Tangential but as an effort to go green- I'm considering not buying new Led acid batteries for my UPS and reusing the old ones from my old laptop. Does anybody know if this can be done?
Lead acid batteries are highly recyclable, and more easily recycled than lithium ion cells anyway.

Fair chance old laptop batteries are going to be well and truely past their serviceable life. Lead acid batteries are highly recyclable, and more easily recycled than lithium ion cells anyway.
I wonder what sort of shift happened in recent history such that S Africa is now a region where “electricity supply is erratic or non-existent.”

I wonder if solar plus batteries will become more common than the power grid in some of these countries, making the power grid redundant.
Tesla batteries being used as a big UPS for mobile base stations. Nice idea for remote stations! Fun fact: from the metal mesh grill (cabinet on the right next to Tesla) looks like it's Ericsson equipment being powered.

By old I mean used not old-by-age. I usually buy a new laptop every 3 years
I’ve seen some blog and YouTube videos where people have repurposed 18650 lithium ion cells.
There’s a bit to it, but it’s doable.

There are problems with that. For one, consider that if all of a country's debt were denominated in bitcoin. For instance, the government issues bonds that can be redeemed when they mature for some quantity of BTC. Now consider what happens if the value of bitcoin goes up suddenly. The government now is much deeper in debt than they were planning to be. Sometimes having your own currency has benefits, for the country…
These mechanisms you mention are all mechanisms that have historically been used, but there is a widespread consensus that it's not the right thing to do. Best practice is that a central bank should be independent of government and their mandate should not be to meddle with the valuation of a country's debt but to keep the value of the currency stable. For example, for the ECB it would be completely impossible to mak…

After two major strawmen why should he add another reason?
Why does GP feel need to note that they are a Tesla critic rather than simply praising Zimbabwe's elegant use case? Snarkiness abounds, apparently.
