1. Apparatus for generating energy from a source of fluid in motion comprising:
- means disposed in the fluid for torsional movement in response to the movement of the fluid therepast, said means including a flexible member;
means operably coupled to said torsional movement means for converting said torsional movement into usable energy; and
said converting means including;
a first arm;
means for securing said flexible member to said first arm at one point on the flexible member;
a second flexible arm;
means for securing said flexible member to said second flexible arm at another point on the flexible member spaced from the one point, said second flexible arm being displaceable by the torsional movement of the flexible member;
a transducer; and
second means for operably coupling said transducer to said second flexible arm.
