When the free electrons absorb heat energy, they gain kinetic energy and move much faster. As they move through the metal, they crash into the metal ions. Some of their kinetic energy is absorbed ...

On a much larger scale, solar-thermal power plants employ various techniques to concentrate the sun's energy as a heat source. The heat is then used to boil water to drive a steam turbine that ...

An international research team led by the Universitat Politècnica de Catalunya—BarcelonaTech (UPC) has created a hybrid ...

These findings contribute to developing objective methods for evaluating thermal comfort. The brain discriminates between hot and cold sensations by inducing distinct temporal activity patterns in ...

But all that is about to change, as the family joins a small-yet-growing group who are tapping into a network of underground energy to heat and cool their homes. Massachusetts, like the rest of ...

These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly. 4 min read Geothermal energy has been used for thousands of years ...

We model the thermal evolution and activity of comet 9P/Tempel 1, in anticipation of the Deep Impact mission encounter with the comet. We also investigate the possible outcome of a projectile impact, ...
