Système de récuperation de dechets
Masse cible (m) = 900g soit 0,9kg
Masse volumique Déchets en plastique ≈ 50kg/m³
Volume = m/Mv soit V= 0,9 / 50 = 0,018 m³
0,018 * 1000 = 18 Litres
Largeur l : 30cm Longueur L : 30cm Profondeur : 20cm
Profondeur = V/ L*l soit 18000cm / 30*30 = 20cm

Conclusion
1. Introduction & Project Goal (0:00 - 1:00) "Hello everyone. My name is Etienne Baumier. Today, I am happy to present my final project: 'Project Boat'. Our planet faces a big problem: plastic pollution in the oceans. Most of this plastic comes from rivers and ports. Our goal was to design an eco-friendly remote-controlled boat. This boat can collect waste directly on the water's surface in enclosed basins, like ports. I worked in a team with Jules, who designed the hull, and Lucas, who worked on the collection system. My specific mission was the motorization and the energy management." 2. Technical Field: Calculations & Steering (1:00 - 2:30) "To make a good boat, I had to do many calculations. First, the speed. The project requirements say the boat must reach 4 km/h. I calculated that we need a thrust of 2.38 Newtons to fight the water resistance. For the direction, we chose a 'differential steering' system. It is very interesting because there is no mechanical rudder. We have two motors. To turn right, the left motor spins faster than the right motor. This makes the boat very maneuverable in small spaces." 3. Energy Choice & Results (2:30 - 3:45) "Next, I worked on the energy flow. I did hydrostatic calculations to find the submerged surface of the hull. This is important to know the weight we can carry. The boat can carry 900g of trash. I selected a Li-Po 2S battery with 7000 mAh. Why? Because the boat must work for 4 hours without stopping. I also chose two Brushless motors. They are more expensive than normal motors, but the efficiency is much higher. This means we waste less energy as heat." 4. Challenges & Solutions (3:45 - 4:30) "We faced several challenges. The biggest one was the 'power vs range' paradox: how to be powerful but stay autonomous for 4 hours? My solution was to optimize the energy flow and use ducted propellers to increase thrust. We also worked on the sealing. The electronics are protected with an IP44 index. This means the boat is safe from water splashes." 5. Conclusion: Impact & Personal Opening (4:30 - 5:00) "To conclude, this project was a great experience. We successfully built a boat that is 'Carbon Negative'. This means the CO2 saved by collecting plastic is 700 times higher than the CO2 produced by the battery! Technically, all the objectives are reached: the speed, the 4-hour autonomy, and the 900g capacity. On a personal level, I learned how to manage a complex energy chain and how to work in a professional engineering team. The next step could be to add a solar panel on the deck to make the boat 100% autonomous with renewable energy. Thank you for your attention. I am now ready for your questions."
