1. MINI-HYDRO. GOING WITH THE FLOW
Andrew Gonzales, Candace Kaiser, Andrew Cannard

2. 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[1]
 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?

3. CAN WE COLLECT ENOUGH RUNOFF WATER TO
PRODUCE ENERGY?
H1-Yes, there will be enough water to produce a
useable amount of energy.
H2-Yes, energy will be produced but not much
Null Hypotheses- No, there will not be enough water
to produce energy

4. CAN WE MAKE A LOW COST MINI-HYDRO
SYSTEM 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

5. WILL THIS HOMEMADE TURBINE PRODUCE ANY
ENERGY?
 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

6. 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.

7. 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

8. 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.

9. OUTCOME
 Our goal is to create a micro hydro turbine which
can be used to demonstrate the possibilities of
micro hydro energy on campus.

10. 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

11. 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
