Gulf Coast High School InvenTeam

Poor indoor air quality has often been a cause of health problems. Air-born particles from dust and chemical preservatives can cause respiratory dysfunctions, such as asthma and allergies, for many people. Student Genevieve Garris had realized this problem and introduced it to her team, since her household chore was to clean the fans.

Summit High School InvenTeam

  • The HEGU, which stands for Hybrid Electrical Generation Unit, was conceived as an aesthetic charging station for hybrid cars that could potentially serve as a portable generator for disaster areas, too.
  • HEGU was inspired by the Cal-Cars Initiative, which aims to use less fuel when driving a car.
  • Standing 25 ft. tall, the HEGU prototype-power tree includes a 632-watt solar panel, 400-watt wind turbine, 6000-watt bio-diesel generator, 2400-watt inverter and marine batteries (which were slated to be replaced by lead-acid batteries).

Nerinx Hall High School InvenTeam

  • The Water Treatment and Transportation Apparatus (WTTA) was inspired by two students who visited southern Mexico during a spring-break service trip and witnessed many problems within the community.
  • The WTTA was designed to ease the burden of women who were tasked with hauling five-gallon buckets of water to their homes as needed; and moreover, to provide cleaner water that would not cause their families to be sick.

Moscow Senior High School InvenTeam

  • The fact that Kentucky bluegrass is a common agricultural product of Idaho farmers served as the premise for the InvenTeam’s invention.
  • Field burning has been the preferred farming method because it is more economical and practical than other methods, such as tilling. However, burning fields of Kentucky bluegrass releases toxins that cause pollution, which can lead to respiratory ailments.

Johnson High School InvenTeam

  • The InvenTeam looked internally to solve a problem within its school: Each year the school spent close to $5,000 on wood for its wood shop class and other projects, of which 30 percent was rendered useless as accumulated sawdust.
  • In a quest to create a product that was less dependent on energy and utilized recycled materials, the students’ Eureka! moment brought the realization that a complementary use of heat and pressure will cause the sawdust to bind to itself in lieu of using a petroleum-based material such as wax to mold the sawdust together.

Sehome High School InvenTeam

  • The InvenTeam's device surveys a location for its solar energy potential by determining solar obstructions–including trees, houses, mountains, etc.
  • Advanced Circuits sponsored the circuit board production of the surveyor, and Garmin – a GPS designer/manufacturer – provided a GPS at reduced cost.
  • The InvenTeam plans to develop multiple surveyors that can communicate wirelessly, and will determine the best solar-energy location, rather than assessing the solar energy potential of a single location.

Newberg High School InvenTeam

  • 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.

Merrimack High School InvenTeam

  • Driven by a mission "to raise awareness and use of carbon-neutral alternative fuels," the InvenTeam designed a 500-mL processor operated by a 12-volt battery.
  • The InvenTeam has been testing the biodiesel in an old Air Force bus that it secured from Jefferson Barracks in St. Louis, Mo., with the help of teacher Ray Sleeper.
  • Since the InvenTeam's presentation at the Odyssey in June 2007, the students have increased the biodiesel concentration from 30 to 50 percent, with an aim of using 100 percent biodiesel.

Gresham High School InvenTeam

  • Known as the Smart Watering Irrigation System (SWIS), the device analyzes the soil-moisture content through moisture sensors.
  • When the soil moisture reaches the 30 percent threshold, water is no longer distributed to the plant.
  • Local nurseries sponsored and consulted on the project, and Vernier provided the InvenTeam with design equipment.
  • For its next steps, the InvenTeam plans to create an Internet interface so consumers can monitor their plants remotely.
