Project Description• Identify methods to harvest waste

power generated by people for end use in Haiti.

• Low cost designs to improve quality of life such as:o Water Sanitation o Energy Generationo Portable Dry Toileto Rain-water Collection

Urine Diversion (UD) Toilet from SOIL

Background • Living conditions in Haiti

o Poverty stricken (GDP per capita of $1200)o Ineffective central government.o Little law enforcement.o Untreated water sources contaminated with

animal and human waste.o No active sewage system.o Most people are subsistence farmers. o Many people have cell phones. o No electricity in homes.o Very little education available. o Very religious.

Background cont.UV sanitation pumps are currently being

developed by B9 Plastics and RIT to eliminate bacteria in dirty water and make it safe to drink.

Past Project Concentrations• Harvesting Energy From:

o Humans Non-Invasive Movement

• Normal to Everyday Lifeo Energy Harvesting Backpacko sOccet Soccer Ball

o Moving Water Stream Power

P12461 Waterbelt - Aerostatic Flutter Hydro-Power Generator

P11412 • Improve UV Water Sanitation System:

Senior Design Project o This project revolved around the

improvement of a current UC Berkeley project to eliminate contamination in the event of component failure.

Sanitation in Haiti• From 1998-2008 the percent of Haitians that

had access to "improved sanitation" went down from 45%-24%

• Only 14% of rural Haiti has access to "improved sanitation"o 'Improved Sanitation' means any sort of

waste sanitation beyond squatting in a bucket

• Today over 70% of Haiti is without proper sanitation

Agriculture in Haiti• 1950's: Employed 80% of Workforce, 50% of Nation's GDP, 90%

of Exports

• 1980's: Employed 66% of Workforce, 35% of Nation's GDP, 25% of Exports

• Today's decline in Haitian Agriculture is due to:o Extreme deforestationo Soil Erosiono Droughtso Floodingo Natural Disasters

Composting & Toilets in Haiti• Haitians have a need of a proper toilet (lavatory, lav, can, john,

privy, bathroom, commode, crapper, pot, potty, stool, throne, head, loo, plopper) for defecation and urination

• Due to the lack proper sanitation systems Haitians inevitably find the need to dispose of their... waste products

• To do so a common practice is to implement a:

Humanure Composter!!!• Using the waste from the toilet as fertile

soil for agricultural needs

Stakeholders• Sarah Brownell - Worked in Haiti for

10 years. • B9 Plastics - Sponsor for the UV

water disinfection design (Better Water Maker).

• Alex Martinez - Student in with a toilet and composter concept.

Next Steps• Determine what project path holds the

highest potential for major impact in the Haitian community and/or developing nations worldwide.

• Generate engineering specs from customer needs
