2. History Started May ’08 and continued through summerStarted May ’08 and continued through summer Class entered the Lemelson MIT Inventeams competition, we were eliminated in the second roundClass entered the Lemelson MIT Inventeams competition, we were eliminated in the second round We decided to pursue the project even with the loss of fundingWe decided to pursue the project even with the loss of funding We have prepared many prototypes to implement into the system, testing them in conjunction with the physics classWe have prepared many prototypes to implement into the system, testing them in conjunction with the physics class At this time we are ready to create a “real life” full scale modelAt this time we are ready to create a “real life” full scale model

3. General Purpose  The purpose of this system is to capture otherwise wasted energy leaving the house in the form of water from the toilets, sinks, and showers.  This water will create energy and be used in the house instead of energy from a grid.

4.  The water is filtered using a specialized separator system  The water is stored in a large storage tank before being used in the system.  After the filter process, the clean water will be ran through a generator creating electricity that will supplement electricity in the house. General Purpose Cont’d

5. Infrastructure Infrastructure In order of use 1. Holding tank - Represents all “brown water” from house. 2. Filter - separates solids and liquids solids and liquids 3. Siphon holding tank - uses siphon to create uses siphon to create maximum power maximum power 4. Generator - Uses falling water to produce energy Uses falling water to produce energy 5. Recirculation tank - used only for display 1. 2. 3. 4. 5.

6. Infrastructure  The infrastructure provides a supportive layout that allows the water to flow through our system  Using gravity the water flows from the top to the bottom of our system  This particular model is still in it’s early stages and when placed in a home or building will be much smaller and compact

9. Holding Tank (Display only)  Beginning of system  This tank represents water from a house.  Provides the system with water to run the impeller.

10. Holding Tank Funnel Plug

11. Funnel Separator Filter: Filter: -Utilizes perforated funnel to separate large solids from water -The water slides through holes in funnel holes in funnel and leaves out of the side of the drum of the drum -The solids slide down the funnel, down through the center hole and out the bottom of the drum

15. Siphon Holding Tank - Stores small increments of water - After water reaches the desired level a float lifts a plug and initiates the siphon effect to empty the water into the generator - Siphon effect creates velocity and allows velocity and allows water to pull itself water to pull itself out of the tank and out of the tank and into the generator into the generator

17. Impeller and Generator Includes:  An impeller spun by the falling water.  A motor spun by the impeller to generate electricity.  Process must be efficient.

18. Impeller  Has 9 fins  Each fin is concave  Goal is to spin this as fast as possible  Impeller will spin motor to produce energy

24. Re-circulating Pump -Meant for display purposes only -The goal of model is to create enough power for the system to be self sustaining

25. Project Materials Fiberglass mat – to construct the “toilet bowl” Resin & Hardener – for fiber glass Bondo – to give smooth shape and texture to fiberglass Foam mold – to create toilet bowl shape before fiberglass application PVC tubing – to transport water throughout the system 2X4’s – for structure and support of the system 55 gal drums – to hold the water at various points Plastic – To mold impeller & housing
