A direct high voltage flow-through water heater system transmits high voltage power to a remote ice penetrating robot, converts the power to heat in a very small space, and then uses the heat to melt the ice, providing a path ahead of the robot allowing penetration deeper into a remote ice-covered location, such ice of substantial (e.g., kilometers) thickness, such as, for example, glacial ice caps. High voltage, low current, AC power is passed through a moving conducting fluid, inducing resistive heating in the fluid with 100% efficiency. The exiting fluid is stripped of common mode voltage before exiting. Energy transfer from the electrical source to the fluid is instantaneous and occurs at 100% efficiency. In an alternative embodiment, the fluid heater system operates at standard residential/industrial mains voltages and runs from 220 VAC as other applications of the present invention include the traditional water heater industry as well.

An ice auger handle attachment assembly that includes a first bushing with a recess on the end side for a first pin of a handle, a second bushing with two symmetrical flat side surfaces made on the part of the length of the second bushing and having arcuate recesses that form stops. The second bushing partially covers the first bushing and is attached thereto by means of a stud fixed on the end of the handle. Further, a blocking element and the second pin pass through a slot in the second bushing and a hole in the stud. A spring is mounted on the stud between the first and second bushings, and a fork-shaped lever covering the second bushing in the area of the flat side surfaces and hinged thereon by means of the second pin.

The invention relates to a melting head (1) for an ice melting apparatus (1, 8) comprising a rear, in relation to the propagation direction, attachment region (4) for attaching to a drilling apparatus (8) or a drilling rod assembly, and a forward, in relation to the propagation direction, heatable front region (1c), wherein the front region (1c) has a radially outer face region (1a) in which the front region (1c) has an outer cross section that tapers in the propagation direction (3) up to the forward axial melting head end (1d), in particular with a tapering outer diameter, and the radially outer face region (1a) surrounds an inner cavity (5), the free inner cross section of which reduces from the axial melting head end (1d) counter to the propagation direction (3). The invention also relates to an ice melting apparatus (1, 8) formed with the melting head (1).

The present invention relates to a receiver hitch-mounted ice drill device for ice fishing. The device allows a user to move an ice drill while attached to a vehicle while the drill remains outside of the vehicle. In addition, the device allows a user to remotely operate an ice drill of the device from within a vehicle.
