This document describes a mobile IT cafe and rural broadband unit that provides sustainable design solutions and advice to rural communities. It aims to help communities access open source solutions via broadband and show examples from other eco-villages of living sustainably without bills through renewable energy and communal sharing. The service is offered via a mobile gazebo or vehicle and helps address issues of rural poverty and isolation.
Eco village culture to and industrial economy city culture r1
The document compares life in an industrial economy city to an eco-village. In an industrial economy city, people live in large buildings built by others far away using materials shipped in. Food comes from large, processed corporations. Interactions are limited and decisions are made by distant elites. In an eco-village, people build their own homes and community together from local materials. Food is produced and consumed locally and seasonally. Everyone knows each other and makes decisions collectively. Work follows natural rhythms rather than constant activity.
Waste management
The document discusses waste management at Govardhan Eco Village, a farm community located 110km from Mumbai. It describes how the integrated waste management system recycles both organic and inorganic waste. Organic waste from food, humans, animals and foliage is converted into compost, biogas or mulch. Inorganic waste such as plastics, construction materials and packaging is reused for agriculture, energy or products. The eco village aims to present a sustainable living model through community living and education in traditional sciences.
Transformation of traditional village into eco-village
We have defined eco-village as a rural human settlement with all members committed to sustainably manage locally available natural resources with integrated comprehensive human right based approach to meet their social, spiritual, psychological, physical (including technological) and economic needs without any negative impact on natural ecosystems, resources, climate and health. Ecovillage thus addresses the social, spiritual or cultural, ecological and techno-economic discrepancies and instabilities through sustainable community based structures, practices and concepts from holistic right based perspectives.
Ecovillage has social, physical, spiritual or cultural and ecological (including techno-economic) structures or systems. Each system has subsystems that interact with each other.

Build It Green
An eco village is designed to be environmentally sustainable and promote community. It aims to integrate human activity and development harmlessly with nature at a human scale. Key aspects include allowing nature to inform the village layout, using local and natural materials, growing food on site, sharing communal spaces, and finding economic sustainability without harming the environment or future generations.
Eco village presentation
Ecovillages are communities that strive to integrate a supportive social environment with sustainable living through practices like permaculture, ecological building, renewable energy, and community building. A day in an ecovillage would show a green and pure rural or urban area unlike a normal town, where all aspects focus on being environmentally friendly. Spending a week in an ecovillage could provide an interesting and healthy experience, especially for city dwellers, by allowing them to learn about and immerse themselves in nature.
Govardhan eco village
Govardhan Eco Village (GEV) is an attempt to highlight the importance of living in harmony with nature through sustainable construction practices. To comply with green building norms, GEV preserved the landscape during construction, optimized energy and water usage, and sourced over 90% of materials locally to reduce carbon footprint. GEV also utilized natural insulation and a green sewage system called Soil Biotechnology that recovers 95% of water for reuse while integrating with natural cycles. Construction waste was reused to create permanent raised beds for rice and vegetable cultivation.

This document summarizes research on using ultraviolet (UV) light to inactivate Escherichia coli (E. coli) bacteria in water. The research tested water samples from three locations in Ambazari Lake in India over different seasons. Testing measured physio-chemical parameters like turbidity, pH, and hardness, as well as E. coli levels before and after UV treatment. Results found physio-chemical parameters within standards, and over 99.999% reduction in E. coli after UV exposure times from 0.5 to 8 hours depending on initial bacterial levels and water quality. The research concluded UV light is an effective alternative to chlorine for water disinfection, avoiding harmful chlorination byproducts, though pre-
Modelling the Kinetic of UV Water Disinfection
This document summarizes a study that models the kinetic of UV water disinfection. Two kinetic models, Chick-Watson and Hom, were tested on their ability to model the disinfection of E. coli and L. Helveticus bacteria under UV light alone, UV with TiO2 photocatalyst, and UV with ZnO photocatalyst. Both models fitted the experimental data for disinfection of E. coli but neither model fitted the data for disinfection of L. Helveticus, showing the limitations of empirical models in representing all microorganisms. The document concludes the parameters in empirical models have no physical meaning and the models cannot be generalized to all cases of microbial disinfection.

