Has anyone heard about this technology?  Apparently you have a container with distilled water and some baking soda in it.  It has steel coils or plates in it which is connected to the battery.  It is suppose to produce hydrogen which is mixed with your gas or diesel and helps improve your gas milage.  My brother told me about this the other day.  He is having it installed into his F-250 (5.4 L engine).  His friend has it installed into his Dodge that has a cummins in it and says that his MPG has improved to almost 30 mpg.  Has anyone else heard or used this application in their truck/suv?  Or is this just smoking mirrors?  If it really works I would like to install it into my F-350.  

I have a friend who is going to try something like this, although I'm not sure exactly what he is planning.  I will try to put an update here when I find out how it is working.
