Thermal energy mechanical work produced

Thermal Energy Produces Mechanical Work of Lifting a Weight (Heating Through the Temperature Interval Drives Contraction)... 

Examining these structures and the fact that they are all powered by ATP, the question remains as to how force is actually produced. Geeves and Holmes (2005) argue that myosin acts by the specific coupling between different myosin head states and different positions of the lever arm on the motor domain, so that, once attached to actin, the myosin acts as an ATP-driven motor where the energy released by ATP hydrolysis is direcdy coupled to the performance of mechanical work. However, Marx et al. (2005) argue that in some cases the kinesins appear to act as thermal ratchets. In this case, the attachment of a second head, once the first head has bound, is an event controlled by thermal motion, but, presumably for steric reasons, the head is more likely to bind to the microtubule in the... 

It is convenient to note Kelvin s statement of the second law rt ijs impossible to have a natural process which produces no otjier effect than the absorption of heat from a single reservoir and the performance of an equivalent amount of work. This i s obviously a consequence of the inevitable approach to equilibrium, since if Kelvin s statement were violated, the work could be done back on the reservoir while something spontaneously moved, and we would have a device that could wiggle forever. Kelvin s statement stresses how hard it is to turn random thermal energy of a heat flow into organized mechanical energy of work. The reverse, turning work into heat, is of course no problem at all. 

A heat engine makes use of thermal energy to produce mechanical energy, designated usually as shaft work. Steam and gas turbines are the most important applications of heat engines in process industries. 

The human heat balance equation is used to describe the balance of the thermal system of a person. There have been many models proposed, the aims of which are to show the balance of the metabolic heat production—the metabolic energy produced (M) minus the energy of mechanical work done (W)—and the sum of all the heat loss systems, including the rate of heat storage (i.e., whether the system is heating up or cooling down) (Fanger, 1972 Parsons, 2002). 

Thermal Energy (TE), Measurable as the Heat of the Transition of the Band Under Load, AHi, Produces Mechanical Work (MW) of Lifting a Weight, That Is, TE MW... 

The concept of systems transforming chemical energy directly into mechanical work has been investigated for many years. Such systems would be much more efficient in terms of fuel consumption than conventional thermal engines which first convert chemical energy into heat or electricity and then the latter into mechanical work. A one-step conversion is also expected to produce less waste products and work noiselessly.
