Open-source syringe pump[edit source]

Dear Dr.Pearce,

I am trying to recreate the Nema 17 syringe pump that you did in your Open-Source Syringe Pump article. Could you tell me the holding torque of the Nema 17 motor you used please.

Thank you, Breathnach -- Depends on the motor. The motors we use have a holding torque of 5.5kg-cm. --Joshua (talk) 10:54, 11 December 2014 (PST)

GreenAT project[edit source]

Hi, Prof. Pearce. This is Jianlang Mai from MECH 425. I have finished my GreenAT project and wonder if you can take a look at my page and give me a little bit of what you think i should add on the page, or any comments. My page is https://www.appropedia.org/Solar_water_disinfection_system_with_solar_heating#Solar_Water_Disinfection_System_Construction . Thank you very much.

Industrial symbiosis and industrial ecology[edit source]

Hi Joshua,

I just saw your edits - great to see your valuable contributions here!

I was just chatting with Wikipedian and Urbepedian ChaeraniW about her master's paper... Industrial symbiosis and industrial ecology definitely need to be on Appropedia, as does natural capitalism - I'd suggest we start with a single page, and split later if appropriate. --Chriswaterguy · talk 05:32, 25 April 2007 (PDT)

Okay, I lumped the first two together, but made natural capitalism separate. They're just stubs - I figure it's always better to have a stub than nothing, as long as there's at least a good link.

What would be great is if someone allowed us to use some good quality information on these topics - i.e. released their material under GFDL. Do you have any suggestions? INDUSTRIAL SYMBIOSIS, Literature and Taxonomy by Chertow (2000) looks useful. --Chriswaterguy · talk 06:37, 25 April 2007 (PDT)

Maybe you'd wanna email Marian Chertow directly and ask whether she would be interested in writing short article for Appro.. Chaerani 01:12, 26 April 2007 (PDT)

Hi Dr. Pearce,

Thank you for that article. It was definitly interesting- in fact back home at my college I have to submit a senior year project when I return from Clarion University in order to be given my degree. Over the past few days I was thinking of what to do it on- this seems perfect. I look forward to meeting with you in person on thursday.

Ecological sanitation[edit source]

Hi Joshua,

Is ecological sanitation an example of industrial ecology? I know it's not industrial, but otherwise it seems like a perfect fit. --Chriswaterguy · talk 05:20, 18 October 2007 (PDT)

AAEA[edit source]

Hi Joshua,

"Great catch and a spectacular learning opportunity for my students. It is really interesting that the main African American Enviro group tends to be against the majority of mainstream groups. All kinds of good material. E.g. That nuclear energy is "emission free" -- I have a paper coming out on the topic and embodied energy in 2008. "

Even more interesting in my mind that they are so strongly pro-Bush - but then, they adopt so many Republican/environment-skeptic positions that I shouldn't be surprised. Anyway, I welcome an alternative voice - they as well as the mainstream voices all need to be examined.
btw, don't forget to sign! And if you have time, have a look at Appropedia submission for BFI prize - we want to get the basics done within a day, then set the wordsmiths to making it hang together nicely. I'm going to add something about service learning - feel free to expand that or correct other glaring omissions. --Chriswaterguy · talk 09:28, 28 October 2007 (PDT)

Natural Sequence Farming[edit source]

"Hi Chris

Actually I had already caught the student purging the page and warned him -- if it is not corrected by 5pm Friday I will go back and fix everything. Sorry for the trouble -

--Joshua 05:50, 6 December 2007 (PST)"

No problem - it's part of the learning process!

I'm wondering about the practice of putting the class notices on pre-existing pages though - note we don't have a policy or guideline on this, but we should think about it. Another editor may already be editing that page. Or even if they're not, someone being asked to refrain from editing a page that they started may not create good feelings. Perhaps a branch of the article should be created, to be merged once the class is finished?

