Has anyone thought about using one of these scaled-up for large diesel engines?Having these allows for keeping air/fuel ratio optimal (λ = 1) through a larger range of power outputs and increases efficiency by allowing for the extraction of more energy from the exhaust gases. For instance, a diesel locomotive could use one to boost power to its motors or for head-end power. LNG carriers could use the energy generated to refrigerate the cargo.I understand it'll be complex and difficult to implement but the potential is huge.
>>2015259>having the turbine driving a generator/alternator and acting as a pseudo-APUEmma-Maearsk class container vessels use the APU solution - a second turbine behind the turbocharger drives a generator. Additionally, there's a two-stage steam generator with superheating behind that to use the exhaust heat in a steam turbine also running a generator.The electricity can power onboard systems, refridgerated containers or (through two 9MW motors on the propeller shaft) be coupled back into the driveshaft.It's a very interesting system from an engineering point of view.There's 30MW of diesel generators on those things that don't normally drive the ship, plus a 82MW main engine. The electric motors allow a total of 100MW on the shaft, or for the main engine to run the electric load too. Pretty unusual for large ships but allows load-point shifting at low speeds (huge efficiency boost at high development cost)Exhaust is gathered from all engines for the heat recovery system and can bypass the turbos as appliccable.The steam turbines can make 8.5MW, the exhaust turbine another 1.38Brake thermal efficiency reaches 55% like thatAll numbers according to wikipedia.

This thread is for talking about railways, and things related to railways, in the United Kingdom of Great Britain and Northern Ireland - that means we're all about big intercity trains, modest rural trains, long freight trains, trips, tracks, (deep breath) trams, subways, stations, and a partridge in a pear tree~.If you're unfamiliar with train travel, take a look at National Rail's journey planner, at nationalrail.co.uk/ - tell it where you're travelling from and to, and it'll show you a few options before handing you over to a train company so you can buy a ticket. For the same journey, they'll all charge the same price, so it doesn't matter who you buy one from. The best option for overseas visitors would be to use thetrainline.com/ - it'll support your language and payment card.Here's a few links:~The Man in Seat 61 (seat61.com/) - easily the best rail travel resource out there.~A Visual History of Railway Rolling Stock in Great Britain (gaelan.me/br-stock/)~Geoff Marshall (youtube.com/@geofftech2) - likes trains.

I would rather drive down to London from the the Midlands than get on a train again. If it's more than 2 people in the car it's actually cheaper too.
Someone I work with was talking about rail strikes again, and I had to explain how there are two different unions, one for people who work on the tracks and one for train drivers. But it made me think: if train drivers are going on strike, and if the train companies are privatised, what do we care if they get paid more? It's a private company; my taxes don't pay train drivers. Do they?
>>2018551>my taxes don't pay train drivers. Do they?They don't. The closest you'll get to that kind of thing would be how Network Rail - the 'everything that doesn't move or breathe' people - currently exist in a legal fiction where they're an independent private company but just so happen to be underwritten by the Government so that they can borrow money from banks at favourable-ish rates. Like a 16-year-old being put on their dad's car insurance.
vaguely interesting: there's track drainage work going on around Berwick this month, so for a few weekends it's Azumas up part of the WCML after doing a loop-de-loop in Newcastle.(a rare thing since privatisation - one of those shitty 'it's cheaper + less faff for us to put on rail replacement buses than it is to have drivers maintain route knowledge outside their normal patch' things)
How do the Japaneee get away with branding their folding bikes with car brands?Anyone here tried these folding bikes?

