CONCEIVING AND ENGINEERING SYSTEMS

Problem Statement
Build a working Stirling engine from the cheapest materials possible. An engine that runs on the base of heat, where air(heat & cold) plays a very significant role in make the engine run.

Setting System Goals and Requirements
The first goal is to make it from the cheapest materials, and they are:
 * Tin
 * 1) Wire wool
 * 2) Steel/copper wire
 * 3) Glue
 * 4) Compact Disc(fly wheel)
 * 5) Temperature-resistant silicone.

The second goal was to decide the size of the engine, because with the size of the outside engine, the size of the inside piston, crank shaft and the connecting link rod changes. The size of the Stirling engine is set as follow: height = 10inches by width = 4inches. There are certain tools that are required in order to make this happen, some of the most commons ones are drill machine, electric cutting tool, plier, tin opener, cutter, scissor.

Defining Function and Concept
The engine uses air which is continually heated and cooled and in order to make this cycle happen is a displace which moves the air up&down constraining the air to move around inside the engine. When the air is heated it amplifies which then pushes the displacer upward. When the cranks turns, it also moves displacer down and the air which is on the top gets cool down which shrikes once again causing the piston go do back down. The whole process keeps on repeating.

Next Steps

 * 1) The first and most significant step will be the air leak from the side of the connecting link rod and the upper chamber.
 * 2) The second step is to increase the size of the lower chamber.
 * 3) The final step is going to be customizing a stand so that the candle or any other heat source could get sufficient amount of oxygen.
