2nd post by Steve Storey.  On June 2,  I met with customer and associate Computer Prof. Joseph Auciello, who is involved with using Hydrogen as a Supplmental Fuel, and we discussed "Hydrogen Cleaning" an engine that failed / would fail a "Smog Test".  Indications are that "Hydro Cleaning" does work.  But, we are not yet ready to offer it as a service, as we still want to test it on few more vehicles. The plan is to charge for the service with a "Money Back Guarantee" if it fails the SMOG TEST.   .. Stand by for                                                updates.   Regards.   Steve Storey.
