Sorin Grama of Promethean Power Systems discusses their refrigeration solution that uses a thermal energy battery pack that charges on solar power and/or a few hours of grid electricity. This allows remote dairy farmers to reduce the time that milk is unchilled by 75 percent.
Brian Jensen of SunDanzer discusses their portable solar chest refrigerator that utilizes photovoltaic power to freeze phase-change material, keeping collected milk cold in sterilized aluminum milk containers until Kenyan dairy farmers transport their product to processing facilities.
William Kisaalita of the University of Georgia Research Foundation discusses their refrigeration unit powered on biogas extracted from cow manure. Reusable zeolite plates capture water vapor from the evaporative milk chilling process.
Motivo is a product engineering firm that focuses on complex engineering projects—from cars that can power micro-grids to consumer electronics and everything in between. Enjoy this behind-the-scenes peek and catch a glimpse of a few of their exciting projects.
“Our innovative milk chilling system, which reduces milk spoilage in rural India, would not have been possible without the Planet NI program. Through the program, NI saw the opportunity to help with a project which has significant social and environmental impact and they worked with us to make their products accessible.”
After winning 2nd place at MIT’s business plan competition, Promethean’s partners went to rural India to explore untapped opportunities when one cold-call to a large dairy in Bangalore focused them on developing a solution to chill milk without diesel power generators.
Promethean Power Systems envisions developing a milk-chilling system for use in rural off-grid and partially electrified areas of developing countries utilizing a thermal energy battery, making the system economically viable in parts of the world where the power grid is unreliable.
