Paper Windmill – Summarize Spoken Text

PTE SST – Paper Windmill

Wind turbine is a device that will convert wind into mechanical movement, which we can use to power water pump or electricity generator. Now the power that the turbine creates is obviously dependent on the wind speed, it’s also dependent obviously on the number of sails, the area of the sails and the angle of the sails makes to the wind. So if you can imagine if the turbine blades are flat onto the wind, the wind is just gonna sort of bend it, but if there is slight angle when the wind hits it, it’s gonna turn the blades. We can use that for powering things. Now, we’re gonna have a go, making some very, very simple paper windmills, a sort of things you can make from the bits and pieces lying around at home, and use that to drive a very small generator to power electronic devices.
