That's how the people around me have always used it in California and New England.
That's because putting solar on rooftops makes little economic sense. The overhead in terms of installation cost was relatively insignificant when PV panels cost 20 times as much - as they did 15 years ago. These days, the cost is swamped by installation costs.

These days, the only place it makes sense to put PV is flat on unused or unproductive land. The 95% drop in PV panels means that it is no longer economic to bother with mechanical tracking in solar farms. Integrating panels into a domestic roof destroys the incredible cost advantages PV has over alternative power sources.

I have a lot of packages delivered to an Amazon locker. Item delivery is inconsistent if the locker is often full. Sometimes items are marked refused delivery, sometimes locker full and sometimes lost. They should have cameras inside the locker boxes to show what was actually delivered and picked up.
Honestly, this dismissive comment helped me formulate a thing in my mind.

So, as a Black American, I do believe it's important to hear from the voices of people who are suffering.

That being said, I find that, unfortunately, that market-in-books tends to really lean into the suffering, and I say it's important to consider the extent to which that might weigh down the writing and the reading experience.

This is the primary reason I bristle at the idea of "getting away from e.g. white male writers." There, of course, is nothing inherently better about them; but our unfortunate social / cultural / historical filters have made it so that (easily findable) writing that is free from certain kinds of suffering comes from them -- and sometimes you need that too.
>We should not expect statistically significant contributions to the fight, until the most promising technologies have been scaled up massively.

Just to put a finer point on it, we do not want a large scale-up until we largely stop burning fossil fuel for stationary baseload power.

Otherwise when you zoom out and look at the whole energy system, you're just "digging a hole and filling it back in again" (I mean this both thermodynamically and economically), plus adding unavoidable inefficiency losses at every step. So in reality the entire chain would be generating negative net energy for society. Such a futile energy system isn't a workable solution, obviously.

No, right not we should be researching and laying the groundwork for a future (post-combustion) scale-up, but environmentally we should not be scaling up just yet. Scaling up right now would actually generate more pollution, not less.
It's all fusion with extra steps, but your point stands.
CO2 is mixed in the atmosphere on a timescale short compared to the timescale for its natural removal. Also, there is net transport of CO2 upwards, since most release is near the surface.
> EDIT2: and yes, we've already tried blockchain for that too.

We've not already tried blockchain for this. The rails are there, just a small matter of implementation. Everyone's too busy building shovel factories and not enough people are mining for gold to make a web3 micropayments product.

I can, right now, buy $5 of solana on Coinbase, give you $0.05, with an inconsequential fee of $0.001 or so using Solana, and with enough $0.05 payments, you can cash it out via Coinbase. It works on web on desktop via a chrome extension, I'm still working out a solution for mobile.

I'd love to have an Internet reading budget for the month and have that automatically get disbursed to the writer if I read past a certain point in the article. The rails are all there, just a small matter of code and then getting adoption.

> The experiments that showed this were confusing correlation with causation. High CO2 in rooms is a marker of reduced O2, and a lack of fresh air.

Not to a significant degree. Oxygen is normally around 20.9%, if you raise CO2 levels by 1000 ppm, that goes down to… 20.8%. There's a bigger change to how much O2 you breathe just from the change in air pressure from going up 10 meters.

O2 turning into CO2 becomes lethal at 4%; if O2 concentrations go down in step with that (e.g your breathing causes it) you'll only be drowsy and nauseous from the latter while the former is killing you.

This distinction is also why diving rebreathers work: they remove the CO2, which is toxic much sooner than the mere lack of oxygen.

Also:

Fresh air contains less CO2. In Bohr's day, fresh air meant something like 280 ppm, today that means 440 ppm. If some future atmosphere contains 1000 ppm, that's what "fresh" means in that case.

I'm at least marginally confident you're just misreading the Bohr effect.
I don't disagree with you, but I don't think carbon capture will provide the gains needed in a realistic timeframe. I don't think its development should be abandoned, but we all have a tendency to go to sleep thinking "cool, tech will solve this for me" when in reality only public policy will.

All of our governments are owned by these corporations that are trying to either continue making money via the status quo or make money with these fly-by-night tech-will-save-us-all get rich quick schemes. Nobody is bribing the politicians to enact policy that cuts global manufacturing output.

Re: burial: wood vaults might be feasible. You dig a hole, and bury wood in an anaerobic environment. We're pretty good at digging landfills (or use an existing strip mined location) which is basically all this is. Then you grow more trees on top of the landfill, rinse and repeat.

It remains to be seen if this can actually be scaled up.

My Encounter with the Fantasy-Industrial Complex
Love me some computer books.
I never see them in the US outside of city bike share programs, but I feel like most casual bike users would be better served by internal gear hubs and similar closed systems. The maintenance is minimal, outside of dropping some oil in every year.

But for some reason, every bike in a bike shop, including the most casual upright bike, has a finicky derailleur.

So instead we’re doomed to a life of misaligned derailleurs and bent derailleur hangers.

Python-Based DSL for Generating Verilog Model of Synchronous Digital Circuits
I can't see how mid-drives are significantly superior. An electric motor doesn't need any gear advantage and sending more force to the rear wheel seems like it's actually a disadvantage since it put more stress on bicycle components that are often designed for just human levels of force.

As far as I can tell, the mid-drives became dominant just 'cause people wanted to have something the looked more "seamless".

