Problems faced by people today

Lack of petrol

Rising Oil Prices

Waste discharged from the

exhaust pipe is not made

used of properly

Partly caused by disrupts in

the Middle East who is a

major oil producer.

Due to the increasing

number of cars and demand

for it

Our solution: The small turbine that does great thingsMounted 5cm behind the exhaust pipe at

the end of the exhaust pipe to harness the kinetic energy from the exhaust and the wind to generate electricity.

It can be used to power small components such as the window-wiper, lights in the car and the air con blower.

It is light, cheap and efficient.It makes the petrol use more efficient.Even works when the car’s engine is on

but the car is not moving.

Reasons for the location of the turbineAdvantages for a turbine mounted 5cm behind the exhaust pipe:

-get the maximum amount of kinetic energy available from the exhaust pipe and the surrounding wind when the car is driving. (it is tested)-Air around it can cool it and prevent it form overheating.-Will not block the exhaust pipe-Easy to maintain

Colour and material of turbineColourGrey, because: it does not trap too much heatdoes not look too bad when dirtied by the

exhaust.MaterialStainless Steel, because it is light and durablewhen small objects such as stones hit it, it

will not be damaged too badly.

Limitations of the invention

The plan of the invention

CAR

Exhaust Pipe

Dynamo

Battery

Electronic Components

How it worksTurning turbine turns the dynamo which generates electricity to be stored in a separate battery, then the electricity is used by the electronic component.

The prototypeThe invention, when put in the market, will

have different models of it built to suit different types of cars

The battery used in the prototype will be the exact one used in the real invention

The turbine and dynamo will be modified in the actual invention as materials to make it may only be available in factories.

Materials for the prototype cost less than $20, so the real invention should be within $100, an amount affordable as an investment by majority of drivers.

Calculation (Part 1)For example…Air-con blower (Main component in

air conditioner)- Uses 200 Watt motor- Running current about 17 ampere.- About 0.8% of engine power.- Which is about 0.8% of fuel

consumption

Calculations (Part 2)After the calculations, it could be

concluded that:-If every car’s monthly fuel consumption

is 100 litres, 800 millilitres can be saved just by using the invention to power the air-con blower.

- Singapore has about 590 000 cars in 2010, so, if all cars in Singapore use this invention, 427 000 litres of fuel can be saved monthly. (Based on the above condition)

So…

Just by making the invention power the air-con blower, in Singapore, 427 000 litres of fuel can be saved monthly if each car uses 100 litres of fuel per month. Furthermore the invention only costs less than $100, imagine the amount of money and fuel that could be saved!
