Introduction

Represents a basic concept of:i. Electric energy harvesting.

ii. Green energy

Project purpose: to generate electricity from energy loss ofvibrating motorized machine.

A concept of vibration is applied in PIZEGE, to transfer thekinetic energy from the vibration to electric energy.

PIZEGE design represents a basic model to harvest thekinetic energy created from the vibrating motorizedmachine which is then transferred and stored as electricenergy.

10% to of the electricity can be saved from the amountgenerated by UTP

Objective

To harvest energy loss from motorized vibrating

machines (Case Study: Compressor)

To save electricity cost by at least 2% per week

(Case study: one wing of lecturers office).

To promote the concept of energy harvesting

Literature Review

Piezo-electric

Piezoelectric element is now widely used to harvest

mechanical energy and convert it to electric energy.

Basically, piezoelectric element produces electric

energy when the material is stressed or pressure is

applied on it. Lead-zirconate-titanate (PZT) is commonly used in

producing this piezoelectric device.

Previous Design

Efficiency:

Amount of Piezo-disk used on previous prototype is

very few and not compatible to use for more Piezo-disk as the current prototype and it is waste of space.

Economic Considerations

Electricity usage at one wing of lecturersoffice (Third floor of each block) based

on Tariff B, Low Voltage Commercial

Tariff.

No Description Value obtained

1 Total penda flour light in one wing = 110 tubes

2 One penda flour bulb produce = 36 W

3 One wing penda flour bulbs produce = 3.96 kW

4 Total working hours in a week = 40 hours

5 Amount of power produced = 158.4 kWh

6 Low voltage commercial tariff = 0.393 RM/kWh

7 Total charged amount for a week = RM62.258 One piezo produce = 0.3 V

9 Total 9 piezo produce = 2.7 V

10 Ratio to commercialize product = 25

11 Commercialized product produce = 67.5 V / 10 A

12 Saved power = 27 kWh

13 Amount saved per week = RM 10.611

14 Percentage saved per week= 17 %

Recommendation


19/23

Recommendation

Use Piezoelectric Energy Harvesting Power

Supply [LTC3588]

Increase amount of Piezo-disk for a larger

scale of machine (e.g. compressor)

Need more sensitive Piezo

Conclusion


21/23

Conclusion

An effective energy harvesting product designto store electricity from kinetic energy.

Efficiently save usage of electricity in UTP by

20%-30% Advantage of PIZEGE:

i. Energy harvesting

ii. Green Technology

iii. Cost-efficient
