Reply to comment by Bthejerk in eli5: Why is hold music so loud? by Happy_Jack_Flash
That makes a lot of sense for customer service calls! Would it also apply to doctors or schools, though? I asked today because I was calling my community college and they're probably the worst offender in my life, so in a fit of frustration I decided to ask while on hold 😅

Reply to ELI5: Desalination Economics by twodollarprophet
The main cost here is the energy cost. It costs a lot of money to power these plants. A secondary concern is what do you do with the various salts that you remove? Dump them back in the water? That would increase the local salinity levels and increase the energy costs needed to remove ever more saltier water.
Solar power could help, but the sheer amount of solar panels and batteries (to power during night) would make it rather expensive - as well as increase the local heat island effect.

Reply to ELI5: Desalination Economics by twodollarprophet
Desalinized water costs between $2.50 and $5 for 1000 gallons (down from closer to $9 a decade ago).
Freshwater costs around $2 for the same amount.
This means your water bill would go up from 25-150% if you switched completely. Even if you don't use that water you'll get charged for the creation of the plants. About $85 of a $150 water bill is for infrastructure and administration (I have to pay this even if I don't use a drop of water). The water I actually use only accounts for less than half my bill.

Attrition and slippage is a key factor in customer service. The fewer people that actually get through, the fewer dollars spent.

My theory is it’s an attempt to get you to hang up. Ever notice how when a company is trying to sell you something, you can’t stop them from calling, texting, emailing you? Yet when you need service, loud, long , hold times.

Reply to comment by Zumazumarum in ELI5 Why are pickles not just called pickled cucumbers? by Shabless
not sure why you're getting mad at me, I just share facts about fermentation and pickling vegetables with you from Wikipedia and other reliable sources, because I like pickling & fermentation and enjoy sharing cool knowledge.

Reply to comment by Orgot in ELI5: Why do people grow plants in greenhouse ? Is it more efficient than growing plants outside ? by dellive
Seeing your piped CO2 comment. Could you technically put a brick of dry ice in a greenhouse and let it vaporize off or would that just be a negligible amount of CO2? Small greenhouse in my backyard (about 6’ each side I’d guess) not some massive industrial greenhouse

Reply to ELI5: Desalination Economics by twodollarprophet
Desalination is costly, but when droughts are occurring it can be less expensive than other sources of water. unfortunately they cannot be turned on and off easily. Sydney has government owned systems that they will start powering up and cycling 3-6 months before they can produce significant volumes for use so they start turning them up well before droughts reach that point.
That is the same issue with some of California. There is a project going by the name of Poseidon in Southern California where private investors are trying to get contracted to build desalination facilities, but part of that agreement requires the local communities to purchase minimum amounts of water if they need it or not. The private companies do not want to cycle the plant down and loose their income, so they want to shift that cost onto the taxpayers and local utility company.

Reply to eli5 Why does it seem that there are barely any serial killers anymore, when there were so many just a few decades ago? by [deleted]
probably the internet. i’ve never murdered anybody but i wouldn’t even try because of the technology that’s available… really easy to get caught i’d imagine in 2023.

The very large cost of doing this: desalination is an extremely expensive way to get fresh water. This is less of an concern in the Middle Eastern countries who have oil money to waste.

Reply to comment by Lirdon in ELI5 Why haven't scientists cloned extinct animals such as the dodo, the Caspian tiger, etc.? by LesChatsVerts
It's okay, I just always had a soft spot for Tasmanian Tiger. I think they were lovely.There's film footage of the last surviving one and he looked so sad. I read he gave a photographer a nip on the butt once, don't know if it's true.

Yeah, my bad. My memory failed me. Tasmanian Tiger is what I thought about.

Maybe we should look into buying local products, instead of shipping them halfway around the world. Just sayin'.

Cured from blindness, became a saint.
Just pick and choose whatever you like. That´s how it works, no?

Reply to comment by chosen-username in Eli5: why are there tigers in Siberia but not in Scandinavia? by chosen-username
A long time ago, there were some species of saber-toothed cats. Today there's the lynx, much smaller, and, just at the edge to Asia, a leopard subspecies.

Reply to Eli5: On a production line, how do they make a car, plane or anything else be identical from one another without differences? by SideburnG
Like others have said, they are not identical, but have tolerance requirements that must be met. I work in the aviation field and a lot of our tolerances are measured in increments of one ten thousandth of an inch.

Reply to Eli5 do car batteries do more than just start the car? by brandibythebeach
Have you checked the water levels in the batteries? There are two rectangular caps between the posts on the battery. Pop them off carefully, and you’ll see three holes that have water in them. Try to use only distilled, but hard times is hard times. The battery won’t charge if there’s not enough water to conduct the current.
