First Claim
1. A kinetic energy conversion hydrofoil, comprising:
- a) an elongated body having a predetermined height and comprising a first side and a first opposing side, a second side and a second opposing side, a tapered leading edge and a trailing edge of a plurality of flight components, said first and said first opposing sides being planarly asymmetrical and said second side and said second opposing sides being planarly symmetrical;
b) a bow stem disposed at said tapered leading edges;
c) a plurality of rails disposed along the length of said first side;
d) said first side comprising a turbine having a protruding shaft at a proximal end thereof and comprising bracketed bearings and a nacelle shield attached thereto and a protruding shaft at a distal end thereof comprising bracketed bearings, drive shaft linkages and a shield attached thereto, a semi-cylindrical shroud having sides disposed laterally at said plurality of rails, said semi-cylindrical shroud having a proximal end comprising a linear expansion nozzle disposed at said bow stem and a distal end comprising an annular cambered wing comprising a variable leading edge disposed at the distal end of said semi cylindrical shroud having a linear dimension greater than the linear dimension of an arc of said semi-cylindrical shroud at an angle within a range of 90 degrees to 135 degrees to an elongated flat laminar-flow plane, a variable width and a variable trailing edge disposed at the extremity of said elongated body; and
e) said first opposing side of said elongated body comprising the elongated flat laminar-flow plane.

Abstract
Disclosed herein is a crosscurrent tacking portable hydrokinetic energy conversion hydrofoil useful for generating electricity in moderate velocity currents and especially useful for rapid deployment and removal from a land base, boat or dock. The device comprises a buoyant and ballasted semi-cylindrical shroud containing a turbine rotor, annular cylindrical wing, a linear expansion nozzle, an alternator with linkages to a turbine shaft, an insulated conductor cable and tether lines. Hydrofoil elements enable the device to tack into a stream and hold a stable position. A system using two tether lines, each with one end connected to the device are fed into a stream to a desired distance from a surface base and are subsequently individually tensioned and fixed to a point on the base, stabilizing the device.
