Not looking forward to sidewalks and curbs covered in a tangle of car charger cables.

Nusm ,

A tangle of cables? I’ll feel right at home! …and right at work! 🤣

partial_accumen ,

Tesla is developing a wireless charger. So these could be embedded in the street negating the need for cords.

SpaceMan9000 ,

Ah yes, just fuck up streets and waste a fuckton of energy due to wireless charging

AA5B ,

While I agree with the drawbacks of wireless charging, it could prevent cables obstructing pedestrians and prevent vandalism. Maybe it’s a good idea for street parking

partial_accumen ,

I am assuming you’re assuming inefficiencies in wireless charging over wired charging. One provider looking at this technology finds wired and wireless VERY close to one another in efficiency, with wireless possibly being even MORE efficient.

"Wireless charging for EVs is considered as efficient and fast as charging with a plug. For example, most EV plugs have 80-95 percent efficiency ratings. According to WiTricity, a leading provider, their wireless EV chargers achieve 90-93 percent efficiency. " source

I would be interested in that if done by anyone else than elon. I wouldn’t put it past them to have made that proposal to kill public transit or something else. Like they already did with the dumb tunnel that was canceled now.

TheGrandNagus ,

Yeah, and most wired charging for a modern EV and charger is on the upper end of that scale.

The wireless charging being that efficient is reliant on the ground never being dirty or wet, the charging coils on the car being very low, and the car being perfectly aligned.

It would be nice if more manufacturers would put multiple charge ports on cars. Most only have one. And I don’t think anyone is doing more than 2.

Having one on each corner would be dope and would reduce the length of cord that often needs to be run.

Hule ,

I instantly saw a car parked sideways and charging on both ends…

I have a dirty mind.

That’s because all cars can park facing in any direction. Now drivers, that’s another story…

If shopping carts are any indication Europeans will simply plug cables back into the chargers while Americans will be dropping them on the sidewalk and hiring people to organize them.

DirigibleProtein , to technology in Where will all the electric cars be charged?

Do we have to read them their Miranda rights each time they are charged?

autotldr Bot , to technology in Where will all the electric cars be charged?

This is the best summary I could come up with:


A big advantage of repurposing existing lampposts is that cities don’t have to dig in order to lay new cables, says Artis Markots, the chief executive of the Latvian start-up SimpleCharge, which is focusing on Central and Eastern Europe.

Trojan Energy is a Scottish company whose chargers sit flush with the pavement, resembling miniature manhole covers from the outside.

The UK company Nyobolt recently created Bolt-ee, a compact, ultra-rapid charger that can provide up to 300kW of DC power to charge a car within minutes.

Fully mobile charging could be useful for people with disabilities, says Liana Cipcigan, a professor of transport electrification and smart grids at Cardiff University’s School of Engineering.

In terms of fire risks, Mr Shivareddy says that Nyobolt has carefully designed Bolt-ee to be ultra-efficient, and thus to generate very little waste heat.

As Prof Cipcigan says, there is much space for innovation in the EV charging market, and younger and smaller companies “could make an interesting impact on this very complex landscape”.

It will be interesting to know if the cables for these things can handle the load. On an individual level probable, but on larger scale?

lnxtx ,
@lnxtx@feddit.nl avatar

If we change all street lighting to the LEDs, it will save about 200-250 W per pole. That’s peanuts for the thirsty EVs.

Why not fast charge at the existing petrol stations? I know! Convenience.

Fogle ,

Putting fast chargers at the gas stations going across empty highways is huge for ev travel

scops ,

On a hot day sitting in a parking lot, my Model 3 loses about 10% of its charge just cooling the battery. I am lucky to have the ability to charge at home so I don’t have to worry about it, but if I was living in an apartment, I’d have constant anxiety about it discharging and not being ready when I need it. It’s doable, but having to plan out an extra 20-30 minutes plus travel time to hit a charger, that’s a fairly significant change to routine.

That said, yes, more EV charging at gas stations please. It’s critical for road trips.

Better you’re on the airline where they found the problems than the airline that didn’t.

andmonad , to worldnews in Boeing 737 Max 9: United Airlines finds loose bolts during inspections

So are they just going to tighten them up real well and call it a day? Also are these the same planes they were urging the FAA to let them flight without further inspection?

WetBeardHairs , to worldnews in Boeing 737 Max 9: United Airlines finds loose bolts during inspections

After looking at that diagram I have to ask - why in the everliving fuck would a pressure bearing panel like that be hung by bolts and not inserted into the cabin and held in place by the ribs of the fuselage? I mean seriously?

EeeDawg101 ,

I don’t get why they don’t just make it a bit bigger on the inside so that when pressurized, the pressure itself seals it. Seems like a fail safe solution instead of this shadiness.

