  • Functioning, maintenance and regeneration of lead-acid batteries  + ('''Equipment''': Choose your battery caref'''Equipment''': Choose your battery carefully according to the intended use.
    Never mix new and used batteries.
    Never mix batteries of different technologies.
    Correctly and solidly install the wiring of your battery bank to avoid fires.
    Regularly check the connectors if they are subject to vibrations.
    *'''Detection and Prevention of Deep Discharge''': Battery life is directly related to DoD or depth of discharge. It is, therefore, very important to prevent any discharge over 50% !'''
    **How to know the level of charge (SoC)? ***Simply measuring the voltage does not suffice as several factors affect the battery voltage. ***A [https://www.victronenergy.fr/battery-monitors battery monitor] must be used. It calculates not only the voltage but also the charge and discharge currents, which allows the state of charge to be calculated in real time. **How to avoid deep discharges? ***The idea is to control the level of charge (SoC) and to disconnect the consumption loads as soon as they fall below a certain level. ***Use a battery protector/[https://www.victronenergy.fr/battery_protect/battery-protect Battery Protect] or a configurable solar charge regulator, for direct current (DC) equipment. ***Use the dry contact relay (voltage-free relay) of your battery monitor if it is equipped with one. ***Set the low battery voltage threshold on your inverter for alternating current (AC) equipment (read the instructions carefully). *'''Pay attention to the temperature: ''': This factor has a very important influence on the life of the batteries. It is very important to keep the batteries at “cool” temperatures, around 20°C. **Technical roome : Always choose the coolest room or location. Never leave batteries exposed to direct sunlight. If the place is still too hot, one should consider cooling ventilation of the room or the battery container. **Aeration and ventilation : Always keep space between the batteries (about 5 cm), do not put them against each other. If the batteries are inside a battery box or in a cabinet, there must be air circulation. **Temperature compensation: When the temperature exceeds 30°C or is lower than 10°C for a long time, it is necessary to change the charging voltage.
    Battery not in use – Self-discharge: When a battery is not in use, it slowly discharges. This phenomenon depends on the type of battery and the temperature. o An unused open battery must be recharged every four months at room temperature (between 10-25°C). o An unused open battery must be kept permanently charged in temperatures below 0°C. o Sealed batteries can be left for up to 6 to 8 months without recharging at ambient temperature. o When a system containing batteries (RV, car, etc.) is not used for a long period, disconnect the batteries to avoid leakage currents.
    *'''Correct charging voltages''': Never recharge the batteries with a voltage higher than that recommended in the manufacturer's data sheet. Use a charger with at least 3 charge stages (Bulk, Absorption, Float).
    *'''Correct charge/discharge current''': '''It is recommended '''never to charge or recharge''' lead batteries at '''more than 0.2C''', i.e. 20% of the capacity of the battery bank (ex: 20A for a battery bank of 100Ah).

  • Setting up a Local Community  + ("The islands of a growing archipelago" Es"The islands of a growing archipelago" Establishing a link between territories, as close as possible to needs is the be-all and end-all of the low-tech approach. Digital distribution channels help to raise awareness and to get to to know this approach, however then you have the people who put it into practice. Local communities made up of beginners, experienced and/or expert citizens play this leading role in local dissemination, collaborating with the actors in their territory. They are equally interlinked with each-other in orde to share and exchange resources, ideas, discoveries and sound practices.

  • Ram pump  + ( #When priming, water flowing into the inl #When priming, water flowing into the inlet line flows into the weir through the primary valve. #The acceleration of the water causes the primary valve to close suddenly. #The water column is suddenly braked and generates an overpressure in the pump casing (water hammer), which opens the internal valve. #Under the effect of this overpressure, water flows into the balloon (and the discharge duct), compressing the air volume until the pressures are balanced. #The pressure reversal closes the internal valve. #The water trapped under pressure in the balloon empties into the discharge line until the pressures are balanced (determined by the height of the pipe). #The closing of the internal valve has caused the pressure to drop, so the primary valve opens again. A new cycle begins.... Without accident, this process is perpetually renewed as long as it is supplied with water.

