We have the pleasure to communicate you that from 16 to 23 of October Pin Biotranslab, Casa do Río e The Foundry establishes a collaboration to run the event Eco (i) Logic Queer Energy harvesting. The project is possible thanks to the support of GOSH, an network for develop and disseminate projects based on Open Source hardware for Science.

Eco (i) Logic Queer Energy harvesting Italic text The event aims at addressing the lack of women, queer, trans and diversity in technological fields in general and hacking more specifically. But even more so, it aims at creating a community that critically assesses the hegemonic narratives around technologies, the modernity aspects of its underlining Western assumptions and its inherent capitalist inflections, among others. The main purpose of the event is to develop kits that focus on interacting with the natural environment on the field of energy.. the main objective lies on harvesting energy of the natural environment, through wind turbines. These power kits will be scalable and can be used both as pedagogical material and to set up site-specific power plants in different sites as well. There is a counter-infrastructural component to this work: one possible consequence would be to empower people to generate their own energy instead of relying on large and often extractive companies.

Introduction and values of the process

Here starts the documentation of the long process of the prototyping the Hugh Piggott The Piggott Turbine – Wind Empowerment model of an Open source wind turbine. We were changing a bit the goals of the event from developing small kits to going to build the real 2m size wind turbine to provide energy to the rural regional areas we were working on. In that specific event we were working at The Foundry a nice project and association that we have settled on the north part of Galicia into the Northwest of Spain.

During the event many things have been activated between the doers and the visitors; In general It was a wondering experience full of new things to study, learn, doing and understand together.

We chose this model because It was full of layers of interest on the levels of learning, understanding and making it, here some levels mixed up with layers:

first to all is one of the ones that is open source or at least has the option to access the full documentation.

really rich on the pedagogical level, we were really learning through the complete building of the generator itself, about many topics as :

  • electromagnetism
  • mathematics
  • geometry
  • electronics
  • AC-DC
  • welding
  • wood carving
  • sculpting and casting pieces

and much more that was reaching through the nice process of reading, learning and building together.

Process documented by steps

Because of the complexity involved on the realization of the full assembly of the wind turbine we were thinking to divide the documentation in 3 different sections.

Section 1, involves the construction of the devices that will help on the creation of the power generator.

  1.1 wiring coil device 
  1.2 mold to cast the rotor and the Stator of the motor 

Section 2, involves the construction of the alternator parts using the devices we were building on the section 1.

  2.1 coil making (the Stator) using the wiring coil device from section 1 
  2.2 stator casting using the molds from section 1 
  2.3 magnet placements for casting the to layers of the rotor. 

Letś see in detail all the steps needed for the stator :

Step - Generator, stator: Preparation of the cradle.
   Step  - Generator, stator: Preparation threaded stator rods
   Step  - Generator, stator: Preparation of the coil.
   Step  - Generator, stator: Making of 6 coils.
   Step  - Generator, stator: "Star" mounting
   Step  - Generator, stator: Three-phase cable
   Step  - Generator, stator: Making the stator mould
   Step  - Generator, stator: Preparation of the molding.
   Step  - Generator, stator: Molding.

Section 3, involves the creation of the rotor part of the generator:

   Step  - Generator, rotor: Preparation of the metallic disk.
   Step  - Generator, rotor: Preparation of the bell hub.
   Step  - Generator, rotor: Preparation of the template.
   Step  - Generator, rotor: Gluing of magnets
   Step  - Generator, rotor: Preparation of the mold.
   Step  - Generator, rotor: PreStep 1 

Section 4, involves the craving of the blades and the welding of the base for the turbine generator.

  4.1 Making the blades 
   Step 1 - Propeller: The pattern
   Step 2 - Propeller: drawing and cutting of the blades.
   Step 3 - Propeller: Sculpture of the lower surface of the blades
   Step 4 - Propeller: Sculpture of the lower surface of the blades
   Step 5 - Propeller: Blade profile finalization
   Step 6 - Propeller: Construction of assembly supports
   Step 7 - Propeller: Assembly

   4.2 Welding the base to support.
  Step  - Structure, Nacelle
  Step  - Structure, Rudder
  Step  - Assembly, Generator
  Step  - The final assembly and the production test.
  Step  - Balancing of the blades.
  Step  - Lubrication of the wind turbine

"Pedagoxías do vento e das estrelas. As relacións sociais ás que (nunca estabamos destinados a) sobrevivir, tamén vivimos nos nosos corpos dolorosamente, e Audre Lorde non está aquí para lembrarnos esta lección, salvo na medida en que está presente no vento pedagóxico. Pero o vento é o noso mestre (74). -Alexis Pauline Gumbs "

O principal obxectivo deste evento é prototipar un xerador eólico a pequena escala para camiñar xuntos cara á autosuficiencia neste campo. Temos o pracer de comunicarvos que do 16 ao 23 de outubro Biotranslab de Pin e The Foundry establecen unha colaboración para levar a cabo o evento Eco (i) Logic Queer Energy harvesting. O proxecto é posible grazas ao apoio de GOSH, unha rede para desenvolver e difundir proxectos baseados en hardware de código aberto para a ciencia.

EcoLoxicas Queer para a captación de enerxía eolica. O evento ten como obxectivo abordar a falta de mulleres, queer, trans e diversidade nos ámbitos tecnolóxicos en xeral e do hacking máis concretamente. Pero aínda máis, pretende crear unha comunidade que avalía criticamente as narrativas hexemónicas arredor das tecnoloxías, os aspectos de modernidade dos seus supostos occidentais subliñados e as súas inflexións capitalistas inherentes, entre outros. O obxectivo principal do evento é desenvolver kits que se centren na interacción co medio natural no ámbito da enerxía.. o obxectivo principal pasa pola captación de enerxía do medio natural, a través dos aeroxeradores. Estes kits de enerxía serán escalables e poderán utilizarse tanto como material pedagóxico como para instalar centrais eléctricas específicas do sitio en diferentes sitios tamén. Este traballo ten un compoñente contrainfraestrutural: unha posible consecuencia sería capacitar ás persoas para xerar a súa propia enerxía en lugar de depender de grandes empresas e moitas veces extractivas.
