yet reliable, or while the solar panels of Toyota. This electric car also has disadvantages. Such as, if we have not created real batteries capable of providing sufficient autonomy, the car cannot travel more than 400km. Batteries represent about 40% of the price of the car, you imagine change this battery ? Is it better now changing cars right? The electric car is a great project but will remain in draft form until the oil companies will not stop exercising their power to dominate the automobile

mise en place en 2020 d'une capacité de production électrique à partir de l'énergie solaire d'une capacité totale de 2 000 MW sur cinq sites : Ouarzazate, Ain Bni Mathar, Foum Al Oued, Boujdour et Sebkhat Tah. Les deux technologies - Concentrated Solar Power (CSP) et Photovoltaîque- sont envisagées pour ces différentes stations. Ce programme augmentera la part de l’énergie solaire dans la capacté électrique totale à 14% à l’horizon 2020 et évitera l'émission de 3,7 millions de tonnes de CO² par an.

En mars 2010, quatre nouveaux investisseurs ont annoncé qu'ils s'associaient au projet ; les groupes Enel Green Power (italien), Saint-Gobain Solar (français), Red Electrica de España (espagnol) et Nareva Holding (marocain), ce qui porte à 17 le nombre de partenaires (16 entreprises et la fondation Desertec elle-même). Le projet repose sur le fait qu'un vingtième de la surface

trou », chargé positivement. C’est ce que l’on nomme l’effet photovoltaïque et qui crée une différence de potentiel entre les deux couches. Photocells are constituted with semiconductor materials such as the silicon which transforms directly the solar light in electrical energy. Indeed, photons (particles of light) collide on electrons on the silicon and by this process communicate him their energy. The silicon of the layers of the cell is treated so as to be polarized. To return one of the positive

expensive than its predecessor, taken longer to design, and required an infrastructure of expensive launch facilities, global monitoring stations, mission specialists and research centers. In recent years, however, improvements in electronics, solar power and other technologies have made it possible to shrink satellites dramatically. A new type of satellite, called CubeSat, drastically simplifies and standardizes the design of small spacecraft and brings costs down to less than $100,000 to develop
