Most machines lose up to 60% of the intake energy to surround through heat. The global waste heat recovery system(WHRS) market was valued at $54.3 billion, and the petroleum refinery segment accounted for the largest market share.
The cost and maintenance issues associated with wireless sensor battery replacement are intractable and immense. In addition, the negative environmental effect of wasted battery metals is something to be reckoned with soon. Current battery-operated wireless sensors have a lifespan of only 1 to 2 years, making replacement and maintenance expenses. In industrial applications with hundreds or thousands of potential sensor locations, a battery replacement cost can be as high as $500, bringing it to over $2,000 per IoT sensor over a 10-year lifespan.
As a solution, Abundant industrial waste heat can be utilized as an energy source to power the IoT.
