A neutron beam can destroy electronics and that would be useful in warfare. The U.S. Defense Strategic Defense Initiative put into development the technology of a neutral particle beam to be used as a weapon in outer space. Neutral beam accelerator technology was developed at Los Alamos National Laboratory. According to …

Thermoelectric energy harvesting mainly depends on the operation of the thermoelectric generator (TEG). A thermoelectric (TE) device can directly convert heat emanating from the Sun, radioisotopes, automobiles, industrial sectors, or even the human body to electricity.  A TEG converts heat directly into electrical energy according to the Seebeck effect.   …

Battery usage has expanded from mobile phones and laptops to LED lamps, portable fans, toys, toothbrushes, and even automobiles. Now, the battery applications are expanding further as the Internet of Things, Industry 4.0, big data, mobile and cloud computing are introduced. People build systems to obtain, manage and utilise data …

As computer processors have continued to shrink down to sizes where billions of transistors are on single chip, heat has increasingly become a bigger factor in their performance. If those CPUs did not get as hot in the first place, then much less energy would be needed to keep them …

Heat (i.e., thermal energy) is defined as the energy that is transferred spontaneously between two bodies due to difference in their temperature; heat flows from high to low temperature. There are three main well-known mechanisms for heat transfer: conduction through solid and fluids, convection through fluid, and radiation through solid, …

Naval Warfare depends a large extent on lethality and survivability of submarines, its principal weapon, therefore Navies have been researching new ways to make them quieter and increasing their underwater endurance. Propulsion system plays an extremely important role in the functioning of a submarine for the completion of its desired …

A fuel cell is a device that generates electricity by a chemical reaction. It converts hydrogen and oxygen into water, and in the process also creates electricity. Fuel cells provide many advantages, they are environment friendly as they don’t produce pollutants or greenhouse gasses, significantly improving our environment, high energy efficiency ( …

A directed-energy weapons (DEW) are ranged weapon systems that inflicts damage at a target by emission of highly focused energy, including laser, microwaves and particle beams. Potential applications of this technology include anti-personnel weapon systems, missile defense system, and the disabling of lightly armored vehicles or mounted optical devices   …

The Internet-of-Things is an emerging revolution in the ICT sector under which interconnecting physical objects communicate with each other and/or with humans over internet in order to offer a given service.  The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people …

A battery is an electrochemical device that stores electrical energy as chemical energy in its anode and cathode during the charging process, and when needed, releases the energy as electrical output during the discharge. An ideal battery is expected to have high specific energy, high power density, long cycle life, …
