Water For Fuel E-book, Information Whose Time Has Come?

In light of current gas prices, the information on the following sites may offer a viable answer to big oil companies and help the environment as well. 

All three offer the same basic information based e-books.  The e-books show how the reader can build and install a hydrogen-on-demand system into any car using water as the source of hydrogen.  They differ in site design and the extras they offer with purchase.

Water4Gas:  This is the first site that I have seen that offers this type of e-book. The site has lots of testimonials and videos of news reports about the system and shows cars using the system.  There are some extra free e-books and a 7-day free e-mail course offered with purchase. Price: $97.00.

Run Your Car On Water:  This site is not as cluttered with testimonials as above.  It has some imbedded videos but does not include testimonials.  No extras are offered with purchase.  Price: $49.97.

Half Water Half Gas:  Like the one above Half Water Half Gas  is not cluttered with alot of testimonials.  It does have imbedded videos and few testimonials.  Several free e-books on car maintenance and repair with purchase.  Price: $67.00.

Is this a technology whose time has come?  What do you think?
