Cadd 3 Inventeams Presentation

  1. 1. CADD III G enerating R enewable E nergy E fficiently N ow G.R.E.E.N. Project Itinerary
  2. 2. History <ul><li>Started May ’08 and continued through summer </li></ul><ul><li>Class entered the Lemelson MIT Inventeams competition, we were eliminated in the second round </li></ul><ul><li>We decided to pursue the project even with the loss of funding </li></ul><ul><li>We have prepared many prototypes to implement into the system, testing them in conjunction with the physics class </li></ul><ul><li>At this time we are ready to create a “real life” full scale model </li></ul>
  3. 3. General Purpose <ul><li>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. </li></ul><ul><li>This water will create energy and be used in the house instead of energy from a grid. </li></ul>
  4. 4. <ul><li>The water is filtered using a specialized separator system </li></ul><ul><li>The water is stored in a large storage tank before being used in the system. </li></ul><ul><li>After the filter process, the clean water will be ran through a generator creating electricity that will supplement electricity in the house. </li></ul>General Purpose Cont’d
  5. 5. Infrastructure In order of use <ul><li>1. Holding tank - Represents all “brown water” from house. </li></ul><ul><li>2. Filter - separates </li></ul><ul><li>solids and liquids </li></ul><ul><li>3. Siphon holding tank - </li></ul><ul><li>uses siphon to create </li></ul><ul><li>maximum power </li></ul><ul><li>4. Generator - </li></ul><ul><li>Uses falling water to produce energy </li></ul><ul><li>5. Recirculation tank - used only for display </li></ul>1. 2. 3. 4. 5.
  6. 6. Infrastructure <ul><li>The infrastructure provides a supportive layout that allows the water to flow through our system </li></ul><ul><li>Using gravity the water flows from the top to the bottom of our system </li></ul><ul><li>This particular model is still in it’s early stages and when placed in a home or building will be much smaller and compact </li></ul>
  7. 7. Infrastructure Image Holding Tank Holding Tank (Display Only) Filter Separator Siphon Tank Recirculation Tank (Display Only) Impeller
  8. 9. Holding Tank (Display only) <ul><li>Beginning of system </li></ul><ul><li>This tank represents water from a house. </li></ul><ul><li>Provides the system with water to run the impeller. </li></ul>
  9. 10. Holding Tank Funnel Plug
  10. 11. Funnel Separator <ul><li>Filter: </li></ul><ul><li>-Utilizes perforated funnel to separate </li></ul><ul><li>large solids from water </li></ul><ul><li>-The water slides through </li></ul><ul><li>holes in funnel </li></ul><ul><li>and leaves out of the side </li></ul><ul><li>of the drum </li></ul><ul><li>-The solids slide down </li></ul><ul><li>the funnel, down through the center hole and out the bottom of the drum </li></ul>
  11. 12. Funnel Separator Perforated Funnel Perforated Pipe Water Ramp Separator Housing Water Exit Solid Exit
  12. 15. Siphon Holding Tank <ul><li>Stores small increments of water </li></ul><ul><li>After water reaches the desired level a float lifts a plug and initiates the siphon effect to empty the water into the generator </li></ul><ul><li>Siphon effect creates </li></ul><ul><li>velocity and allows </li></ul><ul><li>water to pull itself </li></ul><ul><li>out of the tank and </li></ul><ul><li>into the generator </li></ul>
  13. 16. Siphon Holding Tank Image Flush Tank Siphon Jet Plug Arm Float Water Exit Bowl Float Valve
  14. 17. Impeller and Generator <ul><li>Includes: </li></ul><ul><li>An impeller spun by the falling water. </li></ul><ul><li>A motor spun by the impeller to generate electricity. </li></ul><ul><li>Process must be efficient. </li></ul>
  15. 18. Impeller <ul><li>Has 9 fins </li></ul><ul><li>Each fin is concave </li></ul><ul><li>Goal is to spin this as fast as </li></ul><ul><li>possible </li></ul><ul><li>Impeller will spin motor to </li></ul><ul><li>produce energy </li></ul>

  18. 21. Motor/Generator <ul><li>Spun by the Impeller previously viewed </li></ul><ul><li>Electricity provided by this device will be sent directly into house for immediate use </li></ul><ul><li>Loss of funding impeded investigation of this area </li></ul>
  19. 23. <ul><li>Prototype impeller and generator. </li></ul>A. B. C. D.
  20. 24. Re-circulating Pump <ul><li>- Meant for display purposes only </li></ul><ul><li>-The goal of model is to create enough power for the system to be self sustaining </li></ul>
  21. 25. Project Materials <ul><li>Fiberglass mat – to construct the “toilet bowl” </li></ul><ul><li>Resin & Hardener – for fiber glass </li></ul><ul><li>Bondo – to give smooth shape and texture to fiberglass </li></ul><ul><li>Foam mold – to create toilet bowl shape before fiberglass application </li></ul><ul><li>PVC tubing – to transport water throughout the system </li></ul><ul><li>2X4’s – for structure and support of the system </li></ul><ul><li>55 gal drums – to hold the water at various points </li></ul><ul><li>Plastic – To mold impeller & housing </li></ul>
