New to me...

Here is a video of it being used at Baldface in the Nelson, BC area.

new to me.  pretty cool.

The Daisy Bell hangs 150 feet from a helicopter and moves snow by emitting precise blasts using mixtures of oxygen and hydrogen. The idea is this device, which looks like a space capsule, will replace the need for moving snow with explosives

The Daisy Bell costs $130,000 and weighs around 1,100 pounds, including gas bottles.

The compressed gas is much cheaper than explosives, but that doesn't really account for the heli time.
