  • The talks in Davos will follow a meeting in Malta in October, which was attended by around 70 countries from around the world as well as the European Union (EU) and the UN. Russia was not present. The Ukrainian peace plan foresees the immediate withdrawal of all Russian troops from all occupied territories, including Crimea.

    So this isn’t some major change or Ukraine planning to negotiate with Russia, more of a “hey world, how do we get Russia to fuck off” meeting.











  • Indeed.

    I guess you could also use an oversized heat pump in theory. With a setup like this, recirculation and/or wastewater heat recuperation would also need to be looked into. Either would significantly reduce the cost of running this.

    But purely resistive heating without any form of recuperation would need impractical amounts of power.


  • Water typically comes in at around 15 degree Celsius, so it needs to be heated by around 25 degrees to feel warm.

    A regular high flow shower head flows up to 20 liters per minute (that’s 5.3 gpm in American). That’s 500 kcal/min of energy that needs to be added, which is 35 kW, or a total of almost 150A at 240V.


  • Are there schools that don’t teach calculator usage? Even 10-15 years ago German schools (at least in the states I looked at) had the option to teach math with either basic calculators, scientific calculators, or computer algebra systems in grades 9-13 (I think) with most schools picking scientific calculators even back then. I would expect that to have moved into earlier grades and more advanced devices nowadays.
