what about using it as a high power HV DC supply driving a conventional
sparkgap coil?  Some sort of charging reactor and you're all set.

Basically, it should be a 1kW, 4-5 kV supply.  A bit of reengineering might
be able to reverse the output polarity, so you could run two back to back
for a 10kV 2kW supply, which would nicely load down a 110V outlet..

Hmmm.. might be time to go spend $60 at Costco (where they have these, last
time I was in there... you can tell because the box doesn't weigh very much)
