Publisher's Synopsis
100 Great Perpetual Motion Machines and Other Inventions Arranged Alphabetically:
This is what may be the first nearly complete tome of working free energy inventions. 50 Great Flying and Underwater Perpetual Motion Machines are saved for a second volume. Nathan Coppedge is an inventor like no other. Most of these creations are of Nathan's own invention, replete with simple as-easy-as-it-gets mathematics. Many of the diagrams provide critical information on how to possibly build the devices and make them work.
