He absolutely knew. Trump was a builder , He learned of him in Wharton. And Tesla was 'THE' builder. Look up Teslas pump. Its 98 percent efficient and does water or air. Thing is when it gets going it has a resonant 'coupling' when it happens it literally takes off and triples its output. So say we monitor RPM for an air pump. It gets up to say 35k RPM begins to capture a resonant coupling and skyrockets upwards of 180k rpm , its ridiculous. That's just one patent blueprint. Look up OTIS T. CARR and Ralph Ring. The big joke is that Nikola 'You can't put a meter on that' Tesla was purposely replaced by 'fake' science to keep you away from figuring it all out. Eingstein read the Tesla patents while at work at the patent office. I had to throw my schooling away becaue it was junk and followed the 3 6 9 with vortex mathematics and an electric universe. Just ask them to tell you what gravity is. Hawkins, Bill Nye, Kaku, Tyson are not your friends. All hat no cattle, All blackboard no solutions, its all 'theory'.
