Waste heat is by necessity produced both by machines that do work and in other processes that use energy, for example in a refrigerator warming the room air or a combustion engine releasing heat into the environment. The need for many systems to reject heat as a by-product of their operation is fundamental to the laws of thermodynamics. Waste heat has lower utility (or in thermodynamics lexicon a lower exergy or higher entropy) than the original energy source. Sources of waste heat include all manner of human activities, natural systems, and all organisms. Rejection of unneeded cold (as from a heat pump) is also a form of waste heat (i.e. the medium has heat, but at a lower temperature than is considered warm).
Instead of being “wasted” by release into the ambient environment, sometimes waste heat (or cold) can be utilized by another process, or a portion of heat that would otherwise be wasted can be reused in the same process if make-up heat is added to the system (as with heat recovery ventilation in a building).
This short infographic video describes how industrial waste heat is converted to emission-free power. Update: Since this video was made in 2013, DOE has determined the total US WHP potential is 15 GW, 50% more than the previous estimate of 10 GW referenced in this video (at 15 sec). The video provides an excellent overview of of WHP opportunities, technologies and barriers.
Dr. Stafford's talk discusses his ideas of using nanotechnology to convert waste heat into electricity. In particular, he shows how we might take advantage of quantum oddities in the way heat is transferred across specific atomic structures, so that we could produce cost-effective, non-polluting electricity. Dr. Stafford is a Professor of Physics at the University of Arizona. He is also Co-Director of the UA Chemical Physics Program. For over twenty-five years, Dr. Stafford has focused his research on the theory of charge and heat flow in quantum systems. He has published over seventy peer-reviewed scientific articles, and he holds three U.S. Patents for inventions in nanotechnology. In 2000, he received the ABB Prize of the Swiss Physical Society “for his outstanding contributions to re...
Every day, heat is released into the atmosphere from boilers, generators, exhaust stacks, ovens and kilns in industries such as waste management and processing, metals, mining, lime and oil. GE's Clean Cycle 125 kW heat-to-power generator can turn that heat into reliable, base-load electricity. The conversion process, called the Organic Rankine Cycle (ORC), generates no additional emissions and requires no additional fuel ... just heat. GE's Clean Cycle generator suits a variety of industries including oil & gas downstream/refining; waste management (wastewater and landfill); food and beverage, and pulp and paper. See how GE's Clean Cycle generator takes waste heat from a Jenbacher gas engine running on landfill gas and transforms it into additional electricity. GE's Clean Cycle he...
Green Machine works on the principle of ORC (Organic Rankine Cycle) for the use of waste heat that is converted into electrical power. The Green Machine unit produces fuel-free and emission-free electricity from process and waste heat from as low as 80 °C. The Green Machine consists of a proven, patent-protected rotary twin screw expander. The Green Machine produces electricity, which is transformed from a source of low-temperature waste heat from BGS cogeneration units, and offers a very good return on investment. http://www.cogenera.si/ info@cogenera.si

In 1960 two seminal papers in SETI were published, providing two visions for SETI. Giuseppe Cocconi and Philip Morrison’s proposed detecting deliberate radio signals ("communication SETI"), while Freeman Dyson ("artifact SETI"), proposed detecting the inevitable effects of massive energy supplies and artifacts on their surroundings. While communication SETI has now had several career-long practitioners, artifact SETI has, until recently, not been a vibrant field of study. The launch of the Kepler and WISE satellites have greatly renewed interest in the field, however, and the recent Breakthrough Listen Initiative has provided new motivation for finding good targets for communication SETI. Dr. Wright will discuss the progress of the Ĝ Search for Extraterrestrial Civilizations with Large E...

http://www.EngineeringTV.com The Cyclone Waste Heat Engine (WHE) is a self-starting engine that operates in a low pressure, low temperature range. This feature allows the engine to run on waste heat emanating from an external source, such as the exhaust from an internal (or external) combustion engine, or the direct burning of biomass (i.e., processing garbage into methane would not be required). The Waste Heat Engine is also designed to run efficiently on solar heat without the installation of costly photovoltaic panels. Commercial applications for the engine include boosting the power and efficiency of large gasoline or diesel-powered generators. When installed to the exhaust system of an engine that can generate over 1000 degrees of heat, the WHE could materially increase overall...

Roughly one-third of the energy consumed by industry is wasted as a result of inefficiencies in heating processes. This "waste heat" can be used to offset additional thermal loads through the use of heat recovery systems. Our workshop will help you identify the economic feasibility of implementing various heat recovery measures and provide practical examples of how these measures have contributed to significant energy savings for our customers.
