content: There was a Brazilian catholic priest (Roberto Landell de Moura) that succeeded in transmitting radio waves in 1894, but his ignorant superiors feared he was playing with witchcraft and his fellow countrymen destroyed his lab. He rebuilt it and was granted a patent in Brazil in March 1901, but the government denied support for his work. He moved to US and was granted three patents in 1904 for several wireless communications devices (including light communications).Most references are inportuguese, but a summary in english ishere.Pretty sad what ignorance and lack of vision can do to a brilliant man.

content: Edison and Tesla were well known rivals. Edison liked to "play politics" so to say and was rather confrontational. He blocked Tesla from using a lightbulb similiar to his at a fair and so what did Tesla do, he came up with own original concept instead. I have to wonder what would have happened if Edison had decided to work with Tesla instead of against him.

content: Quote from: Tinkerer on June 02, 2014, 10:48:26 pmWell they did work together. Tesla was first an employee of Edison. But when Tesla presented Edison his AC concepts and some of his early experiments he showed no interest and refused to let Tesla any further development, so Tesla left on bad terms to become a rival with the backing of Westinghouse. So I think it was not so much politics but rather bad blood from the split up.

content: See the Elephants come again in play poor beasts.Edison will get animals "Westinghoused" by electrocuting them with AC, apparently an elephant was also electrocuted to show how dangerous AC was.BTW Tesla finished the motor for Edison, Edison refused to pay what he promised.Edit: a man that has study Tesla all his life, Eric P Dollard. Although he sometimes goes on tangents, not sure what to make of him. He has a prosecution complex and might be founded or maybe not.Still a fascinating presentation for those interested in Tesla:Edit: @47 mins it gets weird as in nonsense but there are other parts of interest later on regarding radio and the politics.@53 it gets normal again and talks more about history instead of unproven stuff.@1 hour mumbo jumbo about teletransportation still if you ignore what it's impossible the underlying history is still interesting.Feel free to stop then, the rest has some tid bits but it's too long with a lot of stuff that no one will believe. I think it resumes later (way later to history but I can't watch this whole thing to find out where)@1:54 after a lot of explanations about non conventional electromagnetic fields it get interesting again about Einstein and J.J. Thomson. I know it's a bit out there but other than misspoken names here and there he knows his stuff and he is no making any money really, he is pretty much a bum that like to drink at times and climb poles and have some stories that are way TOO fantastic to be true.@2:30 more about history of radio after a lot of unproven speculation of fision.

content: Quote from: Noize on June 03, 2014, 12:29:19 amI agree on the nut thing, but still he has an interesting take on the history of Tesla and the rivalries of the times. The politics of Radio as well among other interesting things.I'm not on the free energy camp, but I don't shut down listening to well articulated people even if they are oddballs.

Morgan!!http://www.imdb.com/title/tt0079985/?ref_=nm_flmg_act_16I can higly recomend this book, can be downloaded as a Kindle..Empires of Light: Edison, Tesla, Westinghouse, and the Race to Electrify the Worldhttp://www.amazon.com/gp/product/B000FBJDA2/ref=oh_d__o08_details_o08__i00?ie=UTF8&psc=1Book DescriptionPublication Date: August 19, 2003In the final decades of the nineteenth century, three brilliant and visionary titans of America’s Gilded Age—Thomas Edison, Nikola Tesla, and George Westinghouse—battled bitterly as each vied to create a vast and powerful electrical empire. In Empires of Light, historian Jill Jonnes portrays this extraordinary trio and their riveting and ruthless world of cutting-edge science, invention, intrigue, money, death, and hard-eyed Wall Street millionaires. At the heart of the story are Thomas Alva Edison, the nation’s most famous and folksy inventor, creator of the incandescent light bulb and mastermind of the world’s first direct current electrical light networks; the Serbian wizard of invention Nikola Tesla, elegant, highly eccentric, a dreamer who revolutionized the generation and delivery of electricity; and the charismatic George Westinghouse, Pittsburgh inventor and tough corporate entrepreneur, an industrial idealist who in the era of gaslight imagined a world powered by cheap and plentiful electricity and worked heart and soul to create it.Edison struggled to introduce his radical new direct current (DC) technology into the hurly-burly of New York City as Tesla and Westinghouse challenged his dominance with their alternating current (AC), thus setting the stage for one of the eeriest feuds in American corporate history, the War of the Electric Currents. The battlegrounds: Wall Street, the 1893 Chicago World’s Fair, Niagara Falls, and, finally, the death chamber—Jonnes takes us on the tense walk down a prison hallway and into the sunlit room where William Kemmler, convicted ax murderer, became the first man to die in the electric chair.Empires of Light is the gripping history of electricity, the “mysterious fluid,” and how the fateful collision of Edison, Tesla, and Westinghouse left the world utterly transformed.But also a peek into this website.. there is a god presentation of Tesla.http://americanbuilt.us/library/nikola-tesla.shtml