>>2015104>How do the Japaneee get away with branding their folding bikes with car brands?>Anyone here tried these folding bikes?I bought a 2001 Jeep Liberty when it came out and they gave me a full susp Y frame bike with it. It was awesome but so heavy (I didn't know better). Even being heavy it was a city park princess- essentially a great replacement for a cruiser but not sturdy enough to ride an MTB park. Triple in the front. Y shaped frame, coil spring back susp.I chained it to an iron fence and left for the weekend and when I came back it was stolen.Used it for 5 years and got probably 2500 good miles out of it riding around town.
Anyone work for Lime/Bird/Whoever? Any numbers that these share programs are a success? They had them in my distance suburb satellite, and lasted maybe a year. I used a bike share one way on Chicago after taking the train from Milwaukee. Anyone else love the grossness of handles and seats you can't imagine the filth of? How many units have you seen on their sides/not at docks/in canals. Are the another scam/handout band aid on the cancer of car dependency?
I excepted share bikes to be a specialized scam of course, but this is the 40,000 dollar pentagon hammer all over again.
heres a very work in progress pic of my 3x13 39speedi couldnt see any reason why a 13s wouldnt fit my 9s hub and it seems to so far lol, wit a spacer toodesu im probably gonna convert it to a 2x11 at some point to save weight this is just for funsiesim also running a 12s chain because 13s are silly expensivewhat are the chances this fails epically?
>>2017605I don't think it's worth doing on a bike that isn't cool and kinda fancy, like OP.
>>2017608You are probably right and it would probably end up costing more than I'd be willing to spend... and then the mixing and matching of parts... and just finding and assembling, and then maybe fabricating to make it fit to a frame it was never intended for would take too much time.
>>2017610>fabricating to make it fit to a frame it was never intended for>would take too much time.those are both nonsense reasons, wtf would you have to 'fabricate'? Bicycles ARE intended for such things. >i want a silly meme project but i'm lazy why even bring it up lol
>>2017611bro I was just inspired for a minute or 2 lolseriously it would be fun if I had a ton of spare parts at my disposal, but I don't
What is the intent behind statements like "I'm not a cyclist, I'm just a person who gets around by bike"?At a surface level it is obviously meant to (proverbially) throw other cyclists under the bus, but to what end? Would it somehow appease the anti-bike people if the person "blocking traffic" didn't agree to be referred to by the word "cyclist"?
>>2001345Here is some context from a Dutchfag, a large amount of Dutch people live in relatively small towns and commute into the Randstad (Most urbanised area of the country) for work. It is not realistic to bike from outside of the Randstad into it. However, if you actually live in the Randstad, and work in the city you live in most people then choose to bike. Getting around the place you live though? It's cycling all the way. I almost never leave the house without my bicycle whether it's going to friends, to the store, or just to the nearest city. TLDR; Commuting by bike largely isn't possible for most of the population not living and working in the city they live in. Also, public transport is more expensive compared to automobiles.

I am looking for a youtube channel of a guy or group of guys putting heavy mileage on ebikes.Maybe food deleivery ?What I am looking to learn is about how well these hold up under heavy use and what mainanace issues there might be long term.I live out in the boonies and need to commute 22 miles each way every day so the miles are really going to add up
>>2017947EbikeSchool and Electrek, both channels with Micah Toll, are good spots to begin. In general, hub motors will need to be checked for gear tooth wear and kept lubed, mid-drive motors will require more chain/cassette maintenance and swapping due to wear. Some kind of tire liners/flat protection is helpful, too, I use Mr. Tuffy liners for my cargo bike, if you live in a place with lots of broken glass/goathead stickers, Tannus armour inserts might be necessary.https://www.youtube.com/watch?v=ckeFFTffQZc

So basically there is never going to be any real investigation to find out what happened? We are just gonna swallow "Oh LOL crew accidently left doors open! Scusi! LOL" or some other bullshit while they killed this dude with some collateral damage.

>>2014576How is it superior to front paniers?
From old to new, big to small, I have almost never heard of;>Planned Obsolescence>Vendor Lockout>Poorly Speced Components> Quality Control Problems>Price Gouging>Lack of Parts Availability(Even on equipment from the 70s)>Dealerships being so much as impolite to customers (even if they are only buying one part for a 50 year old machine)Comparing similarly sized machines with skid steers, its night and day. In the general world of heavy equipment, everything is whittled down into something that just barely lasts through the warranty period, except for some reason forklifts. Why can I buy a forklift that is so damn well thought out, reasonably priced and dependable, but not a skid steer, dozer, washing machine, car or truck?
>>2015529Forklifts don't and can't have any safe failure modes.
>>2015529Forklifts come with service plans that are factored into the cost of buying a fleet of them, right alongside liability contracts for avoiding downtime. And and in order to keep that cost down, they need to be dead simple and reliable. Not just because the repair and maintenance needs to be cheap, but because if downed equipment impacts a customers profits, the company selling the lifts will be sued into the ground shortly after, and subsequently have their reputation tanked.I work for DHL, we buy Crown forklifts. They’re simple machines, propane 4 cylinders at their core which require little maintenance and can be abused horrendously without batting an eye.If they had say, some flawed component that caused 3/4 of the fleet to fail one day, that would cut our ability to move freight so heavily that it may shut down a customer.And in that scenario time becomes money very fast, like $10,000 a minute fast on the low end. If that shutdown is deemed to have been the fault of the equipment provider? They will pass that bill down until it’s Crowns problem.So crown brings us solid equipment, because they can’t afford to do any nonsense since the outcome for product failure isn’t like how the automotive industry handles it. If the Corolla sucks for some reason one year, big deal, there’s some recalls and people don’t like the Corolla name for a while.If a certain range of forklifts causes a loss of time, no customer will ever buy those forklifts, and they will avoid your entire company, and encourage others to not buy your forklifts.
>>2015529They are inherently valuable, unlike a consumer automobile (worst "investment" everyone in common life makes).And the eternal pressure of other business men not buying a liability of a dog piece of equipment, unlike the eternal sucker or the citizen consumer...But to be fair, forklifts are hothouse darlings of hyper primitive suite of simple machines in a supremely prepared use area. I worked in material handling corp, and they had a onsite museum as they sold forklifts. Shop too. I used to have to drive by hundred of these things off trucks. And every other kind of lift/electric floor jacks too. Loved that job but it was a career dead end.
