Along the way, he shifted his focus away from specific inventions and began looking at and identifying underlying principles and hidden environmental inputs that make these machines work. Now, after 46 years of studying how to tap into energy sources freely available in Nature, he is semi-retired and continues his private research.
In 2000, he started his own company, Clear Tech, Inc., and began publishing information on the working principles of various free energy systems. Besides his free educational website, some of these publications include: The Free Energy Secrets of Cold Electricity (2000), Tesla’s Radiant Energy (2006), Electric Motor Secrets (2007), Perpetual Motion Reality (2012), Open System Thermodynamics (2013), the Bedini SG Handbook series (2012-16), Free Solar Secrets (2014) and many others. After 4 decades in the field, Dr. Lindemann continues to be a sought after public speaker and educator.
