A Cautionary Note on the Second Law of Thermodynamics

Authors: Jeremy Dunning-Davies
Comments: 4 Pages.

Entropy and its physical meaning have been a problem in physics almost since the concept was introduced. Here questions are raised over the correctness of the idea that the Second Law of Thermodynamics may be expressed simply as 'the entropy never decreases'.

Comparative Studies of Law of Conservation of Energy and Law Clusters of Conservation of Generalized Energy—No.3 of Comparative Physics Series Papers

Authors: Fu Yuhua
Comments: 6 Pages.

As No.3 of comparative physics series papers, this paper mainly discusses the comparative studies between the original law of conservation of energy and the Computer Information Library Clusters; and based on the multiform laws of conservation of energy, the concept of "law clusters of conservation of generalized energy" is presented. In which, any physical quantity can be regarded as "generalized energy", and any physical formula and equation can be transformed into law of conservation, therefore all the physical laws as well as formulas and equations can be classified as "physical law clusters of conservation of generalized energy" (sometimes it can be simplified to "law clusters of conservation of generalized energy"). While in law clusters of conservation of generalized energy, there are some source laws. According to the source law, some related laws as well as formulas and equations can be derived, for example, law of gravity and Newton's second law can be derived with law of conservation of energy; thus "law clusters of conservation of generalized energy" can be simplified to "law clusters of physical source law". As the number of source laws in the law clusters is reduced to some degree, all the laws of physics are able to be written on a T-shirt with the form of "the simplest law clusters of physical source law". In order to deal with the practical problems, "variational principle of the simplest law clusters of physical source law" can be eatablished.

Proposal to Test the Validity of the Second Law of Thermodynamics

Authors: Radhakrishnamurty Padyala
Comments: 6 Pages.

The concept of ‘thermal heating efficiency’, G, considered as a duel of Carnot efficiency, offers a suitable method to test the validity of second law of thermodynamics. This concept claims to offer us many practical (therefore, experimentally testable) advantages, specifically, economy in heating houses, cooking, besides others. For example, if one unit of fuel when burnt inside the house gives Q joules of heat, the thermodynamic method based on this concept offers as much as 10 Q joules for the same one unit of fuel, giving a 10 fold economy in heating houses. We show in this article that the economy claimed is a myth and we can get no more heat into the house using this method than that we get by burning the fuel inside the house. We propose, the concept of thermal heating efficiency as a suitable method to test the validity of the second law of thermodynamics.

Estudo do Sistema Pelamis Para Captação de Energia Maremotriz

Authors: A. Gobato, D. F. G. Fedrigo, R. Gobato
Comments: 1 Page. Panel presented at the XIX Physics Week, at the State University of Londrina, from September 15 to 19, 2014.

Many sources of energy have been researched for their proper capture, where some stand out for their ease of obtaining, others for low cost and others for being renewable. Here we study a source of energy - the sea wave, whose capture is still under development. This energy comes from the sea waves and is 100% renewable, and the treatment system here is the Pelamis System. Over the years the energy has become vital for the human being, allowing us comfort, leisure, mobility among other factors. The search for cheap and renewable energy sources has grown significantly in recent years, mainly to a diminishing effect that has degraded nature, enabling scientists and engineers to search for new technologies. Some countries where there are not many forms of energy capture, such as sources of alternative sources such as wind, solar, thermoelectric, marine energy and many others. Among the methods of energy capture mentioned above, a project created by Chinese in 1988, with the intention of being an infinite and totally clean energy source that caught our attention. It is a system that is not generated by the movement of the waves, this project is called Pelamis.

Energy Efficiency and Entropy

Authors: Binyamin Tsadik
Comments: 1 Page.

This paper represents an intuitive approach to understanding Entropy. We can thus associate entropy for all forms of energy based on a known form. Boltzmann's Equation will allow us to determine chemical entropy for chemical energy and based on this we can determine the entropy for all forms of energy.

Is Production of Energy "For Free" Feasible in a PhR Perspective?

Authors: W.Berckmans
Comments: 20 Pages.

The Physical Reality (PhR) model recently presented in is the outcome of an alternative approach to studying cosmic behavior. It implicitly extends the principle of energy conservation to the whole cosmos since its creation out of nihil. This article concludes that under such scenario an attempt to produce energy "for free" (e.g. by cold fusion) would not be doomed to fail.
