9. Electrical Diagram

10. CurrentVoltagePower Source: Solar Panels.8012V (6V each) 9.6W Motor 1.98 max 12V (max) 23.76W max

11. Electrical Safety Considerations We made sure that the motor was capable to resist the max voltage the solar panels could provide which are 12 volts. The motor has a voltage range from 9 to 18V. We made sure that the motor was capable to resist the max voltage the solar panels could provide which are 12 volts. The motor has a voltage range from 9 to 18V. For the propeller to turn in the right direction we made sure the polarity was correctly installed. For the propeller to turn in the right direction we made sure the polarity was correctly installed. Every wire is covered and all joints were made with electrical tape to prevent electrical safety hazards.

13. Mechanical Safety Considerations We made sure that all implements could withstand the stress the motor would create We made sure that all implements could withstand the stress the motor would create We used water resistant adhesives to ensure the sturdiness of the boat. We used water resistant adhesives to ensure the sturdiness of the boat. All the parts were the adequate size to ensure the proportionality and the distribution of the weight. All the parts were the adequate size to ensure the proportionality and the distribution of the weight.

14. Mechanical Safety Considerations This is to prevent the boat from sinking the nose This is to prevent the boat from sinking the nose The motor is isolated from the water The motor is isolated from the water

15. Passenger Transport Area Set up was simple. We used a cushioned seat small enough to hold the egg. It has bumps that keeps the egg in place Set up was simple. We used a cushioned seat small enough to hold the egg. It has bumps that keeps the egg in place

16. Main Challenges Find an appropriate Source for the power requirements of the motor Find an appropriate Source for the power requirements of the motor Make Sure that the floating device could hold the boat afloat. Make Sure that the floating device could hold the boat afloat. Also the adhesive components were not working as desired but we found several ways to solve the problem Also the adhesive components were not working as desired but we found several ways to solve the problem
