I think there has been a posit about this product, but HERE is a good write-up on the new technology from BlackDiamond and PIEPS:
Battery operated airbag- no cylinder, easy air travel, don;t have to hunt for a place to recharge the cylinder, can even practice deployment at home.
Battery operated fan gives an infinite supply or air, can run a larger airbag and be somewhat resistant to minor tears and punctures
Fan automatically deflates the bag after several minutes, giving a buried victim a potentially large air pocket
Does not inflate as fast as the cylinder-powered airbags.
Li-ion batteries are vulnerable to the cold and to aging.
Time will tell, but it seems to be a real evolution in the airbag technology.
