The “ArborLoo” The “ArborLoo” Leave the contents -move the loo A method for recycling human waste (Volume II) Peter Morgan Harare, 2000 Introduction The arborloo is a simple pit latrine built over a shallow pit. The concept of the arborloo is being promoted and tested in countries like Kenya, Mozambique, Malawi, South Africa as well as Zimbabwe, where it is thought to have considerable practical application.
This manual records the latest developments in this simple technology, which attempts to recycle human excreta in the simplest possible way. Thus the process whereby human excreta is converted to humus is better undertaken in shallow pits which are moist but certainly not flooded. Also the slab can act as a rainwater harvester if the structure is not fitted with a roof and this again will tend to flood the pit during times of heavy rain. Normally small shallow pits between 0.75m and 1m deep will fill up in family situations in about one year, but there is much variation.

Brandon martella: Live Share Grow. Food as a resource is limited. Supply will soon not meet demand. With population growth, food production in the United States is reaching maximum capacity. Current trends in development create a struggle between farming and living. These two practices are modeled for their own benefit and are soon to clash in a disastrous agglomeration. According to the FDA, the average American alone consumes 707.7lbs of fruits and vegetables each year. With the majority of produce coming from the Imperial Valley, Central California Valley, neighboring states and other countries the 30,000 plus residents of San Diego’s central urban context consume 21,231,000 pounds of produce each year. Utilizing vertical farming, a new model of living can be tested and resolved in a dense vertical community.
The farm tower located in a vertical community of tourist resources and developer condos will provide fresh produce daily to celebrate a direct injection of goods from farm to market. Four African Girls Create Urine-Powered Generator. 7 November '12, 04:58pm Follow What have you built lately? 14-year-olds Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin, and 15-year-old Bello Eniola have created a urine powered generator. All over Africa, young men and women have missioned across the country and arrived in Lagos, Nigeria. These four girls may not end up doing that either, but their efforts definitely stand more of a chance than yet another hyper local social cloud app. Here’s how it works: Urine is put into an electrolytic cell, which cracks the urea into nitrogen, water, and hydrogen.The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder.The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas.This purified hydrogen gas is pushed into the generator.1 Liter of urine gives you 6 hours of electricity.

Leviathan™ Technology « Floating Island International. Floating Island International offers a variety of products incorporating patented BioHaven® technology, none more powerful than the Leviathan. Leviathan uses integrates high-volume, low-head circulation with matrix surface area for maximum wetland performance. Its efficient air-driven directional diffuser draws in and aerates in excess of ten thousand gallons of water per minute, pushing it through the BioHaven matrix and plant roots. A key innovation is the floating streambed, which contributes to the aeration and nutrient uptake.
In a standard Leviathan configuration, nutrients and contaminants are exposed to over 1,000,000 square feet of sticky, biofilm-laden surface area; however, Leviathan is scalable. In fact, those now being designed are large enough to circulate up to 10,000 gallons of water every minute. Leviathan™ Treatment Wetland, Shepherd, MT. Martin Ecosystems. Floating Island Environmental Solutions. Ex-Or. Huge Electricity Savings LED Lighting Solution for Housing Association | Original CAD. Original CAD Solutions is pleased to play a part in a solution offered by CJS Electrical and Ex-Or which is helping Wales & West Housing Association to meet its environmental commitments and stem the rise in maintenance costs.
Lighting loads in communal areas of residential apartments of have been reduced by 80% following the replacement of lighting with LED fittings. In addition, controls avoiding lighting being on 24 hours a day have reduced on times by about 80%. In a typical 2-storey development of 40 apartments, £3000 a year has been cut from the electricity bill which is huge considering that the housing association is landlord to 25 000 residents in 110 housing developments across Wales. CJS Electrical Ltd of Cardiff and Ex-Or, which specialises in lighting control, are working together to provide new lighting systems in communal areas, which include corridors, reception areas and lift lobbies.

Sure Chill® technology | True Energy. Inspired by nature to work with nature, the technology behind Sure Chill makes the impossible, possible A cool problem From refrigerators that chill cans of cola in a hot Manhattan summer to those that store medicines and support blood banks in remote medical centres, refrigeration systems are essential to every part of people’s lives. But they’re inefficient. They need to have constant connection to power and, even in the best conditions, do not control temperature well.
But more than that, conventional coolers are in a constant battle with nature. A simple idea We started with water. An ingenious solution Sure Chill is a brand new kind of cooling system. Water surrounds a Sure Chill refrigeration compartment. A better future Sure Chill is a cooling system that’s life-changing. What scientists say about Sure Chill. Creative thinking : powerful solutions | True Energy. Off the grid street lighting: coming soon to a street near you. It provides light where there is darkness, it gives a sense of safety and security, but it's also a power leech.
The humble street light. Thankfully, the move away from the grid is already well underway with companies like Urban Green Energy busy transforming these familiar towers of light into self sufficient beacons that harness the power of the elements - in this case, both the wind and the sun. Using energy from the sun to power low energy lighting is nothing new of course. There are numerous solar-powered street lighting solutions available, such as offerings from Sharp, Solar Lighting, Solar Street Lights and Bright Light Solar. Urban Green Energy is hoping its solution will stand out from the competition by providing a solar/wind turbine hybrid system that is not just off-grid but looks good too.
Component approach Urban Green Energy's solution also differs in that project designs can be customized to fit client requirements. Getting some attention. Да будет свет... Да будет свет... На выставке стартапов Maker Faire Africa 2012, состоявшемся в г. Лагос (Нигерия), было представлено необычное изобретение: электрогенератор, работающий на моче! Его авторы – четыре африканских подростка: три 14-летних и 15-летняя девочки. Система функционирует следующим образом. В электролитной батарее моча расщепляется на воду, азот и водород. ----------------------<cut>---------------------- Водород отделяется и пропускается через водяной фильтр в газовый баллон, где с помощью буры окончательно обезвоживается.
Молекула мочевины содержит четыре атома водорода, которые соединены с остальными атомами более слабыми связями. Eliodomestico - how it works : gabriele diamanti | designer.
