== Photovoltaic systems ==

Nice work on Photovoltaic systems. All that info in the Overview section needs sources. If we can't come up with them, we should that content until we have it. Cheers. Jojalozzo 16:33, 31 August 2014 (UTC)

Thanks for noticing and the urgently need copy-edit. I'm planning to add citations tonight (CET), as I was just too exhausted last night from my edit;) If you have any suggestions to make, or some spare time to further copy-edit the article, I would really appreciate. Best, Rfassbind (talk) 17:19, 31 August 2014 (UTC)
Very nice work!! Jojalozzo 14:59, 1 September 2014 (UTC)

Growth of photovoltaics

Wow, I just wanted to say your edits over these last months have turned 'Growth of photovoltaics' into a really good article; I remember when it was much less extensive or referenced and I think named something else. Now it's all cohesively organized and very informative. Great work! TimeClock871 (talk) 00:32, 16 October 2014 (UTC)

Hello and muchas gracias for your appreciation! Let me know whenever I can do something for you :) -- Rfassbind (talk) 06:04, 16 October 2014 (UTC)

Dispute resolution

I have brought up the following dispute that you are in, with the resolution board. (talk) 00:19, 16 November 2014 (UTC)

As stated on the dispute resolution board, seen as this part of my reply to you was getting a bit long. I've taken to instead replying to it here.

As for your, so called - "...comprehensive [but not peer-reviewed] criticism of Weissbach's study I found here". I don't really need to say anything on this non-peer reviewed, German state funded, author's attempt to critique the Weissbach ET AL. study. As thankfully someone already has taken that piece to task! Read Cyril R's reply found in that link, they expose each and every one of the the authors "criticisms" as fraudulent bias. As this section was getting a little too long, I cut my retort to the above link, and instead posted it on User:Rfassbind's talk page, which you can read there.

For an example of the bias in the arguments from that state funded website: They try and counter Weissbach et. al's assumed 60 year lifespan for nuclear plants by arguing - hey the oldest continuously operating commercial reactor is only 45 this year? With guess this, "Solar PV panels are [now being sold by manufacturers with a lifespan tag of] 35 years..." - Did you catch that? They give readers a demonstrated ongoing lifespan value(45+) and then throw in a paper calculated value, by the solar PV industry, of just out of the lab solar panels! Tell me, are the solar PV panels installed 1-10 years ago in Germany, even half way to the D. Weißbach et al. papers generously assumed 25 year lifespan for solar PV? Nope! Rfassbind, maybe you can help here, What is the oldest, continuously operating, and commercial Solar PV panel? The German state funded piece naturally(because of bias) shies away from being fair and doing an equivalence by giving readers the answer to that important question, obviously! These are the kind of basic arithmetic failures and displays of bias that Cyril R takes them to task on. While I don't doubt improvements are being made to Solar PV, and that's great, and hey sure maybe cutting edge panels are being sold with a manufacturers lifespan tag of "35 years", but don't forget, so are Generation III reactors being sold with "80 years" tags. So Weissbach et. al are hardly biased to have chosen an assumed 60 years for the majority of presently operating nuclear plants, and a very generous 25 years for the majority of presently operating Solar PV panels - even though the vast majority of installed solar PV panels are not even half way there.

Anyways as both Cyril R(and everyone else knows) the assumed 60 year lifespan for nuclear and ~25 year lifespan for solar PV are design lifespan assumptions based upon assessments done by, and stated by their manufacturers. Unfortunately Cryril R didn't link them to the oldest reactor still operating, which is the F-1 (nuclear reactor), an infrequently operated research reactor turned on in 1946. I'll let you figure out how old that makes it. P.S it's older than Weissbach et al's conservative 60 year lifespan for nuclear power reactors, with 1940s reactor technology. To be fair, how many of the solar panels from the 1980s are still in commercial operation Rfassbind? Are there any?

If you can show us just 1 example of a solar panel with german levels of insolation from the 1980s that has been continuously operating for even 25+ years(bonus points if they're still commercial) and still pumping out ~70% of its initial nameplate/day one, rated energy supply, then I'll concede that Weissbach et al. are biased against Solar PV. Until then, good luck. (talk) 06:57, 19 November 2014 (UTC)

Above, an anon user disagrees with the 60-year figure for the life expectancy of nuclear reactors. The rant claims that solar PV power systems haven't yet proven their projected life expectancy of 30 years either. This comparison is inane. The operational lifetime for these two technologies depend on different things: while PV systems can run until they break down, nuclear power stations can't do that for well-known reasons. They are even being turned off way before they reach 60 years. In addition, here's a link to a PV-system from 1982. It's grid-connected, continuously-running for more than 30 years with an annual degradation of 0.5%. -- Rfassbind -talk 13:25, 28 July 2015 (UTC)

