It would have been a supremely inefficient and ineffective system to send power wirelessly in all directions. Aside from the exponential power losses over the distance, the receivers of the field would have an adverse effect on the transmitter. The more load a receiver puts on the signal, the more the frequency will shift. Wireless receivers are still capacitively coupled to the transmitter through the Earth. A bunch of radio receivers don't alter the transmission frequency of the radio stations because the radio receivers are a miniscule load coupled to the transmitter. Drawing off kilowatts of energy is not the same as drawing off picowatts of energy like a radio receiver would do. As the load varies, the transmitter frequency and modulated waveform will start to change. New harmonics will be induced in the transmitter tuned L/C tank (inductor, capacitor tuned resonator). This will cause less efficiency in the power transmission and the receivers will no longer be tuned properly to receive the signal efficiently or even at all. Add more receivers and more load and the whole thing falls apart. The idea isn't very sound at all. It just doesn't scale well. And even if it did work, radiated signals have many dead zones where the paths of multiple reflected signals can cancel each other out. Imagine your devices failing because they moved from a good zone to a dead zone in the space of just a few feet or less. That doesn't sound very usable. You've probably heard this sort of thing happen with radio stations if you're old enough to have listened to them much in the car. But yeah, let's keep pretending like Tesla was infallible and god-like. He was intelligent, yes, but he made many mistakes and wrong conclusions in his work. Wardenclyffe is one of those bonehead conclusions. Celebrate his real successes like the AC induction motor, fluorescent lighting and the alternating current electrical system instead of these fantastical pipe dreams that ended in failure. He was only a man after all.
