The Problem
We want to create a multi-cylinder Stirling Engine for little to no money at all with the help of a CAD design using free software off the internet. We want the design to be simple but effective and easy for anyone to replicate.

Task1
The goal for week one is to start with a CAD design and then determine the materials needed to create the Stiriling Engine we want.

Week1 Activities
Was absent from class due to surgery, but still got work done. finished first proto-type sterling engine. gather materials for next engine. Rationalize differences

Week1 Narrative
I was out during the first week due to foot surgery. But I was still able to complete the first proto-type engine. It was a failure. so I went back to the drawing board and started to design another engine model. This time instead of using a soda can, I would use a tin can as my compression chamber so it took heat better and instead of soldering rods I'd either use a close hanger or welding rod. The displacer and power piston will be made from styrfoam and wrapped around with aluminum foil.

Week1 Peer Review
Go to each team mates weekly summary wiki page. Read their activities and narrative. Then go the associated discussion page. Say something positive on this page. Try some constructive criticism. Add your name and a signature ~ by entering four tildes in a row to create a time and date stamp. Create a new category if another team mate has already commented here.

Assign Task2
Get the new sterling engine almost complete and drill a hole into the compression chamber to be able to add the pvc piping for the power piston chamber. Also I have to find a way to re-seal the cans so i have the best compression possible. Bend the close hanger and welders rod to work with the displacer and power piston.

Week2 Activities
I came up with a new design for a sterling engine out of tin cans, welders rod, rubber bands, pvc piping, rubber sealant,and styrfoam. building is a challenge because in my last engine the piston and displacer did not move well. In the new engine there is a separate chamber for both components. the hardest part looking at the model right now is putting the power piston chamber into the displacers chamber and making sure it doesn't vibrate out. Rationalize differences

Week2 Narrative
The engine still has not wanted to work. I can see it wants to move. the engine shakes around alot when in motion. This could be the problem why it doesnt want to go all the way. I wont scrap this engine because it was more succesful than the other sterling engine.

Assign Task3
Bring in a semi working sterling engine and start to build one very good working sterling engine. workout small mistakes in the new engine

Week3 Activities
My teammate brought in a different displacer chamber for me. he made two of them. i filled out my notebook and stated that making the crank shaft and getting the precise measurments would be hard. Rationalize differences

Week3 Narrative
took home the new displacer chamber and tried to create a new sterling engine. the engine is still being built but has so many problems. the crank shaft is to weak and the offset gears are out of whack. getting the power piston and pvc piping will take some time. i started to gather some more materials lying around in the house.

Assign Task4
Build new sterling engine over the weekend.

Compare actual work done to Task4
Rationalize differences

Week4 Narrative
Upload photos to wikimedia. Upload video to youtube. Convert all spreadsheets, documents, and presentations to wiki format and create wiki subpage of your page for each of them. Link to them here in a narrative that tells a story. High light the problems (engineering problems) you had and how you solved them.
