To eliminate undesirable harmonics in power lines, active harmonic filters are deployed. In effect, these filters cancel out undesirable harmonics that damage equipment by creating, in real-time, equal and opposite wave forms, similar to the principle of noise cancellation in airplane earphones.
This author is writing a book on an aspect of harmonics related to the Internet of Things (IoT), focused on the future control, automation and optimization of auditory and THz frequencies, including music. The book draws on a multi-millennia history of harmonics from Sumer to Phoenicia to ancient Greece (featuring the mysterious Pythagoras cult) to the Hallstatt Celts to modern Ireland. It features a west European town in an ongoing transition to a "smart town" using an IoT network with distributed control, and proposes a dynamic frequency cloning technology application to harness renewable energy sources in a bid for regional energy self-sufficiency.
The application requires the development of an advanced, very finely tuned, real-time resonator that targets ultra-narrow frequency bands within auditory and non-auditory spectra. Usually, resonance is something to be avoided, but for these applications resonance is sometimes deliberately created. More on this in future posts.
The book will be available in 2018.