  • The how to of how to's  + (''' 1 - Tools''' A camera, a microphone, ''' 1 - Tools''' A camera, a microphone, SD cards, batteries, a tripod. Check before use the state of your tools : SD card with sufficient disk space, battery charged, etc. ''' 2 - Location of the movie''' Choose where does the action takes place, in order to have a good sound quality and good luminosity: - Indoor, beware of the lack of light and artificial lights, that will impact your video quality. Think of fridges, clocks as well, that could create parasite sounds. These will be disappointing for the spectator watching your video. - Outdoor, beware of backlighting and the lack of light. Concerning the sound, the wind is fatal. Protect your microphone and its exposure ! "In both cases:" - Be careful that no big light pits are in your field of view. - Avoid too big spaces, the backplane should rather be short. - Filming during the day is highly recommended. At night, you'll get granulas on your images. ''' 3 - Positionning of the camera''' In order to know where to place the camera, ask the actor what he's going to do at each step. It is therefore easy to place the camera without being annoyed with his hands. On the workbench should only be present the material used at the precise step. This permits not to be visually polluted. ''' 4 - Scenes''' "Dissect steps" : Film one scene per step, if possible. - Vary short and large scenes to air the video. - For explicative scenes (explanation of a step, of the context), prefer large scenes. - For active scenes (filming the action), prefer short scenes. - It is highly recommended to film two frames per action. - Head to foot framings are not recommended, prefer middle range frames or short frames. - When someone is speaking, do not "cut his head off" during framing. Let an empty space above him. - Avoid to place the person right in the center of the frame. Putting him on the side will bring dynamism to your scene. - Filming static scenes is highly recommended to avoir any shaking. - Put the camera on a tripod or on something static. ''' 5 - Focus''' For the focus, check whether the camera is on automatic or manual mode. - If it is on automatic, well check that the camera is focusing on the action and not on the person head. - If it is on manual, set the focus on the action before starting to film. ""Example"": "Here, I'm going to melt the white wire on the + pole...". We need here a close plane, we focus on the object to melt, and we check that our hands are not between the object and the camera when we film. ""Be careful"" : For tutos realized with smartphones, the difficulty is to realize static scenes. Put the phone on a stable, static place during the whole sequence. ''' 6 - Filming in order to edit the video''' - Don't tell yourself that mistakes can be rectified at video editing. - Avoid to film in black and white or vertically. - Launching the video recordings, let a dead time before action starts or discussion begins in order to facilitate video editing. - Make simple rushes for get an easy video edition. ''' 7 - Content''' The video content will tighly be linked to the written step by step. "Context video : (2 minutes)" - Present the low-tech and its economical, environmental, social or other interests. - Present an issue solved by the low-tech (problematic and solution) - Do not hesitate to start from a larger context to a local one, or even personal one. - It is important to choose with the speaker, what is going to be said. Le scene will be explicative, so prefer a large frame scene. - Add cut-scenes (action) for this part don't be only a monolog in front of the camera. Think as well to make action scenes "on the field", that will be in concordance with the context. "Fabrication video : (5-10 minutes)" Ask yourself which kind of video is preferable to realize. Notably when speaking of explanations : will they be voice-overed, lived, or subtitled ? - Beware of hands between the camera and the action. - Always keep in mind that everyone has to understand the action. For this, it can be interesting to explain : "I'm doing this action for this reason, with this material that I got at this place ..." - Do not forget to mention safety intructions. "Dissect the fabrication in several key-steps:" - The functioning: present the functioning principle of the low-tech - The material : materials and tools necessary for the fabrication - The fabrication : dissect every step, one scene for one action, and explain them precisely, speaking loud and articulating. - The use : scenes on its situation. - Advices : It is possible to finish the video giving some advices.e to finish the video giving some advices.)

