We are bathed in a wave environment (e.g. tv/radio/mobile waves). Could we harness this immense energy?

 

On the occasion of the DARPA Demo Day at the Pentagon and the presentation of its projects as referenced at the following tweet, a past project on Vaccum is cited.

Quantum Vacuum - Source of Energy and Wonder

 

Reposting excerpt from a lecture by Michel Spiro, Former President of the CERN Council 2010- January 2013, which is mentioned further down this page

 

"When protons and electrons move they produce light. This light is propagated everywhere, in the entire universe and therefore we have radiation in the entire universe. Even where we do not have particles, we have radiation. Therefore one could argue that we can’t say we have nothing, or that we have a vacuum because we have radiation."

 

"If we take a small box and we manage to empty it from particles, it could be said that particles outside that are close to it emit radiation that enters the box. What if we use material that does not allow radiation to enter? The material has a temperature. This means it emits radiation."

 

 

The Casimir effect and the forces of the vacuum

 

Bring two conductive plates, two mirrors in a vaccum at a distance of 10nm. An attractive or repulsive force will be exerted between them.

 

https://en.wikipedia.org/wiki/Casimir_effect

"In fact, "Casimir's original goal was to compute the van der Waals force between polarizable molecules" of the conductive plates."

The Casimir effect explained by Scientific American

"Now, if mirrors are placed facing each other in a vacuum, some of the waves will fit between them, bouncing back and forth, while others will not. "

 

 

 

The Energy of the Vacuum

"Harnessing the Wheelwork of Nature: Tesla's Science of Energy"

Quoting the title of a book by Thomas Valone - Link to Google books

 

Quote from this link - "Earth Power - A useable energy source"

“Throughout space there is energy, it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of Nature….The knowledge that there is throbbing through the Earth, energy available everywhere, would exert a strong stimulus on students, mechanics and inventors of all countries. This would be productive of infinite good. Conditions such as never existed before would be brought about. It would enable Man to dispense with the necessity of mining, pumping, transporting and burning of fuels, and so do away with innumerable causes of waste! New frontiers might be opened, unlimited power for all the world, inexpensive power for the farmer to light and heat his home, to drive his tractor, to harvest his grain, to increase his food output, electric power for millions of homes, so economical that every appliance could be operated electrically. The real beginning of a ‘Golden Age of Civilization.”

Excerpts (translated in English):

 

Part I: The concept of Vacuum

 

Does vacuum really exist?

 

The air that surrounds us is full of particles. In the laboratory we can take a small box and use a pump to remove all particles and create a vacuum.  But still there will be a significant number of particles.

 

If we take into account the space around a satellite, or the interplanetary space or space between galaxies, we can consider that we have a few electrons and protons in one meter cube. This could be considered an approximation of vacuum. This is defined as classic vacuum.

 

When protons and electrons move they produce light. This light is propagated everywhere, in the entire universe and therefore we have radiation in the entire universe. Even where we do not have particles, we have radiation. Therefore one could argue that we can’t say we have nothing, or that we have a vacuum because we have radiation.

 

If we take a small box and we manage to empty it from particles, it could be said that particles outside that are close to it emit radiation that enters the box. What if we use material that does not allow radiation to enter? The material has a temperature. This means it emits radiation.

Le vide quantique et viscosité

"Le vide quantique n’est pas aussi vide que l’on pourrait l’imaginer. C’est déjà vrai pour le vide classique puisque si dans une enceinte vous faites le vide, vous pompez toutes les molécules que vous pouvez, il n’empêche que les parois aussi rayonnent et vous ne pouvez pas enlever ce rayonnement même conceptuellement. Vous avez toujours quelque chose dans le vide classique. Dans le vide quantique encore plus parce que les relations d’incertitudes font que si on l’observe de très près, dans un temps bref, il fluctue ; le vide quantique est considéré comme l’état d’énergie le plus bas. Il peut être plein de fluctuations quantiques et donc on le considère comme un quasi milieu. Le boson de Higgs confère à ce quasi milieu une sorte de VISCOSITE et ce sont les particules qui, à travers cette interaction avec le vide quantique, acquièrent une masse."

 

 

Nous sommes nés du vide !

ORIGINES par Marie-Odile Monchicourt dimanche 27 juillet 2014

 

« la matière, tout ce qui nous entoure, est probablement issu de fluctuations quantiques du vide. Ces fluctuations quantiques sont à l'origine du Big Bang, puis ensuite à travers un changement de phase lié au boson de Higgs, l'origine de la matière et de la lumière, de la masse telle qu'on la connait. C'est un apport philosophique majeur, conclut Michel Spiro. Un bouleversement de conception qui a des conséquences anthropologiques."

 

 

 

 

 

The notion of "Aether" in Philosophy

 

https://en.wikipedia.org/wiki/Aether_(classical_element)

According to ancient and medieval science, aether (Greek: αἰθήρ aithēr[1]), also spelled æther or ether, also called quintessence, is the material that fills the region of the universe above the terrestrial sphere.

 

Fifth element

In Plato's Timaeus (58d) speaking about air, Plato mentions that "there is the most translucent kind which is called by the name of aether (αίθηρ)".[6] but otherwise he adopted the classical system of four elements. Aristotle, (...)
