Making a second, third, or fourth set of manuals would have obtained substantial economies of scale whether in the 20th or 21st centuries. There was a time where PDF didn’t exist, there were no tools to create, let alone view or print manua

I've had this experience before. Believe it or not, I've also gotten takehomes which took multiple hours, involved some non-trivial data retrieval and management, and gotten rejected with less effort than it took them to prepare t

Get your T levels checked. Mine were way off (and still are). Exercising 5X a week is good, are you pushing hard, packing on more weight, or simply going through the motions? Focus on sleep hygiene. Try sleeping alone and in a pitch black s

Looks like a small dose is about as effective as a massive dose. What’s the downside of a quack doctor selling benzene-contaminated supplements for fat loss? I’m sure there’s a huge increase in cancer risk, but wouldn’t this cause a lot of

Yes and no. When you exercise, are you burning calories? Yes. Are you literally burning calories, as through combustion the way most people understand it? No. I guess a way to look at this would be akin to community trash fires that are sub

Excellent post, but we know very little about you. What do you bring to the table as a founder? Can you bring in money, can you sell? Is your pitch to YC all set to go, just need the validation of a tech cofounder on your team? Your idea, w

Now that’s just silly. Lots of things are more expensive than a nuclear reactor. Grid-tied batteries are now about $300/kWh. Capitalized over 25 years, that adds 3.3 cents to peak (11AM) solar prices, which themselves can go negative a

Than solar, ok. Than solar plus batteries, the numbers don't back you up on that (or no longer do).

Too late to edit, but I should qualify this: They claim 4000 tons per year, I did the math on 4000 tons per day. So ~3-4 acres of PV to power, not 1000 acres. To completely counteract the 37 billion tons per year produced worldwide, and do

We’ll run out of CO2 through the natural version of this process (weathering) long before the O2 encounters this problem. At that point all the plants die, still with plenty of O2 in the air. In other words, it’s the carbon content that’s m

1000 kWh/ton (found it on google): 166 kW/ton in a sunny place: 1000 square meters/ton in a sunny place: 4 million square meters = ~1000 acres of PV to power. One unit. Yeah, that’s going to happen. /s “We’re too ashamed

One reason, and not a very compelling one, is that trees in certain latitudes exacerbate global warming by absorbing more heat than naturally occurring grasses (which tend to be more reflective). In sum, it’s not better.

Removing ALL the CO2 in the atmosphere would be 1-2% the partial pressure of O2 in the atmosphere (barometric pressure where you live swings more than that). Of all the concerns, this one’s low on the list.

The trope is that public defenders should be and are funded equivalent to prosecutors’ offices. It’s less untrue in IL than in, say, Louisiana, but it’s still untrue. Prosecutors suffer a self-serving delusion: they’re born on third bas

After being railroaded by a dirty prosecutor, I’d like to dispel one trope: Brandolini’s law, also known as the bullshit asymmetry principle, states that it takes 10x the effort to dispel bullshit as it takes to make it. Therefore, every se

Calcium hydroxide is an extremely weak base in practice, and wouldn't oxidize carbonaceous materials if your life depended on it. But I could see it depositing in biochar as Calcium Oxide. A physical mixture, not a chemical reaction, i

Since Elsevier is hiding the meat in that journal article, I can only go off what I read, but it looks identically flawed. • Compressive strength of normal concrete: 25-50MPa • Compressive strength of their slag concrete with 2h CO2 added:

I doubt it's intentional. It's just the modern day equivalent of a perpetual motion machine or a "machine that makes water out of air" (dehumidifier). This particular subject matter area falls in a blind spot where elect
