Hydrogen Fuel Alternative is a great alternative for combustion vehicles, 100% hydrogen conversion kits are currently being developed to adapt to the 
average vehicle. Hydrogen burns so clean, efficient, and hot enough, to incinerate the smog air intake, it literally cleans smoggy air (engines that clean air), making the steam (H2O) exhaust, cleaner than what you started with. This is highly important in smoggy areas, cities and environment in reducing the greenhouse gases. Properly adjusted motor, will run cooler at modestly higher power. Safer than gasoline.
Is there a Tax Credit or Deductible for this technology?
Adding 5% Hydrogen Kit
Can greatly increase you fuel mileage to an average vehicle 30% with the least 
amount of cost, modification, user & maintenance friendly. Here’s an example of a Dry Cell Electrolyzer
(Brown’s Gas), water passes through the electro plates instead of the plates being submerged.
I personally prefer a near Plug-N-Play concept, this being easier to work with as well as producing greater amounts of Hydrogen by design, as much as 1.5 to 6 liters per minute. Compared to other units on the market, that I have tried & not that easy to work with nor a good producer, in my opinion. This design, quality of material & near Plug-N-Play circuit is the best that I have found for the budget.
3 Basic Steps
Step 1) Purchase Hydrogen Electrolyzer >>>
and Install (Basic Diagram) >>>
Step 2) Install PWM (Pulse Width Modulator) for added efficiency & add electrolyte water (Details)>>>
Step 3) Modify O2 Sensor & MAP/MAF Sensor (Details) >>>
Carbureted vehicles need a slightly lean adjustment & Adjust (Retard) Timing by 2 degrees closer to BTC (Details) >>>
Where’s the savings?
My friend John has a Chevy truck V8, he averages 300 miles per week, 14 miles per gal (MPG). 300 miles/14 mpg = 21.5 gal of fuel used for that week.
He then added a 21 plate Dry Cell kit, EFIE circuit & adjusted the timing.
He now gets well over 20 mpg, we’ll stick to 20 for example. 300 miles/20 mpg=15 gal of fuel used for that week.
Six gal of savings per week x 4 weeks = 24 gal savings for the month. 24 x 12 months= 288 savings x $2 per gal average= $576 savings for the year.
He can then claim his IRS Tax write off of $300 for New Tech. Upgrade = $875 Savings! For the year!
