Your Protium company only guarantees a 10% increase in fuel economy using their hydrogen system. Consider the math... Assume I drive a vehicle that gets 25mpg, I drive 12,000 per year, and gas is $3.00 per gallon. That means I use $480 gallons of gas per year, costing $1,440.
Now using their system, I get 27.5 mpg. That means I now use 436 gallons per year costing $1309. Their system “saves” me $130 per year.
Unfortunately, their system costs $900 + labor. Assuming two hours at $60/hour, they total costs is $1,200. It takes 9.2 years to break even, or 12.7 years at a 5% cost of capital.
The good news is that if I install today, by 2020 I’ll break even. The bad news is, I’ll be driving a 13 year old POS.
your math is off slightly, but actually the results of most users is quite a bit higher than 10%. More like 25-50% and sometimes more. I found an even more affordable comapny here which has a wonderful hydrogen supplemental system that’s easy to install. Read some of the testimonials...very impressive and they can be verified.http://www.savefuel.ca/hydrogen/index.php?id=index
