Water as gas? - Is this useful?

[angelsmile]

I am sorry, I just don't know where to post this...

I am planning to buy gadgets for what they called "water fuel" and have questions about this product. <potential spam removed>. Is this useful? Or does it worth the price? DO you know somebody who's using this, and was he satisfied? Just making sure if it is really useful before buying one.Thanks.
