Abstract

I would like to explore how Euglenas would behave in the electrostatic water. The electricity would be created by Kelvin generator which converts falling water to electrostatic charge and using the electric wires to conduct electricity. Then we could test its functionality and how much current electricity would be created. Then we could try to redirect the electrostatic field into a DC current and then let it flow in the water and see how Euglenas behave. Based on the experiments we could explore how Euglenas would behave in different intensity of electricity and Euglenas could stand how much electricity in water.

Preparing materials

• 
• 
• 
• 
• 

Materials List Two Coca-Cola drink bottles；Two Paper Milk Boxes；Two foil paper Bowls ; One big Plastic Plates; Wires

Functions of each parts:

Two Coca-Cola drink bottles：I chose two Coca-Cola drink bottles as the materials of metal rings that is the most important part in the system of Kelvin Generator. In order to improve efficiency and save more time to test the system of Kelvin generator, I chose Coca-Cola drink bottles as the materials to make metal rings，because I thought they were made by metal and they were more easily carved up by cutter comparing with other metal cans.

Two Paper Milk Boxes： Considering the volume of insulated containers, I chose two paper milk boxes as the water tank, because the surface material of them inside were plastic film which were insulator and solider than paper, if we wanted to contain more water and easy to carry, that is a good choose I though at that time.

Two foil paper Bowls: I chose the foil paper Bowls as the container of water flow in this system, because they could conduct electricity and light quality, the most important things is that they were just in my kitchen. So I could use them as soon as possible to test the system.

Kelvin generator 1

• 

Introduction This is my first plan of Kelvin generator. I used two isolated paper boxes to contain water separately, then water could flow out from the tiny hole in the bottom of each paper box and passed through the metal ring. Then the foil paper bowls could contain the vertically falling water separately. Then the last thing was to connected all these wires and waited for current generation.

Analysis This is my first time to build the Kelvin generator, so I wanted to use these materials to test the system and produced electricity for further study. I prepared all these materials to build the first Kelvin generator, unfortunately it was not simply as it looks like.

Test the model

This was the best test until now, because the volume of current got to 2V and the monitor was shaking from up and down. Unfortunately it worked just once time. We were really confused about why it worked well just for one time. This was really weird.

Then we searched the videos about kelvin generator and wanted to find the reasons or just get some valuable reference about the model. Then we saw the simple structure of kelvin generator and wanted to use this construction to make a new one. Just like this picture.

Then I did not hesitate to buy iron hangers from dry cleaning shop.

Then Miga help me modify the shape of the iron hanger.

Unfortunately，it also did not work even though they were almost the same style of kelvin generator comparing with that one on Youtobe.

This kelvin generator worked but not performed very well. The volume of current only got to the half past one. I was a little bit upset, so I did not take picture to record the outcome of the figure of current.

Today I went to the toom which is the biggest materials store in Weimar. I looked each kind of materials carefully and took all the reference pictures about kelvin generator, but unfortunately most kinds of materials could not be find, for example the tiny plastic or metal water-taps, they only have the bigger metal water-taps which are so heavy and big. I could not find the proper size of water controller and the materials they used in tutorials on Youtobe. For example the plastic pipes in this picture.

• 

In fact, they were so common. But the most important thing is that I could not find these common materials to do this experiment. It heard just like a joke, but it is exactly the truth. Life was so hard.

Make the final model.

I stayed in the wood workshop for the whole day to use the machine to cut wood and made holes in plastic pipe. I did not have enough strength, so I took a longer time to fixed the wood board.

The last experiment

I tried the second time that made the device more higher
