No the videos are not faked, but your not seeing everything. Stan had stuff he would not allow anyone to video or photo. Also, there are all sorts of people in the videos, (Not all of them are dead.) Nobody has questioned them which I find odd. I'm not there so I cant, But I'm sure someone isn't sharing everything.
Stan also had what you called a water splitter just before the plug, Nobody has questioned that either. It is shown in 1 video online today.
The problem with not using additives, It does not bring the needed even burn rate. No additives brings a burn rate that is faster and cleaner and more volatile. Hydroxide solutions slow the rate and add too causing engines to run. A engine may run on 10 liters of hho that derived from an additive environment but 10 liters of hho from a clean environment will not match up or run the engine as the burn rate proves to fast and clean. Additives is a quick FIX for someone that does not know how to alter the burn rate of the pure clean gas. I'm sure the altered gas would be much better than using additives because you would have control over how you would want to make that mix, and I'm sure they mix would go beyound Koh etc,,. HHO as it sits as we make it clean, it is too clean and it is too volatile. it is too pressed together and it is NOT a synthetic gas as stan was using as pointed out in the patent in my pdf! CA---
