You forgot how it was shown to not make anything near the amount of energy Stan claimed.That's incorrect. He was sued on the basis that he had promised investors that his car would be able to run using perpetual motion. After being analyzed, the car was shown to run using electrolysis. That is the point I was making, is that electrolysis as a means of creating HHO for fuel, is not a new idea and has been around for a long time.
in other words, he claimed it did something it didn't, and claimed results that he couldn't reproduce. That's not only a failure of scientific testing methods, it's outright fraud.
Newer cars such as the Japanese one also claim they're not using electrolysis. Once you say "no no, this is a different technology" you'd better be able to prove the technology you're claiming, or not ask people for money.
