Avalanche Survival Tool
This is an idea that I have thought of. It works like this. The Avalanche Survival Tool is enclosed in a backpack. If you are out skiing or snowboarding and you are caught in an avalanche, the built-in sensor will detect it and trigger the system. A mask will pop out to fit your face, and as soon as the avalanche has hit you, a small vacuum pump in the tool sucks snow into the canister, melts the snow, and splits the water made from the melted snow into oxygen and hydrogen. The oxygen flows through your face mask to keep you alive until someone finds you.
