in teslas wireless patent, he describes that his system is superior to the crookes and other designs in creating conducting gasses in the atmosphere. he has proven through experimentation that electricity is efficiently pushed through the air, even at usual non conducting pressures. this allow efficient energy transfer that can be brought down at other points on the earth. he even differentiates his waves from hertzian waves. showing his waves can transfer energy many times better. this research is now considered a form of plasma waves, but they truely were discovered by tesla 100 yrs ago. tesla is even a step above the plasma waves, because he is making some type of “cold” plasma because it can conduct through air without having to make it turn into a discharge of electrical plasma.look up plasma waves, theres tons of different forms.
