He He! nice response! I was expecting "Your Nuts! Go away!" but it seems we have some broad minded people here.

Your rad is earthed. So no voltage diff between it and the case etc. And no chance of blowing anything even with a dead short. A dead short should have other interesting effects though!

The Potential Difference lies between the grill and earth/rad.
Favd your link. THX Cathar.
This is out there:
The grill should be - 30 000V to pull heat excited electrons out of the Rad for an extra, obscure, cooling effect... Or is it the other way round??? - Wish I could find that link to a patent...
I wish someone would try this; If the effect has enough juice to
levitate things it should work well. Especially when combined with convection.
