1) Agree that energy use is ethical. In fact, in so much as higher wealth and income is linked at the societal level to better outcomes such as longer life, lower crime, happier li…

This is true, especially for low frequency (high mass) inverters. The inverters that are covered here are overwhelmingly high frequency (low mass) inverters. We hope that they prac…

This isn't hundreds of separate sites that have to be hacked individually. This is fewer than 10 clouds with no security to speak of and the ability to push evil firmware to millio…

For the purposes of information security, the nameplate capacity is the correct number to consider for a very simple reason: we must defend as if hackers will pick the absolute wor…

I have a few pieces from loow.com (Wool backwards.) They are out of EU, and what I have from them, I like! (Not associated, just a satisfied customer that paid full price.)

I wash wool and silk using a ph balanced detergent with no protease. I use cold water, minimum spin, and a super long soak. Then I hang dry. It's more work to wash this way, but th…

Not sure if you count insects into your moral calculus, but silk farming only involves caterpillars and mulberry trees. It's warmer, softer, lighter, and way less smelly than plast…

Nothing is going to hit the price/warmness combo of plastic based fleeces, but I find the smelliness factor on synthetics to be worth paying extra for high quality natural fibers. …

We have some pretty good ideas about just how "lumpy" the explosion of the big bang should have been. And yes, the best theories in cosmology disagree with the recent observations …

The second one. This result confirms that the "hubble tension" is real. In other words, two methods for measuring the expansion of the universe disagree, but we can't figure out wh…

No. This confirms that the "hubble tension" is real. In other words, two methods for measuring the expansion of the universe disagree, but we can't figure out why and have new and …

I stopped reading at paragraph 4. What idiot is buying lead acid batteries in 2023 for solar storage systems? 4 12V 200AH deep cycle lead acid batteries cost $1552 on Amazon and ho…

+1 Ventile is an exception to the "rule" that "cotton kills" (in the cold). Especially great is for staying dry is double layered ventile, which is now free of flourine chemistry f…

Only if you want a battery that will die fast. Nissan made an insane decision early on to not heat or cool their batteries, and also not go with a battery chemistry that is resista…

The entire book falls apart because of two facts, both of which are in the book itself! "Hands down, solar is the only renewable resource capable of matching our current societal e…

Why isn't there more building? In most places that "need" rent control, it's because there are heavy restrictions on building. And rent control, all by itself, serves as a disincen…

The deep irony here is that you wrote "its not impossible for millions of people to have long term side effects from COVID." While it's clear from the rest of your post that you me…

Cheap space launch is the cause of, and the solution to, our light pollution issues. 50,000 satellites would be impossible to launch without the recent step change in the wholesale…

This is anti-vaxxer fud. If you look at places that have high vaccination numbers, oh wait, there aren't any. Israel is leading the world with only about 20% of their population ha…

The parent comment is a pack of memes straight out of a propaganda machine. https://blog.ucsusa.org/dave-reichmuth/new-data-show-electri... Lithium is a mine once, use forever reso…

The authors of this protocol made a valiant effort to defend against sybil attacks by requiring intersecting quorums. However, it's not clear to me that they succeeded. Specificall…

In many parts of the bay area (SF, Berkley, East Palo Alto), the incentives of large swaths of renters are neutralized on this issue through extremely severe rent control laws. Bet…

Homelessness in the USA in most places is an emotional or mental problem, but in some parts of the country, it's actually an affordability / NIMBYism / price control problem. For e…

The number one thing you worry about with a launch vehicle is not ISP, it's the tyranny of the rocket equation. We have tech with VERY high ISP (ion drives, for example), but we ca…

While the central observation of the article is vaguely interesting, what is more interesting perhaps is the slow and gradual pivots from Victorian moral signaling to modern moral …
