I have thought about keeping the primary coil in mineral oil for heat

use to keep your LF antennas cool?
Why not using a copper pipe and circulating distilled water (or car antifreeze
fluid) inside it? The fluid MUST be non-conductive! I have seen a kW power
amplifier project for 23 cm in an ARLL Handbook using this cooling system.
