Hi Tommy
I also have researched a few heated rod carburetor designs. Two of them were over20 years ago (before Pantones claims)  I was intrested in the claims of magnetic materials and heat being able to transmutate water (or bbq sauce) into fuel.  My tests with the free plans were identical to yours. NON PRODUCTIVE!
  GEET provoked me to investigate further, just to see if I could actually introduce a measureable amount of water into a gas engine, if so test the emissions and output.  My video showe's a very altered bubblier, although the geet is UN-altered. I was able to introduce approximately 60%gasoline to 40%  water.  It was easy to detect gasoline fumes, by smell , and carbon at about 5 to 10 feet with a detector. Longer run times were due to less fuel introduced via vapors. On a cold day I was able to recover the same amount of water from the exhaust that I started with, with this  I only suggest that I was removing most of the heat through the exhaust.  I received the usual hate mail, and of course have seen many on the yahoo group make the free plans and announce compleat success, just to see them later quietly leave the group.
  I invite you to watch my video on youtube lhester2003 search vortex heat exchanger.  Please take time to read the post from me on this video. I am not very computer savvy or I would provide a link like you did with your video.
Thanks
Leonard Hester

Hey Tommey U cold use your bubbler  to evaporate used oils that contains a lot of hydrocarbons to burnt in the engine. Just add some gasoline or a solvent and off  U go, saving money and environment.
