Environmental Consideration:
Squaw Valley made huge headway in a multi-year effort to replace the resort’s 250 old snowmaking guns (40s) with new more efficient B3s and extremely efficient SMI fan guns. An old 40 uses as much energy as approximately 2 B3s or 15 SMI fan guns. As of this season, Squaw Valley has replaced 190 of the old 40s with 90 B3s and 4 fan guns. Therefore, approximately 92% of the old snowmaking machines have been replaced. The old snowmaking guns were either re-sold or recycled (aluminum). Squaw Valley snowmaking utilizes a natural snowmaking process that uses 100% recaptured water (snowmelt) rather than extracting from the domestic water supply. This results in significant non-consumptive water conservation each season.
Can any industry guys explain the 40s and B3s? The 40s sound like the old Larchmonts that look like machine guns.

I am not sure about about the 40 gun. However a b3, better known as a borax made by Johnson controls snow (formerly york) is a air water gun that uses much less air than your standard air water gun, but it still has pretty good capacity and throw. here is a link
