"Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays."

An amplifier’s job is to take a weak audio signal and boost it to generate a signal that is powerful enough to drive a speaker, or in the above case, an electric motor. Today the component at the heart of most amplifiers is the transistor. Transistors have replaced Tesla’s vacuum tube (also called valve amplifier)."

"The supercapacitor is an electrostatic device that comes with a huge capacitance due to its constructional feature, that is, the electrodynamic double layer. Since its operation is like any other capacitors, it can be discharged/charged endlessly unlike the batteries that show degradation with the increasing cycles of operation. Hardly the supercapacitor degrades to 80% of its rated capacity over a duration of 10 years."

"capacitor banks rated at 5KVA each. Tesla used twelve (12), for a total of 60KVA (KW), while Gray used three (3) for a total of 15KVA.
The key design point for Tesla’s car system was that his power rating of 60KVA equates to 80HP so that all of his design specifications match the full power rating for his car."
