A heat engine is a system that converts heat to usable energy, particularly mechanical energy, which can then be used to do mechanical work. [1] [2] While originally conceived in the context of mechanical energy, the concept of the heat engine has been applied to various other kinds of energy, particularly electrical, since at least the late 19th century.
Oahspe devotes an entire interior book to the subject, called the Book of Cosmogony and Prophecy, but a general overview can be read in the Book of Jehovih. Also, many examples and edifications are sprinkled throughout Oahspe. Other related subjects include physics and an integrating treatment of gravity, light, electricity, magnetism, heat ...
The book is considered the founding work of thermodynamics. [2]: viii It contains the preliminary outline of the second law of thermodynamics.Carnot stated that motive power is due to the fall of caloric (chute de calorique) from a hot to a cold body, which he analogized to the work done by a water wheel due to a waterfall (chute d'eau).
For the three examples given above: 1) Heat can be transferred from a region of lower temperature to a higher temperature in a refrigerator or in a heat pump. These machines must provide sufficient work to the system. 2) Thermal energy can be converted to mechanical work in a heat engine, if sufficient heat is also expelled to the surroundings.

The Catholic Bible contains 73 books; the additional seven books are called the Apocrypha and are considered canonical by the Catholic Church, but not by other Christians. When citing the Latin Vulgate , chapter and verse are separated with a comma, for example "Ioannem 3,16"; in English Bibles chapter and verse are separated with a colon, for ...
He also wrote a book titled Science and the Bible and his faith has been described as "both orthodox and intense". [81] James Prescott Joule (1818–1889): studied the nature of heat, and discovered its relationship to mechanical work. This led to the law of conservation of energy, which led to the development of the first law of thermodynamics.
In engineering and thermodynamics, a heat engine performs the conversion of heat energy to mechanical work by exploiting the temperature gradient between a hot "source" and a cold "sink". Heat is transferred to the sink from the source, and in this process some of the heat is converted into work. A heat pump is a heat engine run in reverse ...