List of photovoltaic power stations

Sorting by date doesn't work for month+year, only just for year. If you try to make descending sort of that column, it will sort the rows that have a year in a normal fashion, but will not sort the rows with month in it, so it becomes just useless. –– Georgij Michaliutin (talk) 13:39, 14 January 2015 (UTC)

Hi Georgij, yes it does sort correctly. What browser do you use, my dear fellow editor? -- Rfassbind -talk 13:41, 14 January 2015 (UTC)
I use latest Safari on Mac. And I also checked the latest WebKit build, it doesn't sort there either. –– Georgij Michaliutin (talk) 14:19, 14 January 2015 (UTC)
Sorry my bad. Reading Help:Sorting#Date_sorting_problems now more carefully, it seems you're probably right, as the "isoDate" attribute I used does not work in all browsers (as I suspected after your post above). I see now your point, sorry for that misunderstanding. Let me see if there is a way to preserve the info about the month (e.g. transferring it to the comment column or something like that), OK? -- Rfassbind -talk 14:21, 14 January 2015 (UTC)
Ok :) –– Georgij Michaliutin (talk) 14:45, 14 January 2015 (UTC)
Very well. I'll post my suggestions to the talk page, soon. We can continue there. Thanks for your efforts. Cheers, -- Rfassbind -talk 14:57, 14 January 2015 (UTC)


I really liked your work on Comet. The image looks awesome now. Can you do that magic again on Dwarf Planet? Tetra quark (don't be shy) 16:38, 18 January 2015 (UTC)

Oi tetra, tudo joia rapaz? Sure, I can group them into a single "image-collage". I've done that before here and here.
  • Dwarf Planet: since there are "only" five lead images and all of them are more or less square-shaped, there are two possibilities: either we find one more image to have a group of six symmetrically aligned images, or, one of the 5 existing images will be much larger than the others (e.g Pluto, that soon will be replaced). What you think? Also, there is already an image that compiles some dwarf planets (image here, although it does not include non-TNO Ceres).
  • Talking about comets, maybe you noticed that there are two (sub)-articles, namely Comet tail and Antitail. I think Antitail should be merged into Comet tail. What do you think?
Thanks for your feedback. It's the first one ever I received for the many image-compilations I've done so far. Cheers, -- Rfassbind -talk 21:02, 18 January 2015 (UTC)

──────────────────────────────────────────────────────────────────────────────────────────────────── I just added a 5-image-compilation on Dwarf Planet.

Oh, um BR! Que coincidência. Bom, ficou ótimo a compilação de images. Você poderia aumentar o tamanho delas um pouco? Tanto no Comet quanto no Dwarf Planet. Tetra quark (don't be shy) 17:10, 20 January 2015 (UTC)


You recently added BrownDwarfComparison-pia12462 to the Brown Dwarf page. I think the image is incorrect (even though it's from NASA). The Sun should be about 10 times the diameter of Jupiter, but the image shows it only as about 5 times bigger. See Sol_Cha-110913-773444_Jupiter, further down on the page, for a better comparison. Tbayboy (talk) 14:33, 31 January 2015 (UTC)

@Tbayboy: Wow, yes, you're right. Good catch Tetra quark (talk) 15:16, 31 January 2015 (UTC)
Hi Tbayboy (and User:Tetra quark), you're very carefully, indeed! What do you suggest to do? Do you think the image in the lead of the article Brown dwarf isn't good enough to give a rough idea to the general reader? Pls let me know, thx. Cheers, -- Rfassbind -talk 15:18, 31 January 2015 (UTC)
As you can see, I've added a clarification in the caption of that image. I guess that should be enough. Tetra quark (talk) 15:20, 31 January 2015 (UTC)
Seems fair to me, thx! -- Rfassbind -talk 15:25, 31 January 2015 (UTC)
Okay for now -- with Tetra's change, the Brown Dwarf editors can see what the issue is. I've added the issue to the file's talk page and ping'd Kheider (the original uploader) (what I should have done in the first place, rather than doing it here), since other uses of it might want to do something as well. Tbayboy (talk) 17:00, 31 January 2015 (UTC)

────────────────────────────────────────────────────────────────────────────────────────────────────Thx, let me know if there's something I can do -- Rfassbind -talk 17:04, 31 January 2015 (UTC)

Editing main table on List of possible dwarf planets

You have been making global edits to the main table on List of possible dwarf planets. I agree with the substance of the edits, but there is an issue: that table is automatically generated from a program. This allows me to do easy updates from the sources (the Minor Planet Center TNO lists and Brown's Dwarf Planets list) without having to carefully look through the sources searching for changes. When you make a change to the table, I have to update the program generate matching text so that the next update doesn't clobber your changes. (I do an update about every month, so that the numbers in the table that come from those source, and the order of the entries, don't have to be managed by hand, and so stay true to the sources.)

