Hi, This is my first post. I'm very interested in this subject having gone to the link on Shardlows
http://www.shardlowautogas.i8.com/ gas conversion page available on the LPG conversions on the FOG front page. On the top ads bar there are various companies trying to sell plans and books exactly as John (Smiffy) link. In fact nearly all the vendors webpages end up taking you to the same animated webpage
http://www.runyourcarwithwater.com/?hop=1goodchoic I can't help to be suspicious of this site as it is introduced but a girl called Rachel who looks remarkably similar to a girl called Kara.s who is endorsing their product.
I have a feeling it's a form of pyramid selling as they keep on telling you how once your satisfied you are free to sell the product on and use their marketing tools.
Not to be undeterred I continued looking and found information on a Stanley Meyer, inventor and developer of a dune buggy that ran on HHO exclusively. He died suddenly and his patents ran out in 2007, hence the sudden outpouring if information on this subject. I have found a site that has recorded experiments based on his invention
http://peswiki.com/index.php/OS:Water_Fuel_Cell and the results do appear to be promising. One experiment was producing .45lit/min from an input of 3amp/12volt pulsed.
As I'm off work sick I've got time to browse for this information and would consider doing an initial conversion like the one in John's link as it works with fuel injection but the full hho system would require a type of gas convertion and modifcation to engine and exhaust systems.
I'll keep you updated if I find anything further.
Andy
P.S. I hope the links work as I've not posted on here before.
