Si no hay donde separar vidrios, plásticos y papel, no es raro que poco se piense en que hacer con los remedios vencidos o el aceite usado (Españoles casi no reciclan aceite y medicamentos, escena común en otros países

The Solarflower is an open source solar energy collector which tracks the sun automatically through a simple non-electrical mechanism. It can be made almost anywhere from common recycled and salvaged materials using basic tools and skills, is portable, has no running costs or emissions, and can produce up to kilowatts of power per device. Depending on available resources it should take one to three unskilled people less than a week to build, and cost well under €$£ 100. Potential examples of use could include: Electrical production with simple steam turbine/piston, with waste heat going to oven or hot water system.Dome oven with integrated water system for temperature regulation and hot/pasteurized water.Steam distillation of water for removal of chemical, heavy metal, and biological toxins.Medium to large scale food dehydration, processing, and roasting.Conversion of fibrous organic waste into charcoal for energy storage and low smoke cooking, with coproduction of bio-oil and bio-gas.And any other application utilizing heat.

¿Has considerado aprovechar los residuos de alimentos y de la cocina para producir biogás casero? Si es así, puedes construir un biodigestor anaeróbico casero a partir de un bidón o tanque de polietileno con capacidad entre 120 y 220 litros. No se necesitan grandes conocimientos técnicos ni materiales difíciles de conseguir para su construcción; solo observe la imagen, lea los materiales y lo comprenderá. El diseño propuesto es bastante común, y al ser semi-continuo permite adicionar residuos orgánicos diariamente. Via pez [estudio] Delete the scoop?

Sam Redfield ha diseñado un pequeño generador hidroeléctrico de bajo costo que puede construirse casi completamente a partir de PVC y plástico. Utiliza un alternador de imanes permanentes como generador eléctrico y un balde plástico de 5 galones (19 litros) como cubierta del aparato. Via pez [estudio] Delete the scoop?

Con poco más de 5 dolares, mucho material reciclado y 3 horas de trabajo podemos construir nuestro propio calentador solar de agua. Todavía esta en fase de mejora pero promete mucho. Ahora mismo nos ofrece la posibilidad de calentar pequeñas cantidades de agua a una temperatura decentemente caliente. Via pez [estudio] Delete the scoop?

Un digestor de desechos orgánicos o biodigestor es, en su forma más simple, un contenedor cerrado, hermético e impermeable (llamado reactor), dentro del cual se deposita el material orgánico a fermentar (excrementos de animales y humanos, desechos vegetales-no se incluyen cítricos ya que acidifican-, etcétera) en determinada dilución de agua para que a través de la fermentación anaerobia se produzca gas metano y fertilizantes orgánicos ricos en nitrógeno, fósforo y potasio, y además, se disminuya el potencial contaminante de los excrementos.

About the Presentation This webinar will offer an interdisciplinary perspective on solar innovation in the United States by examining over 100 case studies. It will use these research findings to describe how self-organizing groups, or "tribes," have become a driving force in transforming the solar innovation industry nationally and globally, and also focus on their potential to transform the value network. The webinar will highlight various characteristics of successful tribes. Factors such as dynamics leading to formation, patterns of growth, evolution, and, in some cases, demise will be examined as well. The presentation will also describe the place and relationship of the ideal entity within existing and future solar innovation clusters. The current status of the United States' competitive advantage will be discussed by comparing emerging and established regional solar innovation capabilities. A framework will be offered to provide government and industry decision-makers with an approach that can be implemented immediately to build a global competitive advantage. This research was funded by the US Department of Energy. Via pez [estudio] Delete the scoop?
