I am not considering submerging anything. I am considering using a mixture of Ethanol and Mineral oil as my coolant. The reason for this is simple.
1. Ethanol simply can't be beat for it's low temperature resistance to freezing (-117*C).
2. Mineral oil is commonly used in electrical systems because of it's insulating qualities.
3. Mineral oil is a natural lubricant, and would serve to protect the pump.

I am still looking at other solutions as well, and will keep all updated. Transformer fluid is also coming up.
