Device to survive during avalanche

    I'm not really sure if it is possible to make my idea come true but here it is...

    I want to provide skiers and snowboarders with avalanche survival devices to put to their backpacks.
    In case of an avalanche a sensor built-in the device will trigger the system and a mask will pop out to fit a face. As soon as the avalanche hits a person, a small vacuum pump will suck snow into the canister, melt it, and split the water made from the melted snow into oxygen and hydrogen. The oxygen will flow through face mask to keep a person alive until someone finds him.
