An apparatus for winding a thread around a surface of an object while rotating the object. Said sawn grooves allow for tensional force to open the nutshell in three pieces resulting in the exposure of large nutmeat pieces for easy pick-out removal. At the south pole of the enclosure, water is expelled into a high-pressure injection well descending to a geological level of a saline aquifer or discharged from a water chamber at the south pole and into a main water body under pressure provided to a discharge chamber in excess of the ambient deep-water pressure. The dipole is effectively end fed rather then center fed, and pattern distortion and axial asymmetry are minimized.
