Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
51 words
Rotor assembly for converting the energy of natural wind into usable mechanical energy, comprising at least two elongated curved blades being rotatable about given axes, said blades being helically twisted about said axes, and each of said blades having portions thereof being inserted between portions of the other of said blades.
Claim 2
Dependent Claim
51 words
