goals
Goals
  • To have a working Stirling Engine that will serve as a portable generator capable of producing 2.5 kWh
  • To be able to run multiple common household appliances simultaneously
household appliances
Household Appliances
  • Appliances (average):
    • Refrigerator/Freezer = Start up 1500 Watts
      • Operating = 500-800 watts
    • Hot plate = 1200 Watts
    • Toaster oven = 1200 Watts
    • Space heater = 1500 Watts
    • Air Conditioner (5,000 BTUH room unit) = 900 Watts
  • Lights = Most common are 60 watt light bulbs.
    • Most rooms/areas on breaker boxes consist of 4-5 light bulbs => 240-300 Watts
  • Tools (average):
    • ¼” drill = 250 Watts
    • ½” drill = 750 Watts
    • 1” drill = 1000 Watts
    • Electric Chain Saw 11”-16” = 1100-1600 Watts
    • 7-1/4” Circular Saw = 900 Watts

background
Background
  • Created by Robert Stirling in 1816
    • His brother, James Stirling, created a Stirling Engine that powered a foundry
  • ASE- Automotive Stirling Engine
    • Program created by NASA and the United States Department of Energy
  • Incorporated in many submarine applications
    • Propulsion system
    • Very quiet
    • Increased efficiency

how it works
How it Works
  • The displacer cylinder is heated by an external heat source
  • The working gas expands in the cylinder creating pressure resulting in movement of the displacer
  • The working gas forces the displacer in both directions
  • The cylinder with the power piston compresses and contracts with the change in temperature
  • This is due to the rejected heat leaving the system through convection
  • The system restarts this cycle

alpha
Alpha
  • Enclosed system with two cylinders that has corresponding pistons which compress and contract with change in temperature
slide14
Beta
  • One cylinder system that encloses one piston and displacer
gamma
Gamma
  • Similar to the Beta but with two cylinders that have a chamber which funnels working gas into the power piston cylinder
