Hi all. Technical difficulties and a lot of irl stuff means I can't mod as much as I'd like nowadays, and since I'm the only one here that means it's not maintained.

If anyone's interested in being a mod then just lemme know and I can grant that; if anyone wants to take over the community then even better. Note that you'd preferably want some experience and willingness to moderate.

This is a graph showing official number of deaths in Germany for every day since 2020. The red line is for 2026 and the big spike is the recent heatwave. The three days with the most deaths since at least 2020 have all happened just two weeks ago.

So the reality is that range increases are due to battery capacity, which is not really "efficiency".

tbh more like data is ugly but I like it
