What is a Hybrid Vehicle?
A hybrid vehicle is an automobile that has two or more major sources of propulsion power.
Most hybrid vehicles currently marketed to consumers have both conventional gasoline and electric motors.
Other power sources may include hydrogen, propane, CNG, and solar energy, wind energy .
INTRODUCTION With volatality in petrol prices and other escalating costs,
private transport system has become a costly affair, but scalingdown fares is a daunting task.
Innovation has answer to all problems.
Efficient use of solar, wind and shock absorber are viable alternatives to cut fares and ensure clean and green environment
We came up with a novel idea of designing a hybrid car powered by solar, wind and shock absorber to support as a power source.
Shock absorberNew shock absorber technology will convert those bumps and potholes into useful energy
INTRODUCTIONThe shock absorber harvests energy from vibrations experienced by a vehicle's suspension system into electricity that can charge the battery and power vehicle electronics
An energy-harvesting shock absorber that can be installed in a vehicle’s suspension system to absorb the energy from bumps in the road, convert the energy into electricity, and improve fuel efficiency by 1-8%
This design of shock absorber is done by David chandler of MIT in 2009. The device consists of two components - a hollow coil assembly and a magnet assembly that uses vibrational energy from the vehicle’s suspension to move up and down inside it.
Design
The magnets are arranged with like-poles of adjacent magnets facing each other to help push the magnetic flux outward. The magnetic assembly is encased in an outer cylinder made of high magnetically permeable material to further increase magnetic flux density in the coils.

SOLAR ENERGY CAR
HOW IT WORK?
COMPONENTS Solar Array
Power Trackers
Batteries
Motor & Controller
SOLAR ARRAY
Collect the energy from the sun and converts it into usable electrical energy.
HOW SOLAR ARRAY CHANGE SUNLIGHT
TO USABLE ENERGY
First thing the solar array collect sunlight together.
When sunlight is collected together. It immediately change the sunlight to electricity.
Next step is to the power tracker.
POWER TRACKERS Power trackers
convert the solar array voltage to the system voltage.
Power tracker role In this step the power
tracker in the car receive the energy from the solar array, and change the energy that it receive to energy that the car can be use.
BATTERIES
The batteries store energy from the power tracker and makes them available for the motor's use.
Use of battery After the power tracker
convert the energy to the energy that is usable for the car, it send to the battery then the battery store the energy.
This energy is send to the motor and controller to make the car run.
MOTOR & CONTROLLER
The motor controller adjusts the amount of energy that flows to the motor to correspond to the throttle.
The motor uses that energy to drive the wheels
HOW SOLAR-POWER CAR RUNS
When the energy is send from the battery to the motor, the motor adjust the amount of energy that flows to the throttle. The motors use the energy that receive to run the wheel.
This is the process how solar car runs
CONCEPT
A wind-powered car converts wind power into electric energy, thereby helping the car to move forward
there’s an intake valve seated on the roof to a mass all the wind needed to power the car.
An alternator connects to the intake valve which converts the kinetic energy to electrical energy.
This electrical energy is connected to a DC battery pack which is the source of power to a controller.
This controller converts the DC voltage to AC three phase voltage with the help of power diodes
WORKING PRINCIPLE
When the car runs to get the most out of the smallest surface we have to use a turbine with a large contact surface. Such turbine will have only one active side.
it would be better to bend the airstream onto the active area like this:
This ornament increases the efficiency of the wind turbine.
