They already have that policy, as the article notes. The problem is, how do you enforce it? As the comment you replied to notes, without requiring an ID verification, anyone can say they’re any age.

At what point does it become the parents’ responsibility to monitor what their kids are doing online?

Changing what policy, and to what?

👅🐴 … There is not a raisin emoji.

That’s a good point; it becomes less economical if you need multiple of these cells just to counteract the self-discharge. Even so, it’s really just a demo of the technology; they do mention they expect to have a 1 watt model later this year.

Almost nothing… Maybe some very basic scientific equipment, but they do note that they’d be able to use multiple batteries layered to produce higher output, and that they’re expecting to have a 1 watt version later this year; that’d be far more useful in practice.

This is wild; the battery would outlive the electronics it’s powering in almost all cases.

The output is incredibly tiny, but I wonder if it could be used to trickle-charge a higher-output battery for use in electronics that only need to be used infrequently for short durations.
