wastedspark
Wastedspark is a term used to describe a class of technologies and design approaches aimed at extracting energy or value from waste streams that would otherwise be discarded. It emphasizes turning residual energy, heat, motion, or materials into usable power, heat, or resources, and is often linked to the broader goals of energy efficiency and the circular economy. The concept is used in both academic literature and industry discourse as an umbrella for multiple technologies rather than a single device.
Technologies commonly associated with wastedspark include thermoelectric generators that convert temperature differences into electricity, piezoelectric harvesters
Applications include manufacturing and processing facilities seeking to reclaim waste heat, data centers and electronics that
Etymology: a portmanteau of waste and spark, signaling the ignition of value from discarded sources.