  • Ceramic water filter  + (Clay: L'argile constitue le matériau de bClay: L'argile constitue le matériau de base de l'élément filtrant de l'eau. Un pot d'argile permet un mouvement extrêmement lent de l'eau à travers les pores naturels qui existent entre les plaquettes d'argile cuite. La taille de ces pores a été mesurée (au microscope électronique) entre 0,6 et 3,0 microns (μm). Ils sont capables d'éliminer la plupart des bactéries, protozoaires et helminthes (Lantagne, 2001a), ainsi que la saleté ou les sédiments et la matière organique. L'argile utilisé pour faire de la poterie classique peut convenir à la production de filtres à eau. Toutefois, la conductivité hydraulique et la taille des pores peuvent varier considérablement selon le type d'argile, potentiellement au point de ne pas convenir en ce qui concerne les débits et/ou l'élimination microbiologique (Oyanedel-Craver et Smith, 2008, in Lantagne et al, 2010, [[https://pubmed.ncbi.nlm.nih.gov/20162486/ 1]]). Une forte teneur en sable ou en limon dans l'argile peut réduire les réticulations de l'argile et affaiblir la structure du filtre . D'autre part, une argile trop raffinée (particules plus petites) a une plus grande capacité de rétention d'eau et est donc plus sujette au rétrécissement et à la fissuration lors de la cuisson.
    Comme les caractéristiques de l'argile sont un facteur critique dans le succès ou l'échec de la production de filtres à eau en céramique, il est recommandé d'étudier minutieusement les sources et les types d'argile potentiels avant d'engager des ressources importantes. Retrouvez le document de Potters for Peace détaillant le protocole de test de l'argile dans la partie "Note de Références" [18]
    *'''Le matériau combustible :''' Des matières organiques " combustibles ", telles que de la '''sciure de bois''' ou des '''balles de riz moulues''', sont ajoutées au mélange d'argile. Lorsqu'il est exposé aux températures élevées du four, le "matériau combustible" brûle, laissant derrière lui des cavités dans l'argile cuite. L'eau se déplace plus facilement dans les cavités que dans les pores de l'argile. Par conséquent, la présence des cavités diminue la distance que l'eau doit parcourir à travers le substrat d'argile, et augmente donc le débit global du filtre.
    Il est important d'effectuer des tests avec vos matériaux. Le rapport entre l'argile et le matériau combustible est important pour établir le débit et donc l'efficacité des filtres.
    *'''L'argent colloïdal''' : L'argent colloïdal est une solution de nanoparticules d'argent en suspension et d'ions argent. Il est utilisé comme désinfectant naturel dans la médecine depuis de nombreuses années. Bien que les mécanismes exactes de destruction des bactéries ne soit pas encore tout à fait compris, il semble que l'argent colloïdal cause une rupture des parois cellulaires des bactéries puis se lie à leur protéines troublant ainsi leur fonctionnement [[https://www.hwts.info/document/8bda3e01/investigation-of-the-potters-for-peace-colloidal-silver-impregnated-ceramic-filter-report-1-intrinsi 2]] [[https://www.hwts.info/research/1245c13a/protozoa-and-virus-disinfection-by-silver-and-copper-embedded-ceramic-tablets-for-water-purification 3]]. Aujourd'hui il est principalement produit par électrolyse. L'argent appliqué à l'intérieur et à l'extérieur du filtre est absorbé dans les pores de l'argile. Les ions d'argent sont réduits en argent élémentaire et forment des colloïdes à l'intérieur des parois du filtre. L'argent agit comme un biocide contre les bactéries lorsqu'il y a un temps de contact suffisant (=pores pas trop grand).

  • Cocedor micro gasificador  + (Se basa en el principio de la gasificaciónSe basa en el principio de la gasificación: La madera se calienta en una atmósfera baja en oxígeno, lo que permite la liberación de gases inflamables llamados "Syngas", que luego se queman en la parte superior de la estufa. El Micro-gasificador se enciende desde arriba. El aire primario introducido en la parte inferior pasa a través de la masa del combustible y permite mantener un fondo de pirólisis que desciende a medida que se liberan los gases combustibles. El aire secundario se inyecta en la parte superior para proporcionar el oxígeno necesario para la combustión de los gases que se liberan hacia arriba. Se obtienen mejores resultados en convección forzada con el uso de un ventilador integrado bajo la rejilla de apoyo de combustible, pero esto necesita un suministro fiable de electricidad. La temperatura de combustión es de alrededor de 800°C, y las eficiencias térmicas oscilan entre el 30 y el 45%, dependiendo de la calidad de fabricación del sistema y de su aislamiento.

  • Low-tech Computer  + (We recommend using the Low-tech computer tWe recommend using the Low-tech computer to be able to consult Wikipedia offline. To do this, we will use the '''Kiwix''' software. This free software allows you to have the entire Wikipedia encyclopedia ('''and many other contents''') in hand wherever you are! On a boat in the middle of nowhere or even in prison, it allows access to all of human knowledge. You do not need internet access, everything is saved on your computer, your USB key or DVD. For this you will need: *Kiwix (the software) *The ZIM file with the Wikipedia content in the specific language that the user wants (for ex. French). We will present two slightly different installation options: *Option 1: Use Kiwix as a Reader The KIWIX Reader allows you to '''consult offline, without an internet connection, content packages''' (Wikipedia, TEDx, ...) in ZIM format. It is available for all major operating systems (Windows, Mac, GNU/Linux, Android). It comes as a standalone application or browser plugin. Install it and consult Wikipedia content directly on your Low-tech computer.
    *Option 2: Use Kiwix as a Hotspot KIWIX hotspot allows you to '''convert a low-cost mini-computer like the Raspberry Pi into a relay to distribute free content, without an internet connection, via a local network'''. This solution is especially useful for schools, libraries, communities, humanitarian organizations, etc. End users only need a device capable of detecting the network with the browser, they do not need to download and install anything on their device.

