Michael Sykes’ invention, U.S. Patent No. 6,933,016, is technology to turn a piece of wood into a thermal battery. Wood is no longer just a structural member, or just a decorative trim or paneling- it becomes a solar energy storing device, and when the house is properly configured and sited it can heat and cool itself. Obviously, the more wood the better, so the invention is especially applicable to solid wood homes. This energy from a shift-in-time is called “Enertia®” a word, like the word “Laser,” that Sykes made up and trademarked to describe the phenomenon. Enertia® Building Systems has developed a line of solid Gluelam wall homes to maximize the energy-storing potential of the wood, and to offer the mainstream appearance necessary to attract traditional housing buyers. The homes can be seen on the Enertia® website at www.enertia.com.
