Dartmouth Humanitarian Engineering (DHE)

Dartmouth Humanitarian Engineering (DHE) DHE is a group of university students committed to bringing sustainable, affordable, socially-consci Coli.

Tanzania - Stove Project
DHE has been involved in developing and implementing improved cookstoves for the past 3 years. We are working to introduce stove designs in communities in Western Tanzania that use local materials and burn cleaner and more efficiently. We are currently working on one design that burns wood and one that burns coffee husks. We aim to reduce deforestation by finding alternati

ves to wood as a fuel while also finding ways to burn wood more efficiently in places where alternatives are not available. Additionally, we are designing our stoves to improve indoor air quality by burning more cleanly than conventional three-stone stoves. It is our hope that our stoves can both improve the health of ecosystems and the health of the communities in which we work. Rwanda - Pico-Hydro Project
Over a billion people currently live without access to electricity, and due to the manner in which power is currently distributed, many of these people are unlikely to receive access to power in the near future. Small-scale hydroelectric systems can supply electricity in a simple, inexpensive, and sustainable way. With support from 5th year engineering students, the Pico-Hydro group is currently partnering with the student group e.quinox to install a hydroelectric system in Rwanda. Tanzania - Water Project
One goal of DHE has been to provide a clean water solution for two villages in Tanzania, Mwamgongo and Kalinzi, which suffer from disease and illness associated with contaminated water. In the Spring/Summer of 2010, DHE conducted extensive water testing of the Mwamgongo tap system and the protected spring system in Kalinzi and discovered the presence of fecal coliform - an indicator of pathogens such as E. Currently, DHE is attempting to develop a water purification system that can be used on an individual basis to address this problem. SODIS (solar water disinfection) uses UV radiation to kill pathogens in drinking water and is one solution we are pursuing! We are also beginning to research water catchment systems to complement SODIS in the rainy season. Tanzania - Wind Project
The Wind group was initiated to research the possibility of harnessing the wind power in Tanzania in order to generate electricity to charge batteries for the citizens of the surrounding communities. The group has decided to use horizontal axis wind turbines--horizontal turbines are more complicated and work most efficiently at higher altitudes, but the power payoff is significantly greater than vertical axis turbines. The Wind group sent an anemometer to Tanzania with Molly Wilson ’13 to measure wind speeds and direction. While Molly sets up the equipment, the rest of the group in Hanover is surveying locations for a setting up local site. We hope to have a working windmill generating 300 Watts by the end of Spring Term. We are currently looking for another anemometer to test wind speed around Hanover, hoping to find wind patterns similar to those in our chosen location in Tanzania. Lastly, we are going to start constructing our first turbine this term at Thayer School of Engineering.

So honored to work with such an incredible organization as Upper Valley Haven! We're all super excited to continue to work on the Cot Project this Spring Term!

Being at Dartmouth can be all-consuming, as we worry about our own responsiblities and futures. Even walking into Hanover doesn’t really bring a lot of variety; it’s a small, wealthy town with many of its buildings owned by Dartmouth.

The Cot Project team is working with a local homeless shelter, the Upper Valley Haven, to design a durable, storable cot for temporary shelters.

Over the past few terms, we’ve created non-intrusive improvements to existing cot designs, and even designed our own stackable cot! We’re super excited to start user testing this winter at the Haven! @ Thayer School of Engineering at Dartmouth Alumni

The Hydroponics team has traveled to Quito, Ecuador for a research trip. We’ve spent the past few days meeting with our partner NGO, CONQUITO, collaborating with professors and students from USFQ, and exploring gardens across the city!

Not your grandfather’s fertilizer!
The hydroponics team is building a device that creates compost tea, which can be used to deliver nutrients in hydroponic systems or diluted and used as fertilizer!

Now, they have finished building the second prototype and tested growing basil from it’s first batch of compost tea. They hope to visit Ecuador this summer to do some research for potential implementation in Quito.
