MINI-HYDRO. GOING WITH THE FLOWAndrew Gonzales, Candace Kaiser, Andrew Cannard
RAIN RUNOFF DOES PRODUCE ENERGY… A significant amount of water can be collected and used for alternative use. King Street Center: 44,000 ft.^2 roof 37 inches annual rainfall 1.4 million gallons collected annually Micro Hydro systems are becoming increasingly common in small developing communities. Most systems are run by streams or other natural water flow systems.Questions about rain water runoff: Is there enough runoff water to produce energy? Can we make a low cost turbine with re-purposed materials? Will this homemade turbine produce any energy?
CAN WE COLLECT ENOUGH RUNOFF WATER TOPRODUCE ENERGY?H1-Yes, there will be enough water to produce a useable amount of energy.H2-Yes, energy will be produced but not muchNull Hypotheses- No, there will not be enough water to produce energy
CAN WE MAKE A LOW COST MINI-HYDROSYSTEM WITH RE-PURPOSED MATERIALS? H1-Yes, we can build a system with only re- purposed materials. H2-Yes, we can build a system but not solely with re-purposed materials Null Hypothesis-No, we cannot build a functional system with re-purposed material http://www.thestonestore.com
WILL THIS HOMEMADE TURBINE PRODUCE ANYENERGY? H1- Yes, but homebuilt not as efficient as professional H2- Yes, but homebuilt is extremely inefficient Null Hypothesis- No, so inefficient that it will not produce energy http://www.doradovista.com/DVPower2.html
HOW CAN WE TEST OUR HYPOTHESES? Calculate ideal energy production from a given water source (roof top). Compare prices of commercially available turbines with our homebuilt turbine. Measure energy production with our homebuilt turbine measured with a multi-meter. Compare values from calculations and measurements.http://www.renewcanada.com http://www.renewablesfirst.co.uk
BUDGET Repurposed and Recyclable Materials Old bicycle for water wheel- cheap on craigslist Used automotive alternator- $25 Miscellaneous household items for water wheel-$50 Copper wire- $5 Lab Stores Free for rent or low cost Multi meter Water flow meter Ingenuity Manipulating materials in an effective way to make them have a new purpose
BENEFITS OFMICRO HYDRO Uses an abundant natural resource in our area to produce energy. Micro hydro systems using rain water runoff from buildings will have no environmental impact on natural habitats. http://www.dropyourenergybill.com/archives/1546
OUTCOME Our goal is to create a micro hydro turbine which can be used to demonstrate the possibilities of micro hydro energy on campus.
OUTREACH AND EDUCATION Stepping Stones First step to utilizing the abundant natural resource of rain in our local community Design for Others Replicable design for creating multiple units Mobility Easy to use by other Evergreen Students in the Future Inspiration Future Projects Discovery of low-cost renewable electricity
CAMPUS SUSTAINABILITY GOALS Promoting Education and Research for the Future Laying the groundwork Future students would have a resource as to the effectiveness of on campus micro-hydro 100% of Electricity at evergreen is BOUGHT from renewable energy sources Micro hydro could increase renewable energy production on campus More money for other areas of the Climate Action Plan
