message: I edited the obvious mistake, namely the 179 / 310 = 1.73 Euro. I'd like the original editor to fix the paragraph and clearly explain the assumptions he's making. Where does the division by 11.65 come from? If the lifetime is 25 years, and you repay the cost, C, in C/25 chunks with 7% interest on the remaining balance, then the largest(first) yearly payment you make is C/25 + .07*C. So, if 179 million KWh come out every year, you have to charge (1/25+.07)(C/179) = (.11)(1.73) = .19 Euros/KWh. If you consider the average yearly principal+interest payment, then you have (13*.07+1)/25*(C/179) = .13 Euros/KWh. An explanation of the financing assumptions the original editor used would be appreciated or I really think a more involved/useful analysis should replace that paragraph (or some citation to a study that calculated the levelized cost already).

thread_title: Removed this section

message: This page is unclear in its layout: is it aiming to classify technologies by their application (process heat etc) or by the original method of capturing the energy (flat plate, concentrators, tracking, non-tracking etc). A significant rewrite is required to make the different technologies clearer, IMHO. The applications (process heat, electricity generation) are really secondary to that.

message: Wouldn't flywheels be a much more efficient storage mechanism?  They have around 90% transfer efficiency and I presume you could use the turbines to spin them up.  They'd be good at responding to variations in demand, have good lifetimes and would eliminate losses due to cooling. — Lee J Haywood (talk) 20:47, 22 February 2009 (UTC)

2. Solar desalination of sea water.  and

What about a design with dumb flat mirrors which have adjustable mounts (slides/bolts to hold in position) but no motors and a small number of robots which roll around adjusting them?  —Preceding unsigned comment added by 76.90.18.190 (talk) 06:08, 2 June 2009 (UTC)

message: I am thinking about adding an article about this company cleanergyindustries, they have taken over the manufacturing rights of the SOLO-stirling engine. I am a bit uncertain if it could fits in the Wikipedia-policy.
I have no connection to the company, the article would be a short presentation of the company with an update about their actual status, history behind the product, how it is related to the EUROdish and ENVIROdish projects etc. I plan to make an in-depth interview with their CEO. 
Would an article like that be appropriate on Wikipedia? Grateful for any comments.--Evteriksson (talk) 11:53, 7 April 2010 (UTC)
thread_title:  Add a company? 

message: Hi all, what do you think about this little gem of information? It applies specifically to Australia but it would be great to work it in somehow.
All of Australia’s dirty coal-fired power (29 gigawatts) could be replaced by solar thermal power at a cost of around $20 billion (AUS$). Meanwhile the current power-station operators are seeking to raise about $100 billion (AUS$) to replace them with dirty systems that will meet anticipated climate change and air pollution laws. The main political parties oppose or are lukewarm on solar thermal for ideological reasons.

replies: text: Great idea, except that your costs are at least 1 order of magnitude out - try hundreds of billions, not tens, and then there is the small problem of overcast conditions.

message: Hi. I have noticed the following types of solar power plants:
* Flat-panel
** Flat-panel photovoltaic
* Concentrated

** Concentrated thermal
But, is there a flat-panel thermal? Any examples? Rehman(+) 04:14, 9 August 2010 (UTC)

thread_title:  Solar Thermal Concentrator 

message: The quality of this article is poor.
"Higher temperatures leads to better conversion to electricity and the dish system is very efficient on this point."
The above statement contains a grammatical error followed by sub-literate expression.
"This prohibits any option of the direction of orientation of a given reflector."
Errors of grammar of compositional retardation of what's your first language.
"However, one fundamental difficulty with the LFR technology is the avoidance of shading of incoming solar radiation and blocking of reflected solar radiation by adjacent reflectors"
AMONGST the fundamental difficulties...
Here is where some capacity for composition and the English language could actually improve the writer's grasp of the material. Fundamental difficulty is a clumsy expression. It is better to think of inherent properties rather than fundamental difficulties. This naturally leads to a discussion of the various approaches for optimizing a design given those inherent properties. Words like "properties" and "characteristics" keep the focus on the subject material. Designs have properties. People have difficulties. The article is about design.  
The article is poorly written.184.45.6.155 (talk) 12:44, 19 June 2011 (UTC)
