Spain : A giant in sunlight energy


Pictures taken from BBC.
From the small photovoltaic cells (diodes semiconductors, collectors of sunlight, activators of electrons, that after amplifying them -in series- convert the light in electricity, activating diverse electronic devices of houses and rural mass media), Japon and Germany have passed to build businesses of sun energy of high performance like that of Espenhain/Leipzig (33 500 sun modules, 5 Megawatts, 1800 homes). Espana that itself does not remain behind has just created the first European commercial sunlight energetic head office intending to provide electric energy to all Seville (600 000 inhabitants), the 2013. Although the sunlight companies that operate in Espana (Abengoa and Solucar) employ photovoltaic cells, the news is that they also have a variant one, conformed by 600 mirrors (helióstates, solar receivers), sown in open fields that collect and reflect the sunlight toward the high thing of a tower of concrete 40-floor (115 m.), where impacting on pipes full of water they get vapor (stored in tanks), that moves turbines generating electricity. Michael Geyer of Abengoa says that this system that costs 3 times but that conventional methods, does not contaminate the environment. We parodied to David Shukman of the BBC, imagine the clear Peruvians deserts of Sechura and Nasca, reflecting his sunlight in rainy medium highaltitudes areas generating huge quantities of electricity.

Energia solar, innovadora en España.


De las pequenas células fotovoltaicas (diodos semiconductores, colectores de luz solar, activadores de electrones y que tras amplificarlos -en serie- convierten la luz en electricidad, activando diversos dispositivos electrónicos de casas y medios de comunicación rural), Japón y Alemania han pasado a construir empresas de energia solar de alto rendimiento como la de Espenhain/Leipzig (33 500 modulos solares, 5 Megavatios, 1800 hogares). España que no se queda atrás acaba de crear la primera central energética comercial solar europea pretendiendo proporcionar energia electrica a toda Sevilla (600 000 habitantes), el 2013. Aunque las empresas que operan en Espana (Abengoa y Solucar) emplean células fotovoltaicas, la novedad es que tambien disponen de una variante, conformada por 600 espejos (helióstatos, receptores solares), sembrados en campo abierto que colectan y reflejan la luz solar hacia lo alto de una torre de concreto de 40 pisos (115 m.), donde incidiendo sobre pipas llenas de agua la convierten en vapor (almacenado en tanques), que mueve turbinas generando electricidad. Michael Geyer de Abengoa dice que este sistema que cuesta 3 veces mas que los metodos convencionales, no contamina el medio ambiente. Parodiando a David Shukman de la BBC, imaginamos los limpidos desiertos peruanos de Sechura y Nasca, reflejando su luz solar en areas lluviosas medioaltoandinas generando ingentes cantidades de electricidad.
