The theme of this website is the physical comparison between experiment and theory of perpetuum mobile claims and overunity operation. Interesting are the conditions where overunity devices might work and where not. To promote discussions ideas are spread here at a suboptimal workbench level of different degrees of quality. 
The website is published mainly as a individual, private and non-profit initiative.
If it is not noted otherwise the author does not speak for any institution or company but only for himself.
We will do our best to present correct facts. But especially in this area of science errors may be possible at this initial hobbyist level under the present restrictions. It is the policy of this page to raise the discussion of overunity to a scientific level by steady following the theme. So be careful: You are here on glazed frost. If you believe in these things you are doing this in your own responsibility !

Cooling cycles in superconductors calculated by dynamical London theory   
  WDB-Verlag Bad Buchau 2024 ISBN 978-3-9801452-5-1 , 14 pages   15.- Euro
The classical London theory is extended in order to predict the time-dependent behavior of superconductors. Different to prior models it contains a 2-fold time derivative of the magnetic field B and includes the self induction of the superconducting probe. It predicts an inverted (gain)-hysteresis in the M-H diagram for non-stationary cycles which violates the 2nd law. The gain estimated is measurable. The article can be downloaded here !

About Energy Conservation, Second Law and Overunity  
  WDB-Verlag Berlin 2015 ISBN 978-3-9801452-4-4, 182 pages   ( out of print! )
The book has a theoretical approach. It makes some reports about working perpetuum mobiles understandable because it reduces any mystified super hyper high tech concept to simple scientific common sense ready for engineering. Serious perpetuum mobile claims are explained as analoga to wind wheels. They can be described by non-conservative field mathematics. The book is the most actual update of the article collection of this website. It contains much new material like a discussion of inverted hysteresis systems. All information in this monography is carefully referenced. The contents of the book you find here !

2) Kink conditions for isobars in binary v-x-phase diagrams induced by the second law
W.D. Bauer, W. Muschik, Archives of Thermodynamics Vol.19, No.3-4,   1998, p.59-83

Abstracts:
Conditions describing the behavior of the kink of isobars at the dew line in v-x- phase diagrams of binary mixtures are proved using the second law. They are interesting in connection to the compatibility of Serogodsky�s and van Platen�s cycles with the second law of thermodynamics. The conditions are tested using a generalized Bender equation of state with mixture rules of Tsai and Shuy. The second article contains additionally the complete set of formulas useful for programming for modifying these equations of state.

5) The generalized first law and thermodynamic cycles   released 6.12.99

Abstract:
The article represents the first law as abstract mathematical definition to describe cyclic processes. Acc. to the author it has nothing to do whether a quantity like energy can be measured balanced experimentally.
Furthermore the van Platen cycle is presented. The general thermodynamical theory of the problem is written down and applied to a (quite lenghty) Bender equation of state describing a mixture. The main line of the computer calculation is explained. The van Platen cycle is calculated.
As results profiles of pressure, concentration and spec. volume versus the radius of a centrifuge are shown. In effect a overunity cycle of the van Platen cycle is not possible.

6) The parametric overunity rotator - the Wuerth power booster
released 13.11.99, withdrawn 28.2.00, revised 10.4.00, corrections 15.4.00, big update 11.9.00
for the new preprint pdf - file (Acrobat 4.0) from 30.10.2001 download click here

Abstract:
A simple mechanical setup proposed and built by F. Wuerth is calculated acc. to theoretical mechanics. The calculation predicts no overunity behaviour due to parametric changing moment of inertia. The calculation of the author is supported by his own experimental observations. Experiments of Wuerth und Bucher deviate from the prediction of classical mechanics.

   A evaluation proposal for the Wuerth centrifugal pumper released 2.7.02

Abstract:
Wuerth's centrifugal pumper is proposed for evaluation. Acc. to Wuerth the cause of the claimed overunity are forces deviatiating from classical mechanics. A setup to check this forces is proposed. Acc. to theoretical mechanics no overunity is possible. A calculation method is presented which allows to describe the behaviour of the pumper from classical mechanic. This method has the advantage that no inertial tensor are needed for description.

Test of electrical overunity claims
 

7) The Brown-Ecklin generator

Abstract:
A theoretical electromechanical model of Brown's generator is simulated. It proves the possibility of overunity work efficiency confirming Brown's measurements qualitatively. The energy balance of this machine is discussed. Improvements of the models are proposed to fit the the model closer to reality. The technology adapting this generators to today electrical energy production and consumption is outlined. In Part 4 we built a modified Brown-Ecklin type flux-switch generator and tested its efficiency. The test results do support the usual belief in energy conservation. The results are in contradiction with our theoretical prediction. The causes of this discrepancy are discussed.

Abstract:
It is shown that non-conservative force-field can be generated by a construction using a permanent current distribution including iron as magnetic shielding material driving permanent magnets as rotors giving off mechanic energy. This motor changes the torque in the magnetic field into motion.

8) Do non-conservative potential perpetual running machines exist ?
released 26.6.97 some additions 8.7.97 revised 5.5.98

Abstract:
It is shown that a system of coupled cog-wheels obeys a non-conservation relation of angular momentum.
It is shown shown by an example that a changing charge in a (conservative) ratched potential is subjected to a non-conservative force field which generates a perpetuum mobile cycle. It is shown that this model supports the perpetuum mobile claims of the Watson-Hartmann SMOT device only if it is assumed that magnetisation of the moving iron material depends from field gradient dH/dx as well which can be present in micromagnetism. A nonlinear dependence of magnetisation from the field H alone gives no perpetuum mobile cycle. This fact is analogous to the known behaviour of electric cycles of non-linear capacity and coil.

9) The Zaev-effect

Abstract:
The Zaev effect is a electro- or magnetocaloric effect which is claimed to violate the Second Law. The effect appears if a capacitance is charged and discharged with different velocities. Then under certain conditions more output than input energy needed comes from the capacitance probably due to a conversion of heat into electricity during the cycle. For introductional reading and following the last discussions, see here.
A differential equation is developed which calculates the the thermal hysteresis of an arbitrary material in an electric cycle. It is shown by a numerical example for susceptibilities dependent in first order from E that the Zaev effect can not be produced as a classical electrocaloric thermodynamic effect. Experimental data from Partington et al. suggest that such an effect may exist if the paraelectric material properties show relaxation under voltage, i.e. if they are time dependent. In Part III literature references are discussed which seem to confirm the experimental data and give an outlook on new possible theoretical interpretations of these effects.

10) The Maxwell equations including magnetic monopoles   released 29.1.04

Abstract:
The derivation of the Maxwell equations is reproduced whereby magnetic charges are included. This ansatz yields following results:
1) Longitudinal Amp�re forces in a differential magnetostatic force law are improbable. Otherwise a electric current would generate magnetic charges.
2) Simple magnetic and electric induced polarization phenomena are completely analogous and are described by a Laplace equation.
3) Permanent magnetic fields can be understood to be caused by magnetic charges. Consequently, a moving permanent magnet represent  a magnetic current which generates a electric field. Applications of this theory could be Hamel-spinner and Searl-disk.
4) The electromagnetic tensors of energy and momentum have some additional terms which are written down generally.
5) If the electric material parameter are influenced by non-electric variables (for instance temperature or pressure), the formalism of electrodynamics is not sufficient to describe the system and has to be completed by further differential equations from the other areas of physics.
6) Nonlinear electro-thermodynamic systems may violate the second law of thermodynamics. This is illustrated by a electric cycle with a data storing FET invented by Yusa & Sakaki.
