Steve, Wardenclyffe would have been the future, would have been and still will be, in my opinion.
Tesla used a different system within, than his earlier tower work.
This page explains it well and with references and drawings to the revised 1902 Patent: http://www.teslaradio.com/pages/wardenclyffe.htm
What many build as a "Tesla tower' is in fact not how Wardenclyffe ran.
Underneath the tower at Shoreham were tunnels and the system was intended to 'shake the very earth', rather than HAARP the sky to pieces !
We see huge lightning bolt streaks emitting from towers and, yet, that's the inverse of what Tesla wished to see. If Tesla saw a leaping lightning bolt from Wardenclyffe, then the thing needed work !
The energy was supposed to be curtailed at the top (where the dome sat) and returned back down into the Ground - relating to earlier discussions within the emails of this group

As I understand it, the earth itself can be and was considered as a giant capacitive plate conductor. The air above being the other plate (especially the ionosphere). Communications would work, partly, in the 1 wire way...energy being transmitted within the earth.
Extra stuff, but relating to my own fascination, which I hope is in resonance with wishes of the thread.
Energetic Forum was joined, after seeing vids by many who referenced that particular forum. What I was watching, were videos relating to wireless energy. The whole jist of which, was to understand how I might attain another of Tesla's dreams, wireless electric flight.
Of particular note, this thread:
http://www.energeticforum.com/renewable-energy/4999-joulethief-sec-exciter-variants.html wherein, you can find tons of solid state Tesla tower devices that use minimalist energy.
The following includes chat to AllCanadian in the self powered coil thread...but relates here.
In recent months i've not focused on flight, at all really, preferring to spend as much time as my immigration process is allowing, to further all elements of resonance, oscillations, power transference and alternative methods that are related.
But Tesla's energy work is always behind the experiments....wireless flight will be attained.
If we can successfully power little models without onboard power, then we can further that solution, scale it, for real world applications. Let alone that a reduction in weight can be achieved without fuel or batteries.
Here's where experiments were 'at' some months ago. rather embarrassing in some ways, but hopefully an indicator of possibilities:

Of more interest, perhaps, could be this video...an envisaged future of cellphone charging within say a coffee stop at Starbucks and the follow up video, where I demonstrate range.
http://www.youtube.com/watch?v=TAqFLlBm9YAhttp://www.youtube.com/watch?v=XV232BX8FRcThose videos are the only ones where supposed 'science fair' students will regularly send me emails asking how to build such a device ! Work through that one and one may gain the thoughts that in actuality these are cellphone companies. After I outline the method, but not the exact materials, I never do get a follow up or even a thank you from such persons !
For one wire transmission, maybe this video:
