Exactly my point.
I go a bit further:
The more wind power you have over a larger area the more stable the overall "supply" of wind is.
The answer is:
You have already sunk the costs in building the windmills.
At that point, the choice is:
1) continue operating and pay the minimal maintenance costs
or
2) spend a lot of money building new coal/gas plants
The real question is what will happen in 30 years when the windmills reach the end of their useful lives.
The hard part for wind power is building it in the first place.
Well, bear in mind as scott pointed out a long time ago (economist who actually studies oil industry), the limiting factor for fuel used to be refinery capacity.
That limits conversion of fuels to what the market demands, and that means that a strict BTU content measurement won't always match up.
There has been a subtle change in mindset/paradigm in people who write a lot about this topic to start viewing fuels by actual energy content, because of the realisation that sources of energy are becoming increasingly interchangable.
One has to remember that when one looks at gas following the price of oil.
If oil goes up, then things made from oil go up. Demand then shifts from oil to alternatives, such as gas, until a new supply/demand equilibrium is approached. There is a certain amount of investor speculation involved too.
Since oil is THE dominant energy source for humanity currently, the weighted average cost of a unit of energy is highly dependent on oil.
Bull , if you want a larger capacitance you just add plates in parallel.Yes, I know. I didn't think Fuzzy would be able to find them. Besides, I also said capacitors are normally rated in microfarads and below. They finally broke the 1 farad point about 20 years ago if I recall correctly. Still, their capacity falls short of batteries, and they fall short of retaining power for any decent time. Have to convert to DC, then back to AC also. When you consider they are halved in value for series, and DC transmission are normally something like 300KV+... Did a quick check, the best out there by Wiki is 20 Wh/Kg. maybe a little better now, but it won't be much.
And of course you did not think I would find it. You did not know they existed because they are not a part you change in the machines you work on.
OK smartypants.
Show me a 300,000 Volt 1 farad capacitor.
Remember, you have to put capacitors in series to increase the voltage. Series capacitors decrease their capacitance. Therefor, if you have to put in series 10,000 capacitors to have a 300,000 volt breakdown voltage, then you have to also have 10,000 of these strings in parallel to maintain the capacitance. That's a total of 100,000,000 capacitors at 1 farad each, or 100,000 of them if they are 1,000 farad capacitors. Another problem, i think this design stops at 3 volts breakdown. Not 30.

I do not have to show . There have been 1F capacitors in car stereos alonefor decades.
I also said in parallel not series. You can try and throw that in there to make a point but I guess its beyond you to conceive of a circuit of only parallel capacitors You really do not know . Not all capacitors are used to build up voltage to start an electric motor like you are used to working on.
You put them in parallel and then consider sigma-V = 0. Seriously how do you figure they make the larger capacitors? You think they just make huge plates? God you are clueless.
Go change some parts.
it's always amusing to see how threads spin out of control in here.
LOL...
Again, you prove you are full of it. ∑ V doesn't matter. You risk turning your capacitors into bombs if you exceed their rated voltage.
Since you like playing quiz show. How do you think they make the 100F capacitors? I know that you only understand the specs on the parts you are changing but come on.
When you split the circuit the voltage going into each capacitor in parallel is equal. So what does that mean for the voltage on each capacitor?

True. Voltage is still the same. But you have to put capacitors in series to increase their breakdown voltage, which decreases capacitance.
I enjoy a good technical (read: nerd) discussion.
No its true and thus sigma-v is key.
When you put them in parallel the voltage and current in are the same as the voltage and current out. In essence, it is the same as a single capacitor with a larger surface area and that is what you would see if you actually opened up the cylinders that you change out and again capacitors have many more uses than the starters that you are used to working on.
If you had even a rudimentary understanding of the physics involved you would know this.
You quite obviously know nothing about signals.
This clearly demonstrates how your knowledge is a tiny box.
Ask anyone who has studied electronics.
You are flat out wrong. All capacitors also have a rated voltage. You cannot use small voltage capacitors with high voltage.
zeez guys, get a classroom.
I'm trying to school him, but he's too dumb to understand that he doesn't understand.
Kinda like how you schooled me on temperature inversions causing sudden wind stoppage over large areas?
I don't know if that was the actual cause, it is an educated guess because of the geographical features of where I lived. I simply know that the winds were rather erratic, and could suddenly stop where I lived. Weather of not it is cause by the inversion over the mountain range is uncertain. I do know the changing wins is a fact there however.
Prove me wrong or can it.
WC, I don't think you can claim something then expect your opposition to have to prove it. Technically, the burden of proof is on you to provide empirical data.
Some things are difficult to prove. If he is so certain that something he never witnessed cannot happen, then what is that based on?
How many things in life have you witnessed, but don't know how to prove what you witnessed?
He is calling me a liar. For that, I demand he put up or shut up.
Bluster gets you nowhere. Lets get back to capacitors in parallel and why you brought up voltage. You only bring up putting capacitors in series but we are not talking about that.
We are talking about why on Earth you would think that 1F capacitors are some sort of new technology.
Basically all you do is bring up whats on the schematics of the machines you change parts on.
Well, you made the claim, and right now it's your word against his. If you produce evidence, he'd have to rebut it.
That's kinda the point though. If I tell you I saw an elephant jump 2 feet into the air, but have no proof, then it's just on my credibility. And on the internet, personal credibility doesn't go very far.
He's not calling you a liar, per se. He can believe that you've felt the wind die down suddenly, while also believing that you are wrong about that affecting overall wind patterns/energy/etc.
I don't think anyone's saying that your personal experience is invalid WC, just that it doesn't do alot for your overall argument. (Additionally, I think Manny might even concede that windmills aren't an efficient usage of resources in those mountainous areas, and would be better, say, on the East Coast.)
Yup the whole prove me wrong or IOW prove a negative is literally impossible. You can always question causality.
I can admit that I do not know about meteorology. WC sounds like his narcissism cannot withstand ever being wrong.
Hey fuzzy...
Check out this:
CapacitorsIf that's not enough, the facts about capacitors are readily available. If you don't know how to google, let me know. I'll find more for you.Breakdown voltage
When using a capacitor, you must pay attention to the maximum voltage which can be used. This is the "breakdown voltage." The breakdown voltage depends on the kind of capacitor being used. You must be especially careful with electrolytic capacitors because the breakdown voltage is comparatively low. The breakdown voltage of electrolytic capacitors is displayed as Working Voltage.
The breakdown voltage is the voltage that when exceeded will cause the dielectric (insulator) inside the capacitor to break down and conduct. When this happens, the failure can be catastrophic.
