Title of Activity:

Project Progress.

ü  Analysis the output of the Wind Turbine and the Thermoelectric module

Objective:

• Determine the problem and improve the output of the Wind Turbine
• Analysis the Thermoelectric module output

Content/Procedure:

• Try to improve the output of the Wind Turbine by changing the value of coils.
• Change the magnet by using the rare earth magnet (neodymium).
• For the thermoelectric module, use the dry ice and the hair dryer (to get a huge temperature different).

Picture of the Dry Ice

Picture show the Thermoelectric module gain the output using the dry ice and with hot air

Picture of the Thermoelectric module output is 1.07V

Picture of the Thermoelectric module output is 153.9mA

Picture of the Thermoelectric module output is up to 0.21A

Result and Analysis:

The output of the Wind Turbine showed in the video below:

As a result, the wind turbine has gained the output that can operate the L.E.D on. The output have been gained more by upgrading the stator part (add the coils from 4 up to 8 coils), and changing the magnet by using the rare earth magnet (neodymium). As we can see from the video, the L.E.D begins to light on when the output are above 0.6V. This process begins from a dim L.E.D and then the L.E.D becomes brighter when the rotations of the wind turbine are faster and the higher output is gained. If the output voltage are below 0.6V, the L.E.D will be turn off.

And for the thermoelectric module, the output has been gained more higher when we apply the higher different temperature. In this week, we have tried to use the dry ice and the hot air from the hair dryer. As a result, the output voltages that have been gained are 1.07V (showed in picture above). And the output current is around 153.9mA to 0.21A and this result is also showed in the picture above. 

Conclusions:

As a conclusion, the outputs for the wind turbine have been improved by changing their number of coils in the stator parts. And the arrangement for the coils is also had been corrected. All these have improved the output result for this week.
