I'm going to build them all as soon as I get the metal cut, and all the end caps and everything needed for the pvc. It's going to be a fairly tedious job to do all of this, but I'm going to get it done asap. I went to a metal scrapper that sells used metal. This piece happened to be there, and the absolute perfect size for my needs. It's not even a used piece, it's an end cut, and it's about 8 sq. feet. $38. Pretty good price!! I like end cuts

Anyway, I believe I should get some good efficiency out of this.
Bob, a couple questions:
It should be okay with the .25 amps/sq inch to run the 7 units until they warm up, and then add the 8th unit, and it should actually run efficiently, no? Or will it not have enough power (voltage) going through?
Also, for future testing, I believe you said that resonance should work in these submerged cell types as well, but it would require a different driver for each individual unit, is this right?.
And, if you had to choose, I guess you would suggest trying resonance with your series cells as opposed to these types??
Thanks!
