High Tech High Touch: Lessons Learned From Project Haiti 2011, Yan Tang, Marc Compere, Yung Lun Wong, Jared Anthony Coleman, Matthew Charles Selkirk

In this paper, we will share our experiences and lessons learned from a design project for providing clean water to a Haitian orphanage (Project Haiti 2011). Supported by funds from a renewable energy company and the university president’s office, five engineering students and two faculty members from Embry-Riddle Aeronautical University successfully designed and installed a solar powered water purification system for an orphanage located in Chambellan, Haiti. This paper discusses the unique educational experiences gained from unusual design constraints, such as ambiguity of existing facilities due to limited communication, logistics of international construction at a remote village location, and cross-cultural …

Entrochemical systems are systems capable of generating internal thermal gradients through internal
water movements which simultaneously transfer get of vaporization between internal water reservoirs. These systems move to a chemical equilibrium state that generates and maintains a thermal gradient. Entrochemical thermal batteries (ETB) can be constructed which extend the thermal gradient of a single cell through an additive process. Such systems can deliver useful work. Additionally solutions used therein may be recharged passively using environmental heat.

We describe the design and function of a bench-scale water heater capable of heating a small water
reservoir. The system is powered by an …

We report the design and function of a distillation apparatus which uses salt concentration gradients to
drive distillation and desalination of simulated sea water. Utilizing the entrochemical effect, the system
generates an internal thermal gradient. An internal distiller is arranged with the condenser in the cold end of the
entrochemical system and a seawater reservoir in the warm end of the entrochemical system. The heat of
vaporization is recaptured in the cold side of the entrochemical system and re-used. The spent solution in the
entrochemical system can be recharged using evaporation, making the surrounding thermal energy the source
of energy …
