Interesting, thanks!

One thing I'd update is that early in the article you say that for switching from diesel to lithium-ion, "It's 16 tonnes of payload that disappears".

But then later you take engine efficiency into account and say it's "about 6.4 tonnes of battery".

So the claim that it would ever reduce payload by 16 tonnes seems incorrect, and not everyone is going to read both parts.

Can someone explain how wind can spiral in to a point? Where does the air "go"? Or does this create a higher pressure?

If it’s showing surface winds, it goes up. On windy.com there’s an altitude slider that lets you choose which wind level you’re looking at. Haven’t found that yet here.

Oh thanks that altitude slider is very interesting. Makes me want to see a 3d visualization.

aside: interestingly it's spelled bellwether and comes from shepherds putting a bell on a wether (a sheep) — it's unrelated to weather

TIL thank you

Tim Cook has been spending a lot of time sucking up to Donald Trump recently, so I think the U.S. federal government will only be assisting Apple

> Maybe the world will be a more peaceful place if it doesn't get too hot?

I think you're saying this as a joke, but to me it seems extremely likely that climate change will lead to wars and conflict (if it hasn't already)

*pore through

(not a judgment, just mentioning in case the distinction is interesting to anyone)

yeah Firefox on Linux gave me bad margins too, whereas Chrome on Linux printed perfectly :'(