MigratingApe ,

But mah profits!

737 Max is still a developing example of what happens when you leave corporate to self-regulate themselves.

Tangentism ,

It’s a well documented that when Boeing merged with McDonald Douglas, they turned from an engineering led company to an executive led one & have been shit since

archive.is/vy5p7

Starfighter , (edited )

It is, kind of. The plug is secured by 6 stops (or tabs) along each side. The positive pressure differential pushes the plug outwards into those stops.

To remove the plug you uninstall 4 bolts which allow the plug to go up and over the stops, after which it can hinge outwards on a hinge found at the bottom of the plug.

Source: https://youtu.be/WhfK9jlZK1o?si=dbUV1i2nNFcNixQh

EeeDawg101 ,

Just seems like a better design would be if no bolts existed (like from them loosening over time and falling off), it would still be sealed perfectly fine. The obvious failure point is the bolts and seems they could do better.

AMDIsOurLord ,

I think it’s to save space. See: DC-10 Cargo Door fiasco

derf82 ,

It does. It is still a plug-type door. It pushes against 12 stop pads. This design has been used for many years, including on the 737-900 that predated the Max9. You can see the exit plug in this photo form 2007, before the Max was even a thing. Also, cargo doors have worked the same way for many more years than that.

They do it so that the door does not have to swing the whole way inside to fit out.

cobra89 ,

That’s how the normal doors work because they aren’t permanently secured in place. The reason is weight as it pretty much always is in aviation design.

GombeenSysadmin ,

It’s a door plug, which means it’s meant to be replaced with an actual door if required, so a lot of the hardware for an actual door are in place. Doors are designed to slide in, then raise up so the stop pins engage the stop fittings from the inside, so the door is in effect bigger than the hole it’s in. this video provides a detailed explanation of how it works.

The big issue here is that the airplane is only 2 months old, it was delivered from Boeing in late October. Which means it’s either a design flaw or a process flaw in the original manufacturing. This smacks of corporate cost cutting again. Boeing are totally on the hook for this and it’s only lucky there were no lives lost. You watch, they’ll blame it on the airline initially but the fault will come back round to them again.

Aurix , to worldnews in Boeing 737 Max 9: United Airlines finds loose bolts during inspections

I am glad to read all these reports, investigations and of course the emotional laden criticisms of actors associated with this. Because each time I check aviation incidents in Russia, they determine in the first 24 hours it must have been the pilots fault.

mynamesnotrick , to worldnews in Boeing 737 Max 9: United Airlines finds loose bolts during inspections

MAX must stand for “MAX Profits” because they sure cut lots of corners on that aircraft.

LordOfTheChia ,

More like unexpected new features, like the all new spontaneous exit row!

bajabound ,

Just think how much easier it will be to get extra leg room now.

nova_ad_vitum ,

I wonder how many cents they saved by not ensuring the bolts were properly tightened.

Bytemeister ,

Probably more than you think. This strikes me as an understaffing issue in the factory. Loose bolts happen when the person who is supposed to verify the work has been done correctly, is busy doing work elsewhere on the plane. Understaffing causes people to pitch-in to make deadlines, or to ease the burden on their co-workers. Seems trivial at first, but with airplanes, this behavior gets people killed.

derf82 , to worldnews in Boeing 737 Max 9: United Airlines finds loose bolts during inspections

Picture of one of the aircraft’s bolts: x.com/byerussell/status/1744460136855294106?s=46

Not clear if this is the cause of the Alaska accident. Those bolts hold on the hinges at the bottom, and the photos appear to show those hinges still attached on the incident aircraft.

toiletobserver , to worldnews in Boeing 737 Max 9: United Airlines finds loose bolts during inspections
Zorque ,

Well, as long as it's not in the environment, at least.

conciselyverbose , (edited ) to worldnews in Boeing 737 Max 9: United Airlines finds loose bolts during inspections

The US National Transportation Safety Board (NTSB), which is leading an investigation into the incident, said pilots had reported pressurisation warning lights on three previous flights made by the specific Alaska Airlines Max 9 involved in the incident.

As bad as it is if a manufacturing issue caused a piece to fall off an airplane, there's a huge amount of negligence in an airline continuing to fly an airplane that has triggered pressure warnings multiple times without investigating and resolving the issue.

JillyB ,

Agreed. This is a multi-layered fuckup. The manufacturer probably didn’t tighten things down all the way, their QA didn’t catch the critical defect, the plane inspectors didn’t catch it during inspection, the airline didn’t ground it after a pressurization warning, the pilot flew a plane with a known issue. There are several cultures of complacency at play. Hopefully the FAA can scare everyone into flying right.

conciselyverbose , (edited )

The reason I added the "if" is because I didn't see any information about age and don't know the specifics of the engineering/specs. Bolts needing the be checked annually and tightened every 5 on average could be perfectly reasonable with how much stress is on airplanes. There's a reason frequent inspection is enforced more heavily on airplanes, and it's not just because failures mean potentially falling out of the sky.

