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.
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!
