Design and Development of speed bumps for energy scavenging
Project Area of Specialization Mechanical EngineeringProject SummaryIn the new digital era of innovations and technologies, Energy Scavenging (harvesting) and the development of
such energy scavenging systems are the talks of the town amongst many researchers. Because of the daily rise in
inhabitants and lack of resources, many countries face energy crises problems. To cope with this, there is a dire
need to add eco-friendly, non-conventional, and innovative sources of producing electricity.
The automobile industry is growing massively and manufacturing a vast number of automobiles every
year. Since the number of cars on roads is increasing tremendously, energy scavenging from the motion of
vehicles should be taken into account.
For this, Eco-Friendly Energy Generation (EFEG) Bumps, or Speed Bumps, are introduced. Energy is
produced when a vehicle passes onto the bump via mechanical and electrical assembly. Many researchers have
used crankshaft and roller mechanisms for energy generation, but we will be using the Rack and Pinion
mechanism of its good strength and efficiency, having fewer maintenance requirements. When a vehicle
moves, it presses rack and pinion, which transmits its linear motion into rotational motion to the gear system. The gear system then runs the idle gear, which is used to restrict the motion in flow only. After the idle gear, dc-motor is attached to generate electricity. The output volatage and current can be viewed on serial monitor or on mobile app via esp32 wifi module.
The DC power is set to be used by traffic signals and lighting up the roads via street lights. If a car having 350 kg weight is passed from bump,
we will have 9.5kW power at the output. As we increase choose vehicle with heavy load, the output power will
also increase. This immense power is more than sufficient to light up street light whole day. The extra power can
be stored in batteries to be used in future.
Soon, this mechanism of generating electricity can be advantageous if given serious attetion as thereare
no harmful effects on the environment and are economical. And if it is not taken into account, then lack of energy
sources will give birth to many other catastrophes leaving the whole world into calamities and causalities.
Objectives:
The main objectives of this project are as follows:
i. To design and develop EFEG (Eco-friendly Energy Generation) bumps.
ii. To follow the methods of lean production and develop an economical mechanical system.
iii. To fulfill energy production demand up to some extent.
iv. To use Rack and Pinion mechanism for energy scavenging.
v. To save and utilize the wasted power, kinetic and potential energy of vehicles.
vi. To use alternative energy generation sources to light up street lights and run traffic signals.
vii. To see the results of generated power via wifi on mobile or on serial monitor.
Our project can be implemented on the areas where the ratio of vehicles is high and they move with slow speed. Our project i.e. speed bumps can be implemented on Traffic light signals and Toll tax plazas to light up street lights. Our project prototype can bear a load of motorbikes for now.
Benefits of the ProjectBenefits:
The benefits of our project are as follows:
1. Street lights can be powered using Eco-friendly speed bumps on roads.
2. Power or energy can be produced without harming the environment.
3. Energy demand can be fulfilled upto some extent.
4. A way of producing clean, green electricity and minimizing the shortage of electricity in that particular area
Final Deliverables:
Our project's final deliverable involves an Eco-friendly speed bump that produces electric current and voltages whenever a vehicle passes over it. Once the power is generated it can be viewed on serial monitor or on mobile using esp32 wifi module.
