The real question this raises to my mind is why would you want to run a
tesla coil without a secondary?
Loneoceans mentions running a tesla coil without a secondary (but with a big
piece of iron or metal pot filled with water instead) as part of the set-up
for the phase lead adjustment on an advanced driver board for a DRSSTC. But
that is a very specialised circumstance (and is not an end in itself).
