Which is why it gets ridiculous. You can build an oven with a few conveniently shaped rocks. You can build an over with raw river clay, then use that oven to make better bricks, then use those bricks to make a better oven, which you can use to make even better bricks.

So, all it takes to turn somebody into a greedy capitalist exploiter is...the ability to stack rocks into a box with an opening.

Rural ISPs often wire up farms as a core part of their business. I remember when Cambium released a firmware that allowed for the Canopy series of fixed wireless broadband gear that allowed for a CPE to slowly physically move, doing all of the re-ranging and what not to allow it to be, to a very small extent, mobile. Why? So that an SM could be mounted to a tractor.

It's also where you learn that corn silk really fucks up with 5 ghz RF.

The greater metropolitan area of Mexico City uses around 7.5 billion kg (liters) of water per day.
(25,000,000 people using 300 liters)
Lithium is about 100 parts per billion in sea water.
So if you desalinated enough water to supply Mexico city, and sorted off all of lithium, that would be 750 kg per day, or 270 tonnes per year.
Annual global lithium production is about 290,000 tonnes per year.

Desalinate water for all of Mexico city, add an extra 0.1% to lithium production.

Color me unimpressed.
