In the 19th century, luminiferous aether (or ether), meaning light-bearing aether, was a theorized medium for the propagation of light. James Clerk Maxwell developed a model to explain electric and magnetic phenomena using the aether, a model that led to what are now called Maxwell's equations and the understanding that light is an ...
According to ancient and medieval science, aether (/ ˈ iː θ ər /, alternative spellings include æther, aither, and ether), also known as the fifth element or quintessence, is the material that fills the region of the universe beyond the terrestrial sphere. [1]

The SET rate follows the inverse of the fourth power of the distance [2] = where is the donor emission lifetime; is the distance between donor-acceptor; is the distance at which SET efficiency decreases to 50% (i.e., equal probability of energy transfer and spontaneous emission).
The energy can be in any form in either subsystem, but most energy recovery systems exchange thermal energy in either sensible or latent form. In some circumstances the use of an enabling technology, either daily thermal energy storage or seasonal thermal energy storage (STES, which allows heat or cold storage between opposing seasons), is ...

[7] 100×10 15 grams of carbon/year fixed by photosynthetic organisms, which is equivalent to 4×10 18 kJ/yr = 4×10 21 J/yr of free energy. Cellular respiration is the reverse reaction, wherein energy of plants is taken in and carbon dioxide and water are given off.
Thermal engineering is a specialized sub-discipline of mechanical engineering that deals with the movement of heat energy and transfer. The energy can be transferred between two mediums or transformed into other forms of energy. A thermal engineer will have knowledge of thermodynamics and the process of converting generated energy from thermal ...
