Yet a signal cable that runs beneath the ocean experiences capacitance, acting as a capacitor "plate" surrounded by another capacitor "plate".
Why would resistance matter for the sea water if we are accumulating charge and not current?
What about bottle capacitors that were used in Tesla era...
One plate is a 1m^2 metal plate, another "plate" is sea water around the first plate.
Sea water is conductive.
This is the whole point.
Some layer of plastic between salty water and metal acts as a dielectric.
For now, I would assume that the dielectric is 0.2mm polyethylene.
Thank you.
I am not trying to build a power plant.
I just want to understand the order of magnitude of the output.
So I can compare it to mechanical harvesters of sea wave energy.
Can we leave out the algae and storms and all the other environmental factors and imagine an ideal setting:
Ideal...
Thank you.
It is too early for engineering advice.
Please don't give me any engineering advice. I am not going to tell you all the details of the project.
Please instead tell me how much power I can get from 1m^2 of electrode, hidden behind dielectric plastic.
Maybe I only need to harvest enough to top off a very small battery on an all-plastic research buoy that floats in the middle of the ocean and this system suits my requirements in many ways?
Also, I understand that if I use two sets of sealed electrodes, that they will need to be submerged at...
Why did it take me so much energy to explain to you that salt water is not a dielectric in this design?
That water is another "half" of the capacitor.
I have a theoretical, abstract 1m^2 sheet of aluminum of negligible thickness.
It is sandwiched between two layers of 0.2mm of polyethylene...
What irreality? I am not suggesting to build a commercial powerplant. I want to know how it would compare to other technology available.
I asked you how much power can such capacitor device produce from each change of "wet" to "dry" or full to empty.
What don't I understand? It took me several...
Imagine that there is a dielectric and one metal "half" of the capacitor, yet water flows instead of the other half of the capacitor plates. How does it not penetrate electrostatically?
Water meshed in with metal, separated by a dielectric vs metal meshed in with metal, separated by a...
Why wouldn't middle plates add to capacitance? Look at ordinary capacitor. Imagine that plates on one side are replaced by water.
Yes, I am talking about water and air alternating.
How do I calculate the amount energy a changing capacitor like this can produce?
There is already an insulator - all metal is covered with a layer of plastic.
Sea water and metal are separated.
How much power can I produce from 1 m^2 of this capacitor plate, insulated in plastic, surrounded by sea water that moves up and down? This means all submerged or all exposed. Salt...
I want sea water to act as a "liquid capacitor plate" that is also connected to the "ground".
The plastic will act as a dielectric.
How much power would this produce?
Thank you for answering some of my questions.
I used two half-capacitors because I didn't want any metal contacting water.
How does this factor of 80 relate to the amount of plastic and aluminum that would be required to produce one kilowatt of power from oscillations of the ocean?
This...
I understand that the capacitor will push back on the water trying to move through the plates, as the charge is building up.
I want to know if the movement of the water will cause any alternating/back and forth currents to flow between the two halves of the system. Every time the water level...
