Abstract: An energy generation device for mobile carriers is disclosed. The mobile carrier moves in a fluid environment. The disclosed device contains a rotating mechanical unit, a power generation unit, and a power storage unit. The rotating mechanical unit is connected to the surface of the mobile carrier, and is exposed in the fluid environment for converting the fluid kinetic energy into rotational energy. In addition, the power generation unit converts the rotational energy into electrical energy, which is then stored in the power storage unit.

Abstract: A traffic system is disclosed to include a passageway defining a moving direction and a vehicle mounted in the passageway and running along the moving direction. In one instance, the passageway has two inner side walls and an inner bottom wall having a transverse cross-section formed into a continuous smooth surface. In further a instance, there is provided with a buoyant fluid stored in the passageway for generating a buoyancy while displaced by the vehicle. A traffic method is also provided to include steps of providing a vehicle, providing a medium for carrying thereon the vehicle moving therealong, and providing a buoyant medium for reducing a weight of the vehicle.
