The NVI Hydrogen Generator is a device designed to save fuel, improve engine performance and provide a"green" alternative to conventional fuels like gasoline, ethanol and diesel. Also known as a Hydrogen Cell, the Generator provides better mileage which, in turn, saves gas or other fuel alternatives, while it improves engine efficiency and lengthens engine life. Anyone interested in saving money over the long haul, definitely needs the help a Hydrogen Generator can provide.Operating on the electricity provided by your vehicle's alternator, the unit actually provides "Brown's Gas," a combination of hydrogen, oxygen and water vapor, that is inhaled by an engine's intake system resulting in substantial cost and fuel savings through improved engine efficiency. Save gas cost, save mileage and provide "green fuel" to help save the environment. It's a "Win, Win" situation for everyone concerned.
Electrolysis of WaterOne important use of electrolysis is to produce hydrogen. The reaction that occurs is:
2H2O(aq) = 2H2(g) + O2(g)
This process is one way of shifting society toward using hydrogen as an energy carrier for powering internal combustion engines. Electrolysis of water can be achieved in a simple hands-on project, when electricity from a low-voltage DC power supply (e.g. 12 volt battery) is passed through a vessel of water.
In practice, some kind of electrolyte will need to be used. Electrolyte is a dilute mixture of minerals and water used to enhance the flow of electricity. Seawater is an ideal electrolyte but adequate substitutes are mineral water, spring water or even regular tap water.
The NVI Hydrogen Generator utilizes the electrolysis process, with certain patented (published 11/09/2009) modifications built in, to improve its efficency, durability and ease of operation. Gases are captured by the Generator, mixed with a filtered air flow, then directed to a vehicle's fuel intake system where they are combined with the vehicle's ordinary fuel/air mixture. The result is enhanced combustion, improved mileage and reduced greenhouse gas emissions. The reduction in emissions is caused when non-polluting hydrogen adds combustion energy, replacing some of the ordinary fuel needed to power the vehicle.
Electrolysis works when an electric current is applied, through an electrolytic solution, between a cathode (negative pole) and an anode (positive pole). During electrolysis, hydrogen gas will be seen to bubble up at the cathode, and oxygen will bubble at the anode. The two gases combined in a free state, constitute what is called "Brown's Gas" (see Note below) If, however, the wrong metal is utilized for the anode, oxygen will react with the anode instead of being released as a gas. For example, using iron electrodes in an electrolyte solution, will produce iron oxide at the anode, which will react to form iron hydroxide. When producing large quantites of hydrogen, this can significantly contaminate the electrolytic cell reducing its hydrogen output. This is why iron is not used by the NVI Hydrogen Generator.
The energy efficiency of water electrolysis varies widely. The efficiency is a measure of what fraction of electrical energy used actually produces hydrogen and oxygen. Some of the electrical energy is converted to heat and some reports quote efficiencies between 50-70%. This efficiency is based on the Lower Heating Value of Hydrogen...thermal energy released when hydrogen is combusted. This does not represent the total amount of energy within the gas since, hydrogen itself, releases a large amount of energy when it combines with oxygen to form water. Water formed during the combustion process will not contaminate or oxidize engine cylinder components since the heat of combustion reduces any water formed to steam that is expelled through the engine's exhaust valves. Likewise, the NVI Hydrogen Generator uses no lye or other chemical substances that could attack engine components.
The theoretical maximum efficiency of electrolysis can be as high as 80-94%. This maximum considers the total amount of energy absorbed by both the hydrogen and oxygen. These values only refer to the efficiency of converting electrical energy into chemical energy (combustible gasses). The energy lost in generating the electricity is not included. If, however, electrolysis is accomplished using an underutilized electrical source that already exists (the excess, unused capacity of an automobile alternator, for instance), high efficiency can be routinely achieved.

Note 2: Brown's Gas - A discovery made by Yull Brown of Australia, is actually produced by electrolysis and consists of mixed hydrogen and oxygen. This gaseous mixture is actually a better fuel than hydrogen alone. Reason - in many areas of the world, oxygen is in short supply in the air we breathe. Normally, oxygen comprises 21% of our air at sea level. If this percentage falls below 5%, serious consequences, even the death of many people, could occur. For instance, there have been reports of oxygen levels in the 6 to 7% percent range in Tokyo. The widespread use of Brown's gas to power industry and transportation, might actually improve oxygen levels in cities like Tokyo whereas, using hydrogen as a fuel by itself, would tend to leave low oxygen levels unchanged. A low oxygen level in the atmosphere is just another indicator of how serious our environmental problems have become and an excellent reason to convert our civilization to a Brown's gas-fueled future.
