I feel like technology is at the point where we should be seriously considering the idea of personal computers that are intended to have twenty year usable lifespans. (That includes software stacks.)

Stopping people from using AI is sort of like banning people from doing math. Maybe it can work for awhile, but in the long run computers just keep getting faster, and algorithms to make effective use of existing hardware get better. I&#x2

Ah, I missed the "read full article" button and thought the first couple paragraphs was the entire thing. (It seems like they could have included that detail in the intro.)

At one of the mini maker faire's at OMSI (a science museum in Portland) in past years, there was a guy with a penny sorting machine he had built. The machine would sort pennies by shininess, and direct them into the appropriate column

Reducing total energy consumption by 80% isn't going to happen short of a nuclear war or equivalent event. Even with fairly extreme energy conservation efforts, the total amount of electricity used is likely to go up as people switch

I live in Oregon; we have a lot of dams on the Columbia that can be used for intermittent power. I don't know if they have a capability to pump water upstream at Bonneville or any of the others when they have surplus power, but that s

Give it a few years; solar and batteries are getting better and cheaper, and the kind of grid interconnections needed for power sharing to even out the intermittency of renewables aren't going to be built in a day. It's an ongoin

Another thing (that the story goes into in depth) is that cheating creates a whole lot of extra work and stress for professors who would rather just be teaching material and not exerting enormous effort into policing other people's beh

I would think it's the other way around: beaming power up, you're less likely to hit people and buildings and terrestrial animals. You'd just hit birds and potentially planes and satellites, but planes and satellites can be

Technically my motor controller can be passively cooled too, it's just not recommended. (It automatically goes into a low-power "limp" mode rather than burn itself out.) I'm not sure how much power it can handle continu

I'm doing an EV conversion, and have trouble wrapping my head around the idea that a motor controller that weighs about ten pounds or so and isn't much bigger than a loaf of bread can handle about 100 kilowatts of power, convertin

I can't say I haven't been tempted in that direction. How's the tuning stability? Does it track v/octave well across a wide frequency range?

Nice site. In my case it just confirms that where I'm at (vicinity of Hillsboro Oregon) we've been having an unusually cold and wet spring. Some of the plants are only just now putting on leaves. I'm sure we'll return

I think something like that would have to be manually audited by humans (i.e. you'd need to agree on a central authority who certifies volumes of carbon sequestered). I was thinking the other day that maybe something that could be easi

Efficiency was what I was wondering. But maybe a few percent efficiency is about the best we can do with relatively small temperature differences? I think radio isotope thermal generators are usually only a few percent efficient. It'

I thought it was interesting that they mention that 6061 aluminum sometimes contains scandium. I would have thought that 6061 was a more well-defined standard, that you couldn't add other things and still call it 6061. (I've done

I figure there must be a lot of things in sea water that might be valuable, if only you could concentrate them. Or in brines that are extracted from underground, like how some lithium is currently mined if I understand correctly.

The article links to another article with a lot more detail about the system: https://news.mit.edu/2022/portable-desalination-drinking-wat... 20 watt hours per liter of water seems to be the important number. I wonder

Yeah, I get the impression that's true. There's an electrochemical reaction that's going to take place whether you want it to or not, and you have to keep adding water until the reaction is finished. I kind of wonder if it w

I'm not sure what the inside of a car carrier looks like, but I think the idea isn't just that a little jiggle that causes the suspension to flex slightly is the concern but rather a car coming loose and falling on another car, or
