Oh please. It's the left that wants to build the telescope. When was the last time you heard about right-wingers giving a shit about astronomy or basic science unless there's profit involved? There's no profit in astronomy.

As someone above stated, this is a fight between the pro-science left and the SJW wacky-left. And unfortunately it looks like the wacky-left is winning.

-1 Stupid. This is basic history.

The Roman Empire (at least the western half) collapsed in the 400s, as western Europe turned to feudalism. The RCC managed to hang on to some power, but it was nothing at all like the political power enjoyed by the Roman Empire (and before it, the Republic) before. Technology was completely lost and forgotten as people abandoned specialized trades to go work in fields as serfs. This was called "the Dark Ages", mainly because education and literacy vanished and no one wrote stuff down any more. Eventually, the various feudal lords consolidated their power again into duchies and nation-states, and these were largely under the control of the Holy Roman Empire, but the HRE was *not* an extension of the actual Roman Empire before it, nor was it even much of an "empire" as it did not have very consolidated power. And the HRE fell apart eventually too. The modern RCC has zero political power, and hasn't had any for centuries.

Aside from this, the eastern Roman Empire continued for an additional 1000 years in Constantinople, with their own church, now known as the Greek Orthodox church.

The power density of a typical battery is very poor

Totally wrong. You even admit you're wrong: you linked to the Wikipedia article for "energy density", and then call it "power density".

Go study the difference between energy and power and come back when you've figured it out.

There are a *crapload* of SJW's floating around lately who are very savvy politically, but don't know jack shit about science.

Yet, you're the moron who doesn't know the difference between energy and power. That's science 101 right there.

Turbines have horrible efficiency at small sizes. There's a reason that small airplanes and helicopters all use piston engines instead of turbines. There are some amateur builders who build small turbine-powered helicopters but their fuel efficiency is poor compared to piston-engined versions.

Whose ideas *are* "original"? I can't think of a single major commercial innovation which was really an original idea. Apple's iPhone? Nope, smartphones were around before. The early cellphones? Nope, not original at all: Maxwell Smart had one in his shoe in the 60s. Personal computers? Nope, they were envisioned in the 60s too. The Wright Brothers airplane? Nope, not original: people dreamed of airplanes long before that.

No one (except ignorant people maybe) ever said that Musk came up with truly original ideas. Like successful industrialists before him, his strength is taking ideas and actually bringing them to market.

Honestly, do you think anyone really thought that rockets to LEO were an original idea of his, when others have been doing that for decades? Or that electric cars are an original idea of his? People have been building electric cars for over a century now, or have you forgotten the GM EV1?

This is either a seriously stupid comment, or a great example of a strawman.

There's one strong Android player today. But there could have been two strong players, one of them being Nokia, had they tried entering that market. All those other Android players didn't have the reputation and cachet that Nokia had. Everyone always raved about the hardware quality on Nokias, even with their Lumias running Windows Phone, they just didn't like the software. No, it might not have been a slam-dunk success, it might not have ended well, but those are suppositions. I think it would have turned out a lot better than how it really did with WP. Nokia had a brand cachet that no one smartphone maker had, not even Samsung, which would have been incredibly valuable in western nations, especially Europe. But they didn't offer Android so everyone dumped them and went to various Asian phone makers (Samsung, HTC, LG, Sony) because those companies gave them what they wanted.

The second one is the device is dropping voltage and consuming power. In standard USB with 500mA at 5V, if the MOSFET takes 1V, that's half a watt of power you're losing in the transistor. (And really, you just use a diode). USB-C with up to 100W, you're looking at losing a lot of power in your reverse protection components.

100% wrong.

The MOSFET is not a diode. Diodes DO cause a 0.6-1V drop. That's why they use a MOSFET instead here in applications where a diode drop is too much. The MOSFET only drops as much as its internal Ron on-resistance allows. For a high-grade MOSFET, that can be in the single milliohms, so it's effectively a dead short. Cheapo MOSFETs are still in the low tens of milliohms. So with 3A of power, that's 1/4W with a crappy 30mohm MOSFET, or 72mW with one with a 8mohm on-resistance. The only reason you'd leave this out if reverse polarity is at all possible is cheapness.

Comment Re:Social Justice Twitter (Score -1) 98

Typical SJWNPAT (my acronym for SJW Normal Person Anti-Terrorist), all Twitter is doing is censoring people for criticizing Ethics in Western society. Sure, some people have claimed in ISIL's name to have murdered a few people here and there, but first of all THOSE people they supposedly "murdered" are professional victims and their claims of being murdered are highly suspect no matter how many videos we produced of them being beheaded and threads on /r/WesternSocietyInAction you can point at where every laughed at the Beta Cuck Infidels. And secondly, just because they said they were ISIS doesn't mean they were, I mean, it's a hashtag, you can't police that. You can't blame some guy on Twitter who is just concerned with Ethics and sends a few rape threats to Hillary Clinton THAT ARE CLEARLY NOT SERIOUS with some other guy who murders people because that's totally unfair.
