Paperback. Condizione: new. Walker, David K. (illustratore). Paperback. Conversion of electrostatic energy from the air is an unexplored area of science, even though Benjamin Franklin invented the first electrostatic motor in 1748, which is detailed in this book so the reader can make his or her own. The earth's electric field, at over 100 volts per meter, is a natural source of electrostatic energy or in other words: free electricity. However, the utilization of that atmospheric electricity, with electrostatic motors and airborne antennas, has been an elusive and neglected art from the last century. With the earth's ionosphere charged up to almost 400 thousand volts (kilovolts), the author notes that the higher the antenna, the higher the voltage that is accessible for any electrostatic motor. Professor Oleg Jefimenko, an amazing genius, physicist, and inventor, wrote this unique book describing his experiments with many electrostatic motors. He carefully documented each one with drawings and photos, explaining their construction and materials used. In this new edition, a few of Jefimenko's articles are added that will help the reader to construct his/her own electrostatic motor and thereby experiment with free electricity from the earth's atmosphere. This is an exciting book to read and the history is surprising. encouraging the reader to learn more, try to build one, and share the knowledge. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.