See the discussion about it on the talk page.

The reason for telling you this is so that you don't waste too much time editing the table when a change to the program (followed by an update from the program) only takes me a few minutes. If you're just doing a global search+replace editor function then it's okay (doesn't take you any longer to do that than it does to explain the change it to me), but if you have to individually edit a lot of lines then it's better to do it through with the program. The following columns are NOT generated automatically from the sources, so you can changes the numbers/texts there with no issue: Measured Mass, Measured Diameter, Tancredi, and Category.

The program I'm using is a Microsoft SQL Server Express script (SQL source code). I can give you the source code if you like, but you need to have and know (a little) MS SQL Server Express (freely downloadable) to do anything with it. If you have a good working knowledge of any other SQL system, you can probably port it there, too, since it's a simple program (it doesn't do anything tricky).

Furthermore, please tell me if you know a place to keep this code on Wikipedia. I tried putting it on the talk page, but the code contains wiki-markup, so it blows up the page. I just did a quick, simple test. There must be a way to do it, but I'm not that fluent in wiki-editing.

Thanks, Tbayboy (talk) 17:56, 31 January 2015 (UTC)

Hi,Tbayboy. Ooops, I thought there was something "strange" with the wikitable's syntax when I did my edit. That's why I let the spaces and newlines between the pipes-characters untouched. Of course, I'm sorry to have troubled your established procedure of updating the data and I very much appreciate your approach in letting me know instead of just reverting the whole shebang with a grumpy edit-note.
Well I'm rather the MySQL-type of web developer and with no knowledge of Microsoft but I'm curious to take a look at the code and fiddle with it if you allow me too (by the way the "possible dwarf planets" wiki-table is an excellent one). In any case if you plan to make an update any time soon, it's AOK just to paste over my changes. My intention it to improve articles and not to complicate established procedures, so when I'm misjudging the situation, it's only fair to undo my changes.
As for posting the code: there are three tags and templates I can think of that would be helpful in posting code, I guess:
  • the <pre> tag helps to display the code line by line (without any wrapping of new-line characters)
  • the template {{hidden begin}} and {{hidden end}} allow you to collapse text-content (hide/show) in a "spoiler-box"→see Template:Hidden begin
  • the <nowiki> tag prevents wikipedia to parse the wikicode and displays the way it is on the website.
I guess all these together should resolve pretty much every problem. Why don't you create a user page? Add a short "Hello" and try to post your code there? I definitely would appreciate.
I still have to read the discussion you mentioned above. I'll do so ASAP. Let me know what you think and again, sorry I so ignorantly intruded your established procedure. -- Rfassbind -talk 19:18, 31 January 2015 (UTC)
No apologies necessary! This is not an established process, it's fairly new and still at the trial stage. I was expecting such a thing to happen. You can appreciate the problem of keeping all those numbers up to date and in order. You made other changes a little while ago — which I've incorporated in the program — but I didn't say anything then because I didn't recognise your handle as being a regular editor on that page, so I figured there was a good chance you might not be doing much more.
Thank you for the wiki-fu above. I'll try it later (I'm at work at the moment). I very much would like to have somebody else able to do the update, since it's not good for the page to rely on one person. I can switch over to MySQL if you can can port it there — another thing I was expecting might happen. I don't think there's that much difference between them, but I've never worked with MySQL. Tbayboy (talk) 21:05, 31 January 2015 (UTC)
I've incorporated your changes (except the Ceres thing, which is a little harder; I'll work on it later). I was able to get the code on a page and display nicely, thanks to you. You can see the current code and the resulting table in my sandbox. When I do the next update (probably next weekend), I will put the code on the List-DP talk page, replacing the current collapse text at the top which contains an old copy of the previous version of this table. Tbayboy (talk) 00:35, 1 February 2015 (UTC)
Well done! Thx for your efforts and I will definitely study the code in detail. CU, -- Rfassbind -talk 00:43, 1 February 2015 (UTC)



Thanks for your outside help mediating at dark matter. Wording disagreements are tough, since sources don't really have anything to contribute one way or the other, and it's certainly much ado about one word. —Alex (ASHill | talk | contribs) 02:11, 8 February 2015 (UTC)

Tonne of coal equivalent

I think you have a "million" missing in your edit:

As per the World Coal Association: 1 million tonnes of coal equivalent (Mtce) corresponds to 0.697 tonne of oil equivalent (Mtoe)[24] As per the International Energy Agency 1 million tonnes of coal equivalent (Mtce) corresponds to 0.700 tonne of oil equivalent (Mtoe)[25]

? should be

As per the World Coal Association: 1 million tonnes of coal equivalent (Mtce) corresponds to 0.697 million tonnes of oil equivalent (Mtoe)[24] As per the International Energy Agency 1 million tonnes of coal equivalent (Mtce) corresponds to 0.700 million tonnes of oil equivalent (Mtoe)[25]

Or have I got this all wrong? ThoughtIdRetired (talk) 11:37, 5 May 2015 (UTC)

@ThoughtIdRetired: That's correct, thank you Sir! This is what happens when an (unfinished) edit leads to another article, that needs to be edited first, which in turn requires another article to be edited, linked or redirected first. Best is not to write million at all. I amended tonne of coal equivalent accordingly. -- Cheers, Rfassbind -talk 11:52, 5 May 2015 (UTC)

Energy in TW?

