I was wondering whether anyone knows whether there are ecological and simpler alternatives to PCB boards. I was thinking about ], ] and the like yet am not sure whether environmental and whether any difficult circuits can be made with this. Wafer-level packaging (this is I believe only used with certain components) can also sometimes? be used. Also not sure whether very environmental (presence of glues, and hazardous materials as certain plastics, ...). I also heard about the Tin-Lead ban, see ] which has introduced the creation of alternatives (eg SnAgCu, SnCu and Sn alone). I also heard about
anisothropically conductive glues (these are not environmental) and isothropically conductive glues (respectively ACA and ICA), glues for flip-chip assembly... yet not sure whether truly ecologic and whether its any durable.

Perhaps Sn alone is most appropriate? This will need to be checked and further compared dough. See http://www.europeanleadfree.net, http://www.imec.be/IMECAT/, http://www.imec.be/IMECAT/documents/16_2004_IPC_Frankfurt_Vandevelde_paper.pdf

A appropriate solder and soldering method should be the following:
* easy assembly and disassembly of board, components and solder (so best no alloys as this reduces options with melting the parts off)
* no etching (this would promote loss of soldering material); instead direct application of paste eg by hand soldering as in reflow soldering or automated (with workshop pick&place robots)

An alternative is the use of organic materials (which are thus consistent to cradle-to-cradle design). Certain (not all!) ]s can be used. Examples are ]. However, this approach is not yet suited today to make any durable or more advanced circuits.

Also, could any other techniques as flow soldering, E-blocks, FPGA, EasyControl I/O, ... be used. E-blocks also uses flowcode as a coding language. Not sure whether this is easy to learn (aldough most coding can be simply downloaded if open-source).

In addition, a suggestion on the LED-lamps. These are I believe quite expensive. In order to decrease price, I was wondering whether LED's may be made DIY (they are composed of a die, lens, cooling body and connection wires. Compounds used include aluminum, indium, gallium, phosphor, nitrogen. Especially low-power leds seem easy to build, high power ones may?? be achievable using techniques as Lumiramica (uses phosphor plates instead of powder).

An alternative is the procuring of mere high-power LEDs (eg Lumileds Rebel Led, Osram Opto Semiconductors Golden Dragon, Cree X-lamp, ...)and installing them yourself with the .

==Open-design circuit board oven and solder robot==
The may be used as is (or after modification) with the Sn solder (or other soldering method) noted above to solder boards ecologically and appropriate.

::Note that this open-source project demonstrated how easy it is to implement controlling the temperature of ovens. Perhaps that a similar temperature control may be integrated in the recasting of materials. In the document made by Ingénieurs Sans Frontières it was described that casting was done "on sight". To make solder for these sensitive equipments, perhaps controlled temperature casting is better as it may allow a better purity of metal (improving the performance of these sensitive devices)

for the soldering itself, I was thinking about a open-source soldering robot (which can be probably made with a diy embedded (low-cost) microcontroller (to make a embedded computer with output devices (movable soldering syringes. This primarily as I have doubts about the local workers performing this very precise and difficult job. The local workers are probably more suited to gathering the source materials (metals, ...)

==Component tester==
As described above, with component boards as strip boards, easy replacing/repairs of devices are possible (allowing the repair of broken boards by replacing certain components, rather than trowing away the entire board alltogether). For this, a simple? voltage meter is needed to test the components individually (eg whether they still let the power trough). This may be used herefore

==Disassembler device==
Besides an oven and solder robot, an easy open-source board disassembly device would be appropriate. This would allow boards found on the junkyard (which are thus completely broken; having no more working components) of being effciently disassembled. The solder, board and components can then be easily seperated and reused (solder and metals can be recast, chemical components may be derived from large amounts of diodes, and other known components). The chemical substances and amounts are known to be in each type of component (eg diodes, leds, ...) and may therefore still be recovered if they are all seperatly detached and sorted together.

