Scientists in Japan have developed a new organic device that can harvest energy from heat. Unlike other thermoelectric generators, this one works at room temperature without a heat gradient. Usually, ...

By Sean Mowbray A small floating pilot device deployed off the Canary Islands could one day prove pivotal to unlocking clean ...

The past decade has seen significant advances in distributed sensors and sensor networks. With these advances has come an increased interest in energy harvesting to provide a continuous power source ...

For the hot end, an aluminium mount was pressed into soil, transferring the Earth’s ambient heat to the engine’s bottom plate ...

When room-temperature washers are placed in hot water, the temperature of the washers increases and the temperature of the water decreases. Energy from the water is transferred to the washers. When ...

What's the difference between warm air and cool air? In fact, what does “temperature” even mean? It's stranger than you think. At a basic level, if you increase the temperature of air, you increase ...

Ditch fossil fuels in less than half the time and save half a billion dollars or more on what you would otherwise spend to decarbonize. That’s the pitch a group of students, alumni and faculty will ...

UK researchers have designed a pumped thermal energy storage system for large-scale grid electricity, stored as high-grade thermal energy. It is based on a Brayton PTES concept demonstrated by ...
