Means for facilitating the supply of energy, which has a first blade 1 arrangement adapted to spin and provide an inner vortex path, a second blade arrangement 5 adapted to spin and provide an outer vortex path, a fluid which is able to circulate between the vortex paths, and means for extracting energy (eg a shaft 2). The blades of each blade arrangement are configured to cause high pressure and low pressure regions within each vortex path to at least facilitate movement of the fluid through the vortex paths and the means for extracting energy can extract energy from the moving fluid, directly or indirectly. |
