>Can't build plane
>Can't build engines either
P&W GTF series has problems across the board, and it's not a problem isolated to Airbus. A big part of the reason Bombardier had to unload CSeries was the delays and technical problems caused by the P&W GTF, which was CSeries' sole source engine. Embraer E2 is also having problems with P&W GTF. Mitsubishi's termination of the SpaceJet program was also at least partially attributable to the P&W GTF.

SE bikes are pretty much only operated by juvenile delinquents in those summertime "flash mobs" that ride around crashing into people and generally being obnoxious in groups too large for the police to try to do anything about. They're also almost all nonwhites too.

I'm not saying you shouldn't like them but it's kinda surreal seeing /n/ nut over this thing when you guys are hostile to anything counterculture-ish, unabashedly racist, and generally not in favor of anything that isn't pushed by the mainstream instagram algorithm towards the 25-35 year old white male incel demographic

Do you still have a PS2?
I think the backwards compatibility doesn’t go that far.
embarrassingly I never thought about racks for some reason.
Still got the PS2 but it's terrible on modern TVs. Emulation is pretty good now so it sits on my desk like a tiered table until I can give it away to someone who will give it love.

if the rail company is smart they're invested in the cheap property and going to develop it. this is what the Japanese rail companies did. they bought whatever was the cheapest land they could connect to the nearest city. then they built the line. then they built housing on all the cheap land along the line. all the men would ride twice a day to work and back. two fares per day per household. THEN they built a park with rides and shit at the terminus of the line, so then the wives would go there with the kids. that's one adult and however many children's fares there and back each time. then they paid admission to the park. they got rich.
I have no confidence any American rail company is smart enough to do this, but that's a proven way to make money and give your clients a better quality of life, so I'm sure they won't because who cares about the poors that ride the train lol
>I have no confidence any American rail company is smart enough to do this
They're government entities not companies and the government isn't interested in speculative real estate when they already have 100% guaranteed revenue
But he's right. Transit advocates like yourself unironically believe that most people in major cities travel an hour in each direction every day. I'm not sure why this is the case, either accidentally doubling one-way commute times, or deliberately lying. You can look at some maps here, and there are other sources that in most American metros, commute times are not nearly as long as it's pretended to be.

and you faggots act like transit takes forever when you've just proven that it's usually only a 10-20 minute time penalty

I think one of the big issues was re-engining. It used the same 1960s-era afterburning turbojets it did back when it was first designed. However, there wasn't any newer engine available that could do the job. So it was eventually decided to pull the plug on support.
Considering that Olympus593 was developed in the 60's, 50 years of advances in metallurgical technology could improve the fuel efficiency of the engine by about 20%
Concorde was economically inefficient because it was built in the 1960's. An old airframe with inefficient engines that guzzled fuel.

A newer design can be more efficient; in fact the Concorde B was always planned to be built which would have had a more efficient wing profile and engines (no afterburners) and used much less fuel, but it obviously never got built because nobody bought the original.
>only 20%
They already knew how to increase efficiency in the 593 by 25% back in the 70's. They just never built them because nobody needed them.

a-and i VILL be happy right?
even during concorde was only meant for rich people, the tech will become more affordable with time as with everything else

No, this is the rationalization you tell yourself for why you don't do it. The real reason you don't do it is survival instinct. When it comes right down to the line, you don't actually want to die.
Take steps toward improving your life. Work up the courage live life, rather than working up the courage to end it.

It's an interactive map to show the best places for transportation and walkability.

The default is Grocery + Library which makes the map really really narrowly defined and there's no real way to weight the options, so I recommend disabling Library and/or using just one at a time. But it does an incredible job of highlighting walkability and would make a great tool for deciding where to develop or move

The far left hates cars. They want to get rid of the word private. Cars? Use the bus. Housing? Here’s a pod sized room with shared facilities. All in the name of efficiency and “fairness”. They want us living packed up like bees in a hive, a totally unnatural and unhealthy way to live. A reasonable man would conclude that a mix of sense urban accommodation and less sense housing on the outskirts is the way forward but these chumps only think in terms of surviving on what you “need” only, which funnily enough drives up profits for developers who can make far more money off sell/rent larger numbers of smaller apartments for far more than they can ever hope to get from larger family sized offerings. It’s an utter charade.

>Actually a couple months ago I did some airflow simulations, the result was that my design is shit.
Pic related. I went with forward slanted windshield. Also on the side the top is slanted outwards. To protect against the sun. At the front the window is bigger for better visibility.
Enclosed wheels. The whole velo is quite high, because the hottest air is always at the top and there is also where the head is, so I tried to give more headroom. But extra height is not good for aerodynamics. Forward slanted window also not good. Mainly I think, because of high sides, so the air doesn't have anywhere to go. But I need these high sides because of the riders shoulders and also the wheels.
I was also trying with different angles at the back (kammback style). For my surprise the sharp transition from main body to the angle gave better results than smooth (fillet) one.
Aerodynamics is though.
Design issues I see right off the bat.

>Large profile: will act as a sail in crosswinds
>Large windows: adds a lot of weight if using a hard material or very scratch prone if using something lighter and weaker. Will need to be replaced, which will be expensive and a PITA.
> Condensation: the thermal difference between inside and outside will condensate the air on the window. Unless you have some kind of holes or fan that blows air into it.

Current commercial velos (Bulk, snoek, and the likes) the the way they are because of a reason, and your velo defies all of that. If you go for style rather than efficient you'd still have to solve the issues I greentexted. Wishing you good luck.

What software is that btw?
>Large profile: will act as a sail in crosswinds
Some say that can help go faster, sailing like a sail boat. I assume it might work in steady winds, but in sharp abrupt winds seems to be more trouble.
Otherwise I agree with all you said. That all was my concern, but I was playing around with forward slanted window design and I ended with this shape. if it would prove to be good aerodynamically, I might compromise on other stuff, but it is not.
Also it's impossible to see any traffic lights, because you can't see above eyelevel.
That is why I have abandoned that design. It is no good on any aspect. I thought of it, I tried it. In a trash it goes.
Next one will be more slim and compact. And small window. I still want to make it forward slanted though.
I've got some new ideas, I'll see how it goes.
Software is solidworks.
