"The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes"

"Electromagnetic radiation is categorized using the electromagnetic spectrum, which is normally ordered by frequency. The visible light frequency is 400 THz to 700 THz, approximately. A THz is a Terahertz, which is a unit of frequency equal to one trillion Hertz."

"the source of energy that powered Tesla’s electric car in 1931 was energy harvested from EM waves that is everywhere this type of electric car had unlimited range.
Tesla used an antenna to capture this free energy"

"Our Sun emits electromagnetic energy and that energy showers down on us throughout the whole 24 hours, and if a energy receiving device (an antenna) can easily be built to harness and use this power"
"Tesla was able to amplify and convert the invisible electromagnetic radiation"
