Can Supplemental Hydrogen Reduce Emissions, Save Fuel?

Detroit +Scientists: Supplemental Hydrogen has the potential to improve Fuel Efficiency, reduce Harmful Emissions, allow Leaner Operation of Internal Combustion Engines

What is a "Water Car" anyhow? To tell you the truth, after 3 years in this business I'm not sure. Rumors say that there are water cars running on water only. I've seen movies of a Japanese company claiming to have a water car. Anyway, I haven't seen any that I can touch and test-drive, and just for clarification I do not call vehicles "water cars" but something like "water assisted vehicle", or "hydrogen assisted vehicle", or "water hybrid," or something like that. When you say "water car" people's imagination starts to run wild. 
 
Anyway, blueprints exist for famous designs claimed to be "water cars" or at least something in that direction. I've seen "water-car plans" sold on eBay and other

websites for $20 up to $189 each. Don't pay $100's for these "watercar" plans because you will receive this rare compilation of TWELVE plans for famous "water cars".

These documents are not an advertisement to buy stuff. The information is ALL THERE, from text and graphs to mechanical diagrams and electronic schematics. You will find that these plans are actually a package of very rare data and instructions, jam-packed with rare information (nearly 300 documents). Here's a sneak peek into WATERCAR PLAN #10

I do not have the funds to prove the validity of these plans. I have NOT written them either. Yet I feel that it is important to keep these ideas alive. Again, the term "water car" is very vague and even though some people claim they have seen cars running on water alone, I haven't seen one myself. This "water car" collection is provided to you for entertainment purposes only - don't go ahead and build a business philosophy around it because it is nothing but free but hard-to-find information from the Internet - beautifully organized and given to you free with your order - but that's about it.

You will receive immediate access to "water-car" designs by the following inventors:

1. Stan Meyer (Stanley Meyer)
2. HydroStar (or "Hydro-Star", and its newer version "HydroGen" or "Hydro-Gen") - you will get both versions! Do not pay $49 elsewhere just to get the fuzzy older version!!! I won't mention names, but if you've purchased these plans elsewhere then you've been ripped off - take your money back and get both Hydro-Star and Hydro-Gen here free with your order!
3. "Joe" (Joe Cell) the mysterious inventor from Australia, as documented by Alex Schiffer and others
4. The famous GEET by Paul Pantone, reported to me as good for stationary fixed-RPM engines
5. Rudolph W. Gunnerman
6. Carl Cella
7. Juan Carlos Aguero
8. Archie Blue
9. "Smack" Booster
   
10. The Australian "Nitro Cell" or "D18" by an unknown inventor
11. The famous Camaro design by an auto mechanic who identified himself only as "S1R9A9M9"
12. "Watercar" plans published by Drunvalo Melchizedek from Spirit Of Ma'at.
