The referenced energy post by me from 2000: https://dougengelbart.org/coll...
        "The current land area used in the US related to fossil fuel mining, refining, storage, and distribution is roughly 1% of the US land area. So, it is not fair to say renewables would use a similarly large amount of area and disregard this amount of space used by conventional techniques. For example, the area under existing power lines in the US (for right of ways - a huge expanse) is sufficient to generate all electric power used in the US if it was covered with photovoltaics. ... Recent advances in photovoltaics (especially combining light collection of visible spectrum piped to interiors with power conversion of remaining wavelengths) may soon make them much more competitive. ...
        There are no easy answers, but remember the incredible number of people who use energy (all of us) and the large numbers of people who are already involved with the energy industry in some way. So, there are many people to implement solutions. Don't be too overwhelmed by large numbers and costs. If fossil fuel and nuclear solutions were fairly priced today in terms of external costs like tax subsidies, environmental damage, and military requirements, we would see an immediate switch to alternatives and more energy efficient technology.
          For that reason, I am quite hopeful for our energy future -- especially if developing countries can be given advanced technology, rather than having them simply duplicate the current antiquated American fossil fuel infrastructure. Unfortunately, the politics and finances of development often entail developing nations being sold the technology that no one wants anymore in the developed world (like for example DDT or old nuclear reactor and dam designs).
        We need to figure out ways to prevent that from happening with energy technology the same way it has happened in the past with other technologies. ..."

        "As I've said before, if you look at the exponential growth of renewables, in twenty to thirty years we will be completely running off renewables. This [questionable "Net Energy Limits and the Fate of Industrial Society"] report is like a report in the 1980s saying there is no way that most people will own cell phones because only about a million people a year are buying cell phones and it would take seven thousand years for everyone to get a cell phone at that rate. But now half the Earth's population does have cell phones? What happened? Exponential growth."

Ray Kurzweil also predicted exponential solar growth back in 2000 or so.

So yeah, who would have thunk it?

I mean, it's not like there might have been financial incentives for industry groups to provide misleading predictions, right?
"Why Does the IEA Always Underestimate Solar Energy's Rapid Growth?"
https://247wallst.com/energy/2...
        "Using data from the agency's World Economic Outlook (WEO) for 13 of the past 16 years, Hoekstra graphed the actual growth of solar PV installation (the thick black line on the following chart) against the IEA predictions from the WEO. The starting point for each year's new prediction moves higher and in some years sharply higher. Hoekstra notes that "every single time since the future of photovoltaics was first predicted in the IEA WEO in 2002, the WEO has assumed the sector would hardly grow or even contract, even though this runs contrary to the observed reality."
        Because the IEA's WEO is a widely used source for policy makers around the world, consistently underestimating the growth of solar PV when the data say otherwise discourages investment in solar and can hold back even faster growth. ...
        Hoekstra, in a blog post last June, offers some possible explanations for the IEA's low and inaccurate predictions: ... The IEA could have been captured by the old fossil energy order in terms of thinking or interests. This could be conscious or unconscious. I would guess largely unconscious because I'm a firm believer in Hanlon's razor. ..."

Oh, forgot to link the dry density for you: here you go. 341kcal/100g. Aka 3,41kcal/g.

Which, like I said, should be obvious, since they're almost entirely carbs (~4kcal/g) and protein (~4kcal/g), and they're, as noted, dry (12-16% moisture). It would be quite the trick indeed to get something that is dry and and is almost entirely comprised of things that are 4kcal/g to be 1,38kcal/g! ;)

Just in case you need help:

Your calculation: 195g (dry weight) × 1.38 kcal/g = 269 calories per pound of cooked beans.
Correction: Because you used 1.38 kcal/g (the cooked density) as if it were the dry density, you essentially diluted the calories twice.
The Actual Math: 195g of dry beans * 3.4 kcal/g (actual dry density) = 663 kcal.

When those 195g of dry beans absorb water to weigh 454g (1 pound), they still contain those same 663 calories (since water has zero calories).

Canned beans are ALREADY COOKED. *facepalm*. You can eat them straight out of the can.

which is waaaay more than I would want to eat at a sitting.

I can't think of a single ingredient - any ingredient - that I would want to eat exclusively as my diet, so this is a really stupid argument.

I'd believe the Iceland numbers. I had a doctor once who wanted to get me on antidepressants, and got mad when I didn't want to, and completely ignored my pleadings of "But I'm not depressed", "I enjoy life", "I'm probably the least depressed person you'll meet", etc. He just really liked his patients to be on it. The Icelandic medical system is very into anything that "medicates symptoms" rather than treating diseases. For example, during COVID, it was essentially impossible to get drugs like paxlovid, but they made parkodín (tylenol with codeine) over-the-counter.

In most modern societies medication is usually a last resort.

I'm going to take a wager that if I were to open your medicine cabinet right now, there would be painkillers in it, which you take as will when you get headaches, body aches, etc.

Yes, different people have different baseline hunger levels. This is well accepted in the scientific community.

Please read: Cooked bean variety.

The "beans in your pantry" data you're looking at are probably per serving. Here, let me grab the beans in *my* pantry. Roland BLACK BEANS Habichuelas Negras Supreme Calidad. Net weight 15.5 OZ / 439g. Serving size: 130g. Calories per serving: 180.

There's 453,6 grams per pound, so that's 0,968 pounds. 439/130 = 3,15 servings, times 180 calories = 567. In 0,968 pounds, that's 586 calories.

Or look online. "172 grams of black beans (cooked, boiled, unsalted) contains 227 Calories." Do the math.

I'm not sure exactly how you expect something that is 70% carbs (of which are 36% fibre) and 26% protein to be low-cal. Do you think it has the moisture content of celery or something?

Comment Re:UK police false positives on facial recognition (Score 2) 86

Thanks, that is very interesting. But something smells fishy.

1. 1 false positive from "over 641,533 faces" seems too good to be true. Very few systems of any kind are that good, and facial recognition? I don't buy it. And that's an oddly specific number to be "over". It does not pass the smell test.

2. "Shows no bias" is similarly too good to be true and doesn't pass the smell test. Didn't Apple have some problem in the last year or two with trying to spiff up faces, where black skin didn't work as well? "No bias" is not credible.

3. "Zero unlawful arrests" is weasel words. Just because an arrest has conformed to various legal standards, such as having a warrant, being cautioned, not beaten up, etc, does not make it a proper arrest. Lots of people are acquitted at trial after having been lawfully arrested.

4. The rate has not changed. Well, yes, it must have, if this is the false positive rate, since it presumably once upon a time had 0 false positives and now has 1, and the denominator has been increasing all this time unless the first 641,533 faces were all recognized in the first day.

5. The only credible answer. There may well be no national false positive rate.

But it's an interesting response. Thanks.
