That would be the number of solar cells needed if the sun shown 24 hours a day, which it does not, and was 100% intensity for all those hours, which it does not. As such, you would easily need six fold more solar cells than calculated, which would emit 40 trillion watts of waste heat compared to the nuclear or coal's 6.66 trillion. That said, it is still a stupid calculation, as 40 trillion watts is still dwarfed by the heat being emitted by man's existing alterations to land use (black roads, dark roofs, farmland, etc) as evidenced by the large urban heat island effect, which has alone increased the planets temperature measurably.

^^^nonexistent evidence hmmm? Take a look at these 450 scientific papers skeptical of "man-made" global warming. Yup, 450. I will admit I have not read them all.http://www.populartechnology.net/2009/10/peer-reviewed-papers-supporting.html
10/31/2009 8:40:49 PM
^^would the waste heat increase, since before it was assuming 24 hour sun, and factoring that into the waste as well? it would seem that it would only increase the area over which solar cells would have to placed.[Edited on October 31, 2009 at 8:43 PM. Reason : .]

^^^ Nice. You are right, assuming fixed panel efficiency, although there were six times more of them, that would not change the waste heat calculation.

assuming even that your somewhat irrelevant points are true, does that invalidate his points in any way?and i'm not even sure whether he accounted for using only daylight hours or not. he doesn't say one way or the other.
11/1/2009 1:48:21 PM
11/1/2009 1:56:46 PM
are you fucking obtuse? of course they refute his points. He's trying to make the argument about the efficiency of solar cells vs. coal plants for their waste heat generation, and he comes right out the gates using a 3:1 heat to generation ratio for coal instead of 2:1. He uses solar efficiencies that are over 300% higher than real world situations, and he doesn't bother to address the storage issue. For energy storage, you have to pump water into a reservoir using transmission lines and pumping stations with their own losses, and then you lose water through evaporation and losses into the water table. Then you have to run the water back through a hydro generator that has it's own losses. With coal, you just burn it when you need it instead of having to store it. Even if you disregard the fact that pumped hydro isn't feasible to integrate with solar farms unless you build EHV transmission lines (345-765kV), the system from a purely mathematical stance isn't very efficient.
11/1/2009 2:00:57 PM
he also tries to make a point about land coverage needed on the planet for solar. He obviously understands nothing about base load vs. peak load, or else he would realize just how stupid his little map was. Also, he doesn't do anything to address that you can't build a solar field where the panels butt up to each other. You have to have room for maintenance for them. The man obviously wrote an article about something he has no understanding of. He may understand a little about climate, but he obviously doesn't understand jack shit about the power industry.
11/1/2009 2:05:55 PM
^^^ like I said before, I understand the scientific process, but if the UN, Al Gore, and the entire media industry up and picked a unifying theory of everything and started shoving it down everyone's throat, I wouldn't believe that crap either.
11/1/2009 4:39:25 PM
I'm not sure I understand. I wouldn't expect anyone to take the word of the UN, Al Gore, and the media about scientific matters either. But that's not where climate science originates.
11/1/2009 5:29:46 PM
^^^and you're not really addressing the point he was trying to refute. that levitt was saying that the fact that the solar panels are all black heat up the earth. the map was just to show how much of the earth's surface those panels would actually take up. that was the crux of what he was trying to say. he also made the point that aside from the initial impact of coal, it also has a lasting impact. but the point of the post was more about refuting that solar would cause warming (of any significant measure) just from its coverage over the earth.[Edited on November 1, 2009 at 5:49 PM. Reason : .]
11/1/2009 5:47:47 PM
I am addressing that point, over and over and over again. He uses badd numbers and failed logic over and over again to try to justify solar not being worse than coal, and I'm pointing out those instances. His comments regarding CO2 have no evidence or numbers to back them up, so he has to rely on a blanket statement of how evil CO2 is for global warming. He has no way to quantify any heating effect CO2 may or may not have, yet he uses this to try to validate why solar cells are better than coal plants even though they produce more waste heat.

