EWB-JSC President, 2011-2016

Jacob Cordova

Under Jacob's leadership role, involvement at the Johnson Space Center chapter increased and two regional projects were maintained. The chapter constructed a Bring Your Own Water test and development system, fabricated a portable solar power system cart, invented a fruit slicing device, and organized a post implementation trip to Mugonero, Rwanda. Jacob's concurrent role as Chief Architect for the Engineering Sandbox at NASA (for additional information, reference the related article and video) was also instrumental in ensuring innovative organizations such as EWB would have access to prototyping and development resources, and upon the grand opening the chapter work site was relocated to the new facility. Prior to his role as president, Jacob led a team of engineers to develop a treadle pump system for water filtration and backflow cleaning. Jacob continues to support the chapter informally with engineering and technology development consultation.

EWB-JSC President, 2010-2011

Dan Garguilo

While presiding over the chapter, Dan oversaw chapter expansion to include a new region, Aguilar, Mexico, and a technology project in Mugonero, Rwanda. The water filtration system developed in Rwanda was successfully adapted and implemented in Mexico utilizing an electrical power source in place of the gravity feed structure. The Rwanda village fully embraced the prior projects delivered by the chapter and sought further involvement from the team. Through a collaborative review with Dan, the project lead, and the village management team, a project to dehydrate pineapple fruit was established. The project would continue to develop over the years with an ultimate goal of providing a sustainable income source to allow the orphanage financial independence. Multiple assessment and implementation trips were successfully organized and completed to Rwanda and Mexico. Dan continues to support the chapter informally with organizational consultation.

EWB-JSC President, 2008-2010

Evan Thomas

As founding president of the chapter, Evan brought the engineering and insight of the NASA Johnson Space Center manned space flight program to the developing world. The chapter established a relationship with The L’Esperance Orphanage in Mugonero, Rwanda. The relationship grew to generate projects to provide solar power lighting to the local hospital, rain water catchment, and water purification for the village. The Bring Your Own Water system was invented, and the technology was successfully implemented. Evan continues to support the chapter informally with technology and organizational consultation.
