Tesla actually had a number of similar ideas and noted them as early as 1893 but
his book compiled by T.C. Martin in 1894 offer up a number of such schemes.  Also
wardenclyffe was to be 3 phase excited along these lines in some original copies of
his correspondence.

For amateur use it is just plan overkill, but good luck.
