While it would be cool for it to appear the size of the moon, it is not necessary with a shaped mirror.

You can keep the same size in a higher orbit, maybe even geosynchronous, then sync the rotation of the mirror to keep it pointing in the same spot on earth.

Granted a shaped mirror that size would be much harder to put into orbit than a flat mirror.

It's certainly a stupid idea if your trying to illuminate at the suns level, but if you wanted an area to have permanent moonlight? Not so unreasonable.

The moon is 400,000 times dimmer, so 1km^2 of mirror, which is ridiculous, could illuminate an area the size of Germany.

New York metro area is 12,000km^2, which would only need a mirror 173m on each side.

Actually might not be a bad tourist attraction for a crazy city, permanent artificial moonlight.

I've only tangentially heard about this, but another issue is that doctors in the US don't have to, and aren't encouraged to keep up with recent research.

Combine that with a medical education system that hasn't changed drastically in 70 years to keep up with that new research and most US doctors are just out of date.

Grid storage wouldn't be lithium ion, something like lithium phosphate would be better.

Step one, buy in bulk to get a price closer to $150/kwh

Step 2, use for much longer than 2000 cycles, lfp have much longer expected lifetimes, and since space/weight aren't a huger consideration, you can replace individual cells when they go bad.

Step 3, produce your own energy, if you have your own energy generation, you don't need to pay grid prices, and profit is much better.

Disclaimer, I am not an expert in this at all, but this is how I imagine it could make sense.

It seems like it's best use case would be in conjunction with nearby buildings. Where the waste heat can be used for heating.

They've had fab problems for years, in that it cost them a ton on money and much longer than desired to shrink nodes, so they've fallen from a leader in fab production to being behind.

Not to mention there's not much money to be made from fabs, unless your tsmc.

AMD, Qualcomm, Nvidia, Google, Apple, are all huge tech companies that design their own cutting edge chips, and only Samsung is another company that both designs and produces chips.

Ehh mastodon and lemmy don't see a ton of cross talk. Threads is mainly going to affect mastodon instances.

Huh, well I got myself a galaxy watch 6 for like $200, and so far it seems solid.

It easily lasts a day, could probably go for 2 if I tried.

I'm confused, that looks like an m.2 slot, and it's not like it could really be anything else. Msata is a dead standard and looks quite different. The slot would be too wide.

. 5% in a swing state is not nothing, could very much make the election in a state like Pennsylvania.

Beans, I hate pretty much everything about beans, taste texture, they look gross and smell gross.

Yeah the strategy is : don't cannibalize ice profits by releasing sensible evs.
