Sustainable generation is only half the story. To have parity with fossil fuel or nuclear fuel generated energy, there will also have to be cost-effective high capacity quickly recoverable energy storage, because that's what the fuels in fossil/nuclear fuel energy also provide. Stored energy, on tap / provided at will, and not just by accident like wind (if it blows) or solar (if it's not cloudy). Adding storage of energy into any equation drastically changes what makes the most sense.

The layering is half the story. The article should have emphasised the "well-fitting" part of the FFP2 design more.
A 94% effectively layered FFP2 that fits well over mouth AND nose,
is much better at stopping viral spread than a 95% effectively layered rectangular mask that leaves sides and occasionally, entire noses uncovered.

I mean, seriously, Getter? Get her?

That's diningenuous to many parents of Asian origin in the USA. ;-)

So where the F is dark mode in the Slashdot Options menu?

I want to upvote this. Why can't I?
The big problem is overpopulation of the planet by humans. Zooming in on smaller subsets and the specificity of the problems caused by them is tantamount to instigating witch-hunt. I find it very hard to refrain from placing a Godwin here.

Indeed. Pixels

IotBS was based on Defender, not Space Invaders.

I'd not judge Lion Air or Ethiopian until it's clear whether the safety certification for the 737 Max was obtained WITH or WITHOUT the "optional" features on board. If it was WITH, then Boeing essentially sold an uncertified / incomplete product to those two airlines, probably without clearly telling them so.

At least they had a fallback system / contingency plan, that seemed to have worked. That makes Gatwick do better than approximately (my approximation) 80% of airports in cases like that.

Remain? ESA is sciencing rings around NASA in space, China and India have essentially caught up to nearly equal capability, American astronauts need to hitch a ride on a Russian Soyuz to get to the International Space Station and the one American company that still has some (impressive) launch capability is actually founded and led by a South African.
Methinks the US as an entity have some catching up to do when it comes to "Space Leadership". It's more of a committee of nations now.

Please mod this up to eleven?

Has Donald Trump started planning the wall to keep them away already?

because 48k is more than enough for anybody.

Ironic. The link to the article begins by complaining about my use of an ad blocker in my browser. So what was newsworthy about that article again? Shameless linking of online behaviour and personality profile? You wonder how they got all that data.
