The solar assisted "Intelligent" building-a revolution in the modern low-energy constructions\´ conception

Renewable energies and especially solar energy are not a really new subject. Even in past historical times it seems that this and other natural energy resources were used to produce mechanical or other kind of work. Without entering the mode of usage and the specific appliances, we can note only that ancient people knew really much more about solar energy than we suppose they knew. In past modern times, solar energy was used by August Mouchot to drive a steam engine at the Universal Exposition in Paris in 1878 and Ericsson built a number of solar driven engines, the largest being capable to produce 2.5 kW, between 1875 and 1885. Solar energy is today largely used in developing countries, in arid and isolated areas to produce householding electricity. This will be the fuel of the future. Mankind´s reserves of conventional fuels are close to their red line. We have to think about the energetic future of the coming generations. This future - indubitably - will be a solar one.
