Man made snow above freezing point predictably the environmentalists are not happy.......

Anyone got further info on this? Trying to find out make/model and some technical specifications.
I'm not sure all might not be quite what it seems, in that the report talks about adding extra compressors and pumps to attain higher pressures. Thus possibly all that it is doing is raising the pressures that can be generated within a fan gun to those of traditional air/water systems, which can make snow above freezing in low humidity situations anyway?

Well, the person's real but it's just a made up name, see?

There was some kind of a lorry making snow in L2A village at the PSB and the temp was well above zero

Anyway, snowHeads is much more fun if you do.

It says in the vid that they can make snow when the ambient temp is as high as +5c

You'll need to Register first of course.

boredsurfin,
The machine in L2A was working at between +10 to +15 I reckon. It was housed in a lorry unit

It's possible to make snow in air temperatures above 30C using cryogenic processes (use of liquid gas as a coolant), and those techniques are sometimes used for special effects, film-making etc.
If the ambient air temperature is 5C, and the ground is also warm, the amount of energy required to make super-cooled snow is huge. Once on the ground the snow is subject to the same thawing as any other snow.
