Aether is an outdated belief, like flat earth. We believed that electromagnetic energy, which includes light, traveled in waves, and waves require a medium to travel through. However, there is vacuum in space, so we couldn't understand how those waves could travel through space, and theorized that maybe the universe is filled with this aether that energy waves go through. However, there was no way for us to detect that aether, and numerous experiments showed that there is no evidence for its existence, other than that light and radio travel through space somehow. It was much later after Tesla that we discovered that light is both a wave and a particle - photon - and thus that energy can travel through space in particle form. Something like aether, which we could never prove existed, turned out to not be needed for the universe to work, and is thus considered to not be real in science.
In short, not everything Tesla invented was scientifically correct or functional. Especially in his later years when he went from electro mechanical systems, to more theoretical based on ideas that wouldn't be proven false or true for decades later.
Oh, and this sentence on that web site
Their emissions of longitudinal impulses can exceed the speed of light
pretty much confirms my suspicion that it's be. Nothing can exceed the speed of light.
"A Brief History of Superluminal Wave Experiments
1) In 1988 researcher Alexi Guy Obolensky, working together with Prof. Panos Pappas, transmitted electric pulse shock waves at superluminal speed. They published the results of their experiment in Electricity and Wireless World,December 1988, pp. 1162 – 1165.

The above page links are provided on Dr. Pappas’ website. Some of the images are marked with corrections that Dr. Pappas has made to correct mistakes made in the original published manuscript which was mistakenly not sent to A. G. Obolensky for his final review.
2) Also in 1988, Eric Dollard demonstrated an experiment in which he sent longitudinal waves through a coaxial cable at 1.26 c. He discusses this in the following video:

3) In 2005 – 2006 Alexi Guy Obolensky and myself transmitted high voltage Coulomb shock wave pulses across his laboratory at a speed averaging 1.26 c. At 3.07 meters distance the pulse arrived 1.7 nanoseconds faster than luminal speed. Our threshold resolution for distinguishing time delays was 125 picoseconds. The rise time of our shock front was about 0.8 nanoseconds. The speed declined inversely with increasing distance from the emitting electrode in accordance with the predictions of subquantum kinetics. At a distance of 83 cm from the electrode the speed was clocked as high as 2.1 c with speeds as high as 8 c being projected at 65 cm distance! Graphs of the data are published in my book Secrets of Antigravity Propulsion, p. 177 -185. Other than this reporting, Obolensky and myself have not yet taken the time to write up the results for publication in a technical journal due to current demands on our time. Nevertheless, as described in Verification Number 11, our experiment confirmed a key a priori prediction of subquantum kinetics.
4) Also around this time, Eugene Podkletnov and Modanese performed experiments with the Podkletnov gravity impulse beam generator in which they succeeded in sending gravity shock impulses over a distance of 1211 meters at a speed of 64 c. They report their findings in a paper entitled “Study of Light Interaction with Gravity Impulses and Measurements of the Speed of Gravity Impulses” which is appearing this year (2011) in an edited book of papers. E. Podkletnov has disclosed to me in personal communication that they have succeeded in measuring speeds of several thousand c in a higher power impulse beam generator.
5) Dr. Panos Pappas has recently continued experiments on superluminal pulse propagation in his own laboratory in Athens, Greece. He reports the results of his work on his papimi.gr website.
In addition to the above there are various reports of superluminal signal propagation over very short distances such as the papers by Ishii and Giakos (1991) and Enders and Nimtz (1993)."
