Foot steps generator

Introduction

Due to of the cost of the very large the Haram , our project has found a solution to reduce part of the energy that is generated during the density of people and the most populated place in the world without interruption is the rotation around the Kaaba where people are constantly rotate around it.

• we chose that power generate through walking steps on the boards through pedestrian pressure.
• This generator is considered one of the best generators that can be used on this location for many pedestrians.

How the device works?

-This electrical energy will be storing in the 12v rechargeable battery connected to inverter.

-We are using conventional battery charging unit also for giving supply to the circuitry.

-This inverter is used to convert the 12 Volt D.C to the 230 Volt A.C. This 230 Volt A.C voltage is used to activate the loads and

-By using this AC voltage we can operate AC loads

- if we walk on the device continuously we can generate 5 W / h

-Installation of these plates around the Kaaba

-The basic working principle of our project is based on the piezoelectric sensor

- To implement this we adjust the wooden plates above and below the sensors and moveable springs.

-Non-conventional energy using foot step is converting mechanical energy into the

electrical energy

-Foot step board it consist of a 16 piezo electric sensors which are connected in parallel.

-When the pressure is applied on the sensors, the sensors will convert mechanical energy into electrical energy.

• Length of Kaaba is 12 m
• Area of Kaaba is 144 m
• Area of orbit around the Kaaba is 3107 m
• Length of plate is 0.5 cm
• Area of plate 0.25 cm

- Due to decrease and increase in the number of people during the year..

- the orbit was divided into three parts..

the first part

the second part

the third part

Power generated each part:

-In the first period of the year, 1-4 months, people occupy only the first part.

Power generated each part:

first part : 2880h * 3492 plates * 5w/h = 50 MW

-In the first period of the year, 1-4 months, people occupy only the first part.

-In the second period of the year , 5-8 month, people occupy the near and second part.

Power generated each part:

first part : 2880h * 3492 plates * 5w/h = 50 MW

second part : 2880h * ( 3492 plates + 3784 plates )* 5w/h = 105 MW

-In the first period of the year, 1-4 months, people occupy only the first part.

-In the second period of the year , 5-8 month, people occupy the near and second part.

-In the third period of the year 9-12 months, people occupy all parts.

Power generated each part:

first part : 2880h * 3492 plates * 5w/h = 50 MW

second part : 2880h * ( 3492 plates + 3784 plates )* 5w/h = 105 MW

third part : 2880h * ( 3492 plates+3784 plates+5008 plates ) * 5w/h = 177 MW

Total power generated each year is 332 MW

• Pricing of the Haram : 0.32 SR . KW/h

• Pricing of the year:( 0.32 SR KW/h ) * ( 8640 h.year ) =120,062.5 SR .KW

• If we assume the life span of the plates is 10 year .

the pricing of the Haram in 10 year :

( 10 year ) * ( 120,062.5 SR.KW ) = 1,200,625 SR.KW

• Total number of plates = 12,284 plates

• Price of the plates : ( 1,200,625 SR.KW ) / (12,284 plates ) = 98 SR

If the value of one painting > 98 SR , This project is Unsuccessful

If the value of one painting < 98 SR , This project is successful

Advantages and Disadvantages

-Only applicable for the particular place.

-Initial cost of this arrangement is high.

-power generation is simply walking on step.

-No need fuel input.

-This is a Non-conventional system.

-No moving parts -long service life.

-Self-generating -no external power required.

-Compact yet highly sensitive.

-Reliable, Economical, Eco-Friendly.

-Less consumption of Non-renewable energies.

-Power also generated by running or exercising on the step.

-Battery is used to store the generated power.
