The secret to all of these gas saving systems is in burning hydrogen.  Hydrogen can easily be generated by passing an electrical current through water in the presencs of a catalyst. The hydrogen is collected and fed into the air intake of an engine.  Hydrogen releases tremendous amounts of energy when it burns.  This can result in as much as a 60% saving on your gasoline bill.  It is completely safe for your engine, and can take as little as an hour to install.  I have reviewed the top four sources of information on getting the job done.  I have installed the equipment on my 1999 Ford F150.  I know my gas gauge isn't going down nearly as fast but I want to do a real test on the highway.  I'm really excited about stretching the fuel in my gas tank.  I should have some real numbers in a few days. I purchased the information offered by these four sites and reviewed all of it before making the installation on my pick-up.  Some of the information packages were easier to work with than others.  After rounding up all the components my installation took an hour and ten minutes.  Not too bad for a guy that can barely change his own oil.    Water 4 Gas is my number one pick.  It's the package I personally chose as the very best after researching all the alternatives.  The instructions are laid out logically and are extremely easy to read and comprehend.  They even give you some ideas how to start a small business around this money saving idea.  The materials list and detailed explanation make this a no-brainer when it comes to saving real money on your gasoline expenses.       Half Water Half Gas  was nearly the winner of this survey.  Its somewhat cheaper but the instructions and diagrams are not as easy to work with.  But for those that have a natural mechanical bent this will be no problem.  Still a good value.     Fuel Trips covers a little more information than the other two being reviewed here.  Not only does it cover the basics of hydrogen fuel conversion, it gets into bio fuel production for those of you with diesel engines.  Along with a comprehensive discussion on a large number of ways to reduce your fuel consumption it can be a great starting point for understanding of fuel economy.     Run Your Car On Water is a good package for those with a little more mechanical ability than the average person.  The explanations are a little lacking and the diagrams are a little unclear in a few areas.  It is however cheaper and for those that can fill in a few gaps it can be the best choice.       Check out this video of a guy that hooked up a similar hydrogen assist unit to his pick-up truck     © Copyright 2008 ExlxE.com
