ReDesigning Eros - Love All Beings 1a
- 1. Energy & EcoTechnology Module 4 of the PDC+++PDC + + + We dedicate this Module to the Mother & Father of Integral Permaculture: Dana Meadows & Howard Odum, two original pioneers who helped humanity make great strides in understanding systemic thinking, in all four quadrants. How do we Design good EcoTechnologies? Part 1 * Technology is the application of science, so a good basic knowledge of science is essential if we are to design technologies of any kind. * And everything that transforms energy or matter from one form to another is a technology, so science and technology really are basic for life, and certainly for designers. * In this first part of two we explore the relevance of space elevators to permaculture, then delve into the science of heat, flows, optics & materials in order to understand how to best design ovens, solar devices, heating & cooling technologies - with lots of examples Class M4.9 EcoTech

"Love (erôs) is the oldest of all the gods." images from "Big History" TED Talk by David Christian "Firstly, ancient Khaos’s stern Ananke (Inevitability), and Khronos (Time), who bred within his boundless coils Aither (Light) and two-sexed, two- faced, glorious Eros [Phanes], ever-born Nyx’s (Night’s) father, whom latter men call Phanes, for he first was manifested."

- 38. Lighting See "Biological Rhythms" in www.bit.ly/EcoTechnology The pituitary gland is called the master gland because it directs the actions of the endocrine glands that are below it. Clinically, each endocrine organ has a very specific nutrient that makes it work. Unbelievably, the specific nutrient for the pineal gland is light. In order to function normally, the pineal needs to be exposed to the entire spectrum of light. It is interesting to note that the pineal gland is the remnant of a third eye that appears early in the developing fetus. Mystics have been saying for centuries that the third eye is responsible for our inner sight (insight), and directly connects us to our spiritual self.

Notes de l'éditeur
- Module 4. Despite the fact that many &apos;Technological Improvements&apos; haven&apos;t managed to improve the quality of life for the majority of people, but have brought more problems & pollution, we still keep expecting the arrival of a more modern technology, perhaps more ecological, that will restore & reverse the damage made. In fact, it is possible, but not without having more citizens with a better understanding & a wider vision of what technology is, & who also understand some basic science necessary in order to be able to think for ourselves on these subjects.

- Schumacher was one of the first economists to question the appropriateness of using gross national product to measure human well being China also implemented policies similar to appropriate technology during the reign of Mao Zedong and the following Cultural Revolution. During the Cultural Revolution, development policies based on the idea of &quot;walking on two legs&quot; advocated the development of both large-scale factories and small-scale village industries.

- Thermodynamics Explains It All frm http://www.ridgenet.net/~do_while/sage/v7i1f.htm Everything happens because heat is flowing from a hot place to a cold place. Nothing happens without heat flow. There are no exceptions. That’s why thermodynamics, which is generally a mechanical engineering course, is usually required for graduation with a mechanical, electrical, civil, or chemical engineering degree. Furthermore, thermodynamics is an exact science. If one can do the math, it is possible to calculate the maximum amount of work that can be done, or the actual efficiency of any machine, entirely from an analysis of temperature differences and heat flow. So, if a machine needs to do more work than can be done by the heat flow associated with it, that machine cannot possibly be built. Thermodynamics is, from an engineer’s point of view, the ultimate science. It explains the operation of the entire natural universe. That is what makes the study of thermodynamics so interesting, exciting, and relevant. So, with that introduction, let’s start to investigate thermodynamics.

- La chimenea negra se calienta al sol Se calienta la estructura, y con ella el aire en su interior El aire sube, saliendo por arriba y entrando por abajo Distintos diseños de la estructura (diferente inclinación, longitud, color, superficie de recolección de calor, superficie de entrada y salida…) producen distintos flujos de aire y distintas diferencias de temperatura y de presión (especialmente importante para turbinas de producción de electricidad). Las chimeneas solares pueden ser muy simples o muy complejas. Pueden También pueden tener sistemas de colección debajo del flujo, usando cristal para la estructura de la chimenea. Además de servir para mover aire y enfriar, las chimeneas solares también pueden usarse para calentar de forma similar a cómo funcionan los muros Trombe.
- El fondo negro atrapa calor, y el cristal no lo deja escapar Se calienta la estructura, y con ella el aire en su interior El aire sube, saliendo por arriba y entrando por abajo Aumenta la eficiencia si es perpendicular a los rayos solares. Pueden colocarse más cosas dentro (ej: tuberías de latas) El aire las toca, se frena y se calienta más(se puede crear turbulencias en el flujo de aire, modificando las uniones de las latas, para aumentar este efecto). El aire que entra acaba saliendo muy caliente(pero fluye más despacio)
- La luz solar pasa por un cristal y calienta un muro Por el día circula aire frío de la casa que se calienta entre el cristal y el muro Por la noche el muro irradia hacia dentro el calor del día.
- El agua pasa por conductos (tuberías, mangueras…) pintados de negro, calentándose con la luz del sol. Normalmente, el agua entra por debajo y sale por arriba (sube naturalmente al calentarse). Aumenta la eficiencia si es perpendicular a los rayos solares. Puede aumentarse la eficiencia si se cubren los conductos con un material que provoque efecto invernadero (cristal, metacrilato, botellas de PET…). Cuidado con los materiales escogidos, ya que la estructura puede no soportar las altas temperaturas y/o presiones, y el uso que se va a dar al agua, ya que el agua calentada suele no ser potable (especialmente si los conductos son de plástico).
