Tidal stream generators (TSGs) make use of the kinetic energy of moving water to power turbines, in a similar way to windturbines that use moving air.
A TSG is a machine that extracts energy from moving masses of water, or tides.
Energy can be captured from tidal streams using two methods,
Tidal fences and Tidal turbines.
Dynamic tidal power or DTP is a new an

system. The achievement of this basic goal of a modern security operation requires the commitment and cooperation of central and local government agencies, airport authorities, airlines, other airport tenants, police and security staff, and the public itself. We will discuss how security procedures affect airport operation and describes in general terms airport security requirements. For obvious
What is Bioenergy?
Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.
So, Why do we produce Bioenergy?
One reason governments

systematic problems. Only in this way, by employing an analytical approach, can a security system's strengths and weaknesses be evaluated. Alterations in major policy direction are by a continuous situation assessment of the changing security climate. Factors that can radically alter the security threat in a particular country or at a particular airport are political agitation or unrest and wides
systems combine a coal gasification unit with a gas fired combined cycle power generation unit. The first stage is the coal gasification process as mentioned above. The second stage takes the cleaned gas and burns it in a conventional gas turbine to produce electrical energy, and the hot exhaust gas is recovered and used to boil water, creating steam for a steam turbine which also produces electr