I have rear drive ebike (Avanton Pace 300 v1) and I'm very happy with it (it was also cheap as a show room model). It's responsive and I can pedal up any hill to about a 25% grade. The controller is still mid-frame and the battery inset into the down tube. Thinking about it, my ideal ebike would be a heavy duty frame with all the components just bolting on (plus could use power tool batteries).
So is never.
I’m generally a bit of an LLM skeptic, at least as concerns extravagant claims around “AGI” or self-improvement of any of that nonsense.

Of all the highly optimistic applications for 2024 LLMs, mathematics sounds pretty plausible?

You probably already know this, but I think it bears pointing out explicitly: in this context we're not talking (only) about LLM's. There's a LOT more to AI than just Large Language Models, and the list of resources linked reflects that.
Yeah, this sounds like classic somatogravic illusion. When you experience forward acceleration with no outside visual references, your vestibular system produces the sensation of tumbling backwards. The natural response in an airplane, it you are not well trained, is to shove the stick forward. I've seen trainees do this in this exact situation (a go around in instrument conditions) and I've had to take over the airplane to keep us from auguring in (just like this captain did).

In other words, this has absolutely nothing to do with the aircraft. This is a deficiency in the first officer's instrument flying.

Luckily most people are sleeping in the middle of the night, so electricity usage is already quite low. That's why many areas already have a separate discounted Night Tariff.

Additionally, the winter might not have a lot of sun, but it usually does have quite a bit of wind. Build a combination of solar and wind power, and you've solved the biggest issue. The rest can be picked up by hydro and gas peaker plants (short-term), or battery storage and other new technologies (long-term).
Yeah my bad, I meant that glacial and interglacial periods happen in a cycle that can take up to 100k years before it repeats, but phrased it in a way that's outright wrong as well as misleading. I think the overall point still stands though.

I know our roof is in pretty bad shape, and will need to be replaced in five to ten years. The house was built in the mid-80s, we bought it in 2008, and I know it’s had at least one or two roof replacements in that time.

Most roofs aren’t even built to code, which is supposed to be the floor below which building quality cannot go. Instead, they build to whatever they can get away with, and in many places, that is much lower than code because the building inspectors are busy and don’t check, or they’re careless, or they get bribed off.

In most single family homes, the more you learn about the construction of your specific house and what standards they were supposed to build to but didn’t, the more horrified you will become.

Like the builder leaving out a $2.00 piece of flashing because either they didn’t care, or they thought it was too expensive. Of course, the result of that $2.00 flashing not being there is tens of thousands of dollars of damage that occurs to your house over the next decade-plus, for which your insurance company will pay precisely $0.00, since it’s not the result of a single catastrophic event.
Fair point, but it's a risk I'd be willing to take.
Seeing how as I regularly managed to break the drive cross in my 3-speed SA hub just by pushing the thing real hard under pedal power alone - this is 40 years ago - I don't think they're particularly strong. I fixed my bike by myself so all this cost me was a new drive cross but still, it shouldn't break in the first place.
Uranium's energy derives from gravitational collapse, not fusion. The neutron stars whose collision produces uranium have undergone endothermic nuclear reactions; their nuclear matter (aside from its gravitational binding energy) is at a higher energy state than the initial protons and electrons.

Geothermal is most either primordial gravitational energy from the Earth's formation or energy from decay of uranium and thorium. Only decay of K-40 might be ascribed to fusion.

Tidal is derived from gravitational energy.

>The exact number of grains of sand on a specific, untouched beach.

Just saying "specific" is not being specific.

It's like it is compelled to be unspecific and not exact and be generic.

Seems a bit counterintuitive for panels made out of lead. Being toxic and not very long lasting doesn't seem like the best combination tbh.
That is certainly the correct approach but most companies I have worked for, or interviewed with, claimed to only hire the best talent. Then reality hits and one of two things happen:

1. They hire only super talent but do not define what talent is. The result is a compatibility contest to the unspecified technical experience or desired style of the interviewer.

2. They settle just to fill a seat. They look at what’s popular to developers and then hire the 60% segment in the middle of a bell curve. This is problematic because once you get there by definition you are not allowed to be the best without ignoring internal processes/tech and alienating your peers.

MEI only works if there are qualified definitions of those terms and all hiring and rewards are limited against those definitions. Other industries solve for that with a combination of licensing and/or industry based metrics.

I have never seen unbiased MEI in practice either myself or from people I have talked to. It could exist, but if it does it is beyond exceptionally rare.

I bet if you took the subsidies from fossil fuels and dumped it into carbon removal you could solve both problems at once.
> our current battery tech can’t improve fast enough to supplant fossil fuels in the time frames needed.

I disagree. The tech itself already good enough to supplant the majority of cases, which in turn gives us more time for the things that remain (such as long-haul aircraft).

That said, I may be a little on the optimistic side about how much warming the ecosphere can take. If it's already too hot, then yes, naturally you are correct.

> Interesting that you mention fusion though considering fission is available today and provides a substantial amount of power (not to mention actually reduces the amount of fossil fuels whereas solar has a negligible impact on fossil fuels and at best is only absorbing energy growth).

That's not what the graphs show: https://ourworldindata.org/electricity-mix

• Coal: down since 2012

• Gas: close enough to steady since 2012

• Nuclear: down since early 2000s

• Wind and solar: up

Looks to me like gas mostly replaced oil (since the late 90s); and that wind+solar is displacing nuclear (since the former became big enough to show up on a graph).
