The Ryazan Higher Airborne Command School (RHACS) has developed an Arctic survival kit fed by portable battery, RHACS Research Section chief Col. Vasily Yelistratov reports.  

"A portable accumulator, like a 5,000 mAh reserve battery for a cell phone, is enough to power the heater for three and a half hours," he told the Army-2018 Forum.

The kit is specific in that it heats only the vital parts of the body, something that makes it highly energy efficient.

"There is no need to heat the whole body. We have determined the spots where heating is advisable to maximize energy efficiency — the backbone area, the limbs," he noted.

If a portable accumulator is lacking, the system can be powered by car, snowmobile or ATV batteries. This is why the inventors believe the survival kit could be used by both the military and civilians.