  • Black Soldier Fly breeding  + (The breeding environment can be made with The breeding environment can be made with various materials. For the prototype of the boat for example, we built a wooden box in which we put a plastic bin containing the waste and larvae (See photo). For example, you can use a plastic drum cut on top, or a simple plastic box. '''For the construction:''' '''1. Preparation of the boards''' *Using an electric or hand saw, cut the 6 boards to the right lengths *Sand the boards *Apply an undercoat on all sides of the boards and allow to dry *Apply a coat of wood paint and let it dry *Apply a coat of varnish (optional) and let it dry '''2. Assembly of the box''' *Using the angles and screws, assemble the boards on the bottom of the box *Using angles and screws, connect the different sides of the box *Cut out cleats to strengthen the inside of the box and attach the lid to it. *Using screws, fix the cleats on the upper part of the walls *Prepare the cover by installing hinges. *Install the cover on the box and fix the hinges '''3. Preparation of the waste box''' If the sides of your waste bin are not very high, it may be useful to put an additional barrier against larvae escape *Pass an old used inner tube all around your tray and leave a part coming out towards the inside *Staple the inner tube to the tray *Place the tray at the bottom of the box and stick it against one side '''4. Preparation of the slope''' *Cut the board in the shape of a trapezoid so that it forms a ramp when placed on the waste and joins the edge of the box at an angle of less than 45 degrees *Cut cleats to fit the external shapes of the ramp *Secure them with screws on the ramp '''5. Installation of the ramp ''' To facilitate maintenance, we put the ramp on a hinge to be able to lift it up and easily remove the bin from the waste *Install a hinge on the lower part of the ramp *Attach the hinge to the box '''6. Cutting of the holes on the box''' In order to allow the entry of flies and the exit of larvae, holes must be drilled on the sides of the box. For larvaes: *Measure the location where the ramp arrives and count 2cm high for the opening *Using a drill, make holes at the 4 ends of your opening *Using a saw, connect these holes to create an opening For the flies *On the sides of the box, drill with a hole saw about ten openings of 5cm in diameter '''7. Placing of the larvae collection box''' *Using screws, fix the plastic box under the larvae exit slot
    Make sure that the ramp is firmly fixed against the wall so that the larvae cannot fall back into the tank. If necessary, staple a bracket from the ramp to the collection box
    '''8. Laying supports (if no separate aviary)''' *Cut out pieces of cardboard boxes that are 10cm by 5cm thick. *Assemble 4 pieces with string *Attach two screws to the cleats at both ends of the box *Hang a string on these screws *Hang the egg-laying supports on the string so that they are as close as possible to the waste '''The general recommendations for the design of the living environment are :''' - Size your waste bin according to your weekly volume. Indeed, it is not necessary to have a too thick layer of substrate so it is better to be able to spread out your waste rather than stack it. - Drill holes so that female flies can come and lay eggs inside. - Place the egg-laying supports above the waste, as close as possible. These can be made of honeycomb cardboard or wooden planks separated by a pin (a gap must be left in which the flies will lay their eggs). During hatching, the larvae will fall directly into the waste. - Have a well sealed waste box to prevent larvae from escaping in case of lack of food. - Put a ramp for the exit of the larvae. It can be inclined up to 45 degrees but prefer a softer slope. As larvae tend to follow the edges of the box to find the exit, it may be good if the ramp is the full width of the box. - Avoid the ventilation holes on top to protect the substrate as much as possible from rain.
    Do not bring water into contact with eggs, they would burst!
    On the pictures, you can see the plans of the system we had validated and that works on the boat. The fly inlet/outlet holes on the top have been plugged and the aviary attached to the cover has been changed to a separate aviary, see below.

  • Garde-Manger: Pantry Storage  + (The first step in using a food-storage sysThe first step in using a food-storage system, such as the one proposed here, is for the user to question the ways in which they buy and consume. Given that food storage modules that we're going to propose below are mainly designed for raw and fresh foods, it would be complicated for the user feeding themselves with ready-made meals to benefit from the technical suggestions provided, for example. The "Zero Waste" approach, originating from Franco-American Béa Johnson, is an excellent method to put into practice. It enables, at the same time, a significant reduction of waste produced globally (packaging, plastic, etc).

If you use a blender you can directly cover with hot water and mix. * Place a clean towel over a second container and filter the resulting coconut milk. press the cloth tightly to obtain as much filtrate as possible. * Place the coconut milk obtained in a plastic bottle and allow to settle until two distinct phases are obtained. We find the coconut cream above and the water below. Drill a small hole in the bottom of the bottle to let the water escape and plug the hole to keep the cream. * Pour the cream into a pan and cook over medium heat, stirring.

