CCAT natural paint project
CCAT natural paint project. The Campus Center for Appropriate Technology (CCAT) at Humboldt State University in Arcata, CaliforniaW is completely remodeling the inside of their building. When all of the construction is finished the entire interior of the house will need to be painted. As an ENGR 305 project, Spring 2007, Andrea Lanctot and Jill Anderson have decided to make all the interior paints from scratch using safe natural ingredients.

The project has four main goals. The first is to research natural paint ingredients, recipes, and techniques. The second is to make several of the recipes and test the paints for color, durability, and texture. The third is to choose paints from the tests for the new CCAT house and apply them to the interior. The last goal is to test the final application with the test of time. See natural paint basics for background research on ingredients, types and advantages/disadvantages of natural paint.

Cathy Leslie, Executive Director of Engineers Without Borders-USA
In order to stay competitive, tomorrow's engineer will need to become more culturally savvy, as well as adept at implementing appropriate technologies. Capacity building is not about constructing a showcase engineering project. It's about coming up with practical, sustainable solutions that fit the environment, its people and the culture as well. (ASME)

In physics, energy is an indirectly observed quantity. It is often understood as the ability a physical system has to do work on other physical systems. Since work is defined as a force acting through a distance (a length of space), energy is always equivalent to the ability to exert pulls or pushes against the basic forces of nature, along a path of a certain length.

Sustainable energy is the provision of energy that meets the needs of the present without compromising the ability of future generations to meet their needs. Sustainable energy sources are most often regarded as including all renewable energy sources, such as hydroelectricity, solar energy and power, wind power, wave power, geothermal energy and power, biomass fuel and energy, and tidal power. It usually also includes technologies that improve energy efficiency.

While many renewable energy projects are large-scale, renewable technologies are also suited to rural and remote areas, where energy is often crucial in human development. As of 2011, small solar photovoltaic (PV) systems provide electricity to a few million households, and micro-hydro configured into mini-grids serves many more. Over 44 million households use biogas made in household-scale digesters for lighting and/or cooking, and more than 166 million households rely on a new generation of more-efficient biomass cookstoves.

ENGR 215 Introduction to Design projects – Fall 2008: Full Belly Project: The Fall 2008 semester of Engineering 215 worked with the Full Belly Project to adapt their Universal Nut Sheller in the following three manners:

Fall 2008 ENGR 215 Intro to Design Projects - Full Belly Project
The LC sheller
Innovating concrete with sawdust and clay to lower the costs and weight using materials available in some parts of Western Africa  
The Full Bell
Improves the original UNS by reducing the cost and increasing durability of the sheller  
Hot Dang Plastic Encasement
Waste plastic bags available in Haiti cleaned, cut, crocheted and ironed into a hard plastic mold  
Pressed Plastic
A process to thermoform waste plastic bags to form molds for nut shellers using resources available in Haiti  
Nutsy
Shaped like an acorn the Nutsy aims to be a smaller, more portable, and more aesthetically pleasing version of the UNS for marketing within the US  
Multiplicity
Smaller U.S. prototype with exchangeable rotors for different size nuts  
Simple Simon
