Wind energy offers a viable, economical alternative to conventional power plants in many areas of the country. Activity, High School Duct tape a rectangular piece of cardboard to each Popsicle stick at such an angle as to create spin when wind blows past it. PVC 6-inch-long pipes Wind turbines need wind speeds of at least 15 kilometers (9 miles) per hour, for small wind turbines, and 21 kilometers (14 miles) per hour, for utility-scale turbines. This will help us understand what engineers need to know when designing and placing wind turbines in the best locations. • Hot glue/glue gun PVC 90-degree fittings You can measure how much electricity (voltage) is produced with a voltmeter. I found a great piece of property. Snake the motor's wires down the 24-inch PVC pipe; this long section is the tower.2. How might you alter your turbine design or position to better capture the wind and produce more voltage? Design small scale wind turbine for home electricity generation 1. The project researched blade designs that performed the best with a 90° enclosure. Have students share and compare their designs by giving brief engineering reports to the class. turbine: A machine in which the kinetic energy of a moving fluid is converted into mechanical energy by causing a series of buckets, paddles or blades on a rotor to rotate. Explore how wind velocity affects the amount of electricity produced by changing fan speeds. If the wind speed doubles, the power available to a wind turbine increases by a factor of eight. Students should never touch any bare or exposed metal in a circuit that is generating electricity. Related Curriculum shows how the document you are currently viewing fits into this hierarchy of curricular materials. The wind turbine will generate enough alternating current, or AC, to power a small light bulb. Infinite Power, Texas State Energy Conservation Office. potential energy: Potential energy is the energy stored by an object as a result of its position. Accessed October 20, 2005. Did the turbine design of any team produce more voltage at the same distance, compared to the rest? • Six 1-inch-dia. For lower grades, have the motor setup already prepared. He tried several designs that included six vanes and wide vanes but the simplest was still the most efficient. • Three 1-inch-dia. Students document their final wind turbine design, as well as the data collected that lead them to settle on this particular design. WinDIY is a design of a (mostly) 3D printed wind turbine. So, when does a wind turbine work best? (Answer: As high up as possible, such as on a pole above the roof, or on a separate structure that puts it up very high in the air.). For example, a spinning top, a falling object and a rolling ball all have kinetic energy. This increased airflow (wind) can be equivocated to wind turbine generators. For upper grades, have students graph the voltage produced as a function of fan distance. Link to project packet - focus on expense report, rationale sections. That's pretty high up. • Multimeter Updated October 3, 2005. K - Clean Air-Cool Planet. Free K-12 standards-aligned STEM curriculum for educators everywhere. Push the cork into the motor shaft. Wind turbine designs have progressed from fixed speed, passive controlled and with drive trains with gearboxes, to become variable speed, active controlled, and with or without gearboxes, using the latest in power electronics, aerodynamics, and mechanical drive train designs [4]. within type by subtype, then by grade, etc. PVC 24-inch-long pipe From: Wind Energy Engineering, 2017. Then, we will measure how the wind speed affects our little wind turbines. The power produced by a wind turbine depends on elevation, wind speed and air temperature. Apply scientific ideas to solve design problems. Accessed October 19, 20015. A turbine with a shaft-mounted horizontally parallel to the ground is called a horizontal axis wind turbine or HAWT. • Poster board for blades ), If we remove the motor from the rotor of the wind turbine, we will not be able to produce electricity, but we will still be able to do work with our windmill. (Note: The voltage that your turbine produces depends on the torque and RPM of the blades. Turn on the wind source and measure the voltage produced. The project is to design a wind turbine, I need only two steps from the whole project. and also charge a mobile phone with wind energy with few modifications. Set up a test station with a voltmeter and a wind source (fan or hair dryer) where teams can take turns measuring the output of their wind turbine generators. Review each team's results and observations. For one team at a time, use alligator clips to attach the free ends of the wires to a DC voltmeter. Thread the wires attached to the DC motor into the mouth of the coupler, all the way through the 90-degree PVC fitting.5. kinetic energy: The energy of motion. Math Worksheet (pdf), Scaling Activity: Wind Power! Have them discuss their answers in teams and share their thoughts with the class. Have students use a rubber band to attach the electric motor to the ruler with the motor shaft positioned at the end of the ruler (see Figure 1). Some activities or lessons, however, were developed to stand alone, and hence, they might not conform to this strict hierarchy. Do you agree with this alignment? The ruler serves as a platform for the wind turbine. Wind power is one of the fastest-growing energy sources in the world. 3 - These turbines are not to be pointed into the wind because of their improved aerodynamic design. Drill a small hole on the bottom of the last PVC tee.4. 1.0.1 INTRODUCTION Wind … 4-PS3-4. The rotating action of the hub turns a magnet inside a coil of wire in the generator, producing electricity.
