A back pack that charge electricity while you are hiking
This product is great for Soldiers, Hikers and Search & Rescue teams, not because it can charge electricity while using it but it also reduce stress on the body. It eliminates the accelerative forces that cause injuries and reduce mobility. They use a patented pulley system, the pack reduces the metabolic energy requirement by 40-80 watts, allowing a wearer to carry 8-12 extra pounds “for free.”
