(57) : Energy is harvesting from fluids with different densities, such as water (34) and air (38) with a rotor (12) that is selectively ,t: above and below a water surface (30). The rotor (12) has cavities (31,32) inside tubes (18) with apertures (24) in walls (22) of the tubes ir) (18). In a submerged mode, with the rotor (12) in the water(34), air is trapped in tubes (18) on one side of the rotor (12), which has f.r) apertures (24) facing down and air is released from the tubes (18) on the opposite side of the rotor (12), which has apertures (24) facing ei 1-1 up. The opposite happens in an elevated mode, with the rotor (12) in the air (38) above the water surface (30), in which water escapes N from tubes (18) on one side of the rotor (12), with apertures (24) facing down and water is retained in tubes (18) on the opposite side of IN the rotor (12) with apertures (24) facing up. Mass transfer in the form of the release of water and air from the tubes (18) in the respective ‘ -1 modes, causes imbalances in buoyancy and/or weight of the contents of the tubes (12), which causes the rotor (12) to rotate. 0 ei C [Continued on next page] WO 2017/212356 Al MIDEDIMOMOIDEIRMEMODIHMOIIIMODEVON SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW.
