The phenomenon of resonance is a broad concept that comes into play in almost every aspect of life. It can manifest on many levels from simple mechanical vibrations and oscillations (often unwanted), down to sub-atomic levels such as the precession of atomic nuclei, or 'shaking' of atoms. Materials on our website detail how certain resonances can be utilized to produce excess energy in the form of electricity and/or heat.
