This document discusses utilizing human power as an alternative energy source. It presents several ways human power can be obtained directly through pedal power and bicycle generators or indirectly through gym and playground equipment. Examples are given of a gym that powers itself through stationary bicycles and a children's playground that stores energy from swings and seesaws. Additional devices discussed include a generator added to a revolving door, piezoelectric shoe inserts, and a seesaw design that uses springs and pneumatics to generate electricity. The objectives are to raise awareness of human power, utilize it for various energy needs, and introduce eco-friendly generation devices. Advantages include low-cost and availability while disadvantages note the energy required to sustain human power sources.

1. Utilization of Human Power for
Electric Energy Generation
Guided By: Dr. D. S. Deshmukh
H.O.D Mech. Dept.
Presented By: Mr. Mayur Mohurle
M.E. (1st Year)

2. INTRODUCTION
• The steadily increasing global energy consumption
causes growing numbers of environmental problems.
• This seminar presents the human-powered electric
generators for energy crisis.
• They focus on the use of human power as a renewable
Energy source for consumer products.
• Powered by muscular work from the Human body.

3. OBJECTIVES
• To Aware with Human Power as a Alternate
energy Source
• To Utilize Human Power
• In dependability
• Facilitate to various requirements of energy
• To introduce eco-friendly energy generation
devices

4. Human Power Can be obtained in two
ways:
1. Direct
i. Pedal Power
ii. Bicycle Power Generator
2. Indirect
i. Gym Power
ii. Children Play Instruments

5. 1 ) HUMAN POWER
GYM :
• Power the entire place
with your own energy.
• Opened in the Portland,
Oregon
• As people pedal on
stationary bicycles, a
small motor connected
to the bikes charges
batteries .

6. 2 ) EQUIPMENT AT CHILDREN PLAY
GROUND :
• Seesaw, swing,
and merry-go-round.
• A variety of mechanisms

7. 3) REVOLVING DOOR
:
• A door is equipped with
a special generator
• A set of super capacitors
stores the generated
energy
• Alternative mains
supply
• Energy saving around
4600 kWh per year

8. 4) PIEZO POWERED
SHOE SOLE :
• operate GPS receivers,
location tags and eventually, a
cell phone.
• uses a low-cost polymer
transducer
• Give a power of two mill watts
per shoe on an average walk
• Benefit:
• hikers that need emergency
location devices.
• charge or power other portable
devices such as cell phones
• 3.6 v after 25 steps[5]

9. • power conversion based on
a seesaw.
• Seesaw with hard
cylindrical helical springs
• employ two pneumatic
cylinders.
• bellows-type flexible
sheath between the bottom
of seesaw and the top of the
cylinder.
• Output 24Vdc up to 5A
5) Seesaw: Electric
Generator

10. ADVANTAGES:
• Low-cost and easy availability of electric energy.
• Human Power is a cleaner energy source
• Simplicity of design human powered devices and ease
of maintenance
• As no combustion of fuel takes place so no air
pollution.
• Human powered machines can be manufactured locally.
• Low initial and maintenance cost.
• Self dependent source of energy.
• Best alternative source of energy.

11. DISADVANTAGES:
• The energy costs associated with the
production and delivery of that food and water
must be taken into account when you figure
out the net energy produced.

12. CONCLUSION
• Human power utilization is one of the most useful
techniques which should be utilized for the
human health point of view as well as pollution
produced because of conventional energy
sources.
• The power harnessed can be used as an auxiliary
or back-up source for electricity, especially in
developing countries.