Anyway, good to see your students active on the site! --Chriswaterguy · talk 22:22, 6 December 2007 (PST)

Article count and Spanish translation[edit source]

Hi Joshua,

Thank you for pointing out the article count issue. It broke during our most recent update, I just tried to fix it and I made it worse. At a loss of how to fix it, I have changed the main page to cite all of our pages, which in some ways is more accurate since we have a lot of content outside of the Article Namespace. I also added edit and file counts. We are currently redesigning the front page, so hopefully this will either be moot or fixed.

I am very excited about Spanish translation. I think that this could provide a great mutual benefit to service learning language courses - giving students something real to work on, providing more sustainability material in Spanish and providing teachers a mechanism to check work. We are ready to roll on that, and I would love to discuss it more. I am planning on approaching a couple of courses this semester as well. Let's coordinate. Via email?

Thank you, --Lonny 18:33, 1 January 2008 (PST)

Thanks Dr. Pearce! I'll start doing that.--Fatima 18:53, 12 February 2008 (PST)

Hello Dr.Pearce, I created a page Polymer recycling and another one how is plastic recycled. I tried to make the page how is plastic recycled under polymer recycling. When I open the page it says it is under that category but when I open the Polymer recycling page there it doesn't show that there is anything under it. Could you tell me how to fix it please? Thanks--Doaa 11:50, 11 April 2008 (PDT)

How can I make Polymer recycling a category? Can it be a category under the category green chemistry? I also want to know how to form a subcategory?

Thanks--Doaa 12:09, 11 April 2008 (PDT)

Porting[edit source]

Dr. Pearce,
Some of the articles on the Practical Action website are already on appropedia in the ITDGbot page category. Should I still port those articles from the website to appropedia?--Fatima 17:45, 15 April 2008 (PDT)

Thanks Dr.Pearce. I'm not sure what you mean by 'search for the name of your article or keyword in appropedia -- and then link anywhere it pops up back to your article'...--Fatima 12:34, 16 April 2008 (PDT)

Changes to Appropedia[edit source]

Dr. Pearce, the following are some changes i would suggest to appropedia. I will compile a more extensive list later but i've got exams to worry about so this is just a quick list:

- I would use your template as the default template. It is much cleaner then the original. Although i would not use your editor as the defauls as it is too unfinished
- I would not use any transparent background gifs. They do not appear correctly on all monitors (sometimes having solid white backgrounds). They are very low quality especially for a logo.
- If they chose not to go to your template, at least go to another. Textured backgrounds like the bricks are just not up to date anymore and don't look professional.
- After an image is uploaded there should be the option to go back to the page you were on. It gives you the option to close the window but I just want to go back to wherever i was.
- You should be warned before you navigate away from a page you are currently editing- it's hard to know which links will navigate away from what you are editing which can result in lost information.
- You should be able to automatically go to the classic view (this should be an option within preferences).
- while uploading it should automatically add the original extension if none is given. I doubt the code is there to do conversion between file types during upload so why would you even give the option to change the file extension?
- I am not sure i understand the logo and that it is catchy and representative of appropedia and all it stands for (though that could be me just not knowing the story behind it)

That's all for now. All that being said i think it's an amazing idea and is leaps ahead then some of the other wiki's out there. Hope some of this helps and isn't taken in the wrong light.

copyvio[edit source]

Did you want the whole of Use of Silicon Anodes in Lithium Ion Batteries deleted? I wasn't sure, as the notice was in one of the sections, and there has been some editing since you placed the notice.

Also re Hot-Melt Extrusion - are the images also copyvios? What I'm wondering is: if an editor just deleted the copyvio text, and an admin removed the copyvio images... would there be a stub article left behind? (Maybe not a good one, but something to prompt a reader to build on it.) In such cases, the class attribution could be removed, if it's not the sort of article that the class would want to claim credit for.

Thanks for all your work! --Chriswaterguy 23:49, 13 January 2010 (UTC)Reply[reply]

Data Center vs. Server[edit source]

Clarifying open vs "open access"[edit source]

Hi Joshua,

I don't know if anyone has seen my comments at Talk:AT Sourcebook and Talk:What is AIDS?.

