Newberg High School
Newberg, Ore.
Portable, Lightweight Solar Stirling Generator
to Provide Electricity to Remote Villages

  • The invention stemmed from an in-class assignment to build Stirling engines, which Newberg High School has a history of building.

  • The InvenTeam combined a Stirling engine with a three-foot parabolic dish to create a solar-powered device that generates low-cost, sustainable energy.

  • The invention generates the sun's energy through a pair of photo-resistor sensor rays and a reflective nickel-plated finish on the parabolic dish.

  • On a clear day, the Stirling engine speeds up to 700 RPM.

  • The InvenTeam received a 2009 Continuation Grant.