==Open-design washing machine==
A open-source washing machine should be created. The washing machine is to have a induction engine for the drum and a brushless DC engine for pumping the machine dry after the wash. It probably best uses (the technology of; buying the modules from the company directly may be expensive) the Motion SPM in SMD or Tuny DIP housing. see and
Perhaps water-saving features may be added (see ]) Cleaning agents used should be eco-friendly; see ]

Schumacher

Didn't E. F. Schumacher invent the term in his book "Small is Beautiful: Economics as if People Mattered"? Spalding 02:39, Oct 25, 2004 (UTC)

“Smart Village” (Rural Information Technology Center) in Malaysia

I came across this reference: "The “Smart Village” (Rural Information Technology Center) concept being tried in Malaysia to make access to the relevant information and education based on cost efficient high-tech in rural areas... " - [http://tojde.anadolu.edu.tr/tojde18/notes_for_editor/note2.htm Information and Communication Technology for Poverty Reduction]. (It's a pretty general article, not much that's concrete).

I can't find any other reference to this Malaysian program (apart from quotes/mirrors of this original article. It could be something to look out for. --Singkong2005 05:03, 11 May 2006 (UTC)

Solar bowl section

I removed this (below), and put part of it (starting The Auroville community) in the Solar cooker article. That part is better suited to the solar cooker article, and the earlier two sentences don't seem to be necessary to the appropriate technology article as it now stands. --Singkong2005 03:22, 24 May 2006 (UTC)

In one view, appropriate technology is technology considered to be fitting for one or more specific uses in a particular locality by members of a particular community (taking into account environmental or biological factors). One example is provided by an instance among the many possibilities for direct use of solar energy in India. The Auroville community (at Pondicherry, India) has installed a huge “solar bowl” employing solar energy for cooking. This is a south-facing 15-meter diameter mirror bowl that focuses sun rays on a cylindrical boiler. The bowl follows the sun's position by means of a computerized tracking device. With this boiler, steam at a temperature of 150°C can be generated, which is then utilized to cook two meals a day for 1,000 people, on clear days. Another large solar cooker of essentially similar concept is in use at Mt. Abu in Rajasthan, India. Obviously, these have been put in place in notably sunny climates.

Proposed merge from Intermediate technology

Support. Intermediate technology in practice is a synonym for appropriate technology, and not used very often. It was originally used with a particular explanation by EF Schumacher (if I've got my facts right) but this can be deal with in a paragraph or two here. This article is getting long, but a better way to deal with that might be to make a new page for the section Some appropriate technologies. --Singkong2005 03:27, 24 May 2006 (UTC)

Information and communication technology - removed sentence

I removed this: See also : LMDS, satellite internet and broadband internet for rural areas. There is some relevance to rural settings, especially in Broadband Internet access#Technology; however, it doesn't seem like appropriate technology (for developing countries/regions), to me. --Singkong2005 12:18, 31 August 2006 (UTC)

Village Earth link

I've removed the link to the Village Earth's Appropriate Technology Wiki Project. I went there, and looked through each of the 28 categories. There was a total of four articles, one of which was basically "about us". I really don't want to be unkind, but "smaller and less active" is one thing, and "practically empty" is another entirely. To be fair, the categories themselves had a bit of background text, which could arguably count as small articles, but still... I think it'd make a good addition here if it ever takes off, but it clearly hasn't come close to doing so yet. Waitak 11:45, 7 November 2006 (UTC)

Good call. I didn't want to do it as I am very involved with Appropedia, so it could be seen as my bias. But now the VE Wiki has merged with Appropedia, so it's all good. --Chriswaterguy talk 07:37, 1 May 2007 (UTC)

Complementary concept

Sometimes more expensive and advanced technology is used in developing countries than in wealthy countries because of a lack of infrastructure. For example, mobile phones, satellite television and and solar cells have caught on earlier in some developing countries. I don't think such a trend would be classified as "appropriate technology", but the concept is certainly related I think. Is there an accepted term for this development and have there been serious studies of it? Thanks.--Pharos 08:20, 8 January 2007 (UTC)

I'm glad you wrote this, it is also related to the meaning of intermediate technology. The definition of appropriate technology given in this article (in my opinion) could be slightly better organised (will have a go at it at some point). Appropriate technology is any technology which is most suitable to the circumstances of where it is implemented. So mobile telephone networks are most certainly appropriate technology in Africa - just as coal-fired powerplants are appropriate technology for providing electricity to Nairobi (because little windmills certainly wouldn't be). It is simply not true that appropriate automatically means basic or simple - it means exactly what it says - appropriate.

