I'm not sure if surface area is as much a factor as mass. More mass = more atoms that can take on more electrons and give electrons. I'd say it's a combination of both, but mass seems more immediately relevant. I've run my maggie (1.6kW) at my school a few times now. The first couple of times, I used an old (and rather large) arbor press. The last time (at a talent show), I threw a 3in*3in*~5ft steel bar that was laying around in the metal storeroom on a metal cart. If you spread a bunch of chicken wire out, you're liable to have an arc pass from it to a conductor under the floor or somewhere else. I once used a large steel cart as a ground; it sat on cement and where the wheels touched, large amounts of corona were visible. Be careful with isolated grounds, I accidentally touched the cart during the talent show; no one could tell but it didn't feel very good. BTW, how long of arcs are you getting with 225VA?

I have to operate a tesla coil in a gym for a demonstration, how much chicken wire should i use for a proper ground?
Coil is powered by 9000v 25ma NST, secondary is 3.5" by 18" and topload is about 37.5" off the ground.
