1. Generation of Electrical Power using Bicycle Pedal
It is known that the supplies of fossil fuels are
limited and their utilization as energy source causes
environmental degradation due to unfinished ignition when
used as energy source, in addition to this as the world
population increase the order for energy sources increases,
so the issue of a steady replacement of fossil fuels with
renewable energy source is of major consideration for most
countries. Renewable power generation system is currently
preferred for clean power generation. With ongoing
revolution in the generation, electricity is generated at
small level by using bicycle pedal. Bicycle is the main mode
of transportation for many Indian villagers. Most of these
villages are un-electrified.
Power generated by pedaling can
be converted from mechanical to electrical energy by using
either dynamo or alternator.

2. Perpetual Motion Machine
Ever since the first century A.D. there have been relative descriptions of known devices as well as manufactures for the
creation of perpetual motion machines. Although physics has led, with two thermodynamic laws, to the opinion
that a
perpetual motion machine is impossible to be manufactured, inventors of every age and educational level appear to claim
that they have invented something «entirely new» or they have improved somebody else’s invention, which «will
function henceforth perpetually»! However the fact of the failure in manufacturing a perpetual motion machine till now,
it does not mean that countless historical elements for these fictional machines become indifferent. The discussion on
every version of a perpetual motion machine on the one hand gives the chance to
comprehend the inventor’s of each
period level of knowledge and his way of thinking, and on the other hand, to locate the points where this «perpetual
motion machine» clashes with the laws of nature and that’s why it is impossible to have been manufactured or have
functioned. The presentation of a new «perpetual motion machine» has excited our interest to locate its weak points.
According to the designer of it the machine functions with the work produced by the buoyant force

3. Hydrolectric Power
Hydroelectric Power is a form of energy a renewable resource. Hydropower provides about 96 percent of the
renewable energy in the United States. Other renewable resources include geothermal, wave
power, tidal power, wind power, and solar power. Hydroelectric powerplants do not use up
resources to create electricity nor do they pollute the air, land, or water, as other powerplants
may.
Hydroelectric power has played an important part in the development of this Nation's
electric power industry. Both small and large hydroelectric power developments were
instrumental in the early expansion of the electric power industry.
Hydroelectric power comes from
flowing water winter and spring runoff from mountain streams and clear lakes.
Water, when it is falling by the force of gravity, can be used to turn turbines
and generators that produce electricity. Objectives Define the term hydroelectric power to
identify the use importance of this energy source To explain the process of
harnessing hydroelectric energy To view and explain a diagram of the
hydroelectric plant To discuss the environmental impacts associated with this
energy source. Hydroelectric Energy Hydroelectric power, or hydroelectricity,
is generated by the force of falling water. Or It is the water that is stored
behind a dam/ reservoirs that can be used to generate electricity.
