En este tutorial, veremos cómo hacer un sencillo filtro de arena para obtener agua filtrada. Este filtro de arena es muy similar a los filtros de agua que podemos encontrar en comercios y tiendas especializadas en tratamiento de agua.
This handmade kit creates a personal experience of participating in a productive food cycle. Human urine, the natural product of our bodies’ daily metabolism, is a sterile solution rich in excess nutrients. The kit lets you recycle the excess nutrients your body creates when you eat and drink into more life, locally. You can take this kit home, pee in it, and perform a biochemical reaction that transforms the nutrients in your urine into an immediately usable fertilizer to feed your own plants.
My guide is different. I explain exactly what a kilowatt hour is and how much you pay for one. And I show you how to calculate exactly how much electricity your household appliances use, so you know which items are guzzling the most juice (and which ones are the best targets for savings). You'll also learn exactly how to read your electric meter, if you like. (Find that on any other website.) And I not only give you meaningful tips for slashing your electricity consumption, I give you the tools to figure out exactly how much you're saving as well. Finally, I've answered countless questions from readers about saving electricity. If you have a question, it's probably answered here already.
In the Air is a visualization project which aims to make visible the microscopic and invisible agents of Madrid´s air (gases, particles, pollen, diseases, etc), to see how they perform, react and interact with the rest of the city. The visualization tool is a web-based dynamic model which builds up the space the components generate, where through data crossing behavior patterns emerge. The results of these data feed a physical prototype of what we have called a “diffuse façade”, a massive indicator of the air´s components through a changing cloud, blurring architecture with the atmosphere it has invaded and mediating the activity of the participants it envelops.
Soil Kitchen is a temporary, windmill-powered architectural intervention and multi-use space where citizens enjoy free soup in exchange for soil samples from their neighborhood. Soil Kitchen offered free pH and heavy metal testing and produced a Philadelphia Brownfields Map and Soil Archive. In addition to serving soup and testing soil, the building is a hub for exchange and learning; free workshops including wind turbine construction, urban agriculture, soil remediation, composting, lectures by soil scientists and cooking lessons.
In the world we live in, data drives activism. The dialog online has reached a deafening roar and everyone has a cause, so it takes hard evidence to turn heads. We do not have access to the technology that builds $50,000 air quality sensor systems, but we do have the ability to put 50,000 $100 sensors systems into a city, a collective voice which won't be able to be ignored.
The bio-digester kitchen island is the central hub in the Microbial Home system. It consists of a methane digester which converts bathroom waste solids and vegetable trimmings into methane gas that is used to power a series of functions in the home. The bio-digester hub is designed as a repositionable kitchen island, including a chopping surface with vegetable waste grinder, a gas cooking range, a glass tank that shows energy reserves and glass elements showing pressure, volume and readiness of compost sludge. Materials used in the design are copper, cast iron, glass and bamboo. ‘Bio-gas’ is produced by developing a culture of suitable bacteria living on organic waste material from the home. The gas the bacteria generate is collected and burnt. This arrangement is called a methane digester and it has been used in various configurations for centuries. The gas from the methane digester in the Microbial Home is fed to a cooking range and gas mantle lights. Water pipes are preheated by the digester and channeled to other components in the Microbial Home system. The digester needs a constant supply of waste material and water. The dehydrated sludge residue from the digester can be safely removed and used as compost. via Martin de re:farm

Eliodomestico is a solar household still for the developing countries. Eliodomestico is an open project, free to the people who need it. It intends to bring drinking water from salt water.
FESTIVAL ÜBER LEBENSKUNST http://www.ueber-lebenskunst.org/ Perspecives of a sustainable way of living At first, a big hydroponic salad installation in the pond in front of the Haus der Kulturen der Welt feeds the hungry visitors of the festival. The focus on local production.
Si la sequia o el bolsillo apremian, lo que os presentamos es una técnica de riego por medio de la condensación del agua, dentro de una botella de plástico calentada al sol. Es un método fácil y accesible para cualquiera, y permite utilizar agua de mar, ya que, al evaporarse, condensarse y volver a caer, cualquier mineral que contenga el agua se queda en el recipiente, incluida la sal.
Sarah Sze presents a an elaborate architectural sculpture that allows park visitors to physically enter and pass through the space it outlines, while also attracting birds, butterflies, and insects with perches, feeding spots, and birdbaths.

