I would reeeaallllly like these products to work but unfortunately they probably don't.
The reasons they probably don't are as follows.
The hydrogen converter relies on the cars battery to supply current. As the battery drains and the voltage drops the car's voltage regulator will kick in extra coils in the car's alternator to create more current to charge the battery. This increases the altenators load on the car's engine.
Unfortunate the extra load on the engine will be far greater than the extra power created by the hydrogen. This is because of the following:
1. The electrically energy produced by the alterator is less than the energy drain on the engine.
2. Energy is again lost converting the electricity energy to chemical engery stored in the HHO.
3. Energy is again lost converting the chemical energy to mechanical energy when the Hydrogen is burnt.
As you can see there is a net energy loss at each stage and the system is draining energy from the car. Sad, but unfortunately true.
This can not work! because the law of conservation of energy states that the total amount of energy in any isolated system remains constant but cannot be recreated, although it may change forms, e.g. friction turns kinetic energy into thermal energy. In thermodynamics, the first law of thermodynamics is a statement of the conservation of energy for thermodynamic systems, and is the more encompassing version of the conservation of energy. In short, the law of conservation of energy states that energy can not be created or destroyed, it can only be changed from one form to another.
