Energizing India

MECHANICAL BRANCH ENERGIZING INDIA “There is a lot of energy around us, we just need to tap it .”Today is an age of energy crisis where we constantly live in the hope of finding new sources of energy to satisfy the continuously increasing need of it .On one hand where our country is moving towards sources like Nuclear energy ,a lot of energy from non conventional sources still remains untapped.

Construction: It has a rack over which a gear is mouthed with the help of a shaft .One end of the shaft is connected to a dynamo with the help of conveyer belt .A foot paddle is installed with spring below it .A crank mechanism is also present. Working: When the feet-paddle is pressed ,the gear moves on the rack and thereby the rotatory motion is transferred to the dynamo with the help of conveyor belt .The rotatory motion is converted to the electrical energy with the help of dynamo .The crank mechanism is used to bring the system back to the initial position.

The system converts: TIDAL ENERGY MECHANICAL ENERGY ELECTRICAL ENERGY

ROTATIONAL ENERGY

History : The attempts to tap the tidal energy have started since 1930.In 2001 an Australian company “AUSTRALIAN ENERGY PVT. LTD.” set up a mechanism to tap the tidal energy with the help of shrouded turbines .In India 10 crores project which would be used to electrify 1.5 lakhs houses in a village of Sunderban delta in West Bengal is the first attempt to tap tidal energy in India .The project is financed by the ministry of nonconventional energy sources of central government and West Bengal state government .The production would start from 2010.

Advantages: • The mechanism shown in our paper presentation can be used for rural electrification in areas of eastern and

•

western ghats ,where the average speed of waves is 3-5 m/sec whereas all the other mechanism require a wave speed of 8-10 m/sec and hence they can be installed only in selected areas like Pacific ocean, Strait of Gibralter etc. It can be used to electrify 1-2 lacs houses.

•

The efficiency is 65% which is greater than that of normal turbines (60%) and shrouded turbines(65%). This mechanism has a very low maintenance cost as compared to any other large scale power generating mechanism. • The cost of setting up the power plant can be recovered in 3 years even if the customer pays Rs.100 per month as fixed energy charges. • The wear and tear of machinery is less. Conclusion: For a developing country like ours, rural electrification is big challenge and this mechanism can serve as a boon for both social and economic development. •
