Wind mill

Yarn texturizing, throwing, twisting, and winding mills... 

An early wind mill (c. 1430), with an automalic elevator for lilting flour bags. The post was designed to turn in accordance with the direction of the v/lnd. (Corbis Corporation)... 

Wind on land will supply 2.1 TW from saturating the entire class 3 land area with wind mills, according to IPCC estimates. 

MYKONOS wind-mills (see below) the first figure refers to the munt r of atoms within the phosphazenic ring (6 = N3P3, 8 = N P ) and the second figure is connected with the number of atoms within the cyclic amino ligand (3 = Az, 5 = Pyrro). 

Wind mills make use of the kinetic energy of the air molecules, transforming it into mechanical or electrical energy. 

Anemometers (wind mills) have been described as particularly sensitive methods of detecting gas flow in freeze-drier chambers. Such devices cannot, of course, discriminate between different gases. 

Ambient air flow or forced convection can also be a source of energy for distributed environmental sensors or similar autonomous devices exposed to a flow. The airflow can induce the rotation of a microturbine (similar to large-scale wind mills) or the oscillation of a structure. This mechanical energy can then be converted to electricity by electromagnetic, piezoelectric, or electrostatic principles. 

Energy issues are more and more important today. Smart textiles may offer important contributions for energy harvesting and production (flexible photovoltaic cells, wind mills, piezoelectric yams) and for energy storage (super capacitors, flexible batteries). 

Bonded joints are extensively employed in the construction of composite structures in aerospace applications, maritime structures, lifting equipment, wind mills as well as automotive industries [3, 4, 5], Unlike the bolt hole in mechanical fastening that causes a stress concentration in the composite joint plates, adhesively bonded joints minimize the potential for stress concentration within the joint. Besides, applications where lower structural weight, improved damage tolerance design philosophy are required, adhesively bonded joints provides a potential solution. Bonded joints are an efficent fastening solution also for hybrid structures, i.e., structures where composite parts are connected to metal parts. 

Main fluoromaterial applications for the established energy production technologies, PV and wind mill, are listed in Table 17.2. In the following table, only the usage of fluoropolymers in PV will be discussed.

Several aspects must be considered for a comparison of energy sources that generate electricity. The first one is the quantity of carbon dioxide equivalent/kWh rejected by energy sources. Figure 1.3 shows the relationship between the CO2 production and the reaction (response time) for a number of electric power suppliers [11]. It is evident that the response time of nuclear plant (48 h) is bigger than hydro-electric dam or renewable systems such as wind mill and photovoltaic (few seconds). In the middle are the electric power stations using coal, oil or gas.
