It was nice of you to provide subtitles for the alien audience!

Toxo Was just gonna say that 😂

"Wet bulb temperature" is nicely explained to figure temperature and humidity variations for more efficient snow making. Thank you.
Really wonderful production Joel! Having followed OnTheSnow's progression over the past few years I can tell you I am more than excited to see what the future holds for you. Between your spot-on predictions and your continually exemplified passion for what you do, I sincerely wish you all the best. Bring on the pow!

Cool video. Check your facts. You have most of it. It comes down to two different styles of guns. Internal nucleation and external nucleation. The closet thing to an air less gun is snow logic, and hkd vipers. They operate on as little as 5 psi. The SMI pole cat fan gun in your video that you refer to as air less is in fact very different. They operate with a water source that is mountain provided and have a on board compressor that generates the air necessary for the nucleation process. Snow making companies around the globe strive to reach as low of a PSI that can pump through the machines to create snow as air is the most expensive component. No air less guns on the market as of now being march of 2016. Thank you and god bless snow makers world wide. More then happy to go further in depth.
+bosh boy Well said, actually, there is one producer on the market called Nivis, they use a special nozzle with a tiny chimney, using the venturi effect to mix the water with surrounding air. This seems working, however the snow production is aroud half the volume of a standard on-board compressor equipped snowgun.
At cardrona, new zealand, we make snow at up to +3 degrees C. humidity is usually pretty low so that helps
The "airless" snow gun, is not airless at all, there's a compressor under the main cone. Fan blows out the the water, already mixed with water. There are different sets of nozzles, of which some are called "nucleators", which mix air and water and create so-called nucleation core, which creates a solid base for a snowflake formation. In fact, there've never been working "airless" snowguns, because it's impossible. There were some models using venturi effect, but again, it needed certain amount of air to be pulled into water nozzle in order to make it freeze. During the air expansion, the air temperature falls down to -30 or less (depending on the air pressure), that's why the compressed air is mandatory in snowmaking.
Thank you for correctly stating how a fan gun works. But the smi 320s were airless guns. Very neat concept of water freezing on the fan blades & shearing off.

I study ski area operations in Leadville Colorado, and interestingly enough we have a truly airless and powerless gun. its called the York water stick. it is old and inefficient and the snow quality sucks and requires a temp of 14 degrees or lower. I also make snow for Keystone Resort and in speaking with my controller i have learned that our HKD tower guns will also make snow with only water (no air) in 9 degree or lower temps. all temps are wet bulb measurements.
great !!
Closed Captioning is really messed up in this video lol.
first video to mention wet bulb, good one
Sick ass video you remind me of the dude that got locked up in ‘The Office’ XD
What are these subtitles?
Both require 2 inputs......Power & Water and Air & Water
There's going to be alot of people here when youtube randomly recommends this in the future.
I on the other hand, had no idea people could Ski in Las Vegas
@ftwcm - You have an eagle eye! Yes, the fan gun that we used in the video does use compressed air, though we wanted to use that gun because it looks similar to an airless gun and we didn't have easy access to a true airless gun.
About the expansion of the compressed air, that works in tandem with evaporational cooling to chill the air, but I didn't want to lump too many concepts into one video.
Thanks for your comment!
JOEL
yea, i think if anyone is watching this video they already have some knowledge of snow guns and want to broaden what they know on the subject.
I have a question, I’m really into using water a lot and I want to make snow at resorts near me. Do you know how can I become a snow maker?
fan guns have compressors and nucleation nozzles as well... do some freaking research
You can even see the nucleator when they turn the fan gun on...
yEAHHH! New Zealand Represent !
What chemicals do you put in the water now?
I wanna quit my job and get a job at a ski resort .
No. No you don’t
I did just this and it’s fucking awesome. Do it man
nice vid dude👍🙂
Is their any way to make snow with temperatures above 32 degrees to 120 degrees?
I want to make snow in my country - Vietnam, I have a ideal about an entertainment zone with snow for my people who mostly can not afford to have trip to the cold area to see snow.
+Benjamin Castillo Says who? These in the video won't, but there are several alternative solutions, that can be provided. ;)
I wished you provided the temperature in Celsius, at least in brackets. Or you bothered to mention that the temperature references in the video are in Fahrenheit. You got me confused, bro.
timberline at mount hood refuses to do snowmaking
SUPER
Do you like one or two inputs guys?
It's not fake snow, it's frozen water just like the snow that falls from the sky
dont you need condensation nuclei too? ive tried making snow before at home with compressed air and water but it didn't work, we think because we didnt have condensation nuclei
just needs to be cold
If you use a wide fan spray power washer nozzle on the end of your air water gun & wet bulb is 24 or colder with a water & air psi of at least 60psi you can make snow. Best is air at 80psi & water 0ver 100psi. Using a power washer & air compressor will allow you to go as crazy as you want.
Can you make snow in California
i was succes making natural rain using salt,,in a java island size,,anybody could share making natural snow in a continental size,,million thanks,,best regard,,hhe
not true... both guns require compressed air and water. the fan gun has an on-board compressor- the center nozzle is air + water and the rings of nozzles are just water, the fan is just for throw/ hang time
is there a way to make snow in the desert?
One might want a water source, first. This could be hard to find in a desert...
+nicholas templer Yes. There is a way. For example, Snow Factory of Technoalpin. :) It's a giant freezer which can produce snow wherever you want, no matter what climate.
It can snow naturally in the american deserts due to its high elevation and low humidity, so yes its possible.
Surprised how automated some of these systems are now. Cool stuff, though of course real snow is always the best. ;-)
+association330 real snow is the same as snow they make.... unless you live in a warm climate some snowmaking systems push "snowmax" into the water to help the snow form before it lands.
+ore knot It's called "SNOMAX" formerly developed by York and these bacteria-based additives are not intended to push the freezing level higher, but to increase the quality of snow where the climate conditions are wet therefore producing sticky snow and to form a proper nucleation core where the water is too pure, having problems to freeze.
i thought california was hot
how do you make snow if its hot
my dog California has mountains and mountains = cold
Wait what’s wrong with the subtitles 😂

electricity is an input
Why making snow🙄
it fen.
which is bettter
Why does fresh snow from these guns stick like glue and make everyone fall over when they hit it?

This is SOOOOO complicated
Who else is here doing research on the fake snow, cause of what snow fall in Texas?😭😂
The guns seem kind of like fuel injectors.
Yo what the fucking shit is wrong with the subtitles
