Pressure Testing

At the conclusion of the endurance testing we conducted  a pressure test on the cell used.

The aim of this test was two fold.

  1. To find out at what pressure the HOH gas collapses back on itself
  2. Establish the burst pressure of the HOH Cell

We had hoped that the cell would endure for the first test, so the second could be conducted.

The following video footage was recoded with narration:

HOH Generation 3

The Generation 3 Cell

Bringing together lessons learnt from previous designs.

  1. Circular Cells have a more consistent distribution of the energy across the cells
  2. Electrolyte reservoir positioning and proportions
  3. Construction Methods and Materials
  4. Plate surface area in relation to continuous gas output (current density) 
  5. Testing of various pneumatic fittings

Following are some detailed assembly images showing each component of the cell and their construction order along with some video footage of the system in operation.this

HOH Generation 2

e2_9The second generation of the HOH Cell was inspired by the teachings of Les Banki from the Climate Technologies Solutions Association.

I was invited by this group to share my media experience with ACA and found a wealth of knowledge and dedicated team of people working hard on HOH Systems.

I continued to attend these monthly meetings, listen, learn and understand the difficulties that were being confronted by this group.

After one of these meetings (late in the evening) I sat down with pencil and paper and continued to repeat to myself.

This is a gas intended for us through nature and nature has an innate ability to keep things simple.

The outcome from this thinking was the HOH G2. – A recirculated series cell.

This system was the first real insight in to the efficiency of the series cell design and was a departure and break-through from traditional series cell designs.

Here is a collection of images and drawings based on this design.

HOH Generation 1

01_unitThis journey of research and discovery began with a simple questions:

“Why aren’t these system readily available?”

Like many others I found some information on the internet on how to build a hydro-booster for my car.

The system was based on the details found here: http://waterpoweredcar.com/images/hydrobooster.pdf

Electrolyte Reservoirs

Introduction:

er_dr_combos

Electrolyte reservoirs can be made in a large variety of shapes and sizes.

If thought and consideration is given to the design then electrolyte reservoirs can be made to fit almost any situation or requirements.

The basic requirement for a combined electrolyte reservoir and bubbler is to allow fluid to flow to your cell and allow the gas to return.

It is ideal for the fluid and gas to “bubble” through itself, as this helps to separate the two and provides a safety barrier to your cell in the event of flashback.

The larger the header tank the greater the need for a primary safety barrier in the form of an arrestor as the increased volume increases the need for material resistance to shock.

As a start we are going to look at a basic schematic so the principles of how this functions can be understood. I will also highlight some of the many combinations.

After this we can explore some of the construction options, including no special machining and another version which requires some special machining.

Option 1:

Vertical mounted, Horizontal alignment

In this first diagram is what we have found to be ideal regarding positive fluid and gas flow between the cell and the electrolyte reservoir.

You will notice that the blue line represent the gas and fluid flow arrangement, with fluid being gravity feed to the bottom of the cell and gas and fluid exiting through the top of the cell.

The HOH gas then bubbles through the entire fluid, indicated in yellow, then exits through the top, indicated in green.

As a configuration this is ideal for the following reasons:

  • Maximises gas and fluid separation
  • Utilises all fluid contained in the reservoir
  • Minimises “slosh” through the exit port

Contraindications: (negatives)

  • Occupies more space
  • More complicated machining required
