ELECTRICITY

GENERATION FROM

STAIRCASES



WHY RENEWABLESOURCES OF ENERGY??

Zero pollution Forever No !inten!n"e



WHY STAIRCASES??•A 150-lb person burns 91 calories for every 10

minutes of stair climbing.

•Also, climbing staircases reduces the need for

escalators and elevators, thus reducing power usage.

•Increases bowel-movement.

•his pro!ect adds to the benefits as it generates power

from climbing staircases.



THE MECHANISM•"tepping and pushing on the stairs to push

ourselves up converts our mechanical energy in the

muscles into gravitational potential energy.

•his gravitational potential energy is then

converted into #inetic energy of motion as the

person is pulled by gravity. his #inetic energy is

ne$t converted into rotational energy and finally

into electrical energy.



WOR#ING "AI% &A"' "'( ()*'% +''%A)%&onverters basically new concept of non-conventional

energy generation. It is electro-mechanical energy

generating machine. his machine converts reciprocating

motion in to rotary motion. he rotational power is storedin flywheel flywheel rotates dynamo, which generates

electricity.

ere first important point is how we get reciprocating

motion, which is prime input in the system. /or that we use

weight of stepping person on the stair case step that climbsor get down the over the overhead bridges.



Contd...

*e put our machine underneath the stair caseinstalling different units below every step foot

space. 'ach person stepping on the every foot step

will press the individual unit separately. All the

units are connected to the common shaft using chainand sproc#et drive. /or stepping moment only the

energy is generated and for that instant sproc#et

wheel will rotate the common shaft summing up the

rotating motion altogether.

F,W.EE,

/lywheel is used to store and convert the

#inetic energy into rotational energy. he

/lywheel which we are using is of 2

inches in diameter and 2mm in thic#ness

of mild steel weighted appro$ 3.3 #g.



/EARS:-

he gears used in our pro!ect is of

mild steel and the shaft on which

the gears are mounted is of cast

iron. he %ac# is of 19mm wideand 2 inches long. It is a vertical

and has suare cross section.



SETUP:-The setup is used to convert thetranslatory motion into rotationalmotion by using rack and pinion,sprocket and chain and a gear.The pinion and the gear is

mounted on a common shaft andthe gear is connected to thefreewheel by the help of the chainmechanism . The use of thefreewheel is that it controls the

reverse motion of the gear whenthe springs are released.



E$%EN&ITURES•A step would cost 4 for the bicycle dynamo and 41 for

other items such as spring, manufacturing cost etcetera.

•6etween 3 floors of a building, there would be 13 floors

averagely.

•otal cost per floor would estimate to 470



POWER OUTPUT

•he 4 bicycle dynamo specified produces a power

output of 3 * when a cyclist drives at around 15 #m8h

m8s.

•"imple calculations show that the dynamo should

ma#e one full revolution in one second.

•/or the previously specified 13 steps as an average, afloor would produce 3 * when a person climbs it.



%LACES OF A%%LICATION

RAILWA



FUTURE AS%ECTSIn future aspects we can use this principal in the speed brea#ers at high ways where are rushes of the vehiclestoo much thus increase input torue and ultimate output

of generator. If we are used this pro!ect at very busystairs palace then we produce efficient useful electricalfor large purposes. his source of power can be used at the station building, platform and waiting rooms. Also by accumulating this

low intensity electricity in 6atteries, it can be supplied tothe commercial comple$es or shopping comple$es near by the railway station or in big villages or in townswhere there is scarcity of electric supply.



SUMMARY•'lectricity generation from staircases will not only

support tremendous generation of electricity, but also

contribute to the fitness of the individual.

•It will also reduce the electricity consumption in the

form of escalators and elevators.

•he cost per floor is !ust 470 and one can generate

enough electricity to compensate the initial costs

uic#ly.
