Thermal, Propulsion & Energy

A rocket is defined as a technologically advanced reaction motor that can carry its oxidant to propel a launch vehicle. A reaction motor is used as a propulsion device to generate a forward push by expelling the rocket structure in a backward direction. A missile is an unmanned rocket vehicle. …

The International Energy Agency’s has found that the accelerating demand for electricity – due to a growing global population and rising levels of affluence – is on course to outpace the growth of renewable energy and increase reliance on fossil fuels.   The International Maritime Organization has adopted mandatory measures …

The potential use of nuclear weapons poses the greatest danger to U.S. security. According to the U.S. National Security Strategy, Recently Nuclear threat is rising again due to nuclear arms race in asia, modernisation of  nuclear arsenal by Major and regional powers, statement by countries like North Korea to use …

Vehicles propelled by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidizer, unlike most combustion engines, so rocket engines can be used in a vacuum to propel spacecraft and ballistic missiles. Compared to other types of jet engines, rocket engines are the lightest and have the highest …

A new  power revolution is going on in orbit – that of electrical propulsion for satellites. 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 …

Millimeter waves are electromagnetic signals with frequencies ranging from 30 to 300 GHz that correspond to wavelengths of 10 to 1 mm in the free space. Electromagnetic waves in the millimeter-wave band  (with frequencies between 30 and 300 GHz, or wavelengths between 10 and 1.0 mm) have attractive characteristics. One of …

The current global energy system is both unsustainable and inequitable, and large changes are required quite rapidly if there is to be any chance of limiting the effects of global warming. The global community has agreed on sustainable development goals attempting to integrate and balance the three dimensions of economic, …

Since the Industrial Revolution, the environmental impacts of energy have posed a concern. Recently, this has driven researchers to search for viable options for clean and renewable energy sources. Due to its affordability and environmental friendliness, hydrogen is a feasible alternative to fossil fuels for energy applications. However, due to its …
