Here is an idea from fellow Inventor Bill Steell.

An Emergency ‘Zorb‘ type ball, for those caught in an avalanche.

Scenario:- Avalanche warning (or see it coming), Deploy your personal Zorb (double layered skin, large ball), emergency inflate using canister and clamber inside.

Avalanche arrives and sweeps ball onwards like a beachball in the tide, due to the rush of air from the force of the avalanche.
