There is no theoretical impossibility to directly convert heat (infrared radiation) into electricity. There is an almost inexhaustible source.

All that we know how to do now (thermal engine, photovoltaic cell, thermogenerator ...) requires a temperature difference between 2 "thermal baths". Thus, if your photovoltaic cell is at the temperature of the radiation that you receive, IR or not, it will no longer work. It is a consequence of the second law of thermodynamics. If it is false we wait for the demo, because so far we have no confirmed counter-example.

What we were talking about with Karpen's pile and the "Maxwell's demon" is precisely obtaining useful work from a single thermal bath, so with a process that cools the medium to draw energy from it, and with diminishing entropy. It would be a revolution, since the door is open to perpetual motion.

It's an interesting experience. An idea for voltage and current obtained?

It was in the order of volt (empty) and mA (shorted). These values ​​are too strong, I certainly had chemical reactions. And then heating the solution should have increased the current, I checked that it was not the case.

For oxygen, why not place the battery in a closed bottle?

It does not remove oxygen. One solution: a vacuum pump. But the problem is much more complex than that. For example the metals of the electrodes have been able to absorb gases in their past, the water used too, so that it is very difficult to distinguish the weak current which would come from the Karpen principle of that much more probable of an electrolytic reaction. .

It seems like.
We are dealing with a dreamer who has no sense of reality. For example it will not get a field of 500 KV / m in the holes: the surface of the dielectric being at the same potential as the grid, it will have ... 0V / m! His drawing at the top of the 13 page is completely wrong. The field lines extend from the bottom of the grid to the hot plate, they never go up to go through the holes.

Rather than make a big speech and images of Epinal, he would be more inspired either to write the equations, he would see immediately or that wedge, or to produce a proof of concept, which does not need fields too disproportionate than 500 KV / m, but accurate measurements.

The basic idea, a game between electrostatic acceleration and thermal agitation, is not to eliminate, there may be digging, there.

The machines invented by Willi von Unruh and Hans Coler are based on the use of copper wire coils winding in a particular manner around cylindrical bars constituted by a ferromagnetic material (iron).

The action of magnetic field (s) (created by DC and / or AC currents) on a ferromagnetic material (iron, nickel, cobalt, alloys) is known to produce mechanical vibrations and deformation of the material (magnetostriction) which can contract, lie down or undergo torsional stress, thus modifying its internal atomic arrangement.

Two new branches of magnetic material physics, in relation to the development of nanotechnology, have recently appeared: spin-spin electronics that take into account the quantum spin property of the electron in addition to its charge and the study of magnetic skyrmions which deals with the conditions of creation, statibility and diffusion of particular dynamic magnetic structures, comparable to vortices, comparable to quasi-particles, manifested in certain types of atomic geometries and usable to convey information at the atomic scale for future quantum computers.

Recent studies have shown that skyrmions can be paired and manipulated by electric spin currents.
In the hypothesis that such pairs of quasiparticles can behave as real pairs of coupled electrons that can propagate coherently in non-magnetic metals, we could connect the electric current produced by Willi von Unruh and Hans Coler to a new form of superconductivity (phenomenon which is characterized by the absence of electrical resistance, from where of heating, of the conductive material). At present, superconductivity (which would be the ideal solution to the problem of storing electricity compared to current chemical batteries) has only been observed at low temperatures.

The in-depth understanding and mastery of such devices, to generate and store an electric current at room temperature, could be a real technological revolution.

When one looks at the diagram of the device replicated by Hans Coler in the report of the British Secret Service of 1946 (declassified in 1979), three remarks are necessary:

two ends of the wire that wraps around each of the six ferromagnetic cylindrical bars are welded to the surface of the magnet
all of these 6 magnetoelectric elements are placed in attraction mode to form a hexagonal loop
the circuit formed by the 6 magnetoelectric elements can be broken down into two coupled subcircuits (via the two coils sliding one inside the other) each supplying a capacitor, a portion of the current generated at the output of each capacitor one circuit being sent to the input of the other circuit

The first point indicates that the electric current flowing in the coil is injected directly into the magnet then back into the coil (necessary condition to have a closed electrical circuit), which allows to obtain a polarized current resulting from the interaction spins of electrons with the magnetic moments existing in the magnet. In my previous contribution, I proposed a mechanism to explain the amplification of the electric current by the formation of dynamic vortex magnetic structures (skyrmions) that can behave like sets of coupled electron pairs moving under the action of the current biased to constitute a superconducting current.