The reason Schumacher used the term intemediate is that he specifically meant more basic and simple technology which was appropriate for "The South", and particularly the rural South, where the majority of the world's poor then lived (now they are all moving to the cities, so the situation is somewhat different).

The following is taken from the Practical Action website:

"An ‘appropriate technology’ is one that enables people to satisfy their basic needs while making the most of their time, capabilities, environment and resources.

To judge for yourself whether a technology is appropriate ask yourself whether it:

  • meets the needs of both women and men
  • enables people to generate income for themselves and their family
  • can be designed, improved, managed and controlled by local people
  • is affordable
  • uses local skills and materials as much as possible
  • has a limited impact on the environment ... "

Tkn20 00:46, 9 January 2007 (UTC)

It certainly needs work on the definition, and I'd love for someone else to do it! I've put in quite a few hours on this page and related pages, but in terms of main body content rather than the introduction and definition. Partly because that kind of writing is not my strength, and also I think it would take quite a bit of research to get a good "verifiable" definition. The term is used in quite a range of ways. Yes, the basic meaning is simply a technology that is appropriate, but it is generally used to refer to those technologies appropriate to a developing setting - especially when used as a term, rather than just two adjacent words in a sentence. At least, that's my observation. So it can be used for sophisticated technology, but is less often used for something appropriate specifically to a wealthy community.
Btw I was very pleased recently when told by someone from Engineers Without Borders (Australia) that this was a great article. --Chriswaterguy talk 07:32, 1 May 2007 (UTC)


Individual Submittal on Appropriate Technology Ideas....(includes Reference)

I would like to document and incorporate by reference several apparent appropriate technologies. (See the following link: http://www.commondreams.org/archive/2007/08/28/3455/ )

This link discusses several appropriate technologies in posts that i authored including: "battery banks"; "'mirrored' solar panel design"; and "neighborhood waste water treatment plants".

i would love to see more individuals submitting their own ideas on appropriate technologies. Some of these ideas will "take-off" for sure. Don't you think?

Not suitable for Misplaced Pages - see WP:NOT. I would propose an Appropriate technology wiki. Disclaimer: I'm involved in that wiki. This is consistent with Misplaced Pages policy though - no original research here, but it may be welcomed on another wiki. --Chriswaterguy talk 20:47, 17 November 2008 (UTC)

Use of wikipedia to facilitate development work

I was in Tanzania this summer working on energy efficient cooking stoves, and realised part of the way through my time there that it would be really helpful if the local people at the NGO I was working with could find really accessible information on the internet for themselves, about specific technologies, including technical information about how to implement them. One of my project partners suggested that wikipedia would be a really good centralising place to put such information, of which there is a lot on various NGO websites. Would it be appropriate to start a project to put useable, technical information about things like energy efficient cooking stoves, brick firing kilns, water harvesting systems on wikipedia, as part of the sustainable development portal? Twer-el-lel (talk) 22:25, 7 January 2008 (UTC)

Sounds great to me! :-) Of course, there's more than one way to accomplish your basic objectives. Articles can be highlighted in selections boxes. They also can be linked in topics and categories boxes. Some articles might lend themselves to be organized within lists as well. I expect some of the existing development projects would be good places to continue discussing the possibilities before another project is started. RichardF (talk) 22:41, 7 January 2008 (UTC)
Really glad to hear other people thinking about this! Misplaced Pages is indeed part of the solution, and that's what led me to create Category: Appropriate technology category and subcategories, and various articles in those categories.
However I was convinced to help start up a separate wiki as an additional resource. Misplaced Pages only accepts certain types of info, so for comprehensive information including how-tos, project information, research, experience and knowledge which doesn't meet Misplaced Pages's criteria (being verifiable and notable), as well as networking, please check out Appropedia! It's the major wiki for international development, appropriate technology and sustainability. (More about the scope at Appropedia: Project: Appropedia is different from Misplaced Pages.)
In terms of the project to put info on Misplaced Pages - see Misplaced Pages:WikiProject International Development (ah, I see you've already joined - excellent) But as noted, this is about adding encyclopedic info to Misplaced Pages. If in doubt, or if you want to go beyond those limits, use Appropedia. Looking forward to hearing from you both! --Chriswaterguy talk 23:48, 13 February 2008 (UTC)
Yeah, I am already providing some practical info on the Wiki (look to my contribs for reference). However, please put zero-emission alternatives first instead of things like biomass/biofuels powered alternatives. (check out my blog for some insights here; see my user page at wiki). Also note my microgeneration article, and links to sites as PESwiki, wikia.com and howtopedia.org (the latter can also provide a base of operations for info). Emmh,... if you see any possibility for me to be employed at your org in Tanzania (I prefer Misali,Pemba or Zanzibar) let me know. PS: I also inmediatelly updated the AT page somewhat. Perhaps that some organisations noted in my intentional community-page may come in handy (This page may however be better moved to "alternative society", yet needs extra references, ... to do so). --KVDP (talk) 15:28, 14 July 2008 (UTC)
Misplaced Pages is meant to be NPOV, and isn't really the place for making judgments on biomass vs zero-emission alternatives - that's really for other wikis, like Appropedia or the ones you mentioned. I'll check out the articles you mentioned.
The Appropedia Foundation is still working on funding, and hasn't employed anyone yet (even the founders). Sorry! --Chriswaterguy talk 20:12, 17 November 2008 (UTC)

