I don't have a dog in this fight. I'm just explaining why hydrogen will never be popular. For a new technology to be adopted, it has to be better than the status quo. Compared to current aircraft, hydrogen costs more, has new safe

Hydrogen fuel cells won't happen. There are too many downsides. Hydrogen must be stored as a compressed gas or as a deep cryogenic liquid. Either way such tanks are expensive, heavy, and create safety concerns. Hydrogen is a very perni

Ducted engines make less noise, which is handy for helipads in cities. They also increase thrust efficiency. If done right, the duct can contain any shrapnel if the fan blades come apart. The disadvantage of a duct is extra weight.

So because iOS apps can't run on Android phones, Apple is a monopoly and should be forced to use USB-C? I'm very confused by what you're trying to say. If apps not running on other OSes is enough to count as lock-in, then eve

And Apple doesn't run an app store on Android. Does that mean Android is also a monopoly? Heck, Sony doesn't run an app store on the Nintendo Switch. Does that mean Nintendo is a monopoly? We could play a similar game with streami

How can Apple have a "near monopoly" when Samsung sells 50% more phones than them?

I don't believe you. First, because the supply of civilian-owned machine guns was frozen in 1986[1], a mediocre full-auto gun starts at $10,000. Second, blanks won't cycle a gun designed to fire actual cartridges. You need a blank

Is that bit about the coating true? Wikipedia’s article on submarine pipelines says that the inside of petroleum pipelines are not coated. Pipelines are damaged due to accident or natural disaster, so it seems very odd to me that a pipeline

People buy Teslas primarily for two reasons: 1. The Supercharger network means you can take them on road trips without worrying. This isn't the case for other EVs which use the Electrify America charging network. 2. They're basica

It is extremely unlikely that a human being can hear a sound and move their foot within 100ms. Based on what we know of the brain and nervous system, it's most likely that anyone who reacts under 120ms has jumped the gun.[1] 1. https:

Such rifles are huge, heavy, expensive, and difficult to transport. I can't find a single instance of a .50 BMG rifle being used to murder someone in the US. Anti-gun groups like Violence Policy Center have one report of a .50 caliber

Coriolis deflection is a rounding error compared other sources of inaccuracy. In their press release[1] they said they didn't account for it: > Scott made the wind and elevation call of 1,092 MOA up and 17 MOA left. (In our original

That's not what was on kiwifarms. I've read that odious forum for years and their whole shtick is, "Look but don't touch." They do gather identifying information, and they do archive what people have said and done,

Three problems with that: 1. Every time you restrict what people are allowed to say or write, you are in effect restricting what people are allowed to hear or read. I read and listen to many things I disagree with. Sometimes I even find the

> EVs are much heavier than their equivalent ICE vehicles. This is not true. The Tesla Model 3 is the same weight as a BMW 3 series (~3,600-4,100lbs depending on trim level). Yes EVs carry a half ton of batteries, but they get rid of the

OK, apply that logic to the Bible and the Qur'an. Both endorse slavery. Both encourage believers to hate gays and to treat women as chattel. Countless followers have dedicated their lives to the tenets in these books, and in many cases

Freedom of speech isn't about speech. It's about hearing. There are people who want to read or listen to what others have to say, and often for reasons besides agreement with the author's statements. By silencing someone, you

The weirdest thing to me is that the Chinese had sky lanterns 2,300 years ago but they never scaled them up to hot air balloons. It took 2,000 years before Joseph-Michel Montgolfier saw some laundry billow as it dried above a fire, inspirin

Boom's original bet was that they could use better aerodynamics and materials to get supersonic speeds using existing engines. This saves a ton of time and money since you don't need to get the engines certified. The prototype use
