Waste heat recovery is a significant opportunity – in 2015, 59.2 quadrillion BTU of energy was wasted mainly in the form of heat. Much of the waste heat has been characterized by its source and its ...

MIT researchers have a new energy storage design that will store heat generated by excess electricity from solar or wind power in large tanks of white-hot molten silicon. It converts the light from ...

Researchers have found a new way to improve a key element of thermophotovoltaic systems, which convert heat into electricity via light. Engineers designed a thermal emitter that can deliver high ...
