1Light-dependent reaction — The initial stage of the photosynthetic system is the light dependent reaction, which converts solar energy into potential energy. The light dependent reaction produces oxygen gas and converts ADP and NADP+ intothe energy carriers ATP and… …
2optical pumping — Physics, Optics. a method for increasing the number of atoms or molecules occupying higher energy levels by irradiating them with light of the proper frequencies to raise them to those levels. [1950 55] * * * optical pumping noun (physics) The… …
3Laser pumping — is the act of energy transfer from an external source into the gain medium of a laser. The energy is absorbed in the medium, producing excited states in its atoms. When the number of particles in one excited state exceeds the number of particles… …

5Intermittent power source — [ Erie Shores Wind Farm monthly output over a two year period] An intermittent power source is a source of electric power generation that may be uncontrollably variable or more intermittent than conventional power sources, and therefore non… …
6East Kent Light Railway — The East Kent Light Railway was part of the Colonel Stephens group of cheaply built rural light railways in England. Holman Fred Stephens was engineer from its inception, subsequently becoming director and manager. The line ran from Shepherdswell …
7Intermittent energy source — An intermittent energy source is any source of energy that is not continuously available due to some factor outside direct control. The intermittent source may be quite predictable, for example, tidal power, but cannot be dispatched to meet the… …
