An Israeli company specialising in water treatment and desalination has come up with a process to make snow using the 'vacuum evaporation' of water.
The equipment, produced by IDE Technologies, is based on their Vacuum Ice Machine. The new process, which they call the All Weather Snowmaker, is designed to make snow at "all ambient temperatures" (i.e. all air temperatures).
This report from Ropeways.net.

On the surface this looks very interesting, though the process may not be quite as energy efficient as the manufacturers claim. Existing methods for making snow at 'over-zero' air temperatures include super-freezing an air-water mix with liquid nitrogen - so-called 'cryogenic' snowmaking - to achieve this. I have a video of snow being made at Ayers Rock in Australia in the 1980s, in scorching air temperatures, using cryogenics.
Any comments?

Well I could say, "cool" 
However the power requirements look pretty high and the structures required are much larger than conventional snow cannon, the smallest unit is some 2.7M in diameter and 6M high which produces 170 cubic meters of snow per day but needing 1139Kwh or using about 47.5 Kw per hour which is a lot of power

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

How does that compare with conventional snow making ?

We are having an outdoor ice rink in Chester this Christmas / January, it sounds great but can’t help but think it’s going to be a bit slushy!

Anyway, snowHeads is much more fun if you do.

Probably best to take your slushboard, then

When they tell us how it really works, maybe we can comment!

This is how it works:
That's the IDE Vacuum Ice / Snow Machine. More details here.
