With mastery of electro-gravitics the elevator concept is obsolete.

Perhaps, if electro-gravitics turns out to be more than Art Bell twaddle. But the elevator is built on known physics and materials and is attainable in a timeframe of several decades or at most a century. Electrogravitics-even if real-are a long, long way from being understood or put to practical application.

Don't bet your life savings on that assertion. In the mid seventies, I spent a very interesting evening over beers talking to two professors at the Univ. Of Ala. Huntsville who taught third and fourth level courses on electro-gravitics. Youtube the name Bod Blackmun. By merely putting two neodymium magnets together, he was able to reduce the acceleration of a free-falling object.

And one last hint: Northrup developed gravity reducing 'assists' for conventional stealth aircraft technologies under study way back in the late sixties.
