Smart spring powered generator / Mohd Syahir Abdul Rahman ...[et al.]

Recently, 94.8% of Malaysia’s electricity has been
generated from fossil fuels, which also the main polluters for the
atmosphere in Malaysia. Efforts have been made to generate
electricity via renewable energies, but the percentage is still low.
To overcome this problem, this project proposes a low cost spring
powered electric generator. The spring powered electric
generator model will be constructed with multiple spring
controlled by hydraulic system. The actual system will be
embedded under the road since it needs the pressure of the
vehicles to stretch the spring coil. Pressure exerted by the vehicle’s
weight from the road users will be delivered in the spring by the
hydraulic system and will be stored as spring force. When the
spring is fully stretched it will alert the sensors and will move the
motor. This process will generate electricity continuously for
several hours depends on how many springs have been fully
stretched by the weight of the vehicles. The generated electricity
can be used to power up roadside facilities such as traffic lights,
street lights and public toilets. This can help to cut down the
electricity cost without any pollution to the atmosphere. For this
system, NI myRIO-1900 will be used to control the hydraulic
system and the monitoring system. As for conclusion, this project
will present a model that can generate electricity through spring
force to fulfill the demand of generating electricity through
renewable energy at low cost. A prototype of a new renewable
energy system that produce electricity at low cost have been
designed. DC generator 2 with the gearing system has been
selected for use in this Smart Spring Powered Generator system
based on their best performance and increase the speed of the DC
generator shaft that produce the highest electricity. The higher
speed shaft of the DC generator rotate will increase the output
power of this system. The output power of this project prototype
system is 26mW. For now, the application that can used from this
project prototype are turn ON the LED lamp.