Explaination on environmental requirements to qualify for AT + foods/wood from biodiversity hotspot free zones

Is everyone OK with letting wood and foods derived from biodiversity hotspot-free pass for Appropriate technology. Examples are rice from places as China (eg instead of Sri Lanka), and the preference for grain crops as wheat, spelt, barley, ... (and derived foods as toast); as they come from northern (biodiv-hotspot free) zones. Also, tea from biodiv-free (eg Argentina), wood from canada instead of eg Brazil, and the marking of most tropical fruits and certain other (root) crops (eg certain yams) as to be abandoned.

Also, a section explaining why the environmental friendlyness is important should be added: explain herein that climate change will mostly affect the developing nations (with Africa in the lead).

Thanks KVDP (talk) 15:29, 14 July 2008 (UTC)

If there are WP:NOTABLE sources discussing Appropriate technology in this way, then certainly it should be added, though probably as one perspective, as not all ap tech folks have the same emphasis.
If not, then as I mentioned above, it would be fine at another wiki such as Appropedia, (e.g. at Appropedia:Jottings on appropriate technology or a new page), as the criteria are different. But the only info that's really suitable at Misplaced Pages is referenced information. --Chriswaterguy talk 20:29, 17 November 2008 (UTC)

Transwiki the non-encyclopedic content?

Should we transwiki the non-encyclopedic content? Well, obviously we should, but the question is, which of it is non-encyclopedic? My suggestion is, anything that has been tagged as unreferenced for a significant length of time, and I think at the moment that this is most of the article. So I'm proposing reducing this article to a basic description, with additional content on a different wiki.

I added a lot of content to this article, long ago (esp late 2005 early 2006 I think). But in hindsight, there's a lot of judgment in it, as to what constitutes an "appropriate" technology. So I'm inclined to remove large portions of this article, where it is unreferenced, and place it on Appropedia. (I'll probably use Special:Export so it preserves the page history.)

It goes without saying that anyone may use the content elsewhere as well, but the important thing is to make use of this (IMO) valuable content on a suitable sustainability and development oriented wiki. --Chriswaterguy talk 20:43, 17 November 2008 (UTC)

Inclusion of other pumps

Should the shadoof, sakieh and the bucketpump (see this website) be included in "water supply"? I'm not sure whether they provide better efficiency and/or low cost to produce over treadle pumps. Please look into it and add if they still have some advantages over treadle pumps, if not never mind, as things would become unnecessary complicated. —Preceding unsigned comment added by 81.246.181.231 (talk) 10:11, 12 December 2008 (UTC)

Also, ISF has also made a VHF/LV transformer to allow a village to use power from high voltage lines. Perhaps this can also be included (may allow villages to supply power from micro-generators to the net for cash; known as net-metering ?) 81.246.181.231 (talk) 12:29, 12 December 2008 (UTC)

Perhaps the sickle, Kama, and some survival knifes with cutting scharisteristics such as the khukri may be considered appropriate technology. Kirpi and foot plough's also seems useful technology

Btw: I was wondering whether anyone knows the type of hatchet seen in "The Nativity Story" (in Mary's village). I guess that this type of hatchet (as above) is multifunctional. Don't know name dough nor that it is indeed multifunctional. —Preceding unsigned comment added by 81.246.183.235 (talk) 15:27, 28 December 2008 (UTC)

Water supply

I suggest adding a variant of the picture Water system with cistern

, where the pressure vessel is removed and the cistern itself works as a pressure vessel. This would allow the system to be build DIY (rather than needing to buy a pressure vessel or weld your own pressure vessel casing. Please include in article.

