Joule, a unit of energy or work in the metric system of measurement. By definition, one joule is the work done when a force of one newton is exerted over a distance of one meter. (A newton is the force necessary to give a mass of one kilogram an acceleration of one meter per second per second.) The joule is an absolute unit—that is, it is based on mass rather than weight and hence is independent of the force of gravity. Another, less commonly used metric unit of energy or work is the erg. One joule equals 10,000,000 ergs. In the traditional English system of measurement, the foot-poundal is used in place of the joule. A foot-poundal is equal to approximately 1/25 of a joule.
Imagine how convenient it would be if two-thirds of the Earth's surface was covered with a readily available, nonpolluting fuel source. With the discoveries being made in regards to salt water fuel, you may not have to imagine much longer. In 2003, John Kanzius serendipitously discovered a way to burn salt water. How would salt water fuel impact the world?
If you've ever walked the New York City streets in July, you've experienced the misery of this phenomenon. Why do cities heat up like furnaces while surrounding rural areas remain cooler?