Great to see so much activity from your students. Is there anything we can do to help the students with categorization, or should we just leave it till someone adds categories eventually? I don't know if they would find Appropedia:CategoryTree (more user-friendly) useful; or perhaps Appropedia:Fundamental category tree (more thorough). --Chriswaterguy 10:21, 11 February 2010 (UTC)Reply[reply]

AT CAD team[edit source]

Hi Joshua, thanks for supporting the AT CAD team project/idea. For the moment, I'm working on a SketchUp manual so I won't be doing much modelling for now. When this is done, I'll probably focus mostly on CAD designs of others (ie velomobile, ...). Note that we can place snapshots at relevant articles at wikipedia, this also increases the popularity of Appropedia. We still have some issues to work out, ie how we'll share the models: I was thinking about a file hosting service (see village pump) and/or Google Warehouse. KVDP 09:17, 23 February 2010 (UTC)Reply[reply]

Hi Joshua,

I just finished the SketchUp Beginner Manual. You can now use it in your lessons. KVDP 12:06, 8 March 2010 (UTC)Reply[reply]

Hey Joshua,

I was wondering whether you already noticed the http://costeffectiveaid.blogspot.com/ website I made to accompany the AT CAD Team ? Aldough the website is pretty unused by me for now, it sets a endpoint to work to (urban CAD-modelling rather than CAD-modelling of single objects). In addition, it may also help Appropedia for practical projects (eg improvements of AT villages, factories/AT workshops, ...). I've sent you an invite to become an co-webmaster. You can then use the tool once we progressed far enough (once we've done our current designs), and/or invite a student yourself to become co-author and update the site. KVDP 08:15, 10 May 2010 (UTC)Reply[reply]

Hey Joshua,

checking student contributions[edit source]

I just came across this student work from 2007 - probably a rare example of plagiarism that didn't get picked up at the time. Probably too late to be of use to you, but just letting you know.

Effect of snow on PV's[edit source]

Hello Joshua. This is User:kili. I have been reading your pages. Although you are currently researching to establish the exact figures caused by snow losses..I thought of this... I think a bit of low tech may solve the problem-by incorporating wipers that will be wiping snow whenever it falls on the PV’s panels. This process can either be made automatic or manual. If this sounds great I am willing to work on it more.

Real number on gains[edit source]

Hello Joshua. Well automated systems may work by creating clever circuits that may sense snowing-for example light-low voltage, increased weight e.t.c. But still all this should, may be wait for real number in gains so as to see if the costs of those systems are justified. And employing people from the north(?, never been out of here, is that a place, locality or something else?) may also be appropriate with all the unemployment! But will paying them be viable? Isn't there a chemical material that may speed up the melting of snow? user:kili

Nuclear power page and MOST report[edit source]

Hi Joshua, I just saw MOST prepared a report regarding nuclear power as a appropriate energy source. I just wanted to let you know I added some info at Nuclear_power and Limitations of nuclear power as a sustainable energy source. In specific, look at the POST report, which has a comparison (full lifecycle) between the power plants. I think that the cannibalistic effect you mention is probably bigger with other power plants (ie wind turbines, ...) than what it is with nuclear power plants (atleast if you take into account the amount of power production, ie effect per GWh) Perhaps it's also a good idea to take a look at the different types of power plants, ie the inherently safe designs I mentioned a while back, generation 4 reactors (fast breeders) and smaller reactors (micro nuclear reactors, ...) Also take a look at MYRRHA, I believe that used fuel at the current power plants can be reprocessed and used again, resulting in a used fuel that is then only 100 years radioactive, as compared to thousand(s) of years. Also, there's no mentioning of the specific fuels (I believe reactors use not only uranium but also plutonium, some use a mix thereof, some use low enriched, others high enriched nuclear fuel, ...)

