Hydrogen on Demand-the pitfalls

The HOD supplemental fuel system is a viable proposition, and relatively easy to achieve. Some persist with the argument that you can't get more out than you put in, as far as energy goes. They insist that the added load on an alternator to supply the power for electrolysis will outweigh the benefits of adding HHO gas to the combustion chamber. Many have proved this incorrect, by building simple DIY devices and achieving sizeable gains in fuel economy and performance.

There are also many who have not achieved the desired result. There are many factors that can affect the outcome. One major hurdle most amateur experimenters will encounter is the dreaded O2 sensor, part of a modern vehicles' anti-pollution control. This device maintains an air/fuel ratio of 14.7-1. Adding HHO gas increases the oxygen supply to the combustion chamber, and as a consequence the vehicles' computer will react by allowing more fuel through, thus decreasing economy! There is a quite simple fix to this problem, but if you are not mechanically minded, it may be a job for your mechanic or auto electrician.

The Water4Gas manual contains over 300 pages of useful information, as well as detailed instructions for anyone inclined to DIY. It also covers most of the common problems experimenters have been encountering, and provides a useful forum for user feedback. I don't feel that the design presented here is the best as far as gas production goes, but it is a good starting point for anybody wishing to explore the technology further.

With the price of gas continuing to escalate, what have you got to lose, apart from a few late nights tinkering in the back shed!
