I think that the author felt that question had already been answered sufficiently by other papers -- his citations 1 and 2. The author was interested in adding pumping to the model, but as far as I can understand the pumping equations only

I think it was clear that the author wasn't finding the maximum possible distance, only the maximum achievable in a short amount of time. I say this because his graph of distance only went up with time, whereas we know that eventually

I'm sorry, are you actually suggesting that the Democratic Party blew up the Nord Stream Pipeline? Or that they fly on private jets more than Republicans? At the end of the day, they passed the Inflation Reduction Act, which is the lar

Yes, I addressed that in my comment.

I mean, if they could actually work then they'd be perfectly valid. Say Carbon-capture were at a point where we could actually say that my paying $100 caused an extra metric ton of CO2 to be extracted from the atmosphere. Then it actua

If you had $5000 that you wanted to use to fight climate change, and you wanted to have it have a bigger multiplying effect than your own personal consumption (install heat pumps, get electric car, etc.), where would you put that, given t

So I need to have as many apps as the number of websites I visit in a month? Hacker news, Reddit, NY Times, other news sites, BoingBoing, my kids' school, each restaurant, each airline I might ever book, Craigslist, etc etc etc? That&#

That's why I deliberately said "planets" vs "small rocks," for which this does not apply.

If I could pry further, that doesn't seem a "straightforward" answer to me, it sounds a little pat. Both my wife and I are teachers, and have kids, and we don't have a problem "teaching other people's children&

This "couldn't there exist..." is doing a lot of work that I don't understand. "Couldn't there exist different laws of gravity for big things like planets and small things like rocks, which explains why I'

Wow, that's a completely ridiculous strawman. My kids go to one of the most liberal school districts in the nation, and never once have they been told they need to "introspect their gender identity," let alone the absolutely

The author should make a coffee table book,, if there is collectors' interest in them and not that much easily-findable information (at least for westerners).

It still seems trivial to game. Make up some "tell" for your lies. Maybe every time you need to lie during the training period you squeeze your muscles, or think of hard math problems. It would be very hard for the AI not to fit t

But as far as I know no motor signals are sent to my mouth when I talk to myself (i.e. internal monologue), so this wouldn't read my thoughts. I'm not sure what you're saying.

Art teachers also have people copy existing art upside down, or turn their still life upside down (if possible). By trying to reproduce something upside down, your brain doesn't do as much pre-processing and chunking into preconceived

Can you explain? I didn't even know Romans thought about etymologies.

I think the implication was that it's kind of putting the cart before the horse. "Scientists hypothesize that Martian life and Earth life had a common ancestor" is pretty bizarre given that no Martian life has been found.

> One other good question to ask is [...] if it takes 30 years, we'd better also invest in alternatives, like nuclear. Yes. That's been my question from the very beginning of the thread. Glad we got there.

I'm not asking how long it can keep accelerating. You keep making things overly-complicated. We (per the estimates above) need to be installing about 800 MW of new renewable power generation every week every week for the next 30 years.

I disagree. Just because there's no sign of inflection yet in is earliest period of exponential growth doesn't mean that the conditions to keep building at this rate (or, rather, faster) will remain for another 30 years. We'r

Oil also doesn't make sense without subsidies. If renewables are going to compete, they currently need subsidies. He's simply saying that they wouldn't cover their own costs without the credits. Not that the credits somehow p

Sorry, I realize I was being confusing by measuring in 400 MW farms: the total required was 800 MW/week, which we're not hitting yet. We are at the right order of magnitude, though, as you show. The question is whether we can hit

While this is the standard answer that people who have looked into it deeper give, it still surprises me. The largest solar farm in the US is about 570 MW. Some have calculated that we're going to need to build two 400 MW farms ever

An odd hypothesis, I think. I don't think our ancestors were any less practical than us. Probably a great deal more practical, in fact. You reference Plato, but you could easily phrase it in the other direction. "From Roman engine
