cool idea 4 project proposal

Ini merupakan projek yang aku nak cadangkan untuk budak buat pada sem depan. Tapi sem depan aku dah tak ngajar. Maka, sapa-sapa yang berminat boleh la cuba wat projek ni. Cool jugak bende ni. Guna konsep compressed air untuk gerak. Projek ni dah dikomersilkan kat france untuk kereta yang guna compress air. Kalau ada 2, 3 bijik boleh wat race ni..

Abstract

Pipe inspection machine technology or 'Pipe Inspection Machine' is a powerful approach to the examination pipe forward for industrial uses as well as laymen. This project will further enhance the advancement of new technologies to the front. In addition, income pipe product inspection machine makes it easy to find stem work disability pipe channels and can decrease cost product full restore operation and if there have damage system. This pipe inspection machine uses some of the quality technologies in tune with today's progress. Wireless cameras are one of the high-tech components that are classified. Wireless cameras are capable of describing important announcement regarding pipe tract problems as well as using "infrared vision" for imposing damaged. Then, the machine inspection pipe also has a DC motor technology is cooked to follow the character to produce a good electronic circuit. This machine can also follow by setting size pipe and diameter that examined during the running process. In addition, the inspection machine can be used in this piping system that has a cylinder angle pipe

sterling engine

A Stirling engine is a heat engine operating by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work.

Originally conceived in 1816 as an industrial prime mover to rival the steam engine, its practical use was largely confined to low-power domestic applications for over a century

Typical of heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle. The efficiency of the process has an upper limit set by the efficiency of the equivalent Carnot cycle operating between the same hot and cold temperatures.

Like the steam engine, the Stirling engine is traditionally classified as an external combustion engine, as all heat transfers to and from the working fluid take place through a solid boundary (heat exchanger). This contrasts with an internal combustion engine where heat input is by combustion of a fuel within the body of the working fluid. Unlike a steam engine's (or more generally a Rankine cycle engine's) usage of a working fluid in both its liquid and gaseous phases, the Stirling engine encloses a fixed mass of permanently gaseous fluid such as air.

The Stirling engine is noted for its high efficiency compared to steam engines, quiet operation, and the ease with which it can use almost any heat source. This compatibility with alternative and renewable energy sources has become increasingly significant as the price of conventional fuels rises, and also in light of concerns such as peak oil and climate change. This engine is currently exciting interest as the core component of micro combined heat and power (CHP) units, in which it is more efficient and safer than a comparable steam engine.

Apple Computer versus Apple Computer

1.0  Overview

Steve Job was born on 24 February 1955. He was co-founder of Apple Computers with Stephen Wozniak in 1976 when he was only 21. Interesting story about the founded of Apple Computer started in the Job’s family garage and funded by selling his Volkswagen bus and Wozniak sold his beloved scientific calculator. With the selling of first Apple 1 of $666.66, their first model earned them $774,000. Apple II sales made an incredible record of $139 million, 700% increased three years later. By 1980, Apple Computer became a publically traded company worth $1.2 billon on the very first day of trading [1]. This in where John Sculley of PepsiCo join Apple Computer as Apple’s President.
