OK. I understand, now. Might be a very workable solution. We'd
probably want to experiment with different things. Certainly, a
plastic-like material would be easier to produce in large sheets, but you'd
need to get something that could conduct the electricty, and I think the
two-sided approach for flow-through of water might still work better.

Yes. Lots and lots of little pieces that all fit together. They may
all be the same size, but there are a lot of 'em.

OK. But conductivity is the main issue. And you can put more
current through metal wire/rebar than through a metalic powder on a plastic
surface.
