I'm researching the ionocraft, commonly called a "lifter":

These require tens of thousands of volts. Usually heavy iron cored transformers are used to create the high voltages. But this means the power supply is heavy and the ionocraft can't lift them.
But how lightweight can an air cored transformer be? Less than 1 gram weight per watt power output would be ideal.
