The ocean absorbs energy from the sun, stores it, and then releases it slowly. Sounds like a prescription for meeting the world's energy needs, since the ocean is the largest feature of our planet. But can ocean energy be tapped in a way that doesn't ...

When a current passes through a material that conducts electricity it generates heat. Understanding where the temperature will rise in an electronic system helps engineers design reliable, high-performing computers, mobile phones and medical devices.

"Solar thermal energy is considered to be one of the most promising energy sources," explained Isoird. "Due to the fact that solar radiation is a time-dependent energy source, energy accessibility and demand often do not match. Thermal energy storage ...

For instance, in the case of thermal energy transfer, an initial spark can create a flame. As that flame heats material - say, the trunk of a tree - the material begins to burn. The energy given off by the burning process heats the surrounding area ...

Fuel combustion creates acidic nitrogen oxide gases that irritate the lungs. Vehicles are the main problem, giving rise to the brown haze that hangs over polluted cities. Nitrogen oxides also react with other pollutants to form ozone. Although the ...

The technology uses tiny resonators made of self-scaled structures called fractals to form a virtual bridge to lead heat, or other electromagnetic radiation forms, controlling flow from one area to another. The resulting 'heat transfer' happens at the ...
