Disrupting the Standard Education System: Green School
John and Cynthia Hardy are not your average people, they are life-long entrepreneurs, and they did not want to provide their children with an average education. That is why, after homeschooling their children for many years, in 2006, they created Green School. Green School emerged from the idea that they wanted to create an educational environment where they felt comfortable sending their own daughters, and one that they believed in.
Since then, they have built a revolutionary model of education, one that integrates sustainability, entrepreneurship all while learning about community and our environment. They began at Green School Bali and have since opened their doors to children and parents in New Zealand, South Africa, and Tulum.
These are some of the core values of the Green school; first, it must be relationship-centered. This means that community is important to this environment of learning. Secondly, it must be experiential, their unique framework of teaching and learning has to be readapted based on the needs of the community they are constantly building. Thirdly, authenticity is a priority, Green school strives to build a programme based on an interconnected network of systems, where sustainability and diversity are at the center of everything. Lastly, it wants to act locally, as an educational organization, they desire to respect the culture, community, and environment they are in, and then think globally.
Green school is a disruptor, and wants people to ask themselves is our standard educational system shaping the future generations in the right way? According to Green School, the answer is clear: we need to start placing our values in culture, environment, and community in order to build a sustainable future.

SOUJI: una nueva vida para el aceite usado
Cada día más y más personas están tomando conciencia del impacto de sus acciones en el medio ambiente. Actualmente, medidas como separar la basura, reciclar, comer menos carne o dejar de consumir plásticos son cada vez más generalizadas y predominantes. Pero un problema gigante que tenemos que abordar es el manejo del aceite de cocina usado.
El aceite vegetal tiene un uso generalizado a nivel doméstico, comercial e industrial. Solamente en el 2019-2020 se produjeron 205,74 millones de toneladas métricas de los principales aceites vegetales, pero solamente el 2.5% se reciclan o son desechadas correctamente. Un factor muy preocupante de estas cifras es que tan solo 1 litro de aceite puede contaminar 1,000 litros de agua.
En España, se estima que dos tercios del aceite usado acaba en las alcantarillas. Esto ocasiona problemas como atascos en las tuberías, necesidad de trabajos especiales en plantas de tratamiento de aguas residuales o aumento de plagas urbanas. La raíz de este problema se podría atribuir al desconocimiento o falta de conciencia acerca de este tema, ya que las principales campañas en pro del medio ambiente no abordan tanto esta cuestión.
Es por esto que al creador de SOUJI, Sergio Fernández, se le ocurrió la idea de este producto. Cada vez que Fernández se disponía a echar el aceite usado por el fregadero, sabía que era una práctica muy perjudicial para el medio ambiente por la contaminación marítima que produce. El problema es que reciclar el aceite usado en España no es tan conveniente. Hay que colocar el aceite usado en botellas de plástico y llevarlas hasta el Ayuntamiento, en donde la municipalidad se encarga de reciclarlo para convertirlo en biocombustibles. Por esta razón, Fernández ideó un nuevo sistema, más conveniente y sin salir de casa: SOUJI.
Y entonces, ¿qué es SOUJI? Es un compuesto que, mezclado con aceite usado, se convierte en jabón líquido para usar como detergente para ropa, limpia pisos o para el lavavajillas. El proceso es muy sencillo: se filtra el aceite usado y se mezcla en las proporciones que se indican con SOUJI. Después de agitarlo fuertemente por un minuto, se produce un detergente listo para ser utilizado, 96% menos contaminante que los detergentes comunes, sin ingredientes tóxicos y muy biodegradable para el medio marino. Además, sus envases están pensados para producir el menor impacto posible en el medio ambiente.
El proceso funciona basándose en la elaboración de jabón convencional. Este proceso, llamado saponificación, une un cuerpo graso a una base y agua, y da como resultado jabón y glicerina. En los procesos convencionales, se usa un ingrediente muy corrosivo llamado sosa cáustica para la elaboración de los jabones y detergentes. La innovación de SOUJI es que no se necesita de sosa cáustica para el proceso de saponificación, cosa que asegura su manipulación fácil y no tóxica.
Doping powers new thermoelectric material
In the production of power, nearly two-thirds of energy input from fossil fuels is lost as waste heat. Industry is hungry for materials that can convert this heat to useful electricity, but a good thermoelectric material is hard to find.
Increasing the efficiency of thermoelectric materials is essential if they are to be used commercially. Northwestern Univ. researchers now report that doping tin selenide with sodium boosts its performance as a thermoelectric material, pushing it toward usefulness. The doped material produces a significantly greater amount of electricity than the undoped material, given the same amount of heat input.
Details of the sodium-doped tin selenide—the most efficient thermoelectric material to date at producing electricity from waste heat—were published in Science.
