> If those panels cost more than $82 / mo extra in the mortgage, then it doesn't fly
I just ran a calculator on my 20-yr mortgage. For $55 a month I can get $10000 in cash. At current prices, that would buy me about 5 to 6 kW of panels with microinverters, or as much as 8 kW if I go with strings.
I currently have 2.6 kW and that supplies about 1/3rd of my total yearly power use. So that $10000 would definitely be enough to turn it to zero.
So, I guess (A) you'll be rushing out to do this now, right? Or, more likely, (B) just come up with another excuse not to? Let's see

Yeah, plan B it is
> which is why I have been saying for years we need a "people's car/truck" that runs on diesel
So the thing is, when you refine a barrel of oil you're still going to get the same amount of gas and diesel out of it.
So if we all switch to diesel in order to improve things, the price of diesel skyrockets while the price of gas plummets.
So we wouldn't buy the diesel.
> Gasoline is actually about the same price adjusted for inflation. A little higher but only about 50%
50% is "about the same price" and "a little higher"?
I think the common man would call that "a lot higher" and "not the same price at all"
"The US Department of Energy estimates that a new photovoltaic power plant entering service in 2017 will runs about $157/MWh in total levelized system costs (in 2010 dollar terms)."
Ahh, the famous DOE report. The numbers in question were from the 2008 time frame. Prices since then have fallen 4-fold.
I bought my SolarWorld 230W panels in 2010 for $2.30 a watt. Today I can buy 270W versions for $1 a watt. I can get Chinese A-brands, like Trina, for about $0.75.
The price of power from PV is directly related to system cost and pretty much nothing else. Total installed costs have fallen from about $8 a watt to about $3 a watt. Factor that in, and the fact that the numbers in the DoE report are from even earlier, and you're looking at a 4 to 5-fold decrease in system prices.
When you factor that in, power from PV is about 12 to 25 cents, which is *extremely* competitive with other peaking sources like NG.
> Why do you deserve it more than your grandchildren
This is the real issue, IMHO.
We're demanding faster, faster, FASTER, cheaper, cheaper, CHEAPER. So now *we* have all the cheap fuel and metals, and they won't 50 years from now.
The good news is that our kids are smarter than we are (Fitt's Law), so I'm not really that worried.
"This question is easier to ask when you're making well-above-average computer-programmer-level salaries and quadrupling the price of electricity and fuel (or something)"
You know, for someone that's declaiming people who work with math, you seem afraid to, you know, run the numbers.
I just quoted out a PV system for a customer who's tired of his ever-rising electricity bill. His current price, all in, is 13.2 cents for a kWh. That the price today, if you factor in historical price increases, you add 3% per year. I should point out that that is *below* the price of inflation - energy, like most commodities, is getting cheaper and cheaper. Anyway, when you add that in the cost over 20 years averages out to 17.6 cents/kWh.
I sized out his system so his net yearly consumption would be just a little over zero. That came to $1.15 a watt. If we add $1/W for installation, which is about the going rate, then you're looking at total installed costs under $2.50 a watt.
If you plug that number into NREL's LCOE calculation (Google "LCOE calculator") that comes to about 16 cents/kWh. So in other words, it's cheaper for him to buy solar panels than buy power from the grid.
Don't believe me? Run the numbers yourself. Here's a step-by-step guide:
Systems costs in Ontario are higher due to "local content" rules and some specifics of the metering we're forced to use, and the systems are limited to only 10 kW (instead of 50 as in the example above) so the scaling factors don't work out as well. But even then, systems are going in right now for $3.20, end-to-end.
"But if you compare the first couple of season of both shows to recent episodes there really is no comparison as it was MUCH funnier and written better in those first seasons than it is now"
Proof in pudding; a few smart one-liners from the originals:
"First one, then the other"
"These balls are making me testy"
If you're ever looking for a demonstration that the original writers are smarter than you, consider the last few seconds of Parabox.
I watched some of the new seasons when they appeared on NetFlix. I made it through a few episodes before I gave up. Everything that made the originals funny was missing.
"If the patent had been more narrowly-defined and was about a unique and easily-recognizable design, none of this would have happened"
But that is precisely what is happening. I don't see Apple suing Nokia over the Lumia 520, yet that phone has all of the same features being discussed - rounded corners, smoothed back, etc.
No one could claim with a straight face that anyone would ever confuse a Lumia for an iPhone. Could you make the same claim for the original Galaxy S?
It seems to me that everyone that's actually involved in the case has no problem understanding what "distinctive" means, and conversely, when there is the suspicion of design infringement. The only comprehension issues appear to be here in the peanut galleries. Yet the accusations of known-nothingness are always pointed in the opposite direction.
We *sell* panels with cells over 20%. You can buy them anywhere. *Panel* efficiency is lower, typically 16 to 16.5%. That's because of the space between the cells, reflection off the glass, wiring losses, etc.
Panels are widely selling for about 70 cents a watt. Racking, inverter and wiring adds about the same amount. So even if we reduce the price of the panel by half, that will have an increasingly small effect on the installed cost. However, wiring and racking varies with the area of the system, so any decrease in arial efficiency increases the cost of these items.
It is going to be *very very* difficult for any low-effiency product to make any headway in the current market unless it eliminates racking and wiring. Solar shingles may be able to do this, but I have yet to see them get anywhere near the price points of conventional systems.
"She basically shut down the UK's manufacturing industry and moved us over to a service industry economy"
Why do people imply this is a bad thing?
Imagine I make a widget that costs me $100 to build and I sell for $120.
Now imagine I charge people $120 to ride a roller coaster for a day, which costs me $100 to run.
Economically, the effect of these two is identical.
But wait, you say, someone has to build *something*, right?
Why? It is entirely possible to run a complete economy without any physical goods. Ask the tourism business.
And it is clear that we will gladly pay for virtual goods as much as physical - ask the cable TV business.
So I'm all for a switch to services and virtual goods.
"Then tell me how the capacity factor of nuclear power compares on those days."
Capacity factor of nuclear: ~ 85%
Capacity factor of PV: ~ 20%
Price of peak power in the summer: ~ 35 cents
Price of base load: ~ 3 cents
35 / 3 ~= 12
85/20 ~= 4
12 >> 4
But don't believe me, do the math yourself. Here: http://www.nrel.gov/analysis/tech_lcoe.html
Vogel is $7.25/Watt, discount is about 6.5, capacity is about 85
Large PV is about $3/Watt, discount is about 4.5, capacity is about 20, fuel and heating is both zero
"although some good research still comes out of it"
What? A little stellar astrophysics and dense matter stuff, but we could get that same data other ways. Everything else is weapons related, and as NIF has demonstrated pretty clearly, wrong.
"Programs more directed at specifically producing fusion power concepts, like HiPER,"
I wrote the Wiki article on HiPER so I'm pretty familiar with it. It has no possibility of ever being an economical power producing device. The fast ignition process improves Q by about an order of magnitude, and so would solid-state lasers. So that's two orders of magnitude. We are five orders away from a practical Q. No one has any idea how to bridge that gap.
Note that Mike Dunne, who almost single-handedly ran HiPER (and a cool guy generally) left the project and is now at NIF. I believe HiPER is basically dead, but I haven't heard much one way or the other recently.
"I find Focus Fusion or some other non-billion-budget projects much more appealing"
Certainly, except they don't work, and can't.
You *are* aware of Rider's work on non-equilibrium plasmas, right? Here, read the last sentence of this abstract
It's been out for almost two decades and no one's come up with an answer. He had a follow-up paper that expanded the same principles to a much wider set of potential designs. Almost all of them won't work - not "it will be hard", WON'T.
Let's all show human CONCERN for REVERAND MOON's legal difficulties!!
