There's is an interactive chart that's easier to understand

Now if I take the french grid example that I know best, for the past 7 days the usual spot price is around 100 to 150€/MWh but between 9am to 6 pm it is greatly reduced due to solar production, frequently down to 0 like today (current heatwave, lots of sun). And today between 1 and 3pm we had up to 5GW of solar production being curtailed. That is on top of the nuclear plants already reducing their output by up to 8GW around noon to accommodate solar power. Hydraulic storage was also running but tops at ~3GW.

That is to say there's already unused energy during the day, in theory, if you had a MWh battery you could have charged it for free today (sometimes even been paid to do so) and earned 100€ a few hours later.

One thing I see coming (albeit slowly) is EV cars phasing out IC engines, that once plugged on the grid with their big batteries could be a good distributed storage solution: they recharge during the day whenever the price is low and smooth out the expensive peaks when possible.

I went back to re-read reflectorbital.com, indeed if you're only lighting a solar farm in the middle of nowhere maybe the light pollution is not so bad outside of the targeted zone.

Still fells like a complicated solution to me. Imo we need more storage innovation and investment, a lot more. We know we'll have more and more intermittent renewables electricity production, we just have to store it.

In this article: https://skyandtelescope.org/astronomy-news/new-kind-of-satel...

> calculated that the Reflect Orbital spacecraft would appear as points of light with a magnitude of -15 [...] might damage the eye.

-15 seems ~10 times brighter than the moon (-12,6) if I got the formula right so it would indeed be very bright.

Reminds me of all the led lighting we have now: one evening on a random street I watched the cars, bicycles, shops, street lamps: all leds, yes a bit brighter and colder than the old bulbs I know, buuut the light sources being very small dots (with no diffuser), it feels very harsh to the eye, at least to me.

Anyway, even if it proves useful for something, it would join the long list of innovations doing one thing at the expense of everyone else (externality == light pollution in this case).

Like how much time is there between 2 and 3 am? Usually one hour, but sometimes 2 and also sometimes 0. It looks simple at first but it creates a lot of edge cases that your business logic now needs to handle and we had a fairly complex system for this.

But I feel there's not a lot of trust that whatever implementation we could end up with wouldn't be such a dystopia. The real world equivalent would be checkpoints at every intersection verifying the driver's age, the cashier who carded the 20 yo with a beer now does it for everyone, makes a copy of your ID and stores it in a big folder shared with their 427 "business partners".

Imo we should scrap the whole idea of age verification. Kids get a kidPhone with kidOS, whitelist of age-appropriate resources & capabilities. You wouldn't let an 8 yo drive on the highway, yet they can have a supercar to drive unsupervised on the information highway, no biggie. Internet is full of adults doing all sort of stuff while kids need supervision and education: design safe spaces for children, not checkpoints at every corner.

There are horse endurance races where the winner arrived in 7,5 hours after 160km[1]. That's a sub 2-hours marathon almost 4 times in a row (not to mention with a guy on your back).

I always use an adblock where possible. 1. I've seen too much ads trying to straight up serve malware. 2. I'm definitely not okay with the ad-industry data aggregation tracking my every move online.

Plus the algorithm is kinda dumb: I see you bought a mattress, how about another one, every day, for the next months? I was curious once about a product I would never buy but now, weeks later, I still have ten companies paying ads for the same product, each one claiming to be the real deal.

I still use google news on mobile, no adblock there, some publications are okay, others are, well... I take a screenshot when there's 0% of content on the screen → OnlyAds/NoContent folder.

Do we know how they get that? Because my fingerprints are also in there, so...

As lots of people seem to always prefer the cheaper option, we now have single-use plastic ultra-fast fashion, plastic stuff that'll break in the short term, brittle plywood furniture, cheap ultra-processed food, etc.

Classic software development always felt like a tailor-made job to me and of course it's slow and expensive but if it's done by professionals it can give excellent results. Now if you can get crappy but cheap and good enough results of course it'll be the preferred option for mass production.

That being said, Robespierre was a key participant of 'La Terreur' where tens of thousands of people where hastily judged and executed and he himself ended up executed 4 months after that speech. [1]

The oldest account I found is in a religious book from 1832 [1]: "We must have nothing to hide, nothing to fear", but, and this is the important bit, this is in the context of your relationship with Christ.

Later accounts are mostly from judicial documents like "well tell us what happened, if you have nothing to hide, you'll have nothing to fear".

And later on we start to see the current form of the argument related to privacy, except now this argument is never directly used to erode it. It will always be in some form of "ok now we have to do this collective thing because of criminals, because of terrorism, because of protect the children, etc.". If you search "nothing to hide, nothing to fear" 100% of the results are about how it is a logical fallacy, nobody at all seems to defend the argument and yet, here we are!

Food for thought:

- this argument may well be stuck in the collective unconscious of lots of people (albeit in the religious context)

- many governments, organizations and in any case the people in position of power and authority can develop a god complex (power corrupts etc.)

So unless I end up dealing with an all-loving and all-forgiving entity I could fully trust, I'd like to keep my right to privacy, thank you very much!
