We all know that oil is good, better than air, but that air keeps the transformer cool, requiring no external device. We can blow air through as fast as we like, with a very small amount of energy, and there is nothing like a good draft of air to keep things cool.

Mr. Ensign: Regarding the matter of efficiency, so far as I can understand the transformer design, you can make the efficiency what you please if you put the proper bulk in it. If you have to allow air space, you make your transformer that much heavier, and get the same efficiency that you have when you have lowered the insulating space.
