Presentation Transcript

  1. Presented to: • OPP • EDSGN 100 • 8/8/11 Energy to Educate Craig Hammond Stephanie Sheppard Kyle Tress Justin Valenti

  2. Table of Contents • Wind • Wind types • Micro Hydro • Power Control System • Final Design

  3. Goals • Supply self sustainable energy • Enhance cultural understanding • Marketable • Educational • Affordable

  4. Wind Energy What wind is Wind power generation- Wind Turbine Advantages and challenges Personal Use

  5. Wind How it’s formed Uneven heating of the atmosphere Irregularities of the earth’s surface Rotation of the earth How wind flow patterns are determined Earth’s Terrain -Bodies of water -Vegetation How it's captured to create electricity Wind Turbine

  6. Wind Turbine What it is -Device that converts kinetic energy from wind into mechanical energy.

  8. Advantages and Challenges PROS Renewable energy Abundant Low-priced long term CONS May not be cost competitive Higher initial investment Wind is inconsistent

  9. Personal Wind Systems • Provides energy for personal use • Requires consistent Wind around 9mph for best use Skystream 3.7 Wind Turbine

  10. Educational opportunities on Wind • Interactive wind Turbine • Shows Moving Parts • Powers lights • Wind Pump • Shows more wind creates more power • Gears

  11. Rethinking Wind Energy Vertical Axis Wind Turbine (VAWT) Recently popular Used more on the residential level Lower Cost No need for direction Horizontal Axis Wind Turbine (HAWT) • Traditional Design • Commercially used • Quite Expensive • Needs to be directed into the wind

  14. 250W DC Barrel Turbine http://www.silentwindturbine.com/250w-barrel-turbine.htm

  15. Micro Hydro Power System Convert potential energy from water flow Great alternative energy source Turbine  Generator  electricity Head and flow of stream Constant AC power www.homepower.com

  16. Energy Output P = Q * H * e * g P = Power at generator terminal (kW) Q = Volume flow in pipeline (m3/s) H = Head (m) e = efficiency g = 9.81 m/s2 (gravity constant) http://www.ems.psu.edu/~elsworth/courses/cause2003/finalprojects/vikingpaper.pdf

  17. Head- vertical distance the water falls Higher heads require less water to produce a given amount of power. www.homepower.com

  18. www.mindspeak.com Educational Opportunities Demonstrations Marbles Water Wheel Mini Micro Hydro system http://homepower.com/basics/hydro/ www.sullivanswaterwheels.com

  19. Fun Fact: Hoover Dam generates 4.2 billion kW hours annually The Flow powerelectrical.blogspot.com www.homepower.com Fun Fact: Hoover damn has Peltonwater wheels (impulse turbine). technologysector.blogspot.com • Intake • Pipeline • Turbine • Impulse • Water wheel • Reaction http://www.usbr.gov/lc/hooverdam/faqs/powerfaq.html

  20. Power Pathway

  21. Where Is The Power?

  22. Controlling the power Charge Controller Preventing overcharge Preventing Reverse flow Did you know that Solar Panels remove charge from a battery at night? Low Voltage Disconnect Solar Power  Cut power at 80% diminished or 20% of total charge Wind Keep constant load (Dump Load) Windy Dankoff. “What is a Charge Controller”

  23. Educational Opportunity!!!! How much power is created from the various inputs?

  24. Battery Bank Basics Constraints Safe containment John Meyer and Joe Schwartz. “Battery Box”

  25. Design Process • Brainstorming • Traditional Windmill • Helix Windmill • Geothermal • Micro Hydro • Playground • Water Tower • Helix Water Tower Windmill

  26. Criteria • Ease Of Use • Power Consumption • Power Provided • Manufacturing Ease • Maintained • Space consumption • Durability • Cost • Reliability • Sustainability

  27. Final Design • Micro Hydro • Battery Bank • Wind Mills • Helix • Traditional
