Primal Air Farming - Easy Gold For Engineers

I don't know how many people noticed that I transferred my Mage to horde side about a week or two ago, since then I've been trying to find ways to make money with engineering. I've found that farming Primal Air in Nagrand by using the Zapthrottle Mote Extractor is an excellent way to make gold! The place to farm them is in Nagrand, there are roughly 10-12 "clouds" that can be farmed.

What is this Zapthrottle Mote Extractor? Where do I get it?
The Mote extractor is a engineering device that "extracts" motes from Mini clouds that are all over Outlands and Northrend. To obtain the schematic, you have to go pick up a quest in Zangarmarsh. The quest can be started at Mack Diver, for the horde, and K. Lee Smallfry. The quest is fairly easy to do, it can be done in under 5 or even 10 minutes.

I have the schematic where do I go??
You are going to be flying around Nagrand. There are 10-12 clouds around that can be farmed continuously, especially since not many people know about the mote extractor. Click this map to view where the motes "spawn"

So why does primal air STILL sell? This stuff is from BC!

The main reason this stuff still sells is because people are doing the transmutation master quest, to either keep it and then drop it and changing it to elixir or potion spec, but either way, they need 5 of almost every primal that is available in Burning Crusade.

Another great reason this stuff still sells is because of the twink enchant, 15 agility to gloves. I must admit, not many people have this enchant but the few that do have it, are most definitely buying primal airs, rather than going out and farming them.
