04:24 pmThat's better. But still would cost a fortune, take ages to complete, and suffer from all sorts of drawbacks and disadvantages.Quote from: thm_w on April 20, 2022, 11:04:24 pmI don't think it would have much impact, on how much traffic there is, overall. Because there are so many journeys, for so many different reasons. Also, it would still involve a lot of traffic, until it reaches the final delivery hub, street carrier chute position(s).Quote from: thm_w on April 20, 2022, 11:04:24 pmAmazon lockers, has the same issue. They are an option, for relatively small items. But can't accept bigger items. Which means that conventional deliveries, are still needed, for a number of (bigger, heavier, or more problematic) items.

content: Quote from: EEVblog on April 20, 2022, 11:50:54 pmIf he invented something, which was genuinely new and doesn't already exist. Perhaps a robot, which fully maintains someones garden(s), for them. Keeping any grass, trees and shrubs, looking nice and healthy. Some people would come flocking to his door, and say take my money.But this idea, offers little benefit to the existing solutions, would probably cost an impracticably huge amount of money to create and involve lots of work and hassle.He seems to think deliveries could realistically take place, within 10 minutes from making an order. But, a realistic, county wide (region), delivery chutes system. Would still probably take quite a while, to actually deliver stuff to people. Because it would have to deal with thousands of parcels/deliveries, occurring in real time. Which would mean significant queues and hence delays.E.g. Supper/Dinner time on a Friday night. Many want their (fast) food delivered. So, suddenly, around 5 to 10 PM, there would be thousands and thousands, of similar such orders. They can't all be handled simultaneously, with the same infrastructure. Also, food gets cold. So, delays wouldn't necessarily be acceptable.People want deliveries to be as cheap as possible, which is why delivery companies, tend to be low profit organisations. A low profit market, is not ideally suited, to attempting to get that market to pay huge installation costs, for a radically new set of solutions. Which seem to offer little real benefit, except in the inventors minds eye. Which is what you basically said, in an earlier post.

How does maintenance work? And I sure hope they have a back-up solution, probably involving classic delivery.

When Mercury Communications started in the UK in the 1980s, it was feasible for them to start wiring up the City of London quickly with fibre, because they bought the remnants of the London Hydraulic Power Company. They still owned a series a pipes that was put under the city in Victorian times, to hydraulically power a variety of systems before the electric grid got started. Their pipe network was ideal for quickly deploying modern telecoms.

content: Similarly, there was an underground freight-tunnel 24"-gauge rail system in Chicago, which is still in place although service was ended in 1959 after the two CTA subway tunnels on State and Dearborn Streets severed much of the dense matrix of tunnels 40 feet below grade. The network reached 60 miles, all under Chicago streets that (mostly) form a rectangular grid. The remaining tunnels in central Chicago were fixed up by adding flood gates after the infamous underground flood of 1991-92. The tunnels are in use by the electrical utility and various communications cables.The company that drove the pilings in the wrong location to pierce the tunnel roof at Kinzie St claimed they didn't know the tunnel was there--if they had asked me, I could have shown them the map in the standard book on the subject.Later, in 2004, the Kinzie St bridge (which the pilings were supposed to protect) was the site of the infamous Dave Matthews Band incident (q.v.).

content: The narrow-gauge Chicago freight tunnels were dug on the cheap by digging up the public roadway, fabricating the relatively small tunnel forty feet down, then covering it again ("cut and cover").Later, two subway tubes were added downtown, to normal loading gauge and standard rail gauge. Almost all of the subway tunnels were bored with a boring machine.

Now those cities have mushroomed in size they are finding further infrastructure much more expensive to build. Even if some of their earlier work was not of the highest quality, its a lot easier to upgrade it than to put new systems in place in a busy city.
