Tesla a Man out of Time : imagine possessing the ability to develop electrical technologies so powerful so advanced that nobody  can understand them. Even he wrestled with the value and danger his inventions bequeathed mankind? This was Tesla's dilemma.
He ushered in the second industrial revolution and because of him you can provide the energy system that makes our world today the best humans have ever experienced.
His ideas of extracting energy from the ionosphere, changing the climate, and the wireless long distance transmission of electricity have yet to be exploited.
