Is this a giant Slush Puppy.?
EDIT:- The tech details are encouraging. Seems it can tolerate hill-water, and the mid-sized unit can produce 960m^3 per day, with a water supply of 5-6 l/sec. Power consumtion 6.7 kwh per m^3, if water supply is +5C, which I expect Scottish Hill-Water would not exceed in winter.
It sounds like a "spring-snow" maker judging by how the granular snow is separated from the water. I don't think this snow would be liable to blow away after it was put down.