The water circulation is only done thanks to a thermodynamic phenomenon called '''[https://en.wikipedia.org/wiki/Thermosiphon thermosiphon]'''. The principle of the thermosiphon system is that cold water has a higher density than hot water because it is more compact. It is therefore heavier and sinking. However, all systems tend towards a state of thermodynamic equilibrium. There is a movement called [https://en.wikipedia.org/wiki/Convective_heat_transfer thermal convection] to mix hot and cold water. For this reason, the solar collector is always mounted underneath the water storage tank, so that the cold water from the tank reaches the collector via a downhill water pipe. When the water in the collector heats up, the hot water rises naturally, pushed up by the cold water and returns to the tank. The cycle tank -> water pipe -> collector heats the water until it reaches an equilibrium temperature. The consumer can then use the hot water from the top of the tank.

  • Ash and animal fat soap  + (A soap is normally composed of a fatty aciA soap is normally composed of a fatty acid (here animal fat) and a basic agent (high pH) such as soda or potash (here made from ash). These two compounds create a saponification reaction that creates soap. The Chemical Process Saponification is the reaction of a fatty substance with hydroxide ions (provided by an alkali such as potash or soda) to give a carboxylate ion (soap) and glycerol (also called glycerin). Soaps are therefore mixtures of carboxylate ions and metal cations (sodium or potassium ions). The carboxylate ion is a surface-active agent that lowers the surface tension of water: it is a detergent. It ensures washing thanks to 4 qualities : The wetting power: soapy water can penetrate the small interstices of the surface in contact (cloth, skin, table, plate...) more effectively than water ; Emulsifying power: the carboxylate ions agglutinate around the dirt and penetrate between it and the surface in contact until they isolate the dirt from this surface. They form micelles containing small particles of dirt. Carboxylate ions have a lipophilic end and are therefore particularly effective against fatty substances; The dispersing power: due to the properties of the carboxylate ions and the structure of the micelles, they repel each other and are therefore dispersed in soapy water; Foaming power: a film of carboxylate ions is formed on the surface of water with low surface tension. By agitating the soapy water, air bubbles can then be trapped. The foam does not intervene as such in the washing but is an indicator of the surface tension of the liquid and thus of its detergent power.he liquid and thus of its detergent power.)

A hole is drilled in the bottle. When you want to activate the fire extinguisher, pierce the bag containing baking soda. Vinegar, mixed with water, reacts with baking soda to form carbon dioxide, water and sodium acetate. By shaking the bottle, the reaction is accelerated: the carbon dioxide produced pressurizes the bottle, and a CO2-water mixture is ejected through the hole, which is pointed towards the fire. Water, carbon dioxide and soda extinguish the fire, and the foam created by the washing-up liquid prevents it from being re-ignited. liquid prevents it from being re-ignited.)

NB 1: the 2 pipes that are used for the (fixed) ash tray and the (removable) feed pipe must have a male fitting at one of their ends to accommodate the stopper. NB 2: A rigorous approach must be adopted when producing the exhaust system, using pipes which are compatible with one another. It is important to avoid leaks (condensates as well as smoke) and also the risk of fire . * Concrete can be made up of sand and fire cement but this will not be as durable as using chamotte concrete/fire cement. Chamotte consists of ground-up fire brick and must contain 25 to 40% alumina. To contact manufacturers of fire bricks, see list in the annex.Grain size of 0 to 10 mm grade is ideal, but 0 to 5 mm can also be used. AVOID making concrete with ordinary cement or ‘black’ cement (unlike fire cement, it does not contain alumina) * Vermiculite: mixed with cement acts to insulate the bottom of the container. You can find this in builder's merchants and garden centres mostly under the names of “Vermex” or “Effiperl” (NB the latter also contains perlite and is a French brand) * Ceramic glass: this is specialist glass which does not expand when exposed to heat and is resistant to thermal shocks of up to 800°C ! You can buy it in the shops (for about €400 to €600 per m²) but you can also salvage it from old inserts, electric hobs, oven doors (inner glass only, otherwise it is likely to have little resistance to heat). Do not use ordinary glass ! To test salvaged glass, stand on a flat surface and put the glass onto a gas camping stove. If it resists the heat, then that is a good sign. The final thing to do for the ‘crash test’ is pour a glass of cold water over it. If there is no reaction, then it is specialist glass. Do not put it on the grass in case it breaks.
