Pneumatic motor from the expansion of the gas. These days, using the patent pending 'K'Air Generator', converted to work as a compressed-gas motor, the project should be launched in 2010, thanks to a North American group of investors, but for the purpose of developing first a green energy power system. In the original Nègre air engine, one piston compresses air from the atmosphere to mix with the stored compressed air (which will cool drastically as it expands). This mixture drives the second piston, providing the actual engine power. MDI's engine works with constant torque, and the only way to change the torque
Potential energy another electrically charged object nearby. The work "W" required to move "q" from "A" to any point "B" in the electrostatic force field is given by typically given in "J" for Joules. A related quantity called "electric potential" (commonly denoted with a "V" for voltage) is equal to the electric potential energy per unit charge. The energy of a magnetic moment formula_44 in an externally produced magnetic B-field has potential energy The magnetization in a field is where the integral can be over all space or, equivalently, where is nonzero. Magnetic potential energy is the form of energy related not
