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 …

Hydrazine has dominated the space industry as the choice of propellant for over six decades, due to its high-performance characteristics, despite its environment and health hazards and the challenges faced in its manufacturing, storage, ground handling and transportation. Hydrazine based propulsion systems are state-of-the-art for various applications ranging from launchers to …

Researchers from US, Europe, Russia, China, Germany and Japan are striving towards harnessing immense energy of nuclear fusion, the process that powers the Sun and produces 10 thousand times more energy than coal. The idea is to recreate the nuclear fusion that occurs in stars, where atomic nuclei collide and …

Current military threats have created a tremendous requirement for mobility for successful execution of missions. Therefore military is now in a rapid transformation to become a lighter, more agile, mobile, networked and more lethal force. To become more lethal and better networked involves new weapons systems and more sophisticated electronic …

3D printing or additive manufacturing is ongoing revolution in manufacturing with its potential to fabricate any complex object and is being utilized from aerospace components to human organs, textiles, metals, buildings and even food. Additive manufacturing is defined by ASTM International as the process of joining materials together, layer by …

An ion thruster is a form of electric propulsion used for spacecraft propulsion. It creates thrust by accelerating ions with electricity. As the ionised particles escape from the aircraft, they generate a force moving in the other direction. Power supplies for ion thrusters are usually electric solar panels, but at sufficiently …

Russia has launched the world’s only floating nuclear reactor, beating countries like the US and China to the post. The Akademik Lomonosov was set off from a port in St Petersberg and has arrived at Murmansk, a town in Northwest Russia. In Nov 2018, it was reported that Russia’s floating nuclear …

Renewable energy is at the centre of the transition to a less carbon-intensive and more sustainable energy system. Renewables have grown rapidly in recent years, accompanied by sharp cost reductions for solar photovoltaics and wind power in particular. “By 2020, wind power could prevent more than 1 billion tonnes of …

Batteries are  critical for military missions since mission success and soldiers’ lives often depend directly on a military battery’s performance.  As military platforms and systems such as land vehicles are fitted with more electronic equipment, their electrical energy demands will continue to increase and it is anticipated that their limited electrical …

World economic growth will lead to  strong energy demands and consumption.  U.S. Energy Information Administration’s latest International Energy Outlook 2017 (IEO2017) projects that world energy consumption will grow by 28% between 2015 and 2040. Most of this growth is expected to come from countries that are not in the Organization …
