A booming segment of the Perpetual Motion Machine industry is capitalizing on the hype over the "Hydrogen Economy" with claims to produce Hydrogen for impossibly low cost.

Earlier Xogen Publication of ARC Report

Longtime Xogen watcher vcrepair found this older publication of the ARC report that contains the details that explain how the ARC mistakenly found a factor of 8 difference the ARC found between standard electrolysis and the Xogen process for the H2 produced per unit charge. The report can also be found in the SEDAR archives.

Summary of ARC test results and Company comment
April 6, 2001

Following is a summary of some of Alberta Research Council's test results. ARC was not required to conduct an economic assessment of the process. Under the terms of agreements between Tathacus Resources and Xogen Power, certain of the data will remain confidential for proprietary and competitive reasons. A complete copy of the ARC report on the tests has been filed with the Canadian Venture Exchange on a confidential basis.

Summary of ARC test results:
  • The Process involves the passage of electrical current through water for the generation of hydrogen gas and oxygen gas mixture.

  • A single waveform generator was used to operate a number of cells simultaneously.

  • No mechanically moving parts were apparent in the four generator systems which were examined and tested.

  • The feedstock water for the tests of the Process was taken from a municipal water supply line. No additives to the water are employed in the Process.

  • The gas production appears to be controllable on demand.

  • Gas samples collected and analyzed were found to contain hydrogen and oxygen gas in a ratio approaching a value of 2:1.

  • The Process produced a mixture of oxygen and hydrogen gases without recombination to at least 50 psi. (ARC did not test beyond 50 psi.)

  • The pressurization increased in a linear manner over time (during the
    short duration test), as illustrated in the graph in the following URL.

    (Company note: The data points were derived from an early prototype
    generator designed for research purposes only and not optimal gas
    production)
  • There was no heat sinking or cooling of the water incorporated in the test apparatus.

  • Water temperatures increased from 13 degrees Celsius to 30 degrees Celsius during the test. Temperature increase in the water of the Single Cell Modular Generator was observed to be 0.0013 degrees centigrade/minute/watt of battery input power.

  • Chemical analysis was conducted on the water by an independent laboratory before and after testing. The elements iron and manganese had increased as follows:

    Both iron and manganese are components of stainless steel, suggesting
    that the source of the increased iron and manganese content may be the
    stainless steel plates which form the cells.

    Tathacus comment on select ARC results:
    Prototype testing
    Four prototypes were tested by the ARC. They can be described as follows:
  • 1. Sealed Horizontal Generator - A sealed vessel containing a
    single cell comprised of stainless steel plates connected to a 12 volt DC
    power supply, a driver and a single electronic digital waveform
    generator. The total volume of the vessel with the cell in place was 5.35L.

  • 2. Split System Generator - A split generating system comprised of
    two sets of four cells contained in 8 open trays, where each tray contained 5 litres of City of Calgary tap water. Each set of four cells was connected to separate 24 volt DC supplies but the two sets were both connected to a single electronic digital waveform generator. Emphasis added. Bingo.

  • 3. Vertical Multiple Cell Generator - A multi-cell sealed vessel containing six vertically aligned cells all connected to a single 24 volt DC power supply, two electronic drivers and a single electronic digital waveform generator.

  • 4. Single Cell Modular Generator - A modular design vessel containing a single horizontal cell measuring approximately 15 cm x 25 cm x 8 cm. The vessel was made from 18 mm thick acrylic material with a top cover of 9.5 mm thick aluminum. The cover allowed for the connection of a thermocouple to monitor water temperature. The vessel contained a single cell connected to a 24 volt DC power supply, a single driver and a single electronic digital waveform generator. The single cell within its own vessel was intended by Xogen to function as the basic building block of its modular, scaleable system.


  • Xogen confirmed to Tathacus that the prototypes supplied for testing deliberately did not incorporate any form of heat sinking of the water. This was necessary to calculate the Process heat gain in order to engineer the cooling requirements necessary for commercial applications. Similarly, the tested prototypes included no filtration equipment to ensure accurate measurement of all properties of the Xogen process.

    Comment on gas analysis
    Xogen has advised Tathacus that conventional electrical methods of hydrogen production typically have wet gas output that requires drying prior to most commercial uses. Due to the lower operating temperatures possible with the Xogen process, a dry oxygen-hydrogen gas can be produced that is suitable for combustion purposes without further processing. Given the two-thirds hydrogen, one-third oxygen composition of the gas, Xogen has a nearly perfect stoichiometric mixture for combustion.

    Comment on iron and manganese findings
    Xogen has confirmed that plate and connector material optimization has yet to be undertaken. (Re-specification of plate material or design adjustments may occur in future as a result of optimization studies.) Further, Xogen advised the Company that none of the test apparatus has been the subject of optimization engineering, this being the matter of future development intended to be conducted largely in the context of technical co-venture or licensing agreements with appropriate, qualified parties in each field of potential commercial application.

    We can see above how the factor of 8 error was made. If the volume results that purport to show that Xogen's process are not electrolysis are based on the 8 cell "split system generator" or some other configuration where 8 cells are in series then the whole current is passing through each cell.