Service learning portal suggestions[edit source]

OLPC for Mobile RepRap[edit source]

Hello Dr. Pearce,

I noticed you added One Laptop Per Child as a possilbe solution for the current project. I was wondering if you've had any success in getting the project approved by the OLPC committee? When I first joined this project, I thought OLPC would be a great organization to team up with, but unfortunately we submitted a project proposal and got no reply. The last I checked the XO's were not for sale, only for use in conjunction with approved projects. I think it would be great if you, or the team at Queens have had success in creating a partnership. --Debbie King

Kit price[edit source]

I got your note on my talk page - I'm not sure about the netiquette here so I'll just respond here…

Kit prices in the US are even lower than in Ontario. That's due to the non-existence of the "made in Ontario" clause, which adds about 25 cents overall. I suspect you can get a complete system kit using string inverters for about $1.75, and add maybe 25 cents for micros. We have distribution out of the southern US, so if you want to know what the real going rate is, feel free to write back and I'll look up current pricing.

Installs in the US (and everywhere else) are generally less expensive than here in Ontario. Here we have to put in a second electrical meter, and that causes all sorts of extra work for the electrician. So I'm just guessing, but I suspect that you should be able to install and commission a small system, say around 5 kW, for around $3.50 to $4 depending on how much of a DIY you are. At that rate you're looking at an LCoE of 20 to 25 cents.

It's pretty amazing when you think about it. And this is the main reason I think we need to stop working on fusion as an energy source.

Domestic power system[edit source]

Hi Joshua, I was wondering whether you know of any 3-phase power 230 V, 50 Hz power plugs and sockets. I know that in industrial power plugs and sockets, 3-phase power is used, yet I assume that regular power plugs/sockets is 2-phase (see http://en.wikipedia.org/wiki/AC_power_plugs_and_sockets#CEE_7.2F7_plug) ? In industrial power plugs/sockets, I'm not sure whether 230V/50Hz can be provided (most have other voltages/amps). I would like to know the name of the described plugs/sockets, if they exist.

The idea is that an extra power conversion can be avoided, and that the domestic appliances can be used to operate on 3-phase power, which is more efficient than 2-phase power. The idea is to make a design of a domestic kit-type system which could be (theoretically) supplied to people without a domestic electric system (in in the developing world). I had this idea for a while (see http://en.wikiversity.org/wiki/DIY_home_electricity_system ) yet with the idea on using 3-phase power, I seem to have progressed a bit further. Perhaps that once I figured everything out, I'll make a 3D model, ie together with other domestic equipment (see https://www.appropedia.org/Open_design_water_heater ) KVDP 04:42, 13 November 2012 (PST)

Openoffice and libreoffice[edit source]

Is it worth mentioning in the text of your graph page that openoffice has now been replaced in most linux distros with libreoffice? It is a fork, but I think most of the programmers went from OO to libreoffice. Anyway, if you're using linux, you're much more likelt to see libreoffice than OO. I've not used the graphical parts, but I'm guessing it is much the same as it was in OO. Joeturner 10:38, 15 January 2013 (PST)

Solar sludge treatment[edit source]

Sorry to post again, I'm thinking about the science behind sanitation interventions, and I was wondering if it was worth putting this solar concentrator as a page for appropedia. Is it scalable? Is it technically any different to a solar oven? Joeturner 11:45, 15 January 2013 (PST)

Thanks for the reply, I can start an appropedia page, but I'm not sure where it would best fit. With the solar pages or somewhere else? Joeturner 00:06, 16 January 2013 (PST)

And another thing I have been wondering: is it possible to build a solar UV concentrator? Or perhaps a UV source which is solar powered? I know your students have had projects where they use ambient UV from the sun, I am wondering if it is possible to scale up and strengthen the UV. I am not an engineer, maybe it is not possible.

I noticed the first design issue with the original layout template.

  • "Do not use = wikimarkup to create section headers within a template which is intended for use in article space – this will create an [edit] link that when transcluded will confusingly open the template for editing."

