> I think about 2 ton battery is closer to truth for a truck that has about 400-500 mile range. A Tesla Model 3 has a ~ 500 kg battery and weighs ~ 2 tons. With the drag coefficient of a truck being significantly greater and its gross we

I'd guess the one important application of fuel cell tech that people often appear to forget is going to be long haul trucks where it'll replace the diesel power train. It's a big chunk of overall land transport that IMO in t

Easy one. Apple pays a premium (to their suppliers) compared to what other non-luxury-hipster-feelgood companies can, thus buying up those (more or less) green capacities (which are scarce). Which leaves those other companies less of these

It is somewhat better than them not even trying. The problem I see: if they partly succeed, it will convince many people that things (carbon dependency) aren't as problematic as they are .. which is .. not so good.

Decarbonisation is so utterly not going to happen to a sufficient degree by 2030. And if Apple were to succeed, under our current political systems, it'd just mean, they'd have made their customers pay a premium to push carbon emi

AFAIK only read only snapshots can be sent and received. It kind of makes sense, since a writable snapshot could be written to during the send/receive so that the remote result would not match any clearly defined local state. A receive

I don't know about the API but as far as I understand the man page, there doesn't appear to be a way to delete a subvolume on the remote side by doing btrfs receive. That btrfs receive may well be exploitable (because of some bug)
