I'll offer an anecdote. A neighbor of mine down the street (working as an engineer for GM at the time) was invited by Stan to help solve some of the pre-ignition issues with H2 in his buggy. He, along with his wife, went to Grove City and watched it run; his wife had her hand on the HHO generator and noticed that it never even got warm while producing enough gas to make the engine run.
That neighbor has offered the same assistance to me, should I ever get the Meyer system to work. These are folks that knew Stan and had every confidence that he could make it work as he intended, given enough time.
Maybe I'll get off my defeatist attitude and get back to work on this someday, and the sooner the better
Turtle, slow