A vertical hidroponic garden for growing food on your windows. If you've got tools, space, a little extra time, and a knack for building things, constructing your own windowfarm gives you additional control to customize the system for your own setup. You will need to register on the community site and accept community terms of service before accessing the plans.
Ecotopia Biketour will be cycling through southern Europe this year, the project is being hosted by Research and Degrowth. This year’s theme is “towards degrowth” - challenging the growth mentality which currently dominates and overlooks real social and environmental values. We are an eco-mobile do-it-yourself activist community emerging every summer already for 20 years. We aim to learn from each other and local groups we visit, support their campaigns with creative ways. We carry all our equipment on bikes & trailers and make all the group decisions by consensus. A project for everyone interested in being part of a community and travelling without engines – the exact opposite of an all-inclusive flight to the beach!
Typical prices for bulk purchase of fuels at domestic or small commercial scale, February 2012 N.B. These prices are intended for guidance only and represent the typical cost per unit of fuel energy for comparison. This is not the same as cost per unit of delivered heat which will depend on the efficiency of the boiler or stove, and may also include other charges such as service and maintenance for heat supply contracts. All prices are prone to significant variation with geographical region, tariff choice, order quantities, overall contract size and duration, time of year, delivery distance and time, etc. Woodfuels in particular are available at prices both significantly above and below those quoted, and bulk prices will be subject to a minimum delivery size of perhaps 3-5 tonnes. Wood pellets bought in bags may be significantly more expensive than those bought in bulk.

¿ espiga ? Ahora bien, dado que se pueden dar dos tipos de tratamiento y uno de ellos incluye la utilización de bromuro de metilo y siendo como es una sustancia perniciosa para el medio ambiente, aconsejo decantarse por maderas de palets que utilicen el tratamiento térmico para su desinfección. En su parte derecha lleva: MB = fumigación con bromuro de metilo.
The Microbial Home Probe project consists of a domestic ecosystem that challenges conventional design solutions to energy, cleaning, food preservation, lighting and human waste.
La cuenta atrás de un proceso irreversible posiblemente haya comenzado: el final del petróleo y con ello el de un modelo de producción de alimentos. La alternativa se podría llamar Permacultura. Via cusámaco
Got Bee's? I knew this day would come. One day all those bees would make some honey then I would have to make a honey extractor-anator and extract all the honey in the tri-state area. After all what could go wrong? This project went together by solving one problem at a time in sort of a hap hazard way and getting a bit of luck every know and then. Sorry if some of the pictures seem out of order I just went building the parts as i thought of them then wrote this trying to put them in a logical order. The theory behind the extractor is to spin the frames of honey flinging the honey out and leaving the wax intact. I wanted to spend as least money as possible (under the price of a store bought one 150.00+) and to use what I had on hand.
The Soda bottle pasteurizer is a solar water heater and pasteurizer made from everyday recyclables.
Aquaponics is a sustainable food production system that combines a traditional aquaculture (raising aquatic animals such as fish, crayfish or prawns in tanks) with hydroponics (cultivating plants in water) in a symbiotic environment. In the aquaculture, effluents accumulate in the water, increasing toxicity for the fish. This water is led to a hydroponic system where the by-products from the aquaculture are filtered out by the plants as vital nutrients, after which the cleansed water is recirculated back to the animals. The term aquaponics is a portmanteau of the terms aquaculture and hydroponic.
Rainwater Harvester/Greywater System Feedback Loop is a water saving system made from salvaged materials. It stores two types of water–water that normally runs away while becoming hot and rain water. The water is stored in the 3 small recycling bins which can also be used as benches to sit upon. The hand crank device on the right is used to pump stored water back to the sink to be used at a later time. The sink is equip with a variable drain allowing you to decide to let your water run back into the storage units, into the greywater system to the garden or out to the city system.