This figure is inspired by a given source. The source indicates that the "Worlds power consumption is 16 TWy/y". This is equivelant to me stating that for my house the energy consuption is 20000 kWh/y. On your figure this has changed to "Worlds power consuption is 16 TW". Now, kW, TW etc is normally used to express power/leistung. To me it would be very unfamiliar to say that the power consumption of my house is 1950 W.

Can you explain to me why the unit is changed from TWy/y (energy per year) to TW (power/leistung)?

(Please answer on this page) Regards KjellG (talk) 12:26, 30 May 2015 (UTC)

Thank you. I see the problem: the label talks about energy (world energy consumption) which is represented by the sphere, while the figure right next to it displays the world's power demand (16 TW). I uploaded a revised version, that now reads "power demand of 16 TW". Hopefully, this amendment helps to clarify the diagram.
As you know, energy per unit time is the same as power. The units TW-yr per year (as in the original) is equivalent to the unit TW (terawatt) and both mean power, not energy (i.e. year is cancelled out). I thought adding the labels "annually" and "total reserves" on the bottom of the diagram would be a much better solution than using the non-SI-compliant version of TW-yr/year. Please let me know what you think. Cheers, -- Rfassbind -talk 14:27, 30 May 2015 (UTC)
I will come back with more thoughts, but will take some time. Meanwhile, this article World energy consumption seems to use TWh per year or TWh/y. The differece between TWy/y and TWh/y is only a scaling factor. I agree that TWy/y is less familiar than TWh/y, but the numbers has less digits and looks better on the figure. I can not see TW used anywhere in the World energy consumption article? I see your point that y/y can be regarded as "1" and left out, but there are numerous papers that uses energy per day, per week, per month per year: kWh/d, kWh/w ... kWh/y. TWh/y or TWy/y is only an extension of this. Energy is the time intergal of power. By adding per bla, bla, one clearifies over what time interval the power is intergated. By graphing kW for a household, one would see a graph looking like white noise. By graphing kWh/h, or kWh/month, one would more clearly se how the power fluctuate through the day (month or year). This can be seen here, unfortunately in Norwegian. From my point of view the original paper is the best way of expressing this matter, but with a "comment" regarding TWh vs TWy. I will make a suggestion for a new figure, hopefully tomorrow eve.
For the renewable sources, are the values given for what has been build until now or what can be built in total? KjellG (talk) 22:57, 30 May 2015 (UTC)
Sure, any time. Maybe it would be helpful in the process, if you asked yourself why the author of the original diagram chose to use "terawatt-year per year", instead of the much more conventional "terawatt-hours per year". The answer is crucial for grasping the concept of the drawing. Also, I recommend to double-check with the diagram's extensive description. Cheers, -- Rfassbind -talk 00:01, 31 May 2015 (UTC)

This template must be substituted. Replace {{Autopatrollergiven with {{subst:Autopatrollergiven.

Wikipedia Autopatrolled.svg

Hi Rfassbind, I just wanted to let you know that I have added the "autopatrolled" permission to your account, as you have created numerous, valid articles. This feature will have no effect on your editing, and is simply intended to reduce the workload on new page patrollers. For more information on the patroller right, see Wikipedia:Autopatrolled. Feel free to leave me a message if you have any questions. Happy editing! Sadads (talk) 17:34, 1 November 2015 (UTC)

Wikipedia Rollbacker.svg

Hi Rfassbind. After reviewing your request for "rollbacker", I have enabled rollback on your account. Keep in mind these things when going to use rollback:

  • Getting rollback is no more momentous than installing Twinkle.
  • Rollback should be used to revert clear cases of vandalism only, and not good faith edits.
  • Rollback should never be used to edit war.
  • If abused, rollback rights can be revoked.
  • Use common sense.
If you no longer want rollback, contact me and I'll remove it. Also, for some more information on how to use rollback, see Wikipedia:New admin school/Rollback (even though you're not an admin). I'm sure you'll do great with rollback, but feel free to leave me a message on my talk page if you run into troubles or have any questions about appropriate/inappropriate use of rollback. Thank you for helping to reduce vandalism. Happy editing! Sadads (talk) 17:34, 1 November 2015 (UTC)
