Download as PPT, PDF39 likes24,937 views
This document proposes generating electricity from speed breakers. It discusses using the kinetic energy from vehicles passing over speed bumps to power an electric generator via various mechanisms. The scope is to produce low-cost electricity at locations with traffic. Construction details and the basic principle of converting mechanical to electrical energy are provided. Challenges in initial experiments and achieving proper balance are also noted. While output was low, the concept was demonstrated. Future scopes include designs for heavier vehicles and more efficient mechanisms.

- 2. OVERVIEWOVERVIEW Introduction Scope ,merit and use Construction details. Basic principle. Challenges faced. Future scopes.
- 3. Introduction:Introduction: Is anyone happy with current situation of electricity in India??? So, this is our small step to try to improve this situation by our project. First of all what does electricity mean to us??? Electricity- secondary source of energy i.e. converted from other sources. We need it for every small thing, still notice it’s importance only during load shedding.
- 4. Scope, Merits and UsesScope, Merits and Uses Low Budget electricity production Less floor area No obstruction to traffic Easy maintenance Suitable at parking of multiplexes, malls, toll booths, signals, etc. Uses: Charging batteries and using them to light up the streets, etc.
- 5. Construction details:Construction details: Initial experiments- DC motor as Generator(electric dynamo). Spur gears Flywheel Shaft. Springs bearings
- 7. BASIC PRINCIPLE:BASIC PRINCIPLE: Simple energy conversion from Mechanical to Electrical. To generate electricity using the vehicle weight (potential energy) as input Possible using 3 different mechanisms: I. Crank-shaft mechanism II.Roller mechanism III.Rack- Pinion mechanism
- 8. Crank shaft machanismCrank shaft machanism
- 9. Crank shaft machanismCrank shaft machanism Crank-shafts are required to be mounted on bearings which creates balancing problem leading to mechanical vibrations which in turn damage the bearings. Secondly as bearings are of sliding type, any occurrence of variable load( which is bit obvious in case of vehicles!!) leads to balancing problem.
- 11. Roller mechanism has some different disadvantages. Maintenance will be very difficult Might cause collision.
- 12. Rack and pinion machanismRack and pinion machanism
- 13. Rack-Pinion assembly gives good mounting convenience Maximum gear losses– 3 to 5% Efficiency– 95%
- 14. Challenges we faced!!Challenges we faced!! Selecting suitable generator. Selection of springs. Achieving proper balance of speed and torque.
- 15. What we achieved???What we achieved??? Constructed our own generator by applying the basic principle. Although we got less electrical output, we have successfully explained our idea of generating electricity from speed breaker.
- 16. Future Scope:Future Scope: Such speed breakers can be designed for heavy vehicles, thus increasing input torque and ultimately output of generator. More suitable and compact mechanisms to enhance efficiency.
