Cars
By Irfan, Sonny & Jack E
What Are Cars ?
What are Cars?
Most people know what cars are, but to give a brief description, cars are a private form of transport in which multiple people can be seated, and the parts of them work interdependently, with the engine sytem at the heart.
Most of the people around the world know what cars are, but to give a brief description, cars are a general form of private transportation in which multiple people can travel relatively safely.

There are other automobiles that share the relatively same system as cars. These are:
Trucks
Limousines (Stretch cars)
Motorbikes
How do cars work ?
How cars work
At the heart of the car is the engine.
How is energy used and made for cars ?
There are three types of energy that are used to power cars. These are diesel, petroleum and electricity. There are very few electric cars, and one of those brands are Tesla. There are also a handful of hybrid cars, which possess the option to switch between electricity and petrol. A brand which produces hybrid cars is Toyota, and the model is the Camry Hybrid. The main diesel cars are 4x4 cars.
Interdependent systems
Cars function with the aid of a vast array of components, and when one of them corrupts, the car breaks down. When the key is turned, the battery kick starts the engine, the fuel injectors spray the petrol or diesel into the engine, and the spark plug lights the petrol. In turn, the crankshaft spins the shaft connected to the rear wheels, the front axle spins the side axle, and then the car starts moving.
Electricity can be made using a variety of techniques.
People derive solar power from the solar panels
situated on the roof of their house. It derives energy from the sun, utilising all the technology in the panels so that it will transform the suns solar rays efficiently into power for your family to use everyday. Solar panels also store electricity as a back-up.
Solar Power
How do solar panels work ?
How is Electricity Made ?
The main process of generating solar electricity is this:
The sun’s rays hit the solar cells and heat them up
This causes an atomic reaction which generates electricity.
This solar power goes to the inverter where it is converted to AC current that can be implemented throughout the house and sold back to the power companies.
There are two types of common electricity.
Current Electricity

Current is the rate of flow of electrons. It is produced by moving electrons and it is measured in amperes. Unlike static electricity, current electricity need to flow through a conductor, usually copper wire. Current with electricity is just like current when you think of a river. The river flows from one spot to another, and the speed it moves is the speed of the current. With electricity, current is a measure of the amount of energy transferred over a period of time. That energy is called a flow of electrons. One of the results of current is the heating of the conductor. When an electric stove heats up, it's because of the flow of current.
Static electricity is created when electrical charges build up on the surface of a material or object. It is usually caused by rubbing materials against each other. The result of this build-up of static electricity is that objects may be attracted to each other or may even cause a spark to jump from one to the other. For example rub a balloon on a piece of wool and hold it up to the wall.
All materials have a neutral charge before rubbing, and that's because of the equal number of subatomic protons and electrons. After rubbing, the different objects become either positivel or negatively charged.
Static Electricity
- Subatomic = smaller than an atom
- Electrons = negatively charged particles
- Protons = positively charged particles
Solar Cells
A solar panel is composed of many solar cells.
(Photovoltaic cells)
The job of these cells is to convert photons from the Sun into electrons, and therefore creates electricity.
Solar Cell
Nuclear Power
The process of making nuclear power is this:
First,
The reactor has a bundle of uranium.
The control rods are lifted,
increasing the rate of the nuclear reaction
The steam spins the turbines
And generates electricity.
Utilising Nuclear power can be nationally risky.
This is because
There is the risk of a nuclear meltdown occurring, wreaking widespread destruction and death, and long term effects like disease from the radiation.
Hydroelectricity
Hydroelectricity is made by running reservoir water into a turbine which is connected to a generator, and thus, electricity is available.

How is it made ?
Firstly, gates connected to the dam open and let water into the penstock, the pipe that connects the dam to the turbine.
Then, the force of the rushing water turns the blades the turbine, which is connected to the electrical generator.
Wind Power
How is Petrol Produced ?
Geothermal Energy
How is it made ?
Geothermal energy is made when cold water is passed through heated rocks below the Earth's surface, and is retrieved as steaming water which turns a fan which is connected to the electrical generator.
Wind Power
Electricity from wind is made when wind spins a large wind turbine, which, in turn, is connected to an electrical generator.
How is Diesel Produced ?
Petrol is made by boiling crude oil, and this seperates it into its elements. Petrol is collected from the elements with the lowest boiling points.
Diesel is made by seperating crude oil into its components, and collecting them.

Most efficient power sources
The most efficient general power source is commercial nuclear power because it releases little waste and produces a very large amount of power compared to other power sources.
When it comes to automobiles, the most efficient power source is Compressed Air Technology (CAT). This combines a compressed air engine and very little fuel, making it possible to run at least 2000 km with zero pollution.

Awesome Car Fact:
Can cars be "grown?"
The Mercedes-Benz BIOME concept is predicted to be virtually grown in a lab. The Mercedes-Benz signs on the front and back of the BIOME will have DNA encoded into them, and this will be used to cultivate seeds that grow into the body and internal systems of the car. The wheels will be grown from seperate seeds. It will run on BioNectar4534 ,and this is stored in the car's BioFibre, which is what the exterior of the car is made of.

Wind Power
Electricity from wind is made when wind spins a large wind turbine, which, in turn, is connected to an electrical generator.
The piston starts at the top, the intake valve opens, and the piston moves down to let the engine take in a cylinder-full of air and gasoline. This is the intake stroke. Only the tiniest drop of gasoline needs to be mixed into the air for this to work.

Then the piston moves back up to compress this fuel/air mixture. Compression makes the explosion more powerful.
When the piston reaches the top of its stroke, the spark plug emits a spark to ignite the gasoline. The gasoline charge in the cylinder explodes, driving the piston down.
Once the piston hits the bottom of its stroke, the exhaust valve opens and the exhaust exits the cylinder to go out the tailpipe.