How it plays out here is that section headers show no edit link, like at AT Sourcebook/Forestry/Practical Guide to Dryland Farming: Planting Tree Crops. I'm going to take out the "text" parameter, so that what's left essentially becomes a header template. I'll also change the istructions accordingly. --RichardF 07:30, 28 April 2013 (PDT)

The main Talk page (Level 1) usage instructions (Talk:AT Sourcebook/Usage) and layout page - AT Sourcebook/Layout are live. I'll update various pieces as time goes by. --RichardF 07:32, 29 April 2013 (PDT)

Hello Dove, Just like when you were Auntof6, please do not argue with Joshua about the pages that he is maintaining. I am glad you have found a way to be more helpful here. If you have any questions, please ask on my userpage and not here on Johsua's.--Lonny (talk) 18:28, 26 November 2018 (PST)

MOST templates[edit source]

Thanks for contacting me! I understand what you mean, but I'm redesigning the main page so that it can extract galleries directly from the pages, without the need of sub-pages! Check out the new main page at Welcome, and in particular see Welcome/Gallery and the Template:Excerpt. Kind regards, Sophivorus (talk) 13:42, 30 September 2020 (UTC)Reply[reply]

To reuse any content from any page in any other page, check out the new Template:Excerpt. I just updated it's documentation. For example, to transclude a section containing a gallery, the wikitext would be:

{{Excerpt|Category:Engr308 Technology and the Environment|Analysis projects}}

which will output:

Octicons puzzle-piece.svg

Will this do? Sophivorus (talk) 13:55, 30 September 2020 (UTC)Reply[reply]

Thank you! If you restore the changes I made to the MOST category, your code should work. :-) Sophivorus (talk) 14:07, 30 September 2020 (UTC)Reply[reply]

Status[edit source]

Hi Joshua, hope you're well! As part of our effort to reduce and simplify Appropedia templates, I've been working with Emilio on a strategy to integrate your Template:Status into the new databoxes. Can I ask you to check out this diff and the resulting page? What do you think? Kind regards, Sophivorus (talk) 12:44, 17 May 2021 (UTC)Reply[reply]

Sure that looks good - we may just want to make it in the past tense - e.g. "designed" and "prototyped" etc for doing the color coded bullet points. - Thanks Joshua Joshua Pearce (talk) 12:48, 17 May 2021 (UTC)Reply[reply]
Thanks, that makes sense, I just updated the tense. I also included a "verified-by" field to preserve the data of who did the verification, see for example Hammer, cheers! Sophivorus (talk) 13:00, 17 May 2021 (UTC)Reply[reply]

Reason for the unusually high traffic of Energy Conservation with Open Source Ad Blockers[edit source]

Hi, how are you?? I've known for some time that one of your pages, Energy Conservation with Open Source Ad Blockers, has been the top performing page of Appropedia for many months! It actually triples the traffic of the second best performing page! So I've been wondering about the cause and did some googling to try to find out. My guess was that maybe uBlock Origin was linking prominently to your page, but I couldn't find any evidence of this (btw, due to your research I switched to uBlock Origin). So anyway, today I thought that maybe I should just ask you! Do you know the cause?? Thanks!! Sophivorus (talk) 00:47, 12 November 2021 (UTC)Reply[reply]

It is a combination I think of it being a topic that is interesting to the greatest number of people (e.g. normal everyday people not into sustainability, etc.) , the few press releases we did with it - and continuous promoting of it. Right now - working very hard to get To Catch the Sun to that level. - Joshua Pearce (talk) 14:30, 12 November 2021 (UTC)Reply[reply]

Template:Pearce-pubs[edit source]

Hi Joshua. These templates are hindering a lot of the traffic to these pages. Would you be up for us finding an alternative for them? We can leave them as is, but all of Appropedia is moving towards standardized templates and would love it if other poeple could use yours as examples for their work. It doesn't have to be what I edited so far, but would love to see what works best.—Emilio (talk) 02:12, 2 December 2021 (UTC)Reply[reply]

Yes that is fine - whatever you did last time broke the pages on a normal computer so I just reverted it. Is there anyway that we can make them look decent for both audiences?--Joshua Pearce (talk) 10:44, 2 December 2021 (UTC)Reply[reply]
