Hi Ash,

I have already looked into the Boyce 101 plate system, and have a copy of the d9.pdf document which provides full construction details. I downloaded that from the Peswiki site at and I know you also have that file at Panacea. At this point I'm not sure what I will actually end up deciding upon for my Prius conversion. Perhaps it will be a combination of things. There is absolutely no room in the engine compartment for the addition of any device larger than a harmonica, so if I use something like the Boyce system then it has to go inside the cargo area beneath the hatchback door. That worries me somewhat, because of the long routing of the HHO supply tube to the engine, which must either pass directly through the passenger area, or directly below it. Also, the only separation between the electrolyzer and the passenger area would be the back seat. And as I pointed out in my first post on this thread, I would still be buying gas. The Boyce electrolyzer is not a total solution. If I add a device of any size to my cargo area, then I would prefer to add something that is a battery charging device rather than a fuel device. And to that end I am open to all suggestions. If I can't come up with a suitable battery charging option for my 202 volt NiMh battery, then I will probably opt for using metal hydride hydrogen storage tanks that I can recharge at home. United Nuclear United Nuclear - Hydrogen Fuel Systems uses a set of 4 small tanks in the cargo area of their 350 Corvette to achieve a range of 350 miles on hydrogen only. They have developed a new "Smart Tank" system which should increase the Corvette's range to 450 miles. So just think of the range that my fuel thrifty Prius could achieve in comparison! I should be able to go 1,000 miles or more on 4 of the small tanks while another set is being recharged, and never buy gasoline again. This type of conversion would cost about half as much as the HyMotion LI battery pack addition mentioned in my last post. And if I use a Bedini machine and solar panels to power the Hydrogen generator then my refills will have zero cost beyond the initial investment. I am still open to any battery charging ideas, though, so will gladly consider any and all suggestions along those lines of thought.

Thanks, Ash, and best regards to all,

Rick