This document evaluates the use of ultraviolet (UV) radiation and ozone for disinfecting primary municipal wastewater effluents. Experiments tested different ozone concentrations and UV fluencies at varying pH levels. Ozone doses near 20 mg/min achieved 72-78% removal of fecal and total coliforms, and removed up to 36% of chemical oxygen demand (COD). UV achieved over 80% inactivation of bacteria. Both treatments were most effective against bacteria at pH levels other than 7. UV treatment had lower energy requirements than ozone treatment. The study demonstrates the potential for UV and ozone processes to generate safely reusable or releasable effluents from primary wastewater treatment.Engeenuity presentation 2012 feb
The Engeenuity process uses a combination of naturally occurring light, magnetic fields, temperature and other natural elements to inhibit pathogen growth in food and water. It does so in a way that is non-chemical, non-toxic, and requires no artificial power source. Studies have shown it can maintain microbial levels in cooling towers, extend the shelf-life of bread by 11 days, and accelerate sedimentation in wastewater treatment by 30%. The process works by disrupting pathogen electromagnetic waves without harming healthy organisms, through various proposed mechanisms such as impacting protein ions, calcium ions, or DNA. It has demonstrated effectiveness in independent lab tests controlling E. coli in water for over 4 days and keeping milk microbiologically safe

The Engeenuity process uses a combination of naturally occurring light, magnetic fields, temperature and other natural elements to inhibit pathogen growth in food and water. It does so in a way that is non-chemical, non-toxic, and requires no artificial power source. Laboratory and industry tests have shown the process extends the shelf-life of bread by 11 days and keeps microbial levels in cooling tower water and milk below acceptable levels for over 46 and 93 days, respectively, after expiration dates. The process is believed to work by disrupting the electromagnetic signals of pathogens using specific magnetic field frequencies, without harming healthy organisms.

This document studied the effects of water quality factors like turbidity, total organic carbon (TOC), and salinity on the inactivation and repair of two microalgae - Microcystis viridis and Tetraselmis suecica - following medium-pressure UV irradiation. It found that increased turbidity, TOC and salinity levels generally reduced UV disinfection efficiency for both microalgae. TOC in particular promoted higher levels of photoreactivation and dark repair for M. viridis. T. suecica showed more sensitive responses to changes in the three water quality factors than M. viridis.

The turbine would use a spiral axis design based on an existing model, with magnetic levitation to eliminate bearings. It would include solar panels, batteries, inverters, converters and controls. Performance is analyzed for Huntsville, AL wind speeds which average around 15 mph and are sufficient to operate a small turbine. The project is broken into phases with milestones to complete design, testing, and implementation.

- 1. The Eco Lilly: Autonomous Ultra Violet Swimming Pool Cleaning System Jürgen Sawatzki Chaw, Professor Dennis Hite Department of Electrical and Computer Engineering Overview Key Findings Impact on Society Explanation Acknowledgements The purpose of this research was to create an intuitive and easy-to-use solar-powered system with: autonomous functionality, portability, sustainability, and ecological friendly capabilities swimming pool cleaning system (based on UV light generation); in order to disinfect harmful bacteria and to reduce chlorine levels. This prototype reduces bacteria levels between a Log1 (90%) and a Log5 (99.999%) efficiency on the first pass. Results were based on Pseudomonas Aeruginosa and Shigella Flexneri, known to cause “Swimmer’s Ear” and Upper respiratory infections. Adults, children and people who suffer from skin diseases will be able to enjoy recreational bathing in swimming pools without experiencing any adverse reactions to toxic cleaning chemicals and bacteria. This device will help people become more ecologically friendly by reducing their energy bill, as it does not rely on grid power, but rather on solar power. 15th Annual University of Alabama System Honors Research Day - April 19, 2016 Tennessee Valley Authority, Faculty Advisor: Prof. Dennis Hite, Dr. Azucena Chaw, Eng.
