I happened across one of those Tesla Cyber-Trucks yesterday, and just a few hours later was listening to a conversation with my late, great friend Hillary Raimo, who spent a week at Tesla. No, not the Elon Musk EV factory, but rather the rooms that one of the greatest inventors-Nikola Tesla-lived in the last years of his life. Hillary's stay revealed the three secrets of the universe...that are available to everyone, free of charge (no pun intended.)
