Does HHO Generator really work?

There are a lot videos and manuals on the web, where we can learn how HHO generators contribute to vehicle power. Weather as somebody intends to purchase professional HHO generator or to make one at home, he has to investigate for all advantages and disadvantages.
Does HHO Generator work on vehicle? I believe it works. Does it efficiently work? I’m not sure. However, HHO generator kit installed on vehicles doesn’t meet basic energy balance. Einstein said once: If the practice doesn’t meet the theory, change the practice. This is the top energy quote over the years, but our time people claim: yes, it efficiently works !

How does HHO generator work?

The HHO generators are the devices those are used in both the automotive and welding industries. The technology is based on process of electrolysis of water to convert it to its gaseous state H-H-O (hydrogen-hydrogen-oxygen). This is low efficient process with about 35% energy wasting. On other hand, HHO gas (hydroxy or oxyhydrogen) is a powerful welding gas, which is wide used in the industry. Oxyhydrogen gas produced from HHO generators can improve combustion into engines also. The hydrogen and oxygen gas mixture 2:1 helps the gasoline or diesel fuel burn more cleanly inside the cylinders that contribute to fewer emissions and increased gas mileage. It is doing more by gasoline/ diesel oxygenation then hydrogen combustion. Hydrogen in gaseous state has lower energy content then each gasoline or diesel, thus can’t improve power of the vehicle. Possible improvement can be high temperature of hydrogen combustion chemical reaction between gaseous hydrogen and compounds of standard fuel that improve combustion characteristics.
I don’t believe, although it may work somehow …

Water Electrolysis inside HHO Generator - Hydrogen on Demand System

HHO (hydrogen) Generator is not Fuel Cell that is in using to run hybrid cars as an electrochemical conversion device. Fuel Cell produces electricity from fuel (on the anode side) and an oxidant (on the cathode side), which react in the presence of an electrolyte.
HHO Generator Hydrogen is based on Demand System i.e. water electrolysis as well as hydrogen production during the driving. An energy source for water electrolysis is used 12V electric current produced by the alternator. Water is being decomposed into oxygen and hydrogen due when electricity is being passed through. An electrical source is connected to two electrodes, which are placed in the water. Hydrogen will be separated at the cathode – negatively charged electrode and oxygen will appear at the anode – the positively charged side. It is the basic of technology. There are many improvements, such as electro electrocatalysts adding or pressure oscillating to regulate boiling point of water. These depend of HHO Generator type and construction.

Energy and Material Balance of a HHO gas generator

In order to effective, the HHO generators have to produce enough hydrogen to replace 2% - 5% of the flow. Energy material balance and show that is very complicate or even not possible.

H2O = H2 + ½ O2 – 237 kJ/mole

Decomposition of a water molecule into gaseous hydrogen and oxygen require input 237 kJ/mole. Standard engines need 0.2kg – 0.5kg of gaseous hydrogen per hour. Take in consider that 1 mole weight of a hydrogen molecule mole is slightly more then 2g, HHO generator needs 47.4MJ - 59.3MJ in order to produce enough amount of hydrogen. Energy will not be taken from ‘nothing’. It must be provided from gasoline combustion. Energy content of gasoline is about 31 MJ/lit (depend of blend). It means that HHO generator consume about 1.5lit - 1.9lit gasoline an hour. Water electrolysis efficiency can be maximum 67% which increase, which additionally increase HHO generator consumption to 1.85 lit – 2.3 lit an hour. If we convert it in imperial unit: extra consumption in average 0.5 – 0.6 gallon per hour. If we take that average consumption is about 2 -2.5 gal/ hour (60 miles driving) HHO generator would finally increase fuel economy by 20 - 25%. Consuming more fuel to have the same mileage is not an increase in efficiency. All the facts are assuming prevention water boiling during electrolyses.
Another task is electric system. For a 12 Volt electrical system, this requires about 420 Amps. The wire need to be as thick as building armature to be able to conduct this electricity. Standard wires in vehicle’s electric systems are 5 – 10 thinner. The HHO Generator is an excellent as a device for production welding gas.

However, it may works efficiently

Despite these facts, many people claim they got increased fuel economy and power of their own car. However, the market of HHO Generator is developing more then ever and thousands devices have been sold every year. There are developed many HHO Generator for car types and constructions. This Hydrogen on Demand System may not be a scam, due to producers warranty and money back system. Don't be too quick to make your mind up advantage or disadvantage about the issue. Convince yourself first.
