Die Energiemedizin ist ein Zweig der Alternativmedizin, der auf dem pseudowissenschaftlichen Glauben beruht, dass Heiler "Heilenergie" in einen Patienten leiten und positive Ergebnisse erzielen können. In den meisten Fällen ist keine empirisch messbare Energie im Spiel: Der Begriff bezieht sich stattdessen auf so genannte feinstoffliche Energie. Praktizierende können die Praxis als "hands-on", "hands-off" und "distanziert" klassifizieren, wobei sich Patient und Heiler an verschiedenen Orten befinden. Es gibt viele Schulen der Energieheilung, die viele Namen tragen: z. B....

Osmosis (/ z mo s s/, US also/ s-/) is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential (region of higher solute concentration), in the direction that tends to equalize the solute concentrations on the two sides.It may also be used to describe a physical process in which any solvent moves across a selectively permeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations....

La médecine énergétique est une branche de la médecine alternative fondée sur une croyance pseudo-scientifique selon laquelle les guérisseurs peuvent canaliser une "énergie de guérison" vers un patient et obtenir des résultats positifs. Dans la plupart des cas, il n'y a pas d'énergie empiriquement mesurable en jeu : le terme fait plutôt référence à une énergie dite subtile. Les praticiens peuvent classer la pratique en trois catégories : pratique directe, pratique indirecte et pratique à distance, où le patient et le guérisseur se trouvent dans des lieux différents. Il...

The development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries' energy security through reliance on an indigenous, inexhaustible and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating climate change, and keep fossil fuel prices lower than otherwise. These advantages are global. Hence the additional costs of the incentives for early deployment should be considered learning investments; they must be wisely spent and need to be widely shared.Converting solar...

The environmental impact of the energy industry is diverse. Energy has been harnessed by human beings for millennia. Initially it was with the use of fire for light, heat, cooking and for safety, and its use can be traced back at least 1.9 million years. In recent years there has been a trend towards the increased commercialization of various renewable energy sources. Rapidly advancing technologies can potentially achieve a transition of energy generation, water and waste management, and food production towards better environmental and energy usage practices using methods of systems ecology...

Energy development is the field of activities focused on obtaining sources of energy from natural resources. These activities include production of conventional, alternative and renewable sources of energy, and for the recovery and reuse of energy that would otherwise be wasted. Energy conservation and efficiency measures reduce the demand for energy development, and can have benefits to society with improvements to environmental issues.Societies use energy for transportation, manufacturing, illumination, heating and air conditioning, and communication, for industrial, commercial, and...

Various materials and transduction mechanisms have the ability to convert vibratory energy to useful electrical energy, such as piezoelectric, electromagnetic, and electrostatic generators. Piezoelectric transducers, with their inherent electromechanical coupling and high power density compared to electromagnetic and electrostatic transducers, have been widely explored to generate power from vibration energy sources.Many researchers have reported novel applications of piezoelectric energy harvesting technology in the past decade. While the body of literature in the field of piezoelectric...
