Goal and Material

The goal of this experiment is understanding  the relationship between light intensity and the voltage output of the solar cell.

For the material, we have

  • One solar cell
  • One voltage probe
  • One NXT adaptor
  • NXT with light sensor
  • One light source
  • Labview VI vi
  • Ruler
  • Colored film filters
  • Excel sheet

Experiment process

  • We connect everything to the robot then we plug the USB cable between the robot and computer.
  • Then, we open the Labview program
  • This experiment is different from the other one because we did not need to type or calculate any thing before we pressed START.
  • While one of my teammate pressed START on the program, the other would hold a button on light source with a colored film filters inside.
  • After that, this teammate would shake it until the data on the program count to 30. While shaking, we had to count the amount of shake.
  • Every time we did it, we had to open then close the excel sheet. We had 5 times for this experiment.
  • For each time, we had to type the amount of shake and calculated the sum of voltage (30 numbers for each time).
  • Also, we had to calculate the voltage in square and we only took the voltage which is square from each time for the final result. For example, we have 30 numbers on the last time. We tried to calculate the square each of them. Finally, we plus all of those square number together to get the sum of (voltage)^2

  • Finally, we came up with this table and graph.

  • However, it is not similar to what our professor expect for the final result.

 

Conclusion

The result seems a little bit weird because there is negative and not as same as what professor expect for the final result. I think that it is because I was stop a few second while doing the shake, then the result is not correct at all. For the next time doing this kind of energy experiment, I think that we have to eat breakfast before coming to class to have full energy.

Tesla Coil

Background

Nikola Telsa was an Serbian American inventor and electrical engineer who used a coil to produce wireless energy in his innovative experiments such as electrical lighting, phosphorescence, or X-ray generation. Inventor Nikola Tesla was born in July of 1856 in in the village of Smiljan, Austrian Empire. He came to the United States in 1884 to work with Thomas Edison for the Continental Edison Company in France, designing and making improvements to electrical equipment. In 1886, Telsa opened his own company with the other two partners, Robert Lane and Benjamin Vail, and named for his company in Telsa’s name,  Tesla Electric Light & Manufacturing. In 1891, he invented “Telsa coil” which is an electrical resonant transformer circuit that still be used in radio technology today. He died on January 7, 1943 in New York. 

 

What is a “Telsa Coil”?

“Telsa coil” which is an electrical resonant transformer circuit. It was invented in 1891 which was before the conventional iron-core transformers. Telsa coil is set up with two part: primary coil and secondary coil. Those two coils and capacitors are connected by a gap of air. The spark gaps connect the coils to six pack capacitor and NST protection filter. From the filter, everything will connect to a Neon sign transformer.

How does it work?

  1. The transformer boosts the voltage 
  2. The power source is hooked up to the primary coil. The primary coil’s capacitor will soak up to charge to develop the wireless energy.
  3. The electric current will build up until the energy hit the the tipping point. 
  4. A hug voltage current will flow from the gap to the secondary coil. 
  5. The energy go back and forth between two point. On the secondary coil, there is a top-load which will shoot out the lightning when all the current is concentrated.

 

“Fix the World”

Fix the World S.A.R.L is an international business and humanitarian association which was established in 2012. Fix the World has released an energy generator which is inspired by by Tesla’s “Energy Generator” in 1894. They focus on any project dealing with energy access, economic hardship, and basic humanitarian aid. One of their project is Quantum Electric Generator (QEG) which uses the law of Tesla Coil to develop energy to make the light bulbs light. It is one example that people using Tesla Coil to produce energy today. The video below showing hos QED works and it surprising result. 

 

 

Conclusion

Even though Tesla was called “mad scientist”, we cannot reject that his idea about free energy is interesting and valuable. I hope that we can use this idea to solve the energy problems today. Fix the World is like a pioneer in this field by using a wonderful idea to solve electrical problems. Their effort will be accepted on someday .
