I bought LFP batteries from Ali Baba just a couple of months ago. 100ah 3.2v x8 to boost my 100ah 12v to 300ah. Cell prices were about 60% of what they were in August, and curiously smaller in volume.

The graph show emissions going down in Africa, slow but steady. In fact they are going down everywhere (even globally) except for Asia. China right now is growing its coal stations alongside renewables capacity as ‘peakers’, but it doesn’t

Yeah but they have a mix of 80%, with Oceania the not-even-close second of 40%. South America are doing so well it seems like an anomaly on that graph. And it’s fair to say it’s trending up again after a long slow decline

Home battery systems are getting absurdly cheap. Grid scale will follow, but before then it would be cheaper to incentivize rooftop solar and home battery installations in places where there’s plenty of sunlight (e.g., most of Australia)

Reinstating capital punishment would be piling a wrong on top of another wrong. So many people have been executed only to be posthumously exonerated. The justice system isn’t perfect, and the death penalty presents a greater potential for i

Just curious why it’s not a ‘good thing’? The only thing I can think of is it would be bad in the situation of a monopoly, but that’s not the current situation. Otherwise, it seems like an emergent market is being accelerated, and I, the

This is something that Elixir nailed. The typical idioms for return types are `{:ok, ok_value} | {:error, error_value}`, for which callers can pattern match against and handle appropriately. If fail-fast is desired, many functions will al

Yeah. I think even though the article doesn’t use it as an example, what’s really desirable about escape hatching to a systems language is the ability to in-place mutate lots of data. Specifically sparse mutations of a large chunk of data w
