1. A fluid pump comprising:
a compressible rotor comprising:
at least one blade; and
one or more deformable cavities disposed within the at least one blade, the one or more deformable cavities being delimited at least partially by a semipermeable membrane,
wherein the one or more deformable cavities are configured to be filled with a solution, and
wherein the semipermeable membrane is configured to allow osmotic diffusion of a fluid into the one or more deformable cavities when the compressible rotor is submerged in the fluid.
