==Open-source syringe pump==

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. --[[User:J.M.Pearce|Joshua]] ([[User talk:J.M.Pearce|talk]]) 10:54, 11 December 2014 (PST)

== GreenAT project==

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 http://www.appropedia.org/Solar_water_disinfection_system_with_solar_heating#Solar_Water_Disinfection_System_Construction .  Thank you very much.

== Industrial symbiosis and industrial ecology ==

Hi Joshua, 

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

I was just chatting with Wikipedian and Urbepedian Chaerani{{w|User:Chaerani}} 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. --[[User:Chriswaterguy|Chriswaterguy]] &middot; <small>[[User talk:Chriswaterguy|talk]]</small> 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. --[[User:Chriswaterguy|Chriswaterguy]] &middot; <small>[[User talk:Chriswaterguy|talk]]</small> 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.. [[User:Chaerani|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.

== AAEA ==

: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. --[[User:Chriswaterguy|Chriswaterguy]] &middot; <small>[[User talk:Chriswaterguy|talk]]</small> 09:28, 28 October 2007 (PDT)

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 - 

--[[User:J.M.Pearce|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! --[[User:Chriswaterguy|Chriswaterguy]] &middot; <small>[[User talk:Chriswaterguy|talk]]</small> 22:22, 6 December 2007 (PST)

== Article count and Spanish translation ==

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,

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.

Thanks--[[User:Doaa|Doaa]] 11:50, 11 April 2008 (PDT)

== Changes to Appropedia ==
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<br>
- 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.<br>
- 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.<br>
- 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.<br>
- 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.<br>
- You should be able to automatically go to the classic view (this should be an option within preferences).<br>
- 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?<br>
- 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)<br>
<br>
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.
<br>
Cheers,<br>
Peter

== copyvio ==

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! --[[User:Chriswaterguy|Chriswaterguy]] 23:49, 13 January 2010 (UTC)

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?

==AT CAD team==
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.

::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.

==Effect of snow on PV's==
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==
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==
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, ...)

Your students use them on their own project pages, but I didn't find them selected and collected anywhere. Perhaps some of your students might be interested in starting a project along the lines of the environmental songs page, where they assemble galleries like at [[Engr305 Appropriate Technology Projects]].

== Kit price ==

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==
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 http://www.appropedia.org/Open_design_water_heater )

== Openoffice and libreoffice ==

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. [[User:Joeturner|Joeturner]] 10:38, 15 January 2013 (PST)

== Solar sludge treatment ==

Sorry to post again, I'm thinking about the science behind sanitation interventions, and I was wondering if it was worth putting [http://sanivation.com/so-does-this-solar-concentrator-thing-kill-helminth/ this solar concentrator] as a page for appropedia.  Is it scalable? Is it technically any different to a solar oven? [[User:Joeturner|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? [[User:Joeturner|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.

== Old student page ==

I moved this to the incubator - [[Appropedia:Incubator/Charcoal Making for Small Scale Enterprises]]. Hope that's okay. The links could be useful for developing an article. --[[User:Chriswaterguy|Chriswaterguy]] 20:12, 13 April 2013 (PDT)

== cleanup AT Sourcebook  ==

Hi, care to weigh in at [[User talk:RichardF#cleanup AT Sourcebook]]? :-) --[[User:RichardF|RichardF]] 08:07, 25 April 2013 (PDT)

I now have the basics working for an [[AT Sourcebook]]:
* Main Talk page (Level 1) usage instructions ([[Talk:AT Sourcebook/Usage]]‎) 
* Section subpage (Level 2) - e.g., [[AT Sourcebook/Forestry]]
* Citation subpage (Level 3) - e.g., [[AT Sourcebook/Forestry/Agroforestry Species: A Crop Sheets Manual]] & [[AT Sourcebook/Forestry/Practical Guide to Dryland Farming: Planting Tree Crops]]
* Layout page - [[AT Sourcebook/Layout]]

Let me know what you think. --[[User:RichardF|RichardF]] 20:35, 26 April 2013 (PDT)

At this point, I have the basic mechanics worked out. So, my question to you is, do you want any changes to the citation layout page ([[AT Sourcebook/Layout]]), such as changing the display or adding parameters? --[[User:RichardF|RichardF]] 07:45, 27 April 2013 (PDT)

I noticed the first [[Wikipedia:Help:Template#Problems and workarounds|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 [http://www.appropedia.org/index.php?title=AT_Sourcebook/Forestry/Practical_Guide_to_Dryland_Farming:_Planting_Tree_Crops&oldid=239102 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. --[[User:RichardF|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. --[[User:RichardF|RichardF]] 07:32, 29 April 2013 (PDT)

Thank you for the link to the bolt.  We are printing out a hold that we found from the link.

Well thank you for your input anyways.  As a matter of fact, we are printing out this hold http://www.thingiverse.com/thing:493709

== The Tesla announcement and snowy places  ==

I was wondering whether with the new Tesla Energy (by now...) placed in heavy snow fall regions of Canada can expect to benefit?

I consider interesting a developer to build a potentially off the grid conominium project in Montreal using the Tesla rechargeable "Powerwall" batteries.

Any news, new developments re. the feasibility of it in Quebec and similar (or worse) snowfall regions in Canada...

== Have you thought of adding translation like we do on the SCInet Wiki? ==

You'll see the translation links at the top of every page:

http://solarcooking.org/Chile 

I've gone through the massive list of Google translation languages and picked out the 34 languages that cover the greatest number of people. You can grab the code from here: http://solarcooking.org/Template:GoogleTranslateLinks

Note that we are linking to an interim page to record how the links are used and on which pages. You will just need to change the target URLs to point directly to http://translate.google.com.
