INTRODUCTION
A major part of world today An
electricity generating playground device configured for recreational activity
by children includes a playground device having a cyclically movable part. An
electricity generator is operable coupled to the cyclically movable part, and
operable to generate electricity when the cyclically movable part is moved
through a cyclical motion. A duty cycle controller is operable coupled to the
electricity generator, and operable to convert a predetermined portion of the kinetic
energy of the cyclically movable part to usable electricity. Human
power conversion is easily achieved from children’s play under conditions where
the children are static relative to the moving playground mechanism, such as
seesaw, swing, and merry-go-round . Where the children are in a dynamic state
relative to a static mechanism (e.g., slide) it will be difficult to employ
cost-effective human power conversion techniques due to considerations of
safety and simplicity.
Energy is the driving force of modern
societies, and generation and utilization of energy are essential for
socioeconomic development. Per-capita energy consumption levels are often
considered a good measure of economic development. In recent years, energy
scarcity has become a serious problem due to depletion of non-renewable energy
sources, increasing population, globalization of energy intensive economic
development, environmental pollution,
and global warming
In
recent years, there have been many interesting developments in the field of
human power conversion. In the present paper, a method of harnessing the power
of children's play in playgrounds and public places, on devices such as the
seesaw, merry-go-round, and swing is proposed.
When large numbers of children play in a
school playground, part of the power of their play can usefully be harnessed
resulting in significant energy storage. This stored energy can then be
converted to electricity for powering basic, low power appliances in the school
such as lights, fans, communications equipment, and so on. The method provides
a low-cost, low-resource means of generation of auxiliary electric power,
especially for use in developing countries.
A major part of world today still
doesn’t have basic lighting facilities or motive power available to draw
water/or run any devices. Energy is getting costlier by the day and power cuts
today are becoming a crude reality even for people living in cities across the
globe. A huge chunk of population living in the so-called rural areas of the world
, due to huge transmission costs will not get electricity in the near future.
Fossil fuels are being burnt for basic lighting in these areas, which create
air pollution, and adding to the already polluted environment.
We propose a new method to solve the
above-mentioned problems for basic lighting and give the required motive power
to drive mechanical loads such as manual marry go round devices or any
machines, which could be run, by the generated motive power by the proposed new
method and device. Our proposed devices made by the new method do not involve
any use of fossil fuel and is simple in
construction and the materials used are
also simple and readily available. Hence the construction and use is very
simple and anyone can use it. The invention can be very useful in providing a
simple method to drive electrical loads or mechanical loads in space ships for
people going on space missions for whom the available power is very limited
which puts a lot of of constraint on these people in their quest to explore and
study the outer space which would further help humans understand the universe
in a better light.
