That’s another mostly great article you linked to. Still though it doesn’t mention the dramatic cost increase of natural gas plants when used as a peaker instead of always-on, and it assumes we can produce as many batteries as we want. It a

The article on the site about solar is equally bad. Both are full of lots of good information but then have some key misunderstandings. The solar article doesn't acknowledge that installing a solar requires installing a gas peaker plan

The statistics that are given in these articles make the situation sound a lot worse than it is. At least in this article they say “traded food”. The point being that less than 10% of global production is traded. The world could survive Ukr

As to the answer to the title of this article: the article states that the sleep numbers for primates come from captivity and that when they did a study in the wild the number was far less. So there’s not quite as much mystery here as it fi

The opener of this article references the 7 hours of sleep figure for hunter gatherers which is from a quality study using sleep tracking devices [1]. But please note that’s actual sleep: you may need to be in bed for 8-9 hours to get 7 hou

Where did you get the notion that the energy usage is planet destroying? Current Bitcoin usage is literally a rounding error of global energy usage (0.1%) and if wildly successful would still be < 1% of energy usage. https://w
