You will need to set up a model wind turbine and a fan. You need a tower, a generator, a rotor, and of course wind! No matter what kind of model turbine you build, it will require some of the same parts as a real wind turbine. There are many different plans and designs for wind turbines, but they all share a few things in common. Knowing how sensors and multimeters work can make this much easier.įor the wind and solar competitions we have a maximum voltage and current limit that is important to stay below for safety reasons and so you do not get disqualified! In the solar portion of the KidWind Challenge we ask quite a few questions about how much load your solar structure can power and the current and power consumption of various loads in your device. All you need is a basic multimeter and some resistors. The Go Direct Energy Simulator simulates this experience in your classroom but if you do not have one you can use our performance calculator which will help you approximate the power output and energy production of your turbine. We will put your turbine in a wind tunnel and see how much energy it generates over a period of time. We recommend classes have at least one Go Direct Energy Sensor and then 4-5 multimeters.įor the wind portion of a KidWind Challenge a large component of your score is turbine performance. It also has a built-in 30 ohm test load so you can put your solar panels or wind turbines under load. The great thing about this device is it allows you to collect voltage, current, power, energy and resistance simultaneously and compare the data over different trials.
It connects to all devices and is an easy way to collect detailed turbine and solar panel electricity data. While we love the cost and ease of a simple multimeter, we really love Vernier’s Go Direct Energy Sensor (GDX-NRG). You can use a simple multimeter or data logging equipment to collect this data. It is also very handy to be able to measure the power consumption of various loads you may attach to these devices. To succeed at a KidWind Challenge it is very helpful to measure the power output from your wind turbine and solar panels.
