Clearly, the negative effects of all this may be alleviated a bit by selecting proper and low-cost energy sources and resources and using these as effectively as possible with zero or a minimum of negative side-effects. In practice, this implies a central role in the fine balance between economic growth, a risk of modern slavery, exploitation of the Earth's resources and global environmental problems such as climate change and scarcity of water, often leading to armed conflict. (§7.This text (based on the opening keynote talk for CPOTE-2020) addresses the role of engineering thermodynamics in a world where mankind wishes to have access to low-cost energy. (§6.) The principle of dynamical reversibility does not apply when (external) magnetic fields or Coriolis forces are present, and the reciprocal relations break down. (§5.) The conditions for stationary flow are formulated the connection with earlier quasi-thermodynamic theories is discussed. Lord Rayleigh's 'principle of the least dissipation of energy' is generalized to include the case of anisotropic heat conduction. (§4.) The reciprocal relations can be expressed in terms of a potential, the dissipation-function. Reciprocal relations for heat conduction in an anisotropic medium are derived from the assumption of microscopic reversibility, applied to fluctuations. (§§1-2.) The analogy with a chemical monomolecular triangle reaction is discussed in this case a a simple kinetic consideration assuming microscopic reversibility yields a reciprocal relation that is not necessary for fulfilling the requirements of thermodynamics (§3).

A general class of such relations will be derived by a new theoretical treatment from the principle of microscopic reversibility. These earlier derivations may be classed as quasi-thermodynamic in fact, Thomson himself pointed out that his argument was incomplete, and that his relation ought to be established on an experimental basis.

of electrolytic cells with liquid junction.

For certain cases of such interaction reciprocal relations have been deduced by earlier writers, e.g., Thomson's theory of thermoelectric phenomena and Helmholtz' theory for the e.m.f. Examples of coupled irreversible processes like the thermoelectric phenomena, the transference phenomena in electrolytes and heat conduction in an anisotropic medium are considered.