But yeah, it's entirely possible they fucked up, but it's for sure United Alaska did.

The Swiss Cheese Stack of failure modes

n2burns ,

And the next paragraph:

The jet had been prevented from making long-haul flights over water so that the plane “could return very quickly to an airport” in the event the warnings happened again, NTSB chief Jennifer Homendy said.

Which makes it sound like they couldn’t find the source of that warning but weren’t willing to completely write it off.

Nevermind:

“An additional maintenance look” was requested but “not completed” before the incident, Ms Homendy said.

Darorad ,

I mean I’d much prefer they didn’t fly a plane that was repeatedly saying there’s a serious issue with it.

Dagnet ,

So the blinking engine light in my car isn’t just for festive vibes?

Bytemeister ,

It’s there to let you know that your damn O2 sensor is on the fritz again.

trafficnab ,

I’ll wait to pass judgement because, not being an expert, I have no idea what the standard procedure is for that warning appearing in 3 out of however many (hundreds of?) flights this plane engaged in over that period of time. With hindsight of course we can say “duh don’t fly the plane with the door about to blow off if it says it has pressurization issues” but maybe this is not actually a particularly serious warning in different circumstances.

unwillingsomnambulist ,

If I’m not mistaken, the Alaska Airlines accident aircraft completed 99 flights, as it went into service only a couple months ago.

Not an expert myself but I binge air crash investigation shows like nobody’s business, and this seems to speak to QC and maintenance workload/culture issues.

derf82 ,

Apparently it started immediately after Alaska installed their wifi equipment, which some sources have indicated requires opening that door plug. They apparently assumed it was due to the wifi install. Should have grounded it until the figured it out.

Alaska does have a history of poor maintenance causing crashes.

highenergyphysics ,

Surely this bodes well for their acquisition of Hawaiian, which famously operates long trans-Pacific routes across thousands of miles of open water!

GombeenSysadmin ,

Ex-aircraft mechanic here. Nothing will have been done in this situation without paperwork backing the decision. There are often small niggles that could ground an aircraft, but there are manuals that can be consulted to see how many more flights can be taken before it must be grounded for rectification - the MEL (minimum equipment list) and CDL (configuration deviation list). So the airline will not have made the ultimate decision to keep flying, Boeing will.

The fact that this has now been found in two different airlines means that it’s a design flaw again, either the locking mechanism on the bolts is insufficient, or the reinstallation instructions in the maintenance manual is incorrect (the Alaska airlines aircraft door plug was recently removed to carry out maintenance on another part)

ursakhiin ,

As an airline customer, I would much rather have the airline tell me the plane was grounded due to parts being ready to fall off than the 3 hours I had to wait one time because of a busted tray table.

GombeenSysadmin ,

If it’s not in the MEL or CDL then you can’t fly without it. They’re basically a book of approvals for how long you can get away with stuff.

Btw If the tray table can’t be stowed, you can’t take off with anyone in that row because of the danger in an emergency landing.

Bytemeister ,

Failure is a chain.

There's a one-sentence quote here, what do you expect them to say exactly as they find things wrong?

autotldr Bot , to worldnews in Boeing 737 Max 9: United Airlines finds loose bolts during inspections

This is the best summary I could come up with:


Bolts in need of “additional tightening” have been found during inspections of Boeing 737 Max 9s, United Airlines has said.

Inspections began after a section of the fuselage fell from an Alaska Airlines 737 Max 9 on Friday.

United Airlines said “installation issues” relating to door plugs would be “remedied” before the aircraft type would return to service.

In its statement, United said: “Since we began preliminary inspections on Saturday, we have found instances that appear to relate to installation issues in the door plug - for example, bolts that needed additional tightening.”

The door plug is a piece of fuselage with a window that can be used as an emergency exit in certain configurations.

It was this part of the Alaska Airlines plane which dramatically fell off mid-flight over the US state of Oregon, eventually landing in a teacher’s back garden.

steventhedev , to world in Al Jazeera bureau chief's son Hamza al-Dahdouh among journalists killed in Gaza

Sounds like Mustafa Thuria was the driver, Hamza Wael Dahdouh was in the passenger seat, and Hazem Rajab, Amer Abu Amr, and Ahmed al-Bursh were in the back seat (all three of those survived).

AFP says they were filming a house that was damaged by combat, so my guess is they were using a drone to gather footage that is close enough to the drones used by Hamas that the IDF considered it a threat to troops operating nearby.
