The fuel made of water is definitely not an oil fuel. So changing oil into water would not necessarily close the cycle. And changing the oil into water is very easy - just use the oil as a fuel and you get water and carbon dioxide (and some nasty side-products depend on the quality of oil).
Hi, I just registered only so I can complain about the Catbert changes you have introduced.
Just how many negative comments does it take to make you put this website back the way it was?
This is really a truly NEGATIVE HORRIBLE experience now.
It is Tediously Difficult to navigate, Slow to load, not at all fun like the original site.
The previous version was much faster to load too.
We ALL propose you should abandon trying to "PIMP UP" this site up and go back to basics
Please strip out ALL that boring Flash Nonsense and KISS (Keep It Simple Stupid)
By the way the GIF generator you are using produces terrible quantisation noise in between the main lines, it looks like you are using MS Paint? Yeugh! Pittooie!
