Patent number: 8709221Abstract: An embodiment of a system and method provides a current regulating device that controls or regulates the current provided to electrolysis chambers that produce hydrogen and oxygen gases. One embodiment of the current regulating device uses the temperature of the fluid in the electrolysis chambers to control the widths of the pulses delivered to the electrolysis chambers to regulate production. Another embodiment of the current regulating device regulates and limits the average current delivered to the electrolysis chambers by adjusting the pulse widths, according to the current demanded during each conduction pulse.Type: GrantFiled: February 24, 2011Date of Patent: April 29, 2014Inventor: Andrew L.

Publication number: 20140106007Abstract: The methods, systems, and apparatus disclosed herein employ natural, common salts, that are electrochemically activated (ECA) in an aqueous solution to result in an ECA product solution that is safe and non-toxic. Various implementations include a portable table top design having a portable receptacle that includes electrodes. The receptacle fits on a base which provides power for the electrochemical activation. Continuous flow designs receive input water, mix the water with reactants then pass the solution between electrodes to electrochemically activate the solution. Using a metal halide salt, such as NaCl with citric acid may produce a sanitizer or disinfectant. Using a metal carbonate salt, such as K2CO3, as the reactant may result in a cleaning or degreasing solution. Another implementation is that of an immersion wand that can be placed in a reservoir to produce the ECA product solution.Type: ApplicationFiled: October 16, 2013Publication date: April 17, 2014Applicant: GenEon Technologies LLCInventors: John P.
