Solar cells cadmium sulfide
Cadmium sulfide is a semiconductor that has a very wide band gap of about 2.5 eV, so it is very
absorbent. However, given the possibility of polycrystalline thin films by vacuum evaporation,
this semiconductor is very suitable
It basically consists of the control rods and instrumentation for monitoring different.
The control rods are driven by a series of mechanical, electrical or electronic systems, so as to
ensure rapid extinction of nuclear reactions.
Is constituted by the fuel rods. The core has a geometric shape that is characteristic, cooled by
a fluid, usually water. In some reactor core is located within a pool of water, about 10-12 feet
deep or inside a pressure vessel made of steel
Construction of a dam
To begin two transverse embankments are called cofferdams were constructed. A longitudinal
cofferdam is then constructed. Thus formed an enclosure, which pumps water is extracted. For
the river did not wear the longitudinal cofferdam
Hydraulics: Hydraulic studies the behavior of water. Lately this is replaced by oil in many
industrial applications, but their study the same name.
Electrical circuit: Set of operators together so that allow the passage or circulation of the
Certain materials, called semiconductors have their valence electrons bound to atoms with very
similar to those of photons constituting the sunlight energy. When it strikes the semiconductor its
photons break the bonds and the valence electrons

The immediate arrest of the nuclear reaction.
The permanent cooling of the fuel through an effective system of safeguards.
The existence and integrity of successive physical barriers to ensure confinement of radiation

Energy is an essential concept of science. From a view to define complex material. The most
basic of definitions indicates that is the ability of a body to produce work, ie the amount of
energy contained in the body is measured by the work they are
