they just gave them to you but wanted them back after the fights (which is kinda gross now). always assumed it was to prevent theft.

> deliberately chose a different connector so people won't steal the headphones.

this was alwaysmy guess.

Desalination is primarily done through high pressure filtration, no by phase change. It is more energy efficient, but still extremely demanding.

Also, the super salty brine needs to be disposed of, and can't just be dumped into one spot in the ocean or it creates a dead spot. You gotta pump it out into the open water in a current...

Basically, it's expensive. So you don't do it unless you absolutely must.

>can confirm that this method works.

No you can't. Unless you dug wells everywhere the dousing rods didn't indicate, so that you could check that there wasn't water there, then all you've done is dig wells roughly at random, or with some intuition based on geography and flora.

Depends on country. This was true at one point, but in the US 2G is gone a long time and 3G was discontinued last year

I flew in 2005 to the states as a young boy, they screened movies for everyone on a large screen and some foldable screens in the ceilings, flying long haul as a kid was soooo boring back then.

The maintenance required for a plane to stay airworthy is intense. It's not like they're flying for 30 years just getting the oil changed. The FAA does not fuck around.

If you always fly the same routes or company, you’re gonna see the same equipment. Try flying to another continent with another airline.

Regarding "what to do with the salt" wouldn't we be able to just use the salt from desalination plants and have that replace salt mining?

Obviously the concept is killed before even getting to this problem but I'm just wondering.

Please send me an example this is so interesting but Google hasn't helped

Joke's on them, I'm a kleptomaniac.

My theory is that they can hand out the nice headphones in business/first and they won't be stolen as much. There's nothing else to plug them into.

Economy class gets the cheap thin earbuds on a single jack and they don't bother to gather them back now. They're disposable.

Vikingar står enade, så att säga!

Corporations tend to act on a "ain't broke, don't fix" or ABDF policy, meaning if you don't need to replace it, then don't. This was not thought up by engineers, but by the accountants. When you take an airplane out of service to change something that isn't mission critical, in this case something that doesn't help a plane full of live humans take off, fly, and land with everyone safe and intact, then it's unjustifiably expensive, much cheaper to use those mass produced yet proprietary headphones. Besides, people tend to have their phones, tablets, and computers with them on flights and their own headphones, so it wouldn't make much sense to change the in-flight entertainment system, you can do that when you retire those old planes and buy new ones.

Emirates and Etihad both use those kinds

On 777 as well I think

It was weird, when I realized my Sony xm3 ran out of battery and Sony provides those 2 pin adapters in the pack. I always wondered why are they giving it till that moment last year and was so happy I had it lol

I operate in the climate space but am not an engineer or expert in water resources. So remember that as I give my understanding. It is very expensive. It uses a lot of energy. And it changes the salivation of ocean water around it which probably is not a good thing. The salt must go somewhere. And it can mess with groundwater. It is a solution of last resort.

The primary and least sexy way to begin the fix is conservation in a serious way. No more golf courses. No more home lawns bigger than x. Make wicked sure agriculture is using water in a sensible way. This is very hard but crucial - tackle the water rights monster and make it realistic and sensible. And a culture change. If your clothes aren’t dirty you wear them multiple days before washing. No washing hair everyday. Maybe a shower every few days with quick ‘army’ cleanups everyday. I know this sounds weird or far fetched but it is these type of mind shift that will help us manage in days ahead.

Nah bro, same for me.. Might be a Swedish thing

Not on already certified and installed seats they're not. If it's a retrofit program with new seats being installed, then yeah the audio jacks would likely get upgraded to the latest design. But if it's already flying the only thing those seats are getting is a half-hearted wipe with a dirty rag.

I'm not a fatalist.

Even if I was, what could I do about it?

It takes a lot of pressure and therefore energy to pump salt water through salt-removal membranes.

ACT seems to share a lot of traits with mindful meditation practices. Very interesting. Thanks again.

Emirates A380 , dubai Munich route, still has these 2 pin ones.

Most power plants do use water in their power generation, but it's largely a closed loop and freshwater is used. Fossil fuels/trash/radioactive decay is used to heat water which evaporates into steam and turns turbines, then cools and gets used in the cycle again.

If you decided to use saltwater in this process, the salt would be super super hard on the powerplant, piping, etc and dramatically reduce the lifespan and increase the maintenance costs of the power plant. You also wouldn't be able to generate water safe for use, as the water would likely be contaminated. You're better off with a dedicated power plant and a dedicated desalination plant.

Finally, you still need to figure out what to do with all that salt. If you dump it back in the ocean, you're going to kill off wildlife en masse and just generate more and more salt over time, as the salt concentration in the water you're pumping in increases. You can't dump it on land, it will completely destroy the ecosystem and you will need a TON of space. Unlike landfills, it won't decompose over time - just wash away (which means you're killing things elsewhere). You could potentially use old mines and such, but those aren't reliably structurally sound and you're still risking runoff or even worse, getting massive amounts of salt into the water table.

I always assumed it was so they could sell you the headphones, seeing as they used to sell the headphones
