Abstract: The human powered hydrofoil bicycle includes multiple subsystems integrated together including a structural frame subsystem with associated steering and tiller module, a hydrofoil subsystem to provide vehicle lift, and a powertrain subsystem. The structural frame subsystem may be fitted with buoyancy modules to provide the overall vehicle with a near neutrally buoyant character. The structural frame subsystem also supports a seat for an operator and provides structural support for the steering and tiller module for the hydrofoil subsystem and the drivetrain subsystem. The hydrofoil subsystem includes multiple hydrofoil elements at lowermost portions of the vehicle. These hydrofoil elements generally include in a preferred embodiment a larger rear foil and a smaller front foil. The powertrain subsystem generally includes pedals rotatably supported on the vehicle at a convenient location for engagement and driving by feet of an operator.

Abstract: Disclosed is an apparatus for imparting only shear wave energy into the earth comprising a vibrating pad for connection to a mobile support, such as a wheeled vehicle, and means for vibrating the pad to impart at least two polarizations of shear wave energy into the earth. One such means includes azimuthally rotating the pad and/or the vibration energy generator.
