Regardless of all the press related to hybrid cars, there are several areas where these cars create as much environmental concern as fossil-fuel vehicles.

Converting a gasoline engine to run on propane can reduce or entirely eliminate the need to purchase gasoline. The conversion works best on a car equipped with a carburetor, as the metering of the...

Hydrogen fuels offer some of the most efficient ways to "green up" cars in the future. But the approach also brings some challenges in terms of mass-market application and production.

Various companies, including BioPerformance, Fuel (or "Forever") Freedom International (FFI) and PowerPlus MPG either sell or recently sold pills and other forms of additives designed to increase...

A number of alternative fuels are available to the typical car owner, including ethanol, compressed natural gas, and hydrogen. Some alternative fuels require engine conversion.

Cars powered by hydrogen either have a H2ICE (hydrogen internal combustion engine) or make use of a hydrogen fuel cell. Fuel cell vehicles (FCVs) have an electric motor that runs on electricity...

Converting a diesel engine to run from waste cooking oil can reduce or almost eliminate your need to purchase petroleum based diesel fuel for your car or truck. Your engine will not need any...

Making your own biodiesel doesn't require you to harvest hard-to-find plants or act as a mad professor and scientifically create the fuel with expensive lab equipment. While the process of making...

Three common challenges I think Scientists all over the world face with managing oil, and natural gas, or coal would be: not having the since of urgency for renewable energy does not really set in...

Production of biodiesel is based on a process involving transesterification. The objective is to separate long chain fatty acid methyl ester (FAME) molecules from short chain glycerol molecules...

Hydrogen fuel cell cars use hydrogen that reacts with oxygen to produce electricity to power an electric engine. The cars have zero emissions when running, because the only byproducts of the...

Electric cars have been around for as long as gas-powered automobiles. During the late-1990s, automaker General Motors marketed the first modern electric car, known as the EV1. By the year 2000,...

Hydrogen fuel cells are a revolutionary technology that dates to the early 1800s. However, fuel cells have only been used in any serious capacity since the 1960s. Since then, fuel cells have been...

The more climate change becomes a reality for the global population, the more important it is to mitigate it in any way we can. One of the major contributors to climate change are motor vehicles....

Because of the fluctuating cost of gas, many people are weighing alternatives for powering vehicles. Some options are more viable than others, and you have to weigh the cost savings against the...

The need for an alternative to diesel fuel comes from factors like rising gas prices and helping the environment. Two popular alternatives are biodiesel and vegetable oil. This reduces or...

Ford Motor Company reports that 15 of its cars, trucks and SUVs can get 25 miles per gallon or better, based on EPA-estimated highway mpg and powertrain combinations. But Ford is making a...

High prices and contamination by petroleum mean it is time to find alternatives for heat and energy production. Converting vegetable oils into diesel fuel is a popular and inexpensive method of...

The first step in turning coal into energy is processing. Specialized silos in coal mills called "pulverizers" crush raw coal to a smaller consistency on par with sea salt. From there, the crushed...
