6 FAQs about [Aluminum-hydrogen peroxide power system for an unmanned underwater vehicle]
How a vehicle can be driven underwater?
A vehicle can be driven underwater using power systems and environmental energy conversion by applying ocean thermal energy to change the vehicle's buoyancy and commutating the electrical power generated from a mini WECS (Wave Energy Conversion System) installed inside the vehicle. Solar panels can also be installed on the surface of the vehicle to contribute to the power generation.
Can hybrid power systems be used in underwater vehicles?
Hybrid power systems can be used in unmanned underwater vehicles*. According to Griffiths, hybrid fuel/cell battery energy systems for AUVs (Autonomous Underwater Vehicles) can be modeled realistically using a virtual test bed (VTB) for power systems. Q.

Which power supply is best for unmanned underwater vehicles?
Environmental energy conversion is the most promising choice of power supply for unmanned underwater vehicles (ROVs), as represented in Section 5. It is giant, clean, and regenerative, and has a brighter future and more applications.
How can environmental energy be used to power underwater vehicles?
Environmental energy can be used to power underwater vehicles in a huge, clean, and renewable way, helping the vehicle complete long duration missions, even unmanned station keeping missions. Solar energy, ocean thermal energy, and wave energy are some forms of environmental energy and their conversions are discussed in Section 4.
What are autonomous underwater vehicles?
Autonomous underwater vehicles (AUVs) are programmable, robotic vehicles that, depending on their design, can drift, drive, or glide through the ocean without real-time control by human operators . In this paper we will limit our discussion to AUVs that can follow a planned trajectory with a chosen depth profile, thus excluding gliders.
What are the different types of unmanned underwater vehicles?
The present unmanned underwater vehicles can mainly be classified into three types: remote operated underwater vehicles (ROVs), autonomous underwater vehicles (AUVs), and autonomous underwater gliders (AUGs). They are applied to complete different missions under different working conditions.
