Nikola Tesla was well before his time. His ideas are still to be put into existence. A truly remarkable person. I am a big, big admirer of Nikola.
Unfortunately, as it happens with all big personalities who are not rotten enough to survive, he was at mercy of the sharks. FBI included.
His schemes were intently vague and separated because he was in constants fear of what would happen if they end up in wrong hands. Which they did after his death.
With Tesla living in a morally better society (wishful thinking of mine) we would be now skipping the planets and be hailing from distant stars. Our mother planet would be heaven.
You've mentioned his way of imagining design which is similar to Einsteins. This is the alpha way with your brain functioning at approximately 10 Hz. This way you can connect left and right hemisphere and achieve cooperation between imagination and logic. Not everybody can do this :) But you can train and get results. Check out Ultramind method by Jose Silva. It will fascinate you.
