In the past, energy was discussed in terms of easily observable effects it has on the properties of objects or changes in state of various systems. Basically, if something changed, some sort of energy was involved in that change. As it was realized that energy could be stored in objects, the concept of energy came to embrace the idea of the potential for change as well as change itself. Such effects (both potential and realized) come in many different forms; examples are the electrical energy stored in a battery, the chemical energy stored i ...

Energy is a measure of being able to do mechanical work.[1] This is a fundamental concept pertaining to the ability for action. In physics, it is a quantity that every physical system possesses. This quantity is not absolute but relative to a state of the system known as its reference state or reference level. The energy of a physical system is defined as the amount of mechanical work that the system can produce if it changes its state to its reference state; for example if a liter of water cools down to 0°C or if a car hits a ...

Energy storage as a natural process is billions of years old - the energy produced in the initial creation of the Universe has been stored in stars such as our Sun, and is now being used by humans directly (e.g. through solar cells) or indirectly (e.g. by growing crops). As a purposeful activity, energy storage has certainly existed since pre-history, though it was often not recognized as such. An example would be the use of logs or boulders as defensive measures in ancient forts - the logs or boulders would be collected at the top of a hill, and the energy thus stored would ...

Jolt Cola was one of the first energy drinks available in North America, being originally released in the 1980s. It was essentially just an extremely high caffeine, high sugar brand of cola. It pioneered the marketing strategy still widely in use by energy drinks today, targeting a generally younger audience, mostly students and professionals, important 'on the go' people, and billing itself as something that was not necessarily healthy but which would allow them to cram more hours into their day. Later, marketing turned further and further ...

The cosmological constant was first proposed by Einstein as a mechanism to obtain a stable solution of the gravitational field equation that would lead to a static universe, effectively using dark energy to balance gravity. Not only was the mechanism an inelegant example of fine-tuning, it was soon realized that Einstein's static universe would actually be unstable because local inhomogeneities would ultimately lead to either the runaway expansion or contraction of the universe. The equilibrium is unstable: if the universe expands slightly, ...

The concept of zero-point energy originated with Max Planck in 1911. The average energy of a harmonic oscillator in thermal equilibrium with its surroundings is: Here, is Planck's constant, ω is the natural frequency, k is Boltzmann's constant, and T is the temperature. At the same time Albert Einstein, L. Hopf (1910) and Otto Stern (1913) were also studying the properties of zero-point energy. Shortly thereafter Walther Nernst (1916) proposed that empty space wa ...

Vacuum energy is an underlying background energy that exists in space even when devoid of matter. The vacuum energy is too tiny to have a direct effect on everyday situations. However, it is observed in delicate quantum-mechanical experiments and has consequences for the behavior of the Universe on cosmological scales.

edit In cosmology, dark energy is a hypothetical form of energy which permeates all of space and has strong negative pressure. According to the theory of relativity, the effect of such a negative pressure is qualitatively similar to a force acting in opposition to gravity at large scales. Invoking such an effect is currently the most popular method for explaining the observations of an accelerating universe as well as accounting for a significant portion of the missing mass in the universe. Two prop ...

Wireless energy transfer is the transfer of electromagnetic energy for power to do work via conduction and/or induction without a physical connection. Wireless energy transfer - Description. Wireless energy transfer, by definition, does not require direct electrical conductive contacts. Various systems work by transmitting electromagnetic energy from an external power source through a medium by running a large AC current through an external coil to generate a magnetic flux. The changing magnetic flux induce ...

Neurofeedback (NFB), also called neurotherapy, neurobiofeedback or EEG biofeedback, enables an individual to train brainwave activity, as measured by electrodes on the scalp, via feedback of EEG information in the form of a video display, sound or vibration. If brain activity changes in the direction desired by the therapist, a positive "reward" feedback is given to the individual, and if it regresses, either a negative feedback or no feedback is given (depending on the protocol). Rewards can be as simple as a cha ...

In atomic physics, the Bohr model depicts the atom as a small, positively charged nucleus surrounded by electrons in orbit - similar in structure to the solar system, but with electrostatic forces providing attraction, rather than gravity. Its key success was in explaining the Rydberg formula for the spectral emission lines of atomic hydrogen; while the Rydberg formula had been known experimentally, it did not gain a theoretical underpinning until the Bohr model was introduced. The Bohr model is not a complete model of the atom, and f ...

Panda Energy was founded by current chairman Robert W. Carter in 1982. The creation of the company was a direct result of the passage of the 1978 Public Utility Regulatory Policies Act, which introduced favorable surplus disposal measures for small-scale commercial energy producers. The Carter family have owned a controlling stake in the company ever since, making Panda Energy a family business. After Panda Energy was awarded a RFP to construct a power plant in North Carolina, it expanded throughout the ...

A precursor of this technology can be found in the works of Heinrich Rudolf Hertz in the late nineteenth century. In 1888, Hertz experimented with pulsed power transmission at 500 megacycles per second. As the wireless art developed during the turn of the 20th century, industry was looking toward a method of wireless energy transfer. At the St. Louis World's Fair (1904) a prize was offered for a successful attempt to drive an 0.1 Horsepower air-ship motor by energy transmitted through space at a distance of least 100ft. (The ...
