"Just as optical telescopes collect visible light, bring it to a focus, amplify it and make it available for analysis by various instruments, so do radio telescopes collect weak radio light waves, bring it to a focus, amplify it and make it available for analysis."

"The radio "receives" these electromagnetic radio waves and converts them to mechanical vibrations in the speaker to create the sound waves you can hear."
"Radio telescopes can also detect quasars. The term quasar is short for quasi-stellar radio source. The name comes from the fact that the first quasars identified emit mostly radio energy and look much like stars. Quasars are very energetic, with some emitting 1,000 times as much energy as the entire Milky Way."

"Antennas receive an electromagnetic wave and convert it to an electric signal"

"The box had an antenna sticking out. Tesla would fool with some tuners and tune in the right frequency and got 240 volts delivered through the air"

"The sun, as well as other sources of radiant energy throw off minute particles of matter positively electrified, which, impinging upon the upper plate, communicate continuously an electrical charge to the same."
"The attractive features of the cosmic rays is their constancy. They shower down on us throughout the whole 24 hours, and if a plant is developed to use their power it will not require devices for storing energy as would be necessary with devices using wind, tide or sunlight."

"An ignition coil (also called a spark coil) is an induction coil in an automobile’s ignition system which transforms the battery’s low voltage to the thousands of volts (around 10 – 20kV) needed to create an electric spark in the spark plugs to ignite the fuel. It is also entirely plausible that Tesla used the Pierce Arrow’s ignition coil to transform the antenna receiver’s low voltage to hundreds of volts needed to power the electric motor. AC electric motors requires more than 12 volts of AC current. It doesn’t need 10-20,000 volts. So all Tesla needed to do is use the Pierce Arrow’s ignition coil to transform the very weak signal captured by the antenna (an electrical device which converts electric currents into radio waves, and vice versa.) into a constant 120 volts"
