Diffusion of Technology
The intense usage and utilization of the conventional
strength assets which ends up in increasing challenge of the greenhouse effect
and polluting the environment are forcing engineers and scientists
to expand electricity from non-traditional resources of electricity.
Because of effects of pollutants and international warming there
may be a need for producing energy from renewable assets. The purpose for
generating energy the use of gravity is that it is to be
had all around the Earth, plentiful and consistent too. In this task
we designed a technique in which gravitational energy is similarly amplified in
terms of its significance with the aid of the use of perpetual motion mechanism
and subsequently may be successfully converted into usable electrical energy. The fundamental idea of a gravity power producing
mechanism is simple. Given that all the assets are restrained and
non-particular, this allows to shift the eye toward gravity.
Currently it’s far a dream to meet all power necessities of the sector. But
when we’ve a light that offers loose, clean electricity at the least the simple
requirement of millions of humans may be fulfilled. The vast share of present
answers for warmth and mild in far off, off-grid, regions rely upon bio-mass
(carbon-based totally gasoline sources). issues over ecological impact apart, a
reliance on burning biomass for lights (particularly oil) is high-priced,
keeping millions in gasoline poverty, is dangerous (producing poisonous fumes
and terrible exceptional mild) and dangerous (hearth). Preliminary brief for
‘Carbon-loose Kerosene Lamp’ that led directly on to ‘Gravity light’: The
charity sun aid diagnosed kerosene (used as paraffin) as the foremost, bio-mass
gasoline source burned for lighting fixtures throughout developing African
nations. In addition they identified a few obstacles to the adoption of
alternatives to kerosene that appeared to exist.

Concept for Mechanism of
A suitable mechanism for the working of the gravity light was to be
selected. After considering a number of designs and discarding a few we came up
with three major design concepts which can be used for generating electricity.
Following are the concepts: –
Actuated Gravity Lamp The weight is attached to a rope which is wound
over a pulley whose center consists of a spring which is normally unwound.
The spring is fitted onto a shaft through a slot in the shaft and is wound
over the shaft. The winding of the spring causes the spring to compress under
tension and rotate the shaft along with the winding action. This rotates the
pulley and the weight ascends. After a certain height an initial tension is
given to the spring and the spring starts unwinding slowly at a constant rate
depending on the weight attached to the rope end. The force of the unwinding
force rotates the shaft and helps control the descent rate of the weight.
This shaft would be further connected to a dynamo shaft which will provide us
with the required electricity.
Counter Weight Type Gravity
This employs the use of counter weight principle for lowering the weight
and in turn maintains a control on the descent rate of the falling weight. If
the weight to be lifted is ‘x’ then the counterweight that must be added so
that the weight just stars to descend is ‘x+0.9’. The weight will be attached
to the rope of a pulley and this pulley will be mounted over a shaft which will
be connected to the dynamo shaft producing electricity.
Bicycle Wheel Type Gravity
Light This concept is the most practical one out of the
three and it involves a rim of a bicycle wheel from which a shaft protrudes
supported by bearings and has a sprocket onto which a chain of required pitch
and length is mounted. The weight is mounted on one side of the chain and this
is suspended over the sprocket and lifted by mechanical means to a certain
height. The sprocket is given an initial torque and due to the self-weight and
gravity the weight falls down at a controlled decent rate.
Design and Manufacturing
approach for designing the mount, mechanism for suspending the weight and was
kept as simple as possible.
For 1.5 RPM of sprocket
i.e. for every minute the weight descends down by
Therefore, for 15 minutes: 15*0.375=5.6 meters height
the past history of usage of fuel we came to the conclusion that there is still
tremendous consumption of convention
fuel in the world particularly with developing countries that need makes not only the higher price of fuel but
also pollutes the air which becomes a health hazard later, thus the need of
Gravity fuel was urgent and desirable. The papers shows all the technical
specifications and utility of Gravity lamp in order to provide energy that may
limit the use of fuel to a certain level and understanding. Hence it is assumed
that the energy provided by lamp to be more efficient and this may takes some
more sort of innovation and technological diffusion such that we can generate
the power in higher yield and overcome the capital that is out in buying of the
