[edit] Megawatt output

The intro paragraph says that Solar One put out 10MW of power, but then later it says that the Solar Two modifications "allowed" it to put out 10MW; I'm guessing that means the initial output was somewhat less. Can someone with knowledge of this fix? -- nae'blis _(talk) 12:47, 19 June 2006 (UTC)

I agree, this ambiguity needs to be fixed. Do does the working fluid inconsistency. In Solar Two it says One used water, tbut the One subsection implies a different working fluid, specifically oil, as do other sources. --Belg4mit 05:29, 13 November 2007 (UTC)

Solar One used oil to store excess thermal energy in a big tank filled with rock. This allowed production of electricity at a derated condition after the sun went down. The initial design created superheated steam at 960 deg F and 1200 psi to run the turbine generator when the sun was up. I worked on this project in the late seventies doing boiler panel controller design and computer modeling of the boiler panels. I left the project before it was commissioned but, I heard from coworkers that Solar One, while rated at 10 MW, had produced up to 13 MW at times and ran well into the night from the thermal storage system. I do not know about the Solar two modifications.--The1Bear 13:04, 29 June 2006 (UTC)

It is possible that the project requirement for Solar Two was to prove a new working fluid (molten salt) while still producing 10 MW. It appears from other discussions that molten salt has greater heat storage capabilities, and that is what was being proved. Just a thought. The1Bear 18:45, 4 September 2007 (UTC)

[edit] Merging with power tower

solar one is a specific thing. it should not be merged to a more general idea. solar one/two/tres have plenty of information specific to itself ZyMOS 12:52, 16 August 2006 (UTC)

[edit] Solar One/Solar Two/Solar Tres

I understand the relation between solar one & two, but solar tres is in a completely different country. What is the relationship between these 3 projects? This needs to be mentioned in the introduction, I feel most readers will be confused as to what the relation with solar tres??? I have tried to find out what the relation is between them but have not found out, other than solar tres builds on the ideas from solar one and two. decrease789 12:50, 5 May 2007 (UTC)

"After the demonstration projects Solar One and Two, Solar Tres is the first commercial project of the Power Tower Technology. The Solar Tres consortium of Spanish, French, Czech Republic and US companies is promoting the 15-MW plant project with a large solar multiple of 3. The project, which has received a subsidy of 5 million Euro from the EC, makes use of the Solar Two technology tested in Barstow (California), but will be approximately three times the size. Solar Tres will make use of several advances in the molten salt technology since Solar Two was designed and built." [1] -- Johnfos 09:25, 8 May 2007 (UTC)

Also, what were the reasons behind the decommissioning of Solar Two?

[edit] Land Use

The article says solar uses less land than "...coal plants (including the amount of land required for mining and excavation of the coal)." I think this claim should have a reference- I have long been interested in such a comparison but have yet to find good data. BCC 12:14, 24 August 2007 (UTC)

[edit] Participants

Having been the writer/coordinator for the Westinghouse proposals for design and fabrication of a prototype low-cost heliostat for Solar One, my memory says that Arco was a major commercial sponsor of the project. If so, its role should be acknowledged. --NameThatWorks (talk) 00:01, 27 November 2007 (UTC)

[edit] Financial Information?

Hi, I have been trying to find out how much did the DoE put in for "The Solar Project." I can’t find it anywhere...Anybody? Thanks for your help. TheAsianGURU (talk) 22:53, 12 February 2008 (UTC)

I also want to know how much it cost to build the facility and what it cost for transmission lines to connect it to the grid. Johnfravolda (talk) 23:07, 23 May 2008 (UTC)

I found this in a 2006 article in Renewable Energy World: "Gilbert Cohen, Vice President of Engineering & Operations for Solargenix, said the project costs somewhere in the range of $220-250 million." Johnfravolda (talk) 23:19, 23 May 2008 (UTC)
