Rational Section

I'm the president of a company that builds solar refrigerators. I think the rational discussion is not accurate. I've never edited a Wikipedia. It is permitted/normal to deleted sentences? DavidBergeron3 (talk) 06:43, 27 September 2013 (UTC)

Yes, it is normal to do it, just remember to add some sentences about it in "edit summary"

Rationale Section

While adding citations, it was noticed that the Rationale Section was lifted directly from: http://www.scientificamerican.com/article/solar-refrigeration/

This comes in direct violation of the copyright rules of wikipedia. However, I suggest not to delete it for copyright violation but to rewrite it and paraphrase it.

The direct copied section is actually 2.5 years old. No one has made any attempt to fix it, so for the integrity of the article, the whole thing should be removed.

https://en.wikipedia.org/w/index.php?title=Solar-powered_refrigerator&diff=504583380&oldid=479944617

If someone still wants to work on doing paraphrasing, well, there's the source article and the edit history to refer back to.

Non-evaporative loss heat-using coolers?

Pot-in-pot deals with using an evaporative cooling system that loses coolant in evaporation, to cool. Whereas a standard refrigerator, the evaporant is enclosed in a closed system, and recondensed to be evaporated again. There are systems that instead of using electricity to energize this system, use heat instead, absorption refrigerators (such as Einstein fridges). This article should also cover using solar heating in a non-evaporative process. (such as heat output from a solar heater, or a solar concentrator) -- 67.70.35.44 (talk) 22:16, 19 October 2014 (UTC)

If this article should only cover photoelectric refrigerators, then it should be renamed to solar-electric refrigerator instead of the current name -- 67.70.35.44 (talk) 22:18, 19 October 2014 (UTC)

Too much irrelavent or misleading information

The discussion of refrigerants/foaming agents belongs in a separate article. Solar refrigerators and non-solar refrigerators use the same refrigerants and blowing agents so solar refrigerators do nothing to address that issue and the article seems to imply that they do. The entire paragraph on "Rational" needs to be rewritten. DavidTucson (talk) 00:28, 5 August 2017 (UTC)

Edit request

In the Technology section, add a new paragraph with the statement "In 2019, American company GoSun introduced a solar-powered portable refrigerator utilizing a brushless compressor, a lithium battery and solar panels, which allow food and drinks to be kept cold without ice, while also being able to charge the user's devices" (refs provided in the collapsible section below). This is to illustrate a new concept developed for solar-powered refrigerators (charging devices while refrigerating).

Extended content

Technology Solar powered refrigerators are characterized by thick insulation and the use of a DC (not AC) compressor. Traditionally solar-powered refrigerators and vaccine coolers use a combination of solar panels and lead batteries to store energy for cloudy days and at night in the absence of sunlight to keep their contents cool. These fridges are expensive and require heavy lead-acid batteries which tend to deteriorate, especially in hot climates, or are misused for other purposes. In addition, the batteries require maintenance, must be replaced approximately every three years, and must be disposed of as hazardous wastes possibly resulting in lead pollution. These problems and the resulting higher costs have been an obstacle for the use of solar powered refrigerators in developing areas. In the mid-1990s NASA JSC began work on a solar powered refrigerator that used phase change material rather than battery to store thermal energy rather than chemical energy. The resulting technology has been commercialized and is being used for storing food products and vaccines. Solar direct-drive refrigerators don't require batteries, instead using thermal energy to solar power. These refrigerators are increasingly being used to store vaccines in remote areas. In 2019, American company GoSun introduced a solar-powered portable refrigerator utilizing a brushless compressor, a lithium battery and solar panels, which allow food and drinks to be kept cold without ice while also being able to charge the user's devices.

​Not done, not shown to be notable enough to warrant a mention here. Reads like a promotional namedrop. – Thjarkur (talk) 15:40, 6 September 2020 (UTC)

@Þjarkur: Two questions: First, I didn't realise there were notability guidelines for statements in articles; no buzzwords have been used and I would argue that the requested edit wouldn't match the sort of edits advised against at WP:SOAP. What particular guidelines have been contravened to warrant the declination of my request?

Second, if my earlier request cannot indeed be fulfilled (I'd still want to hear your answer to my first question), would it be better to include the statement as follows? "In 2019, solar-powered portable refrigerators utilizing a brushless compressor, a lithium battery and solar panels were introduced. These allow food and drinks to be kept cold without ice, while also being able to charge the user's devices." (Refs provided in the collapsible section below).

There are a thousand gadgets that are manufactured every year that are amalgamations of already existing technology. Mentioning specific ones sourced to non-independent submarine articles is not WP:DUE and this particular mention In 2019, American company GoSun introduced... would only be there for promotional purposes. For this edit request,  Not done it has not been shown that this is worthy of note, sources don't show that "utilizing a brushless compressor etc." is actually novel. And yes a lot of verifiable information is kept out because it is not relevant enough to mention in a general encyclopedic article. – Thjarkur (talk) 21:34, 7 September 2020 (UTC)
