    Analysis
In summary, the conversation discusses a dry cell built by the speaker and their desire to conduct various analyses, including conversion efficiency, stress analysis, fluid analysis, and electrical power analysis. They provide details about the structure and suggest keeping all variables open. The conversation also includes a link to uploaded pictures of the initial design and a discussion about the efficiency of the electrolysis project. The speaker expresses uncertainty about the treatment of HHO generators in the forum and explains the two opposing viewpoints on its effectiveness. They wish the person well with their project.

hello.. i have built a dry cell... i want to do the following analysis..please guide me with valuable suggestions...

1.conversion efficiency(chemical analysis)
2.stress analysis(it has nuts and bolts)
3.fluid analysis(KOH concentration-->viscosity,density,distill water...flowing down from a bubbler...head...etc etc...all which comes in mind)
4.electrical power analysis..efficiency..etc..


i have 7 SS 316 L plates...starting with 3 mm PVC plates..2.04 % KOH by weight...

structure details:

extreme end acrylic plates 1.5 cm thich each, 15 cm x 15 cm

12 bolts...0.5 cm dia and 6.5 cm length..each...pentagonal head...

etc..

i wud suggest keeeping all the variables involved as open...

thank u..

here is thee link to the uploaded pics of my initial design...

wotapeta,

I can't help with the chemical, stress or fluid, the electrical conversion efficiency is covered here:

Advanced Experimentation

Advanced students may want to study the efficiency of the electrolysis project. This can be done, under careful supervision (since you will be collecting hydrogen), in the following way:

1. First make the following measurements carefully and simultaneously:
* Collect the hydrogen produced with a test tube: The test tube should be initially filled with water (by submerging it) and positioned over the negative electrode, with the open end submerged and the closed end pointing upwards (such that the tube is completely filled with water at the start of the experiment). Run the experiment until the water level inside the test tube matches the water surface level. At this point the pressure of the hydrogen will equal ambient pressure. Stop the experiment when this level is reached.
* Measure the current I in amps: Do this by placing an ammeter in the electrolysis circuit - have someone read the meter during the experiment to get a good idea of the average current. Make sure you express the result in amps, which may require conversion from milliamps.
* Time the entire experiment with a stopwatch in seconds. (This may be a large number).
* Measure the ambient (room) temperature in Celsius degrees.
2. Calculate the volume of hydrogen produced at ambient pressure in cubic meters: Measure the dimensions of the test tube, and the length of the tube above water. Make sure you answer is expressed in cubic meters. For example, if you initially calculate the volume in cubic centimeters, divide your answer by 1 million.
3. Now calculate the theoretical (maximum) volume of the hydrogen produced, also in cubic meters, from the other data for the current and the time, using "Faraday's First Law":

Vtheoretical = (R I T t) / (F p z),

where R=8.314 Joule/(mol Kelvin), I = current in amps, T is the temperature in Kelvins (273 + Celsius temperature), t = time in seconds, F = Faraday's constant = 96485 Coulombs per mol, p = ambient pressure = about 1 x 105 pascals (one pascal = 1 Joule/meter3), z = number of "excess" electrons = 2 (for hydrogen, H2), 4 (if you're measuring oxygen production instead).
4. Finally, calculate the efficiency by comparing the volume produced to the theoretical maximum volume:

Efficiency (in %) = 100 x Vproduced / Vtheoretical .
5. Discuss the possible sources of inefficiencies/errors, such as
* Failure to capture all the hydrogen
* Energy lost to heat
* Various measurement errors

I am not sure how HHO generators are treated here in the PF. In general there are two camps: 1) Those who believe through some miracle a liter or two of Brown's Gas generated from a car's alternator improves gas milage 20% to 80% and could be made to run the car altogether without gasoline. 2) Those who debunk the idea as psuedo-science and point out that the energy gained from the Brown's gas is considerably less than the energy required to produce it.

Both sides are generally pretty insistent about being right. I have never seen a scientific proof or even explanation that gives any credence to the HHO concept, but there are tons of empirical testimonials, LOL. I won't argue it either way, but I find it unlikely you will get much help analyzing the various components of a system most scientific-minded people believe is a hoax, but perhaps I am wrong.

I wish you well with your project.

FAQ: Suggest analysis for HHO dry-cell

What is HHO dry-cell technology?

HHO dry-cell technology involves the use of an electrolytic cell to produce a mixture of hydrogen and oxygen gases, known as HHO gas, through the process of electrolysis. This gas can be used as a fuel source for various applications.

How does the HHO dry-cell work?

The HHO dry-cell consists of two electrodes, usually made of stainless steel, submerged in an electrolyte solution. When an electric current is passed through the solution, it breaks down the water molecules into hydrogen and oxygen gases, which are then collected and used as a fuel source.

What are the benefits of using HHO dry-cell technology?

HHO dry-cell technology offers several benefits, including increased fuel efficiency, reduced emissions, and cost savings on fuel. It can also be used in a variety of applications, such as powering vehicles, generating electricity, and welding.

Are there any potential risks associated with HHO dry-cell technology?

While HHO dry-cell technology is generally considered safe, there are some potential risks to be aware of. These include the risk of explosion or fire if the gas is not handled properly and the risk of corrosion to the electrodes if the electrolyte solution is not maintained at the correct pH level.

How can the effectiveness of an HHO dry-cell be analyzed?

The effectiveness of an HHO dry-cell can be analyzed through various methods, such as measuring the gas production rate, analyzing the gas composition, and conducting performance tests on the device. It is also important to ensure that the cell is properly installed and maintained for optimal performance.
