Quantum batteries are energy storage devices that utilize quantum mechanics to enhance their performance. They are characterized by a fascinating behavior: their charging rate is superextensive, meaning that quantum batteries with larger capacity actually take less time to charge. This article gives a theoretical and experimental …

Dimplex say their tests have shown savings of 47% against electric radiators. However, the key here is that they are way more efficient than other storage heaters, or electric convection heaters – but the cost of electricity (per unit) is still far more higher than gas. You should only ever rely on storage heaters if you cannot get a gas ...

Quantum friction, a quantum analog of classical friction, reduces the performance of quantum machines, such as heat engines, and makes them less energy efficient. We here report the experimental realization of an energy efficient quantum engine coupled to a quantum battery that stores the produced work, using a single ion in a linear …

Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. TES systems are used particularly in buildings and in industrial processes. This paper is focused on TES technologies that …
