Don Lloyd is an electrical engineer now retired from Honeywell after 35 years in marketing, engineering and project management. He has extensive experience in taking complex subjects (such as laser gyroscopes or mosaic infrared detectors) and explaining how they work in terms understood by the general public. He is at his best when giving lectures describing how geothermal heat pumps work and why they are the ideal heating and cooling solution for homeowners. Prior to entering the geothermal world, he operated his own software consulting business as a Microsoft Certified Software Professional. He also served as an officer in the US Army. Don lives in the Hudson River Valley region of New York State with his wife, artist Martha Lloyd, in their new home where the oil trucks pass by but never stop. Installing a geothermal heat pump was one of the best decisions I ever made! Lawrence A. Muhammad is an International Ground Source Heat Pump Association (IGSHPA) Certified National Trainer, having conducted numerous trainings throughout the US. As a community college professor, he teaches a wide variety of geothermal courses at three colleges in Michigan. Putting his teaching and training skills to work, Lawrence is also a licensed residential builder, an IGSHPA Accredited Installer, a NATE Proctor, and the designer / developer of the apprenticeship program for the Geothermal Innovations Gii4 proprietary heat exchanger. His geothermal training company, Geo NetZero, is committed to providing a skilled and qualified workforce throughout America.
Lloyd makes a complex subject accessible and helpful to a broad
audience, from interested homeowners to system installers. A solid
addition to all "renewables" collections. - Robert Eagan, Library

"We each must do our share in ensuring that future generations have
safe and clean energy sources while not compromising our comfort or
budget. Geo Power shows how that is possible with ground-source
heat pumps. With this book, my students and trainees are able to
understand not only why geothermal can be used, but the scientific
reasons and evidence for its effectiveness. And for homeowners
looking for a safe and sustainable alternative to fossil fuels, or
businesses needing to reduce operating costs, this is the right
book at the right time."- Lawrence A. Muhammad, IGSHPA Certified

"Geo Power is especially designed to help spread the word about
ground-source or geothermal heat pump systems (GHPS) to the world,
and it does an excellent job of explaining how a GHPS works for
health, safety, heating, cooling and hot water. I recommend reading
Geo Power to understand the most energy saving comfort system for
your home or commercial property."- Gerald R. McClain, Distance
