<p>From The San Francisco Chronicle, we have the following on cost for this project:</p><p><a href="http://www.sfgate.com/cgi-bin/article.cgi?f=/n/a/2007/07/25/financial/f170204D70.DTL&amp;hw=solel&amp;sn=001&amp;sc=1000" target="_blank">http://www.sfgate.com/cgi-bin/article.cgi?f=/n/a/2007/07/25/financial/f170204D70.DTL&amp;hw=solel&amp;sn=001&amp;sc=1000</a></p><p>&quot;The Mojave Solar Park [stated elsewhere at 553 megawatts in size], estimated to cost $2 billion, would dwarf the largest solar plants operating today, which generate less than 100 megawatts of electricity.&quot;</p><p>This, if true, would translate to ~ $3.62 per watt of capacity.</p>

Concentrated Solar Power Plants of the Parabolic Trough type produce solar electricity at much lower costs as PV-Plants, due to their size in the multi MW-range and due to the more ore less simple technology. The collectors have a steel or aluminium structure on which mirrors and thermal reciever tubes are attached. However, the precicion of the space frames need to be very accurate. This has to be secured by an advanced&nbsp;quality control&nbsp;system.&nbsp;More information&nbsp;can be found on the website of the German Aerospace Center DLR:&nbsp;<a href="http://www.dlr.de/en/desktopdefault.aspx/tabid-618/1034_read-1412/" target="_blank">http://www.dlr.de/en/desktopdefault.aspx/tabid-618/1034_read-1412/</a><a href="http://www.dlr.de/en/Portaldata/1/Resources/kommunikation/publikationen/109_nachrichten/dlr-nari109_en_28-33.pdf" target="_blank"></a>

&nbsp;Does anyone here know how thermal solar compares with PV cost and efficiency?

553 MW over 6000 acres. That's 553,000 KW per 24,280,000 square meters
or .0228 KW per square meter, or 2.28% efficiency over the entire area. Granted the entire area is not completely covered with solar collectors. Still that sounds pretty sad compared with 14% efficiency photovoltaic modules. Someone double check my math to make sure I didn't shift a decimal place.
