TECHNOLOGY FOR USING CONVENTIONAL SOURCES OF ENERGY

IMPROVEMENTS OF THE TECHNOLOGY FOR USING CONVENTIONAL SOURCES OF ENERGY  - 

1)  BIO- MASS -

                 WOOD HAS BEEN USED AS FUEL FOR A LONG TIME . WE CAN INSURE THAT SUFFICIENT TREES ARE PLANTED , A CONTINUOUS FIRE WOOD SUPPLY CAN BE ASSURED. YOU MAST ALSO KNOWN ABOUT A USE OF COW DANG CAKES AS A FUELS . GIVEN THE  LARGE LIVE STOCK POPULATION IN INDIA, THIS CAN ALSO ASSURE US A STUDY FUELS SOURCES . THESE FUELS ARE ANIMALS AND PLANTS PRODUCTS , THE SOURCES OF THESE FUELS ARE CALLED BIO MASS. FUELS DOES NOT GENERATE MUCH HEAT OF BURNING AND A LOT OF SMOKE IS PRODUCTS WHEN THEY ARE BURNT . THE TECHNOLOGICAL INPUTS IN IMPROVE THE EFFICIENCY OF THESE FUELS ARE ESSENTIAL . WHEN WOOD IS BURNT IN LIMITED SUPPLY OF OXYGEN, VOLATILE MATERIALS AND WATER PRESENT IN IT GET REMOVED AND CHARCOAL IS LEFT BEHIND AS RESIDUE. CHARCOAL BURNS WITHOUT FLAMES, IS COMPARATIVELY SMOKELESS AND HAS A HIGHER HEAT PRODUCTION EFFICIENCY.

BIO GAS IS AN EXCELLENT FUEL AS IT HAS UP TO 75% METHANE . IT BURNS  WITHOUT SMOKE AND LEAVES NO REDUCES  SUCH AS ASH IN WOOD , CHARCOAL AND COAL BURNING . ITS HEATING CAPACITY IS VERY HIGH . BIO GAS IS ALSO UTILISED FOR LIGHTNING . THE SLURRY LEFT BEHIND IS REMOVED PERIODICALLY AND CONSUMED AS EXCELLENT MANURE , REACH IN PHOSPHOROUS AND NITROGEN . THE LARGE SCALE UTILISATION OF BIO WASTE AND SEWAGE MATERIAL GIVES US A SAFE AND EFFICIENT METHOD OF WASTE DISPOSAL BESIDES SUPPLYING MANURE AND ENERGY . 

2)  WIND ENERGY -

                         THE KINETIC ENERGY OF THE WIND CAN BE USED TO PERFORM WORK . THIS ENERGY WAS HARNESSED BY WIND MILLS IN THE PAST TO DO ANY MECHANICAL WORK. FOR EX. IN A WATER LIFTING PUMP , THE RATATIONAL MOTION OF WIND MILL IS USED TO LIFT WATER FROM A WELL . TODAY WIND ENERGY IS ALSO PRODUCED ELECTRICITY . THE WIND MILL ESSENTIALLY CONSIST OF A STRUCTURE IDENTICAL TO A LARGE ELECTRIC FAN THAT IS ERECTED AT SOME HEIGHT ON A RIGID OR TOUGH SUPPORT .

TO PRODUCE ELECTRICITY , THE ROTATORY MOTION OF THE WINDMILL IS UTILISED TO TURN THE TURBINE OF THE ELECTRIC GENERATOR OF OUT PUT OF A SINGLE WINDMILL IS QUIT LITTLE CAN NOT BE CONSUMED FROM COMMERCIAL PURPOSES A NUMBER OF WIND MILL ARE ERECTED OVER A LARGE AREA , WHICH IS CALLED WIND ENERGY FARM . THE ENERGY PRODUCTION OF EACH WIND MILL IN A FARM IS COUPLED TOGETHER TO GENERATE ELECTRICITY ON A COMMERCIAL SCALE .
