HHO Generators versus Hydrogen Cars

Run your car on water HHO generators are often confused with hydrogen cars even though there is completely different technology at work. Sometimes people will confuse HHO generators with hydrogen cars intentionally, but most often is an educational issue instead.

HHO gas is a fuel additive for a gasoline or diesel vehicle. Water is electrolyzed into HHO gas, which is then fed into the vehicle's intake system and helps the gasoline or diesel fuel burn more cleanly, extending the mileage of the car, truck or other internal combustion engine.

Now, hydrogen cars, other the other hand use completely different technology. In fact, hydrogen cars themselves come in two different types including fuel cell vehicles and those that use internal combustion engines (ICE). In both of these types of hydrogen cars, water is not a primary source of fuel inside the vehicle nor is it a fuel additive.

Fuel cell cars, in general used compressed hydrogen gas, between 3,600 psi and 10,000 psi depending upon the manufacturer. Hydrogen gas and ambient air containing oxygen is fed to the fuel cell, which creates electricity, heat and a small amount of water as a byproduct. The electricity is used to drive the electric motors inside the vehicle.

Now, hydrogen cars that use internal combustion engines (ICE) also come in a couple of different varieties. Some cars such as the Mazda rotary are bi-fuel vehicles, using both compressed hydrogen gas and gasoline (which never mix) but can be powered by either fuel with the flip of a switch.

Another bi-fuel vehicle, the BMW Hydrogen 7 uses both liquid hydrogen and gasoline to power the vehicle, again with the flip of a switch (push of a button). The gasoline and hydrogen do not mix inside the engine. Now, there are other hydrogen ICE vehicle built by Ford or Quantum as retrofits that use only compressed H2 to power the vehicle.

So, yes, this is confusing and it is easy to see why many people talk about hydrogen cars and gasoline-powered cars with HHO generators interchangeably. But, the technology is not the same (not even close) and one should be wary of websites, journalists, advocates, scammers and others who confuse the issues with misinformation.
