Solar power : INTRODUCTION : BEN Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on earth. Only a minuscule fraction of the available solar energy is used. Solar powered electrical generation relies on heat engines and photovoltaics

named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. They are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (the feed water). [edit] HistoryThe first successful design of economizer was used to increase the steam-raising efficiency of the boilers of stationary steam

know how much energy they use and waste. Green IT/computing can increase people’s knowledge and help to save the planet. First, in this paper, I’m going to define Green Information Technology and trying to understand its goals. Then, I want to emphasize, through some observations and significant figures, why it’s important to head for a Green computing way. Afterwards, I’m going to focus on the origin of green IT through the definition, the history and the results of the Energy Star Label. Finally

première entraînera les vols civils supersoniques dont le Concorde et Tupolev Tu-144 sont les symboles. Depuis ces années-là l’avion n’a cessé d’évoluer c’est en 2010, qu’un projet des temps moderne fut réaliser à l’aide d’un avion.En effet, Le projet Solar Impulse initié en Suisse a pour objectif la conception d'un avion solaire, donc à propulsion sans carburant. Lorsque le prototype HB-SIA a accompli son premier vol de nuit (sur une période de 26 heures), l'idée de voir un jour voler un avion commercial

modèle ne sont aujourd’hui pas assez attractives pour assurer un succès commercial. (Photo solar impulse) Il existe aussi l’avion Solar Impulse. L’objectif est de faire voler de nuit comme de jour, sans carburant ni émissions polluantes, un avion monoplace hightech à propulsion électrique alimentée uniquement par l'énergie solaire. Bertrand Piccard et André Borschberg ont pour projet d’amener solar impulse à effectuer prochainement un tour du monde. Les 12 000 cellules photovoltaïques en silicium
