Abstract: An airborne ElectroMagnetic (EM) survey system wherein the system includes; first, a series of transmitter coils, which induce a primary (EM) field into the earth resulting in a secondary EM field being created in any sub-surface electrically conductive bodies; and second, a set of three orthogonal receiver coils which detect the secondary EM field. Multiple transmitter coils through which an electric current is pumped, form part of the structural, aluminum framework of a multi-rotor drone. The receiver sensor may be an EM induction sensor, comprised of multi-turn, copper windings, mounted inside an aerodynamic bird and separated by non-conductive sphalerite, which acts as an electrical insulator to limit self-induction and capacitance. Additionally a lighter-than-air balloon may be used to add vertical lift and increase a pendulum effect.

Abstract: A wave energy device converts the motion of waves on a body of water into a usable form of energy, for example a flow of pressurized water or an electrical current. The device includes a buoyant body for tracking the rise and fall of the waves and a working surface coupled for movement with the buoyant body and which is designed to capture and convert both heave and surge forces of the waves. The invention also involves a rapid deployment and retrieval capability and a capability to rotate to accommodate changes in wave direction. The device is universally attached to the seafloor, which allows the device to safely pitch, yaw and roll with the wave forces from any direction thereby reducing the likelihood of damage due to extreme weather or marine traffic. The universal attachment also allows the device to automatically adjust for varying water elevation due to tides.

Abstract: An apparatus and method for converting the motion of waves on a body of fluid into useable energy. The apparatus includes a floating or fixed rotatable support structure, a lever arm(s) pivotally supported from the support structure, and a wave follower fixed to one end of the lever arm(s) and positioned on the body of fluid. The lever arm is connected to an energy transfer device such as a piston rod which drives a load in response to the action of waves on the wave follower. The wave follower is designed such that the upper portion is constructed of a buoyant substance and the lower portion constructed in the form of a hollow chamber, open at the bottom, with the seaward face being angled so as to harness the energy of the lateral force of the wave. The open bottom of the wave follower allows the chamber to fill with fluid generally on the rise of a wave. When the fluid level drops, a suction is created in the chamber by the closing of a valve located in the upper portion.
