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.

OBJECTIVES:OBJECTIVES:
“Shaping Imagination”“Electricity”-Need of the hour

Scope, Merits and UsesScope, Merits and UsesLow Budget electricity productionLess floor areaNo obstruction to trafficEasy maintenanceSuitable at parking of multiplexes,
malls, toll booths, signals, etc.Uses: Charging batteries and using
them to light up the streets, etc.

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 mechanismII.Roller mechanismIII.Rack- Pinion mechanism

Why Rack- Pinion Why Rack- Pinion mechanism??mechanism??
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.

Roller mechanism has some different disadvantages.
Maintenance will be very difficultMight cause collision.

What we did???
Rack-Pinion assembly gives good mounting convenience
Maximum gear losses– 3 to 5%Efficiency– 95%

Construction of Construction of generator:generator:Initial experiments- DC motor as
GeneratorHow is electricity generated???Basic principle of generation of
electricity.What we did???

Challenges we faced!!Challenges we faced!!Selecting suitable generator.Selection of springs.Achieving proper balance of
speed and torque.

What we achieved???What we achieved???We LEARNT a lot.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.

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.
