Molten salt stores the excessive thermal energy during day and gives it for the power generation during night. I some colder regions, to systems are utilized; atifreeze rust proof liquid is pumped through the flat plate collects or tubular collector to make the system running at low temperatures. Slar geysers are also installed with the evacuated tube collector to collect the hot water during night. Slar thermal is an efficient process to increase the temperature of water. Te system can easily fulfill the need of hot water up to in an efficient manner.
Hwever, te efficiency of the solar thermal process decreases during winters due to the short day hours. Fr the life boat, tese solar absorbers can only be installed to provide hot water for the disinfection and evaporation and condensation. Te size that can be best suit for the life boar should be 2039mm x 1139mm x 80mm with flexible material. Te absorber surface area should be in the range 2.15 square meters to 2.32 square meters. Wnd generators utilize the wind energy to generate electrical Te aerodynamic energy of the wind forces the wind turbine blades to change their position and rotate in a designated direction.
Te turbine rotates in the reaction of the process and turns the alternator that generates the electrical energy. Eectrical energy can be further converted to any other form, lke heat energy or mechanical energy like motors. Te output of the wind generator depends on the capacity of the wind generator and speed of the wind. Wnd generators can give power to several megawatts. Hwever, fr the lifeboat there several disadvantages of the wind energy.
Wnd generators do not come in flexible packages. I installed in life boats for an exception, wnd generators will require scheduled maintenance. Hwever, wnd generators require less maintenance as compared to diesel generators. Te turbine is attached to the shaft that is connected to gearbox. I is due to the fact that wind turbines rotate at quite slow speed and generator required an adequate rotational speed to generate a fixed frequency. Te voltage this is generated by the turbine is fed to a up transformer that increases the voltages for the better transmission and then a transformer situated near our home converts it back to be utilized at home or industry.
Slar Photovoltaic (PV) cells convert solar light energy packed in photons...