The second point could provide an answer to the origin of the energy used to form these aggregates of "electrons": the hexagonal loop could indeed play the role of an antenna to collect electromagnetic energy from the external environment. (quantum fluctuations of the vacuum, energy generated by radio electromagnetic waves, or even by the earth's magnetic field).

The third point indicates that one is in the presence of self-oscillating circuits whose oscillations were initiated spontaneously (via the adjustment of the distance between the magnets and the adjustment of the coupling between the 2 sub-circuits by sliding the 2 coils).

It is clear that the development of this type of electric generator could provide a clean energy solution within the framework of sustainable development.

Either the explanations are good but we are still waiting (impatiently) independent measurements on this kind of prototypes ...

The replication of Coler's magnetic apparatus is complex because the 1946 UK document does not provide precise technical information on the different elements used (capacitor capacitance value, number of turns of the inductor coils, thickness of the copper wire used , nature of the magnets ...).
Indeed, the characteristics of the magnets (chemical composition, presence of magnetization defects or chemical defects ...) could play a decisive role in explaining the results obtained.
For example, in his analysis, Chavascience evokes the role that could be played by the 57 isotope of iron (present at a rate of 2% in natural iron) to explain the value of the frequency of the measured current.
Thus, modern magnets, containing less impurities and having stronger and more homogeneous magnetization than the magnets used in the 20-40 years, may not be appropriate.

The two German inventors seem to have built their protopypes in a relatively empirical way, relying on arguments that are qualified as unscientific.
In addition, few scientists in Germany (with the exception of the German Navy of the 3rd Reich, interested in the possibilities offered by these electric generators to replace the batteries of its submarines), despite having seen these devices in operation , agreed to collaborate in their study, for fear of being discredited by the scientific community because such devices fall into the category of "perpetual motion machines", violating Newton's principle of conservation of energy.
However, it should be noted that this principle only applies to isolated physical systems (ie not exchanging material or energy with the outside) whereas if we consider that these devices derive their energy from their interaction with the environment outside, we are in the presence of open physical systems.

In the same category of "scientifically impossible machines", we find the EM-drive (Electromagnetic Drive), an asymmetric electromagnetic resonant cavity thruster, proposed in 2001 by the British aeronautical engineer Roger Shawyer.
This electric propulsion system would produce a thrust without fuel, without ejecting mass, or emitting radiation, thus violating Newton's principle of conservation of momentum.
Although the Chinese in 2008, then NASA in 2015 have obtained positive results (contraindicated because the measured effect being of very small amplitude, one could be in the presence of parasitic effects), the scientific community is divided because the different theories advances put into question quantum physics (by playing an active role in the quantum vacuum, which could also have repercussions on particle physics), theories of Maxwell's electromagnetism and Einstein's general relativity.
If the experimental results are confirmed, the EM-Drive could be the first quantum thruster (Q-Drive), making it possible to make interplanetary trips in the Solar System, reducing the duration of the journeys and therefore the exposure of astronauts to harmful effects of cosmic radiation and weightlessness.
Moreover, the integration of the notion of quantum vacuum in physical theories could also provide the link, long sought by Einstein, between electromagnetism and gravitation, thus opening the way to the control of gravitation.

Hello,

These 2 words do not go together.
Fumisterie, yes because it goes against the laws of physics, so not scientific.
For EMdrive, it's clear https://fr.wikipedia.org/wiki/EmDrive#E ... 3.A9orique

Indeed, the expression "scientific hoax" is an oxymoron, but by this shortcut, Moinsdewatt meant that it was a real humbug, disguised under pseudo-scientific clothing ...
