Talk:Compact linear Fresnel reflector

Merging this into "Fresnel reflector"
I will probably merge this into a new article on Fresnel reflectors if no one has objections. Lumenos (talk) 20:56, 13 August 2009 (UTC)

Questions and Comments on Content
There are a couple of points in this article which I find confusing.

First of all, what is a "thermal fluid"? I am familiar with the concepts of heat exchangers but I don't recognize this term and there doesn't seem to be an article on it.

Secondly, I don't understand the statement in the Design|Reflectors section about "perpendicular incidence." What does this refer to? An Angle of Incidence of 90 degrees doesn't seem to make sense, because this would put the rays parallel to the mirrors' surfaces (unless I'm mistaken?). Putting the mirrors perpendicular to the rays also seems counter-intuitive and contradicts the pictures on this page.

Finally, the advantages of using Fresnel reflectors are very vague. Even with an understanding of apertures and focal lengths, I don't see what advantages this implies when compared with more conventional systems. NiteSite (talk) 19:52, 7 April 2010 (UTC)


 * Also, in the Design|Absorbers section, I'm not sure I understand intuitively how a close proximity of the panels reduce the length of the absorber lines. Does this simply mean that you need less length to collect the same amount of energy since more mirrors are focused on it?  —Preceding unsigned comment added by NiteSite (talk • contribs) 20:09, 7 April 2010 (UTC)

The line:  "... enough solar collectors to provide 200 MW of power per month." does not make sense. Was the "per month" a copy-paste accident? — Preceding unsigned comment added by 98.171.190.17 (talk) 04:34, 22 October 2013 (UTC)

Response to Questions and Comments
Dear Nitesite,

Thank you for your interest in improving this article. To answer your questions, when I used the term "thermal fluid" I was refering to a hot oil that carries large amounts of heat energy throughout the system. It's primary function is as a vessel. I have since realized that a better term would be "heat transfer fluid", so I have changed the article to reflect this.

I have also changed the word "perpendicular" to "appropriate" to render the phrase "appropriate angle of incidence" if you have any other suggestions you feel would benefit the article more than this word choice, feel free to make any edits you see fit.

With the state of technology today, there is little advantage to using Fresnel reflectors in solar collection, especially with the advent of thin film parabolic reflectors, a cheaper, more effective alternative. A few years ago, it was difficult and expensive to make parabolic reflectors using sagged glass. It was in response to this technology that Fresnel reflectors found their niche in innovation and were heralded for their performance.

Finally, you were correct in your assessment of how proximity enhances performance. When multiple reflectors are focused on the same pipe, one no longer requires longer pipe to achieve the same heat transfer capabilities.

Thanks again for your help! —Preceding unsigned comment added by Jrkenneyjr (talk • contribs) 03:44, 7 May 2010 (UTC)

Title and text not manual of style conformant
Compact linear Fresnel reflector and linear Fresnel reflector are not proper nouns so linear and reflector should not be capitalized in the title and only Fresnel should be capitalized the text. The acronyms should remain all caps. Unless there is disagreement I will fix this. Joja lozzo  01:29, 16 May 2011 (UTC)
