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 practiced great electrical engineering and layered multiple laye

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 millions of inverters worldwide, where in a few years at the

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 worst moment to attack the grid. That is the moment when the su

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 they last longer, never smell, and 100% silk and wool onl

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 plastic, so it doesn't need as much washing, so less en

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. Plastic clothing just ends up smelling gross and needs

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 highlighted in this article. On the other hand,

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 hold as much energy in practice as a 100AH 48V LFP battery whi

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 resistant to degradation in the heat. 10 years in, all those early

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 energy demand. Not only can it reach 18 TW, it can excee

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 disincentive to build. Why should I invest in a

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 meant the vaccines, you accidentally ended up m

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 price of launch. And even 5% of that number of space based

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 having undergone a full vaccination regimen, and it takes

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. Specifically, I worry that they are depending on people running no

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. Between rent control and Proposition 13,* the vast majority of

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 example, in the San Francisco Bay Area, there

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 can't use them until our vehicles hit space because

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 signaling, and whether modern moral signaling is more or les

Just to expand on one of the parent's points, Celiac is pretty rare, and affects under 1% of the population. However, Fructose Malabsorption is much less rare, and affects closer to 5% in the US. In spite of the name, Fructose Malabsor

This article is based on some incredibly bad estimates, and reaches an outrageously large conclusion. Let us assume that 100% of all mining rewards go to electricity (and none to buying mining equipment, paying employees, servers, or networ
