Note also that the balls attached to the ends act as doorknob capacitors, resulting in tuned tank circuits on both ends of the transmission line. Energy is temporarily stored in these tank circuits before being shuttled off back down the line during the next part of the cycle. Tesla also spoke of keeping the leakage of the capacitors to a minimum.

[snip] I think the reason that no one else has succeeded is because they didn't approach it on a grand enough scale. It takes a lot of power to resonate the whole planet. A half-hearted attempt will just result in the signal being absorbed. That's why Tesla's towers were so big. IOW though a fairly good medium, the planet isn't perfect, and until enough power is put in to overcome the losses, any potential resonance will be damped out of existence. Besides, there is another (speculative) aspect to this. When resonating the planet, the magnetic field part of the resonance may interact with the natural magnetic field of the Earth itself, and through that with the Van Allen belts, thereby allowing the energy of the Solar wind to be tapped. Another source of energy potentially coupled to the Earth's magnetic field is the geothermal energy in the Earth's core. The Earth's field might be used to "magnetically cool" the core of the planet, with the energy being dumped into an electrical load as the "cold side". 2LOT isn't violated because the core of the Earth is much hotter than the load (i.e. the surface). Either (both) of the above may explain why he is purported to have gotten more out than he put in. Regards, Robin van Spaandonk The shrub is a plant.