11/1/2009 7:38:23 PM
the 4W/m^2 is a simple calculation straight out of thermodynamics. It's what he does with that number that doesn't add up. He assumes all our our energy consumption comes from coal, which it does not. Natural Gas and Petroleum plants both produce less CO2 for the same amount of energy. His CO2 reabsorption numbers have no explanation for where they came from, yet they make the largest impact on his overall calculations.he could have probably made his point by using real world numbers and shown that solar power has a slight advantage over coal, but he went out of his way to exaggerate the numbers to come up with his drastic difference.

What's ironic about that article is the author decries others for their arrogance only to be a pompous douchebag himself. I will give him props though for tossing in as many generalizations about environmentalism as I've seen crammed into one piece.

This thread has been going on for 26 pages, if truth and facts could enlighten you, you would be enlightened by now. I would take no less than Glenn Beck or Rush LImabaugh to start supporting climate change before we stop hearing idiots whine about some grand conspiracy by welfare climate scientists to trick people into believing that humans can affect our environment.
11/3/2009 2:39:41 PM
so, in short, you have no instances of fact. you are just blowing it out your ass. But, I suppose that you know more than this atmospheric scientist about atmospheric science, right?
11/3/2009 7:46:44 PM
^^Glenn Beck and Rush Limbaugh have too soft a position on global warming IMO, but thanks anyway. And I can't believe you said that, b/c I can say the same thing about you (26 pages of facts)[Edited on November 3, 2009 at 9:51 PM. Reason : though to be honest i don't really know their positions.]

ok, then what year would you pick to show there is no cooling trend at all evident? 2001?
11/3/2009 10:24:14 PM
http://www.cbsnews.com/stories/2009/10/26/tech/main5423035.shtmlRead it aloud if you have to. It isn't a matter of picking specific years. It is a matter of looking at moving 10-year averages and the overall decades-long trend of rising temperatures.
11/3/2009 10:53:01 PM
hahaha. So, you are resorting to CBS's NON PEER REVIEWED claim that a whopping four statisticians have disproved something. Really? and you claim that the deniers ignore science, lolif fox news did a similar thing to disprove something you would be howling about it. come on, dude.hell, the claim is that there has been cooling for seven years. how in the hell would you use a 10-year average to show that either way? We're looking at just seven years, for crying out loud!Hell, I'll even let you start from 2001, and the trend is STILL negative. And 2001 is a low year!wow, look at page 18 of this reporthttp://scienceandpublicpolicy.org/images/stories/papers/originals/sept_09_report.pdfIn short, the UN is using a number that is an order of magnitude higher for Atmospheric CO2 Residence time than what just about every other major researcher says it is. I wonder why they would do that...Talk about using consensus science, right? ]

^^Just when I thought you provided a legitimately peer-reviewed study, I found out about the journal that published it: http://en.wikipedia.org/wiki/Energy_and_EnvironmentThen I looked into the person who conducted the study, a Craig Loele of the National Council for Air and Stream Improvement, Inc. And I find this:http://www.sourcewatch.org/index.php?title=Craig_LoehleI read through the study, and thought it looked legit and was well-referenced. But after this, I'm skeptical of it. That's all I can say.By the way, you really should make the effort to research your sources before getting all huffy about the credibility of something.[Edited on November 4, 2009 at 3:17 AM.

Not by itself. It is possible he is taking advantage of the maths. If Ross Perot gave a dollar to some guy holding a "global warming = hoax" sign while Al Gore gave $1000 to his own foundation then his assertion would be both true and ridiculously irrelevant.

True, but it is well documented how much the US alone has spent on global warming studies. Billions and billions. Add all the money the UN spends on it...you get the point.

Non-random sample selections for a third run of the experiment, and an incredibly small sample-set at that.Then there's this gem:
