Putt Putt Boat
The year is 2068 and there has been a total shut down of power - gas and electricity. As a result many forms of normal transportation have become obsolete. The government has asked the public for help in the development of transporting vehicle that can only use steam power. Since you are from Newfoundland then you figured it would be best to use something that can be used on the water. The government has suggested that steam power be used because it is cheap and will not require the need for electricity. Another stipulation that the government has is that the device prototype can only be made of recyclable materials. You wonder at what such an opportunity will have for you as you gaze around your garage scanning for the materials that you might use to develop the ideas brewing in your head. You note some plastic pop bottles, candles, and duct tape. This is perhaps all that you will need in order to create your one -of-a-kind steam powered boat.
Step one - Identifying the problem - need to make a steam boat.
Step one - Identifying the problem - need to make a steam boat.
Step two - design brief- make a putt putt boat using a pop bottle and copper tubing. We will need a pop can, copper tubing, popsicle sticks, cardboard, glue sticks, candles, and duct tape. We need a glue gun, pliers, and scissors, utility knife, a binder clip, and aluminum foal.
Step three - Investigation and research - a boat with a very simple steam engine without moving parts, typically powered by a candle or vegetable oil burner.

Step four - Generating alternative solutions - we have come up with three ideas
1. matt: my idea is to make a boat out of Styrofoam and have a peace of 1/2 inch copper tube with a cork one both sides and a peace of 1/8 copper tube going throw the boat
2. going to take a coke can, cut it in half put two holes in the bottom of it, run two straws threw them, and then have the straws connected to 1/2 inch copper pipe with a candle under it to heat it up.
3.milk carton cut in to with a can folded into a square so all sides are sealed and it has two straws running through the bottom of the boat. In the can there's some water and under the can there's a candle which heats up the can which heats up the water to create the steam. oh and there's a stripe in the middle to make it go FASTER!(bay logic)

Step five - choosing a solution.
Questions
1. Is the design practical? 2. Will the design cost a lot of money? 3. Is the design reliable? 4. Is the design durable? 5. Is the design visually appealing? 6. In the design safe? 7. Are the resources available? 8. Are the tools available? 9. Can the design be created on time? 10. Does the solution meet the needs? Total: |
Drawing #1

We chose idea #1 because it has the best total and the highest numbers to be efficient. The materials are cheap and easy to find.
Step six - developing a solution.
Step seven - Testing and evaluating your prototype
