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.
Thanks Bill! How about a version of this as a personal liferaft?
