RE: Spheres vs Toriods

Any comments on the Wardenclyffe Transmitter electrode? It seems to be
something between spherical to toroidal to almost egg shaped. There also is
what appears to be horizontal rows of points defining the cone shaped upper
portion. Wires also appear to interconnect the electrode points defining the
surface in general. Could this be some of the refinements over the actual
Magnifier patent (1,119,732) that Tesla talks about (Nikola Tesla on His
Work With Alternating Currents by Leland Anderson, pp. 145 - 146)?
