Abstract: 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.

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.
