On demand hyperloop-style water delivery
(reddthat.com)
Source is a 2015 xkcd comic:
When I was a kid, I asked my parents why our houses didn't have toothpaste pipes in addition to water ones. I'm strangely pleased to see Amazon thinking the same way.
It’s wild how ideas like Hyperloop were seen as reasonable ideas 10 years ago. The naivety.
No, it was insane back then, people were just too busy sucking elons dick like he was the second coming of Nikola Tesla instead of the hack Nazi he is.
I distinctly remember articles from the time calling out the hyper loop as a bullshit method to stop public transit. I'm entirely unsurprised California fell for the monorail salesman instead of just building the fucking rail system
FWIW I think there's still some merit in maglev vactrains that aren't tied to someone who was only pushing it to get public infrastructure projects cancelled with the goal of selling more cars.
At least there are seemingly serious academics and engineers still researching and developing the concept anyway.
I'm no authority on anything involved in such an idea, but I just can't imagine how the economics of a vacuum tunnel could be viable. The maintenance costs on constantly running lots of industrial scale vacuums sounds crazy expensive. I hate trying to keep good suction out my vacuum cleaner and imagine at huge scales things get harder, not easier. Maybe there are clever people who have a solution for that and it's not a big deal though. No clue.
The vacuum problems kill the Hyperloop design just like they kill any major mass launcher ideas from Earth. On the Moon both will work great.
Mass rail transit itself is something that ought to be more wide spread. Just not like that.
What if instead of using a vacuum and hovering, it was just a low friction contact instead? Like say steel wheels on steel tracks. You could digitally or even physically tie the cars together so you can adjust the length of it based on demand.
Shit, derived the train again
Romans had hyperloop water 2000 years ago.
Sell water bottles as a decentralized modular water distribution system.
On a similar vein, why haven't we banned dihydrogen monoxide? It corrodes our metal pipes, it destroys land over time, and it's in all of our crops! It's even in the clouds in the sky!

My tap water comes from ancient underground aquifers. While I realize it's not sustainable for centuries, for now we have pretty damn good municipal water. The only thing is slightly high, naturally occurring arsenic levels, which I filter out, but it's probably not necessary.
Nonetheless, people here complain about our water like it's Flint, MI. and buy bottled water?
My water/sewer bill is $50/mo. for two people. Some of my neighbors are paying hundreds a month. I don't know what they're doing with their water, but it's a choice they're making, my bill is proof.
Funny thing is, bottled water has extremely high levels of microplastics.
it’s not sustainable for centuries
It's sustainable until the Saudis learn about your cheap water and buy the whole system for pennies on the dollar so they can grow alfalfa for their racehorses. This is what's happening to my (currently cheap) water authority.
