Science has known about the existence of hydrogen for about 250 years. People have been using hydrogen fuel as transportation since a few years after its discovery. America's hydrogen market...

Natural gas is considered an alternative fuel. Natural gas vehicles, which are more efficient than hybrid electric vehicles, work similarly to gas-powered vehicles and have spark ignited engines....

Build and use this hho generator to double your gas mileage. I hope you will be satisfied with this design, if you have suggestions please comment. I cannot be held responsible if any accident may...

The world seems to want to wain itself off dependence on fossil fuels. With the drastic rise in oil prices, consumers are met with a tough choice to adopt a more expensive, clean-burning car now,...

Hydrogen-hydroxide (also known as HHO) generators have been around for decades and can still be a viable option for many vehicles on the road today. HHO generators harness the powers of hydrogen...

The use of organic oil to make a usable diesel fuel is becoming more and more popular as the cost of regular diesel and gasoline soars higher. Using this method that anyone can learn to do at...

Propane gas makes for excellent juicy hamburgers when used in an outdoor grill. But that same propane also can be used to make a trip to the store to buy the groceries, too. Small-engine...

Solar-powered cars are powered by sunlight that is converted to electricity by the photovoltaic cells that line the car's exterior. They are limited to one or two passengers and must be very...

The Jerusalem artichoke, also known as a sunchoke, earth apple, topinambur or sun root, is a tuber of the sunflower family. It is indigenous to the eastern United States. It is found wild and is...

HHO refers to the process of splitting hydrogen atoms from water molecules in order to inject hydrogen fuel into the gas of automobiles to increase gas mileage. The method utilizes a device known...

Ethanol is one of the most common biofuels (liquid fuels made from plants) used worldwide. Ethanol can either be used as a stand-alone alternative to gasoline, or it can be blended with fossil...

As the search for alternative energy intensifies, there are numerous advantages to using hydrogen fuel cell electrical vehicles. Because they don't use gas and only emit vapor, they don't give off...