Perhaps diy water towers can also be included, as they allow multiple users to take advantage of a single system (reduces cost). However, the downside would be that if the tower fails, part of or the entire village would be affected. If this happens (especially in remote arid/desert-like locations, repairs will go slow aswell (water being important to work in order to make repairs) and replacement parts may not always be available. Also, another thing is dislike in water towers is that they are outdated and somewhat inefficient (a pump is required too to pump the water up, its only after the elevation that it can works without electricity or extra pumps).

Hair removal machine

Perhaps hair removal and laser hair removal machines can be presented as appropriate technology (increase hygiene and thus decrease disease, ...) see for example the Rio Salon Laser Scanning Hair Remover. This machine or a low-cost derivated machine can be proposed (home-use, 200£). 81.246.183.119 (talk) 12:34, 18 February 2009 (UTC)

Direction where AT should move towards

A section can be included with the section in which the recycling of materials is explained. This section can include references to shows as the Salvage Squad, Scrapheap_Challenge and Junkyard Wars. Also, a reference to Burning Man festival can be made. Ideally, cities will need to be constructed entirely from waste material, similar to what Biotecture does. Perhaps for some visual impressions, references to Flushed away (see http://kids.nationalgeographic.com/Stories/MoreStories/Flushedaway ) and The Fifth Element can be made.

International language and electricity system

A simplified english as the only spoken language is an appropriate technology and can be implemented in appropriate technology documents and books. Also, standards and rules to only use one type of mains electricity system (amount of volt & frequency) is best used to allow the building of internationally invariable electric devices and machines. see http://en.wikiversity.org/Juridical_national_measures_on_climate_change#Optional_digitalisation_of_city_communal_services

Chainless bike with airless tires

Perhaps bikes without chains (eg shaft-driven or hydraulic bicycles) and Airless tires are more appropriate bicycles. Would reduce malfuntionings and more difficult bike repair trainings required today. Perhaps tubeless wheels can be used as a basis in which latex can be poured. —Preceding unsigned comment added by 81.246.163.71 (talk) 10:55, 27 February 2009 (UTC)

Wafer-level packaging (this is I believe only used with certain components) can also sometimes? be used.

Also, could any other techniques as flow soldering, E-blocks, FPGA, EasyControl I/O, ... be used. E-blocks also uses flowcode as a coding language. Not sure whether this is easy to learn (aldough most coding can be simply downloaded if open-source).

Open-design circuit board oven and solder robot

The Elector SMT reflow oven may be used as is (or after modification) with the Sn solder (or other soldering method) noted above to solder boards ecologically and appropriate.

Note that this open-source project demonstrated how easy it is to implement controlling the temperature of ovens. Perhaps that a similar temperature control may be integrated in the recasting of materials. In the document made by Ingénieurs Sans Frontières it was described that casting was done "on sight".

For this, a simple? voltage meter is needed to test the components individually (eg whether they still let the power trough). This open-source elektor meter may be used herefore

Disassembler device

Besides an oven and solder robot, an easy open-source board disassembly device would be appropriate. This would allow boards found on the junkyard (which are thus completely broken; having no more working components) of being effciently disassembled. The solder, board and components can then be easily seperated and reused (solder and metals can be recast, chemical components may be derived from large amounts of diodes, and other known components). The chemical substances and amounts are known to be in each type of component (eg diodes, leds, ...) and may therefore still be recovered if they are all seperatly detached and sorted together.

Open-design washing machine

A open-source washing machine should be created. The washing machine is to have a induction engine for the drum and a brushless DC engine for pumping the machine dry after the wash. It probably best uses (the technology of; buying the modules from the company directly may be expensive) the Motion SPM in SMD or Tuny DIP housing. see Energy Saving through Motor Control and Motor app gains efficiency with electronic control Perhaps water-saving features may be added (see Washing_machine#Washing_machine_milestones 2008 Berkeley washer) Cleaning agents used should be eco-friendly; see Natural cleaning product
