message: Concentrating Solar Power without Solar Cells is proven nonsence, since Concentrating Solar Power with Solar Cells is much better. The second competes with conventional power plants, the first can not. --95.222.227.5 (talk) 08:48, 20 July 2009 (UTC)
thread_title:  Description 

message: (Old: Revision as of 2009-09-03T11:01:42) 
The argument made seemed iffy, the one reference given linked to a "paper" apparently published by one guy in his own "online journal" (which has no other contributions than that author's articles). Within the paper, he even acknowledges a potential conflict of interest with the Desertec project. Also, concerning the IP that made the edit: The only other thing he/she worked on is the article about the guy in question. Seems reason enough to me to declare the source unreliable.

thread_title:  Reason for reverting critic section edit 

message: The study AQUA-CSP by the DLR Aqua-CSP shows that the Project enables the desalination of seawater and therefore will improve the access to  water instead of deteriorating it... I guess that should be included to answer the criticism in the critics section, especially the cooling of the turbine with fresh water would be very stupid an is in fact not intended, the reference project in morocco are cooled by large fans without using water...http://www.welt.de/die-welt/wirtschaft/article8628061/Desertec-Von-der-Vision-zur-Wirklichkeit.html
any objections?  —Preceding unsigned comment added by 84.143.104.159 (talk) 09:04, 19 October 2010 (UTC)
thread_title:  Claim to usage of water 

message: Currently in Masdar a 100 MW CSP-plant has been contracted, this would not happen, if the technology would have failed to prove feasibility there, right? And I cannot find any original references to the claims Hermann Scheer is posing... Opposed to his claims, CSP Plants in the Mojave Desert have proven since 1981, that they function very well in deserts... The claim, that only PV would be used now in Masdar now is wrong, as can be seen from the contracted csp plant... PV was part of Masdar from the beginning, but it does not exclude CSP... Hermann Scheer certainly is biased because of his concept of decentralized renewable energy production... anyways, some original references to the Masdar issue would be helpful for discussion, if anyone could contribute them...Beachie1 (talk) 15:56, 2 November 2010 (UTC)
replies: text: There is matching reference (interview with Hermann Scheer by correspondent :de:Stefan Schulze-Hausmann, TV contributions "Zukunftsstadt Masdar" and "Desertec", :de:nano (Sendung), 3sat, 10. May 2010).  Due to national regulations the broadcasted television interviews need to be taken off the web after a few weeks. I guess that I do still have the recording (dvb-s mpeg2) somewhere - but you need to understand a fair bit of German if you want to check the reference yourself. Let me assure you that the information was given in that way, on the other hand the world moves on and the technology might have changed in the meantime (personally I have heard of new coatings that are more resistant to sand winds but I had not seen a definite reference on that so far). Guidod (talk) 09:24, 3 November 2010 (UTC)

text: The Masdar information was not directly in the interview but the whole TV report had a section about Masdar city - the interview was right following the report thereby asking Scheer about the what and why. Given that he is an expert, you know (... has been an expert at the time, he died a couple of weeks ago) Guidod (talk) 19:34, 3 November 2010 (UTC)

text: Sorry that I do not have time to work on this. Sometimes the technology changes faster than a Wikipedia article can evolve. There was just a TV report covering the results of Novatec Biosol "PE 1" being good enough that they are in the process of constructing a 30 MW "PE 2" to be finished in April 2012. The interesting piece was that they use Linear Fresnel Reflectors which are actually flat. The TV report did highlight the sand problem and they showed a small robot with brushes running along the lines of LFRs panels. They used water to be heated in the absorber which is later reused by simple air cooling. Along with a resistant reflector coating this seems to be a viable solution to the sand problem as well as the water supply problem - I can even imagine that these flat panels could be abraded from time to time. In any case, the technology problems for Desertec can be well solved within the next two years. Guidod (talk) 16:19, 13 November 2010 (UTC)
replies: text:  is that TV report somehow accessible? WOuld love to see it :) Beachie1 (talk) 12:01, 15 November 2010 (UTC)
replies: text:  It was aired just a few days ago so it should be accessible in the 3sat.de/nano mediathek as a web stream. Look for http://www.3sat.de/page/?scsrc=2&date=2010-11-10&division=nano&cx=60 "Fresnel-Kraftwerk - Sandfeste Solarkraft" (Fresnel-powerplant - sand-resistant solar power).

thread_title:  Claim of Hermann Scheer 

message: "Transmitting energy over long distances has been criticized[who?], with questions raised over the cost of cabling compared to energy generation, and over electricity losses. However, the study and current operating technology show that electricity losses using High-voltage direct current transmission amount to only 3% per 1,000 km (25% per 10,000 km).[65]"
First, I don't see the need to reply to the criticism like is done here. Secondly, for an expert, it would be obvious that the replier here does not quite grasp the complexity of this issue. Having the technology to build adequate transmissions lines is not the same as actually having them in place. It's a bit like someone saying that fuel consumption of cars is a problem, an someone replying "No, there are many solar powered cars". Therefore, I don't think the second line belongs there. It could possibly be moved to some separate technology section.130.243.207.18 (talk) 00:09, 20 September 2012 (UTC)
thread_title:  Transmission 

message: How can Dii GmbH have conceptualized a concept that existed for years before it was set up in 2009? There is lots of detail in the following TREC and DLR section below about the extensive research that had already been undertaken by different organisations. It seems to me that all the major points - the abundance of solar power in the desert, harnessing renewable energy where it is most abundant, regional power markets, power for MENA, export of excess power to Europe - were already in place. You could say Dii have provided an update or a reinterpretation but the present article.  — Preceding unsigned comment added by Nuncledarn (talk • contribs) 16:02, 18 September 2012 (UTC)
