Offshore wind is one of the most hideously expensive methods of power generation. Here is a comparison of the levelized cost of generated electricity, in US cents per kWh, for various generating methods, projected for 2020:
These cost figures from the Energy Information Administration include all factors: amortization of the original capital investment, continuing investments, operating and maintenance expenses, fuel expenditures if any, etc. Only the cost of generation is accounted; not the cost of transmission. They are cost figures, so a business would have to mark them up to cover profit.
I don't claim that offshore wind is never worth pursuing in any situation, just that it is in general an extremely poor choice. For powering a remote island, if there is good reason why onshore wind is not practical, or is undesirable for some external reason (such as lack of available space, or protectioon of natural beauty of a resort area).
Then it's a good thing there is something of which you appear to be unaware: SMALL CLAIMS COURT, which presents a very low barrier to holding these pricks to account.
If a car maker wants to say they won't warranty the engine if you hang fuzzy dice on the mirror, they can - as long as that's clearly spelled out in the warranty terms
You're full of shit. Sure, they can SAY it, and HELL NO, they can't weasel out of liability just by making up any kind of blatantly false fairy tale.
Get the hell over it. Teslas are NOT goddam self-driving, full stop, end of story. If they advertised self-driving, that was a massive boo-boo in the translation. Autopilot, that's something else altogether; sure, they have an autopilot.
Almost all electric cars have a gearbox. ALL those of which I am aware and which are serious transportation do. The difference is that usually, one or two gear ratios are enough for electric. The norm for internal combustion cars is 4 to 6, occasionally more (plus reverse).
Now, I readily admit that it is POSSIBLE to make a practical electric car which has no gearbox. It can be done using low speed individual wheel motors.
A battery has a cycle life - take that number times the capacity of the battery and you get the total amount of power the batter will deliver.
Incorrect. The units of capacity are ENERGY, not power. Energy times a constant is still energy. The cycle life of a battery is analogous to how many times you can fill a fuel tank. If you could only fill a car's fuel tank a few hundred times before you had to replace it, and if your fuel tank cost $8000-16,000 instead of $100, THEN you would have a situation analogous to the electric car.
I'm not so sure you should dismiss the Chinese as mere copiers. That's a little facile. The Japanese used to be belittled as mere copiers, too, but that was always an unfair generalization. The Mitsubishi A6M "Zero" fighter was not a copy of anything. It was far superior to anything that any other Navy had. They developed a vastly superior aluminum alloy, 7075, in the middle of World War II. They had the only submarine Aircraft Carriers (I-400 class) in the world, and they were also the largest submarines in the world. They had by far the best torpedoes in the world. The MXY7 Ohka was a devastating rocket-powered, human-guided anti-ship missile.
Yes, China and Japan have in history (up to very recent history in the case of China) copied, and stolen, plenty of stuff from the US. But they also have made great native achievements.
Who already has the world's only anti-ship ballistic[*] missile? Gee... China - the DF-21D. It can't be copied from the US, because we don't have anything like that.
[*] The "ballistic" part is a misnomer, because the missile has terminal maneuvering. But that is always how it is referred to as.
I think the point is that merely possessing the ability, and demonstrating it on isolated demand, does not mean they will necessarily USE IT consistently.
I don't have any trouble whatsoever believing it. These are the same idiots who play with food and drink, apply makeup, shave, send and receive text messages, stare at printed papers, ogle girls in bikinis, and do all manner of other reckless things while their sole attention should be on driving.
Oh, you are SO clever. The fact is, Tesla blames identifiably STUPID and RECKLESS driver behavior. The drivers are PRETENDING there is blame on Tesla's part. Do you see the difference there, or is the difference too hard to grasp?
Tesla's autopilot is a failed concept. It's not that it's no good technically. It's that drivers will NEVER be ready and willing to use it properly. The problem is, it would be a little late for them to admit failure now and disable it. It would open Pandora's box of litigation over past problems, and do way too much damage to their reputation. I don't know what they can do. I know what they SHOULD have done in the beginning. Don't pretend you can paper over impossible situations.
You have no idea what an autopilot's function and limitations are, so quit pretending that you do. FYI, an autopilot will merrily fly your plane into a brick wall if there is a brick wall at your altitude on the course you tell it to steer.
God help us from people who make up their own conception of what terms mean. It;s no crime to be ignorant, but pretending you know it all when you know nothing about the subject is just presumptuous and silly.
You're the one who is completely full of unsupported bullshit. EVERY car gets better fuel efficiency at 55 than the same car at 80. The force or thrust required to overcome rolling friction is constant with speed, and the force or thrust required to overcome air resistance rises proportionally to the SQUARE of the speed. That means that the POWER (P=f times v) to overcome rolling friction rises proportionally to the speed, and the power required to overcome air resistance rises proportionally to the CUBE of the speed. Finally, the energy required to move a given DISTANCE (E = P times t) varies in exactly the same ratio as the first relationship.
The federal constitution reserves powers not granted to the PEOPLE. Powers specifically granted go to either the states or the federal government, but that does not mean that the states get anything not granted.
You couldn't be more wrong. The US Constitution: 1) Guarantees certain defined rights to all the people in every state. 2) Grants certain defined powers to the Federal Government.
All other power, without further limit, devolves to the individual states. Each of them is sovereign, and can write anything into its own constitution, subject only to the above two specific limitations.
Hah, hah, hah. Capitalism is ALL ABOUT privilege, arrogance, bribery, and corruption - gee golly, same situation as Communism ends up, isn't it? Because it's all about HUMAN FAILINGS. As long as humans are in charge, you're shit out of luck.
I think you meant free enterprise. True free enterprise is about as rare as true communism.

Offshore wind is one of the most hideously expensive methods of power generation. Here is a comparison of the levelized cost of generated electricity, in US cents per kWh, for various generating methods, projected for 2020:
Natural gas combustion: 6.9-15.6
Coal combustion: 8.7-16.0
"Advanced nuclear": 9.2-10.1
Hydro: 6.9-11.9
Geothermal: 4.4-5.2
Photovoltaic: 9.8-19.3
Concentrated solar heating: 17.4-38.3
Onshore wind: 6.6-8.2
Offshore wind: 17.0-27.0
These cost figures from the Energy Information Administration include all factors: amortization of the original capital investment, continuing investments, operating and maintenance expenses, fuel expenditures if any, etc. Only the cost of generation is accounted; not the cost of transmission.

A megawatt is a unit of POWER, not ENERGY. 30 MW is about 3% the power output of a typical nuclear or fossil-fuel power plant.
Then it's a good thing there is something of which you appear to be unaware: SMALL CLAIMS COURT, which presents a very low barrier to holding these pricks to account.
You're full of shit. Sure, they can SAY it, and HELL NO, they can't weasel out of liability just by making up any kind of blatantly false fairy tale.
No, it fucking doesn't mean that. You are lying. Cut the shit.
Get the hell over it. Teslas are NOT goddam self-driving, full stop, end of story. If they advertised self-driving, that was a massive boo-boo in the translation. Autopilot, that's something else altogether; sure, they have an autopilot.
See, I think there needs to be a -1: too stupid to realize how stupid attempts at sarcasm almost always are.
Off by 100 times? That makes quite a difference.
No it isn't. Wind and solar costs considerably more than coal and gas. The "fuel" may be free, but the amortization is anything but free.
Oh boy, where do I get that? Oh ... I can't ...

There was no "Pacific Theater" AFTER World War II. Sheesh. Certainly not 1958-1971.
