Wow, yeah, Nicola Tesla was definitely a very smart guy when it comes to using Antiquitech for free energy and many other cool things he's created in his knowledge which is unfortunately being buried from us. If we knew more, if we could study further about this stuff, maybe we wouldn't have to pay an electric bill every month. :P
I believe Albert Einstein wasn't as smart as they say, imo his wife was smarter than him. The school books just want you to believe Einstein is special so they can teach you another dump of useless information by him. Maybe you'll disagree with that, but Nicola Tesla, again, was probably one of the smartest guys to be around and create amazing things for awhile.
Really great post @woelfchen, cheers!
