I have here the highest isolation DC/DC converter IC I could find: the
6kVDC isolation DC/DC converter NMS0515 (5Vin, 15Vout, 67mA output),
and it's giving me a headache. I need 15Vdc and about 100mA with 30kV
isolation from the input.

How about a solar cell and a headlight bulb? Crap efficiency, but
isolation off the charts - you've got a few inches of vacuum (and/or gas
fill) and at least an eighth of an inch of glass working for you, and
then you can put the solar cell further away for more isolation (at a
reduced power output).

You can do better with a motor-generator set with a long plastic shaft.
The head light's light decreases as the square of distance but the losses
in a shaft are only linear with distance.
