Solar Cooker Immersion Heater Our project is to build an insulated solar electric cooker to address the health and environmental issues due to biomass cooking in Nepal. With simple and affordable materials, we can apply an appropriate technology providing a solution and an innovation for the Nepali community. More than eighty percent of domestic energy of Nepal comes from biomass such as wood, cattle manure, and agricultural waste. Our solution is to build a solar electric cooker and an immersion heater to address these issues. We are partnering with Tashi Ghale, a Nepali student with a direct connection to the people in Nepal.

Thermal Storage Cooking Insulated Solar Electric Cooking Research. Our target community is Malawi, our particular innovation is thermal storage capacity and phase change materials, though we may be interested in pursuing something slightly different (think sous vide technology– but cheap). Monday Shop

ISEC Malawi Our group is building on an Insulated Solar Electric Cooker so that it can get hot enough to fry foods. Our target community is Malawi in Africa! We are in contact with Kuyere!, a solar product provider that is already on the ground in Malawi. Check out our website to see updates on the design and use of our cooker.

ISEC in Ghana Ghanaian cooking is at the centerpiece of Ghanaian traditions and is very important in their everyday lives. Ghanaian main dishes are organized around a starchy staple food such as yams, with which goes a sauce or soup containing a protein source. Along with this is Garri, which is a version of fast food for Ghanaian people that they eat on a daily basis. However, cooking stews and Garri in traditional methods sometimes takes days to prepare. Using our Ghana contact of Nathan Heston, we plan to create an insulated cooker centered around Ghanaian food we plan to create a fast, cheap, and easy way for the people of Ghana to cook Garri along with their favorite stews. For any questions or ideas please contact us (at right) and keep up to date on our website! Tuesday Shop Daniel Cragoe Justin Canterberry Jessica Rouse Chase Braun (
Solar Electric Kitchen Building on our Insulated Solar Electric Cooking Research, our group has a personal challenge to develop an efficient and effective component for a solar kitchen.  Our target community is Quail Springs, an intentional permaculture community an hour inland from Santa Barbara. We are helping the wonderful Jan Smith ( design and build a stove component for their solar cooking kitchen. Tuesday Shop

New Website SolarForTheSoul  SunToSupper SolarForTheSoul We are working to improve the lives of people in Malawi by providing them with an alternative cooking means and method. Traditionally, cooking is done over stoves that burn biomass, and this results in deforestation, carbon emissions, and exposure to smoke that can cause health conditions such as asthma. Our goal is to create and experiment with solar cooking technology that could at least partially replace the biomass method and result in healthier lifestyles for the people of Malawi and their environment. We will be collaborating with Kuyere and the City University of Seattle on this project. Tuesday Section Troy Knatt Willie Gabriel Ava Maslan ( ) Emma Sullivan, Nick Tuanchaem Garrett Perkins (
Solar Ice Website
Building on the research from Cal Poly’s Summer 2018 direct solar electric ice production, Solid State Solar Ice Project, our group takes on the challenge to make a directly solar-powered thermoelectric cooler (TEC) capable of constant ice production (Solar Ice) for use in rural Ghana. This project is currently under research by Cal Poly Physic students Casey Smith and Nathan Heston, who have worked closely with: Solar Ice Production and The Social Ice Cream Co.’s Solar Ice Cream Truck. We plan to assist their research in testing TEC design via the use of Peltier modules and to preform research on phase change materials to fill the freezer with to aid in efficient heat transfer for ice production.
Our mission is to build a sustainable, ethical, and low maintenance device that will improve the lives of many people.

New SSF website Slow Sand Filter in Ghana There is a need for clean, filtered water in Ghana. To solve this problem, we have made efforts to create a slow sand filter to be implemented in Ghana. A Slow Sand Filter has been used to prevent the spread of disease for over 150 years. Although these systems are slow, they are cost-effective and, thus, sustainable for low income countries. The system is set up so that the top layer of sand physically filters the water as well as biologically treats it through the use of biological organisms to remove pathogens. This complex biological layer is called Schmutzdecke. Monday Shop Haley Griffiths Hannah Randolph Kevin Masukawa Bailey Yuen (
Black Soldier Fly Larva Breeding Postpartum Hemorrhage is the leading cause of maternal mortality in the world due to insufficient blood clot by the mother leading to fatal blood loss. Current methods used to determine if the mothers blood will clot or not are both unclear and time inefficient leading to a higher mortality rate. If there was a device that could determine if a patients blood will clot both accurately and timely, the death rate for women in labor would be drastically decreased. Luckily there is. Cal Poly Biomedical graduate student Sara Della Ripa, has developed a device that diagnoses if the blood will clot within two minutes of testing and is very accurate. Working with her this quarter, we want to help her refine her design to make it the most affordable and sustainable device on the market., please also see last year’s project: Blood Clot Diagnostic Website.

Food Preservation We are working to identify a sustainable solution that will effectively store food against pest and rodent intervention and relative humidity as high as 90%. By achieving this, we can reduce aflatoxin (mold) contamination post harvest. Spring 2017, a group worked on a Flour Container with Peggy C. Papathakis (Food Science and Nutrition, Cal Poly). Feedback from both Peggy and Mark Manary (the Peanut Butter Project) indicated that this is a good direction. Spring 2018, a group determined that high end, ultra low humidity storage is cost prohibitive: Food Storage. However, our summer research indicates that this high-tech, expensive technology is wholly unnecessary. Monday Shop

New Website Meal Worms Meal Worms for Meals Our Group is faced with the task to build a habitat and raise insects for consumption. Insects are a good source of protein and have a very small environmental footprint compared to larger animals such as cows for the production of beef. Through research and the help of last fall’s project “Insects for a Sustainable Future”, we have decided that mealworms are the most cost effective and simplest insect to raise for consumption. We will start to raise mealworms in our homes, then discover different methods of cooking and preparing the insects for human consumption. Tessa Grano Miche Naziri George Hamalian Dean Garrido (
Uganda Solar Water Heater Our group will be building a solar water heater for the community in Uganda. Currently, one community spends on average $600 a month heating up water to cook (beans? Or rice i forget). With a simple mechanism that costs less than $50, we will be heating up water using the sun’s energy to allow the community to start their cooking day with preheated water. Although it’s hard to get it to boiling using the materials we will be using, this community can start their day with water preheated to about 60 degrees celsius, saving them hundreds per month on water heating.
