9. Electrical Safety Considerations Need to cover the wires. Put a switch to control the circuit.

10. Mechanical Safety Considerations Needs to cover the motor to avoid contact with water. Needs to tide the motor to propeller.

11. Passenger Transport Area The passenger area was an egg dozen cab. The cab was closed to safe the egg when its travel.

12. Main Challenges Put the motor to work only with the solar cell. The solar cell generate too little current. And the most difficult was the board that cracked with the heat and the silicone, and we need to put the solar cell direct to the motor. We have a control to move the boat but not work without the board.

13. Team Overview The project was a good way to bring the tools that we learned on class. The team was perfect, and all the students work hard to do this project. This was an excellent experience to work in group.

14. Project Overview We know this project was one of the best project of this semester course. With a more powerful solar cell our experiment fly.

15. Final Comments Frankie – This project was good but we haven’t all the tools on department to make it. Gabriel – The project put our creativity to other levels. Felix – I think the project was good and I work very hard because I need it to pass the class.
