Usually I hate people who comment only with "I stopped reading at...", but in this particular case I'll make an exception. For myself.

I stopped reading at:

"As far as I know, no book on the history of physics mentions Tesla"

which is a statement approximately as correct as "As far as I know, no book on the history of the United States mentions Woodrow Wilson"

Not based on the linked article, which is horrible. I gave up when it was simultaneously trying to claim that the ether exists but space can have no properties.

The author could have done a better job of explaining this, if he would have said "Einsteinian Space" rather than "space" in that section. That's fairly easy to infer from the context, but it could have been explained better. Einstein viewed "space" as a vacuum. Tesla argues that view is flawed, that nothingness by definition can't have any properties, and as a result can't bend, because there's nothing to bend. He proposes aether/ether as an alternative explanation of "space".

If all that we're talking about is terminology then the entire article is pointless.

What a steaming pile of junk.
