Hello, /N/. I question pop up in my head a while back and for the life of me, I can't find an appropriate answer. In a post-apocalyptic world, how would private transportation, or Public transportation re-emerge into a city-state society? Also, how would urban planning be like?

I think that hydropower would unironically be a vital part of reconstruction efforts because it doesn't require the same elaborate supply chain as fossil fuels.

I'm exaggerating a bit for shits and giggles, but the fundamentals (society rebuilds using renewable energy resources that are already in place and haven't been destroyed, like dams) seem reasonable to me.

If there's a collapse of global supply chains, but the underlying technical knowhow doesn't change, you'll see some really weird shit.

Or avoid all that and mechanically link them
>>
>>1249097
There is no way to mechanically link the side sticks though, they were never designed for that, and even if Airbus were to do that in a future aircraft, it would introduce serious complications in Airbus philosophy and flight deck design.

Plus, this is one of the most core aspects to multi-pilot flying. Positive transfer of controls are a really core element of flying. If you have that lost, even in a mechanically linked system, you're going to have chaos in the flight deck.

Which airport has the best internal transport system?

Terminal 5 is like that at Heathrow.

That airport has a landside/airside format. It's not the only airport set up that way. The airports in Tampa and Orlando Florida are also set up that way.

It's great in that there is minimal walking required since all of the parking structures and airside concourses are connected to the main terminal by people movers, but the trade off is that you have to go back through security if you have a connecting flight in a different concourse. It's also a pain for less important things. In the Tampa Airport, several great local restaurants have a half-size version in the concourses, and you can't get to them unless you have a boarding pass to a departing airplane in the same concourse.

BTW, If you happen to wind up in Concourse E in Tampa, do the Columbia Cafe, and get the half-and-half with a meatloaf Cuban sandwich and 1905 salad.

This is why I hate concourses that don't have secure connections to each other, at least at big airports. I want the option to go to lounges and restaurants in other parts of the airport without having to come back through security.

My home airport (SFO) is in the long process of connecting all of the concourses in the airport to each other with secure connectors. T2 and T1C already have this, as do T3 and International G. T1B has secure connectors under construction to T1C/T2 and to International A. T2/T3 and International A to G connectors are in planning. Even without the A to G connector, which will come last, you will be able to get between every concourse securely (albeit not as quickly without the A to G connector).

To be fair though, you can enter any security checkpoint with a current day boarding pass, regardless of airline. So technically you can get everywhere already, but not easily or very practically. CLEAR and TSA Precheck make i all much less of a pain in the ass though.

Hello /n/, /fit/ told me you would be more suited to answering my question:
I am planning on purchasing one of these for my bicycle so I can keep getting cardio inside during the winter. Does anyone have any experience with these things?

I'm thinking of getting https://www.amazon.ca/AccelaVelo-Fluid-X-Indoor-Magnetic-Trainer/dp/B011AD2FIU/ because it is within my price range.

373s don't have the high voltage running along the roof line, since 1. british safety rules don't allow it, 2. limited height would be tricky, 3. there's no way to have an electrical connector that could safely disconnect 25kV just by pulling apart when separating the half sets.

Regarding pantograph/overhead oscillation, it's not a huge deal for something like the 373 or an ICE 1 (which also doesn't have the high voltage line on top) since they're so long, pantograph to pantograph distance with both up is about the same as two TGV sets coupled together, longer than a pair of ICE 2 facing same direction or ICE 3 sets which are also acceptable configurations.

Looking at old videos they did run both pantographs up on UK north of London, with both power cars running https://www.youtube.com/watch?v=YJI9KWktI2k, I suspect the power limit was just from substation capacity, not the train.

As part of a project I hope to design a bicycle with a friction drive mechanism. The system needs to be powered by pedal rather than a motor, any suggestions or ideas about how i could approach this.

The general idea behind this is for quick rear wheel removal, allowing the user to lock both wheels to the frame using a U lock

Unless you had a multi-stage gearing system in between the cranks and the rear wheel, this would give you an unrideably low gear
>>
>>1248932
That is not a friction drive.

>>1248927
For a friction drive (which is a horrible way to power a rear wheel) you'd have to have a roller press down on the rear tire and drive the roller via a chain.

If you want friction only, put pedals on the roller and design a bike around it.
>>
>>1248927
Why not just remove the front wheel?
>>
>>1248962
Those CTV hubs are technically friction drives
>>
>>1248927
Use a v-belt. They are less efficient then chain drive, but are still quite efficient.

When I occasionally use the train, I buy two tickets for myself so I don't have to sit next to anyone due to my social anixety. Here the trains normally have two seats next to each other and are quite tightly packed so the additional comfort is appreciated.

Yet by the time the train starts getting busy there's always someone who insists I move over or move my bag. I tell them I have paid for two tickets; therefore have taken these two seats and that they must stand. Women always get pissed off by this and sometimes make a scene.

Who is in the wrong here? I've paid for two tickets, so technically can take two standard seats when available. One for me, one for my bag. I never sit in disabled areas so that's not the issue.

Anon, the trick here is to gain so much weight that you take up two seats naturally. That way, when a pregnant or elderly lady asks you to give up your seat(s), you respond that you're literally too fat to move. Problem solved!

Work on your anxiety, it will save you money in the long run. Also as a tip, on trains with 3 seats in a row, if you sit on the outside seat many people will hesitate to ask to get in your row, especially if it's only the middle seat left.
