A Self-Contained Experimental Diver Heater
Abstract
Free-swimming divers working in cold water for extended periods of time require a self-contained, active heat source to maintain their physiological thermal equilibrium. Previously, the accelerated reaction of magnesium with seawater was shown to be a suitable heat source of diving applications. The magnesium heat cell was configured as a short-circuited battery with alternate electrodes of magnesium and steel spaced closely together; the unit is activated by immersion in a seawater electrolyte. An experimental heater was fabricated that incorporated known improvements in the cell. The self-contained unit provided 1,000 watts for up to 8 hours. A human factors study was made that identifies heater configurations for closed-circuit scuba divers.
