"The key to unlimited free home energy is erecting the antenna above head height. Why? Physicists have determined that the earth has a negative charge which amounts to 400,000 columbs, yet six feet above the ground (above head height) the air is charged with more than 200 volts positive in respect to the ground. Your electrical outlets and home appliances are charged with 120 volts positive. An antenna is a free energy receiver. It receives free radiant energy and converts it into electric current. So an antenna erected on the roof of a house will tap into and immediately start receiving this free and infinite supply of 200 volts positive energy."

"Stick an antenna up in the air, the higher the better, and wire it to one side of a capacitor, the other going to a good earth ground, and the potential difference will then charge the capacitor."

"Electromagnetic (EM) waves which Tesla declared is a free source of power that is “everywhere present in unlimited quantities”."

"Antennas transmit and receive electromagnetic waves. Generally composed of metals (mainly copper or aluminum), antennas can convert an electric current into electromagnetic radiation and vice versa."
