Claim 16:
17. A propeller, comprising:
a rotatable hub configured to attach to or be integral with a power axle that operatively provides rotational force to said rotatable hub;
a ring structure including an inner ring spaced apart from said rotatable hub, shovel blades fixed to said inner ring and situated equiangularly around said rotatable hub, and an annular, outer ring spaced apart and outward from said inner ring, said outer ring being tapered at an angle radially outward from an axial rear edge of said outer ring to an axial front edge of said outer ring in a direction toward the axial front edge of said outer ring such that the axial front edge of said outer ring is radially outward of the axial rear edge of said outer ring,
each of said shovel blades being connected at an inner lateral edge to an outer surface of said inner ring, being connected at an outer lateral edge to an inner surface of said outer 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
rigid, elongate connector rods each connected at a first longitudinal end to an inner surface of said inner ring and at a second longitudinal end opposite the first longitudinal end to said rotatable hub, said connector rods being spaced equiangularly around said rotatable hub and arranged to connect to said inner ring opposite a location at which a respective portion of said shovel blades is situated.
