Global Innovation Seminar Series: Nicole Weise + Nathan Schrag
Please join us to learn about the adventurous, hilarious, and technical story of the first solely mechanical EWB project in Guatemala. Through this project’s failures, successes, and development, mechanical engineering seniors, Nicole Weise and Ethan Schrag, have been working with Guatemalan farmers, in coordination with Heifer International, to improve the fuel efficiency of cardamom spice dryers. Since deforestation is a growing concern and wood is becoming more expensive, the net profit for Guatemalan farmers is decreasing with the increasing operation price of a cardamom spice dryer. To promote environmentally sustainable drying processes and reduce wood consumption for the dryers, the MSOE-EWB team has created a simple solution to improve the thermal efficiency using an attachment called “swirlers.” The swirlers are economically feasible and effective, costing less than $2 per dryer while increasing fuel efficiency by up to 20%.
