When it comes to free energy, we have to mention a great inventor-Nikola Tesla.
A hundred years ago, Mr. Nikola Tesla had already studied the means and methods of obtaining free energy. His Wardenclyffe Tower project was the first step towards realizing free energy.
Regrettably, his Wardenclyffe Tower later lost funding and was demolished during World War I, leaving the world with infinite regret.
Mr. Nikola Tesla is a great man forgotten by the world. He invented the AC motor. If he had not given up the patent rights of the AC motor for the world to use for free ($2.5 per horsepower), he would be the richest man in the world.
Mr. Nikola Tesla is a great inventor full of humanistic spirit. His dream is to provide the world with inexhaustible energy. When it comes to free energy, we have to mention Nikola Tesla. His contribution to free energy will definitely affect mankind, and mankind will always remember him.
