But maybe so ...GreenV8S said:Maybe you do.
Stirling engines are well known. That drawing shows an extremely crude one. Even very well designed ones have a hopelessly low power density and have no practical application.
As you can see, I posed such a problem two years ago ..Here is the thermodynamic problem .. We have in a box, in a vacuum is a set of thermal engines with generators ... Will this set be more efficient than it would be normally installed without a box?
it's about how laws of thermodynamics work on the Equator, and how on the Pole.
on the Equator 40 degrees Celsius and at the Pole - 40 degrees Celsius also for efficiency and the layout of the engine will be important ...?
So outside the box, only the water to be cooled is transmitted to the cooler and back and the resulting electric current. The heat can be supplied outside the box at normal atmospheric pressure. The efficiency of the device increases 10 times (or 100).
The steam does not go anywhere, because it is in a closed circuit, and the water is similar, it does not need to be topped up, but only cooled ..
Such "boxes" can be installed downstairs in mines to produce electricity .. with high efficiency .. But basically any source of heat can be used ..
The second law of thermodynamics, she forgot to say that the efficiency of a heat engine depends not only on the temperature difference, but also largely on the pressure at which the system works.
