No new material eh, Abes? You posted a link to that Tesla video a year or more ago.
Hmm, just a thought, but that video constantly bemoans the fact that nobody has ever heard of Nikola Tesla and that he is all but forgotten. Is he really that obscure? I remember learning about him in school and being fascinated with him ever since. He also pops up in popular culture fairly often. The video game Red Alert has been using his name from the early nineties until present, with the most recent game in the series coming out just a couple of years ago. The film The Prestige featured him as an important character to the plot (though a very sciencefictionized version of him), and Fallout 3 features a book you can find lying around the wasteland called Nikola Tesla and Me, that increases your science skill when read.
Throughout my whole life he has never been that obscure, yet I constantly hear about how very obscure he is.
As for Philo Farnsworth and Dr. Rife: I remember reading about Farnsworth as a child and always being really sympathetic to him. Always having been a bit of a Neo Luddite, even as a child, I absolutely loved the idea of the man who invented the television living to deeply regret it. He is definitely obscure, and deserves more credit, though perhaps not as much as some of his supporters claim.
Dr. Rife on the other hand... there is absolutely no reason to believe the man's "cure for all diseases" ever worked. In fact, consider the "too good to be true" factor of that claim. Cures all diseases? You know what they say about things that are too good to be true... they usually are. So, Rife's claims were unable to be replicated (meaning, they didn't work) and so were rejected. Rife, not appreciating rejection, apparently, claimed it was a conspiracy among the AMA to discredit him and suppress his research. The only reason we even know Rife's name today is because people are drawn to a good conspiracy theory, coupled with the warm fuzzies one gets from the thought that there is a single cure for every disease. I'd like to believe that was true too, it would be amazing. But it was an outrageous claim that the claimer was never able to substantiate, so there is no reason to grant it any validity.
