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
Binding energy Binding energy Binding energy (also called separation energy) is the "minimum" energy required to disassemble a system of particles into separate parts. This energy is equal to the mass defect - the amount of energy, or mass, that is released when a bound system (which typically has a lower potential energy than the sum of its constituent parts) is created, and is what keeps the system together. If the energy supplied is more than the binding energy, then the disassembled constituents possess non-zero kinetic energy. In general, binding energy represents the mechanical work that must be done against the forces
