Abstract: Cuando imagino el universo y toda su dinámica pienso en cuanta energía existe para hacerla posible, y que si existe tanta pues debemos sacarle provecho de alguna forma. Sin ir muy lejos (porque aún no podemos), tenemos al sol, una estrella del tipo enana amarilla que cada segundo produce 3.8x1026J de energía de los cuales 1.75x1017J llegan a la Tierra (equivalente a 1370W/m2 ). Si bien no toda esta energía alcanza a la superficie terrestre, pues parte es reflejada de vuelta al espacio (conocido como albedo terrestre y equivalente al 30% aproximadamente), otra parte es absorbida por las nubes, gases y polvo atmosférico (alrededor del 21%) y otra menor parte absorbida por el ozono (3%), aún nos queda el 46% de la radiación incidente equivalente a 8x1016 J/s (W) que actualmente está calentando la superficie de la tierra, evaporando el agua para hacer posible el ciclo hidrológico, originando los vientos y mareas, y sirviendo en la fotosíntesis.
Conociendo lo anterior, podemos calcular el potencial de energía anual sobre la superficie terrestre (en otra ocasión idearemos algo a instalar en el espacio y así aprovechar el 100% de la irradiación solar), luego de un simple cálculo, obtenemos aproximadamente 7x1020Wh <> 7x108 TWh; pues bien lo interesante aquí es que el consumo eléctrico anual en el mundo es de 23 107 TWh1 , es decir apenas el 0.0033% de la energía que nos provee el sol, creo que definitivamente no alteraremos el equilibrio natural de la naturaleza y de la vida en general por usar ese ínfimo porcentaje de energía.
La intención del presente trabajo es utilizar la energía solar para lo que ya por naturaleza sirve, la iluminación; no limitándose a las horas del día sino también durante la noche, a través de un sistema de generación fotovoltaica que almacene la energía solar durante el día y sea emitida durante la noche en forma de luz.
When I imagine the universe and its entire dynamic, I think about how much energy there is to make it possible, and if there is so much, then we must take advantage of it in some way. Without going too far (because we still can't), we have the sun, a star of the yellow dwarf type that produces 3.8x1026J of energy every second of which 1.75x1017J reach Earth (equivalent to 1370W/m2). While not all of this energy reaches the earth's surface, as part is reflected back into space (known as terrestrial albedo and approximately equivalent to 30%), another part is absorbed by clouds, gases and atmospheric dust (about 21%) and another minor part absorbed by ozone (3%), we still have 46% of the incident radiation equivalent to 8x1016 J/s (W) that is currently heating the surface of the earth, evaporating the water to make possible the hydrological cycle, causing winds and tides, and serving in photosynthesis. Knowing the above, we can calculate the annual energy potential on the earth's surface (on another occasion we will devise something to install in space and thus take advantage of 100% of the solar irradiation), after a simple calculation, we obtain approximately 7x1020Wh <> 7x108 TWh; well, the interesting thing here is that the annual electricity consumption all over the world is 23 107 TWh2, that is to say, only 0.0033% of the energy that the sun provides us, I think that we will definitely not alter the natural balance of nature and life in general for using that tiny percentage of energy. The intention of the present work is to use solar energy for what naturally already serves, lighting; not limiting to the hours of the day but also at night, through a photovoltaic generation system that stores solar energy during the day and emitted it at night in form of light.
