DISADVANTAGESBlow down of towers due to hurricane or
typhoon.High acoustic noise level.Requires energy storage batteries.
Applications of solar powerSpace and water heating in domestic and commercial
buildingsLarge scale heat collection for generation of
electricityDomestic lightingStreet lightingVillage electrificationWater pumpingDesalination of salty waterRailway/traffic signals
FUEL CELLA fuel cell is an electrochemical conversion device. It produces electricity from fuel(on the anode side) and an
oxidant(on the cathode side), which react in the presence of an electrolyte.
A hydrogen fuel cell uses hydrogen as its fuel and oxygen (usually from air) as its oxidant.
An Electrolyte is sandwiched between two electrodes.Oxygen passes through one end and hydrogen from the other
and they electrochemically react to generate electricity, water and heat.
Encouraged by a catalyst, the hydrogen atom splits into proton and electron, which take different paths to cathode.
Proton passes through the electrolyte and electron creates current which can be utilized before it returns to cathode. There it reunites with hydrogen and oxygen to form water
Tidal Power PlantThe tides offer a source of energy because
of the P.E. of the raised tide water or the K.E. of the tidal stream
The water on the earth rises and falls due to changing gravitation force.
Selection Of SiteThe tidal range should be largeThe storage area should be large The site should allow the development of
the necessary plant for reasonable cost
