Claim 9:
10. A propeller, comprising:
a rotatable hub;
a ring structure including an inner ring spaced apart from said rotatable hub, shovel blades fixed to said inner ring and separated blade guides on an opposite side of said shovel blades from said inner ring,
each of said shovel blades being connected at an inner lateral edge to an outer surface of said inner ring and being angled rearward,
said shovel blades being spaced apart from one another in a circumferential direction such that a leading edge of each of said shovel blades does not overlie a trailing edge of an immediately adjacent one of said shovel blades and the trailing edge of each of said shovel blades does not underlie the leading edge of an immediately adjacent one of said shovel blades; and

connection means for connecting said inner ring to said rotatable hub through a space between said inner ring and said rotatable hub, and
wherein said blade guides are configured such that a portion including a front edge of each of said blade guides overlies a rear edge of an adjoining one of said blade guides to form gaps in a radial direction of said ring structure between adjacent ones of said blade guides leading into an interior space defined by said ring structure,
whereby upon rotation of the propeller, fluid flows into the interior space defined by said ring structure through the gaps and interacts with said shovel blades.
