Group: Experimentalist Hero Member Posts: 2072	Hi everybody, It is a self-charging chemical cell, oscillating between charge and discharge, based on negative resistance and negative capacitance. The paper just came out. Even if it's only about power of minus 1mW, it sounds interesting, but I don't understand where the energy comes from. Can someone explain it? https://aip.scitation.org/doi/10.1063/1.5132841 --------------------------- "Open your mind, but not like a trash bin"

All matter is always vibrating, oscillating and orbiting so it's just a matter of moving electrons on that level or coordinating the motion on a larger level. Think casimir effect with the material between the plates being inherently unstable and never finding equilibrium. Now introduce a mechanism to produce a one way flow of electrons from said oscillations like a check valve. You see the problem is not energy as it is already everywhere in everything. The problem is a better way to transform the energy we know is everywhere into a more useable form. --------------------------- Comprehend and Copy Nature...

Group: Tinkerer Hero Member Posts: 1770	Now I want to make ferroelectric glass. I've sent to RMS as well to see if he is across it. Thanks F6 edit. Just looked up alkali catations Lithium, Sodium, Potassium, Rubidium, Caesium, & Francium. Hopefully it's just sodium?

Quote ABSTRACT The ability for electrochemical cells to self-charge for extended periods of time is desirable for energy storage applications. While self-oscillation is a phenomenon found in human-made dynamic systems and in nature, its appearance in electrochemical cells has not been reported or anticipated. Here, we chose an electrochemical cell containing two electrodes separated by a self-organizing glass electrolyte containing alkali cations. The ferroelectric character of the electrolyte, with an impressively high dielectric constant of 106–107, supported self-charge and self-oscillation. After fabrication, the cells were characterized to determine the electrical impedance, dielectric spectroscopy, and electrochemical discharge. The electrochemical cells also displayed negative resistance and negative capacitance. Negative capacitance is due to the formation of an inverted capacitor between the double-layer capacitor formed at the negative electrode/electrolyte interface and the dipoles of the ferroelectric-electrolyte. Negative resistance is triggered by the formation of an interface phase, which leads to a step-change of the chemical potential of the electrode. The electrochemical cell demonstrates an entanglement between negative resistance, negative capacitance, self-charge, self-cycling, and the activation energy vs thermal energy or external work. The phenomenon of self-cycling is enhanced at low temperatures where the activation energy is higher than the thermal energy. This demonstration extends the Landau-Khalatnikov model for a ferroelectric to a bistable device in which the bistability resides in an electrode. The results reported here reveal the first report of negative capacitance and negative resistance existing in the same process, which can lead to valuable advancements in energy storage devices and in low-frequency applications.

Group: Experimentalist Hero Member Posts: 2072	I'm no more advanced, although with the coronavirus in France, we are confined and have time for research. It's like a Maxwell demon without them daring to say it. But I'm not sure, it's beyond me. --------------------------- "Open your mind, but not like a trash bin"

Group: Moderator Hero Member Posts: 2735	F6FLT If energy and mass cannot be created or destroyed only transformed then FE is equivalent to Maxwell's Demon. Trans-to change, form- shape,arrangement. Thus organizing or arranging something already present and in motion constitutes what we see as FE. The concept of energy and FE is actually very easy and intuitive to understand. --------------------------- Comprehend and Copy Nature...
